The stroke syndromes. most common is middle cerebral artery. Key Loc=loss of consciousness Bulb= memory Spiral= confusion These are intact in MCA..only in ACA memory is affected hence the bulb is crossed out. Divide the body in 4 boxes representing upper and lower limbs and each box is further divided into S (sensory) M (Motor). The dark shading means this is affected more. Dotted shading means affected to a lesser extent. Note how sensory is intact (not shaded) in webers and benedict . The red dot in brain = site of infarction The 2 circles represent visual field. ( intact in ACA). Only ACA has urinary incontinence (shown by leaking urine) Note. For Benedict. .Ataxia is shown by shading under the legs on one side (although legs are represented by boxes the stick lines as legs is only used to represent ataxia). tip..whenever faced with an infarct question draw the man and symbols shown and shade accordingly. Will definitely help diagnose the case quickly.

Introduction This post describe the creation of a Stroke Summary video. The aim of this project was to assess the attitudes of medical students towards the use of video animation in medical education. An educational tutorial was produced outlining the basic principles of stroke. This aimed to provide a summary of different aspects relating to stroke, outlined in the Bristol University curriculum. This intended to be a short, concise animation covering stroke presentation, definition and recognition, with an overview of the blood supply to the brain and the classification of stroke presentation used in clinical practice. This was followed by some key facts and a summary of different management stages. After the video animation was produced an assessment of student’s attitudes using an online questionnaire was undertaken. This consisted of ten short questions and an open text feedback for additional comments. The video was then edited with reference to feedback given by students and the results analysed. This report will outline relevant research and project work that lead to this assignment being undertaken. A description of the method followed to generate the video animation and to collect feedback on students will be outlined followed by analysis of results. This will then be discussed in relation to previous work and research. Background There are a number of reasons this project has been undertaken. On a personal level, I have a long-standing interest in teaching and medical education. As part of a previous project I created a series of audio tutorials in cardiovascular medicine and assessed student attitudes to audio learning. The findings of this report showed that a large number of students found these audio tutorials useful and would like more of these available to supplement their learning. One of the questions given to students at this time assessed how useful they found different types of educational material. This project showed students reporting audio tutorials more useful than previously thought, while also reporting that they were not readily available. Although a video tutorial was not provided to them at this time, feedback questions assessed attitudes to video tutorials as a learning resource. Students reported low availability and felt they would be more useful than audio tutorials. Some results from this project are shown in figure 1. Figure 1. Results from previous research by Buick (2007), showing attitudes of students towards different learning tutorials. The majority of students report audio tutorials to be ‘quite useful’ or ‘very useful’. Video tutorials are thought by students to be more useful that audio tutorials, however there is a large proportion that do not have access to these learning resources. As a number of students reported an inability to access to video tutorials, it was thought that creating a video animation tutorial followed by assessing students attitudes would be a useful follow up project. If this is found to be a useful resource, other students may generate video tutorials in the future. Therefore student feedback also assessed attitudes towards authenticity, relating to who generates the tutorial and whether they find the ability to feedback a useful tool. Medical education is widely researched globally, although it is not often a consideration for those studying medicine. Those involved in teaching and educating future doctors have looked at different methods of passing on knowledge. A high quality medical education given to future healthcare professionals is important. It is widely accepted that a better knowledge results in better care for patients and education is at the centre of any healthcare system. This is reflected in the cost of educating medical students and training doctors in the UK. In the 1997 it was reported by the Department of Health that estimates of 200 million pounds would be spent per year for an increase in 1000 medical students being trained in the UK. This suggests that the cost of training a medical student is in the region of £200,0001. Medical education in the UK is split in two halves, with undergraduate and postgraduate training. The Department of Health has recently invested millions of pounds into the development of online tutorials for postgraduate training posts in a number of different specialities. Justification for is given by reducing the cost of training through the use of standardised online tutorials. This will be a more cost effective method than the standard in hospital teaching. This approach has not been undertaken for undergraduate medical education. Universities are seen as primarily responsible for undergraduate training. Many of these institutions have used the Internet to aid teaching and have produced video tutorials. However, as reflected in the previous project (Buick, 2007), resources are often limited and students do not feel they have ready access to these educational tutorials. The benefits of different types of learning resource have been researched. These include online audio downloads (Spickard et al, 2004), practice exam questions and interactive tutorials (Hudsen, 2004). Research showing the benefit of video was shown by Balslev et al (2005) comparing video and written text while teaching a patient case. Balsley et al (2005) found those who learnt using a video presentation rather than those given written text showed a significant increase in data exploration, theory evaluation and exploration. However, there is little research looking specifically at video animation for explaining conditions. Animation software is now available on personal computers and is also possible using Microsoft PowerPointTM, which is the most widely used presentation software. It is clear that recent trends show training can benefit from this type of learning resource. Generation of high quality video tutorials can help students learn while reducing the cost of training. It is for this reason that more material is likely to become available, either from funded production supported by external organisations or by the trainers and trainees themselves who have technology able to produce material such as this on their home computer. Ethical and Legal Issues During the development of this video some ethical and legal issues arose that had to be addressed before a final video could be made. When considering what imagery would be used in the video, I wanted to include pictures of clinical signs relevant to the audio narration. However, taking images from the Internet without prior consent was not thought to be ethical and therefore clinical signs were displayed graphically through drawings and diagrams. Plagiarism and copyright were some of the legal issues surrounding the presentation of medical information. Narrated information was generated using a number of information sources, none of which were exclusively quoted. Therefore an end reference list was generated showing all supporting information sources. Images used in the animation were either self generated or taken from sources such as Wikipedia.org. This resource supplies images under a free software license such as GNU general public license2. This allows anyone to freely use and edit images while referencing the original source. Skills Needed To Develop This Video Animation To generate the video a number I had to develop a number of new skills. Unlike previous work that had been undertaken this media was generated using animation software. To use this effectively I had to research the different functions that were available. To do this I combined reading books aimed to teach beginners such as Macromedia Flash 8 for Dummies (Ellen Finkelstein and Gurdy Leete, 2006) and online sources such as www.learnflash.com . To generate voice narration, another program was used that allowed editing and splicing of audio tracks. This was then split up into a number of narrated sections and added to the animation. Method Script To produce the tutorial the first stage was to construct a script for narration. This involved outlining the areas to be covered. The main headings used were: Stroke definition This gave a clinical definition and a lay person recognition mnemonic called FAST which is used to help members of the general public recognise stroke. Pathophysiology This covered blood supply to the brain. This combined diagrams of the circle of Willis, with images of the brain. Arterial blood supply were then displayed over the brain images while relating this to the arterial vessels leaving the circle of Willis Classification Students at Bristol university are asked to understand the Oxford / Bamford classification. This was covered in detail with explanations of clinical signs that may be seen and graphical representation of these. Prevalence This section covered prevalence, national impact and cost of stroke in the UK. Management In this section management was split up it to immediate management, medical management, in hospital care and some of the procedures considered for different cases. Risk factors for stroke and research into this was also written up and narrated. However at a later stage this was not included due to time constraints and video length. Narration An audio narration was generated using software called ‘Garage Band’ which allows audio tracks to be recorded and edited. The narration was exported in 45 sections so that this could then be added to the animation at relevant points. Animation The animation was made using Adobe Flash. This software is used for making websites and animations used for Internet adverts. It has the facility to export as a ‘flash video format’, which can then be played using a media player online. This software generates animation by allowing objects to be drawn on a stage and moved around using command lines and tools. This was used as it has the ability to animate objects and add audio narration. It also is designed for exporting animations to the Internet allowing the material to be accessed by a large number of people. Feedback A short questionnaire was generated which consisted of ten questions and placed online using a survey collection website (www.surveymonkey.com). Students were directed to the feedback questionnaire and allowed to submit this anonymously. Adapting the tutorial Some feedback constructively suggested changes that could be made. The video was updated after some concern about the speed of narration and that some of the narrative sections seemed to overlap. Analysis and Report The results of the feedback were then collected and displayed in a table. This was then added to the report and discussed with reference to research and previous project work. Results Students were allowed to access to the video animation through the Internet. After uploading the video an email was sent to students studying COMP2 at Bristol University. These students are required to know about aspects of stroke covered in this tutorial to pass this section of the course. The email notified them of the options to view the tutorial and how to give feedback. In total 30 students completed the feedback questionnaire and out of these 4 students provided optional written feedback. The results to the questions given were generally very positive. The majority of students showed a strong preference to video animations as a useful tool in medical education. The results are displayed in Table 1 below. TABLE 1 shows the ten question asked of the students and to what extent they agreed with each statement. Results are given in the percentage of students who chose the relevant category. Written Feedback Four written comments were made: "Really useful presentation!! Would be much better if someone proof read the whole thing as there are some spelling mistakes; also if the pauses between facts were longer it would be more easier to take in some facts. Overall, really nicely done!!" "Some of speech went too quickly, but good overall" "Very clearly written with excellent use of images to match the text and commentary!" "The Video was excellent." Discussion Student attitudes to this video tutorial were very positive. This was in contrast to the attitudes previously shown in the audio tutorial project (Buick, 2007) where video tutorials were not thought to be a useful resource. These results support recent developments in the generation of online video training for doctors by the Department of Health and previous research by Balsley et al (2005). Question one showed that the majority of students strongly agreed that the stroke video would be a useful resource. Questions two, three and four aimed to establish what aspects of a disease were best outlined using a video animation. Results showed that students agree or strongly agreed that defining the condition, pathophysiology and management were all well explained in this format. Interestingly, a large majority of students (70%) felt pathophysiology was best represented kinaesthetically. This may be due to the visual aspect that can be associated with pathophysiology. Disease processes are often represented using diagrams in textbooks with text explaining the disease process. Using computer technology it is possible to turn the text into audio narration and allow the user to view dynamic diagrams. In this way, students can better conceptualise the disease process, facilitating a more complete understanding of disease and its clinical manifestations. Question five aimed to highlight the benefit of visual stimulation as well as audio narration as a positive learning method. All students agreed or strongly agreed that the combination of these two aspects was beneficial. Question six showed a very strong response from students wanting access to more video tutorials, with 70% of students strongly agreeing to this statement. It is often the case that students take part in generating teaching material, and some students may be concerned that this material is inaccurate. However, many students do not think that this is a significant problem. This is reflected by the spread of student’s opinion seen in question 7, where there was no clear consensus of opinion. It may be that as students learn from a number of different resources, that any inaccuracies will be revealed and perhaps stimulate a better understanding through the process of verifying correct answers and practicing evidence based medicine. Question nine and ten show that most students value resources that allow sharing of educational material and feel they could help others learn. They would also value the option to feedback on this material. The written feedback showed positive responses from students. However there was feedback on some aspects of the video that they felt could be changed. The narration was delivered quickly with few gaps between statements to keep the tutorial short and concise, however this was thought to be distracting and made it less easy to follow. Following this feedback the narration was changed and placed back on the Internet for others to review. Further research and investigation could include the generation of a larger resource of video animations. My research has suggested that using animation to cover pathophysiology may be most beneficial. The software used to make this video also allows for the incorporation of interactive elements. The video produced in this project or other videos could have online menus, allowing users to select which part of the tutorial they wish to view rather than having to watch the whole animation, or they include interactive questions. Reflections Strength and weaknesses Strengths of this project include its unique approach to medical education. There have been few animated videos produced for undergraduate medical students that use this advanced software. This software is used by professional web developers but can be used effectively by students and doctors for educational purposes to produce video animation and interactive tutorials. For these reasons, I passionately believe that this technology could be used to revolutionise the way students learn medicine. If done effectively this could provide a more cost effective and engaging learning experience. This will ultimately benefit patients and doctors alike. This material can be place online allowing remote access. This is increasingly important for medical students studying on placements who are often learning away from the university setting. Weaknesses of this project include that of the work intensity of generating animated video. It is estimated that it takes around 6 to 9 hours to produce a minute of animated video. This does not include the research and recording of narration. The total sum of time to generate material and the additional skills needed to use the software makes generation of larger numbers of videos not possible by a small community of learners such as a university. Although it was done in this case, it is difficult to edit the material after it has been created. This may mean that material will become inaccurate when new advances occur. The feedback sample collected was opportunistic and the response rate was low. These factors may bias the results as only a subsection of opinions may have been obtained. These opinions may not be representative of the population studied or generalisable to them. It was difficult obtaining a professional medical opinion about the video in the time that I was allocated. However this has been organised for a later time. Knowledge and skills gained During this project I was able to learn about stroke its presentation, classification, management and risk factors. I read texts, which summarised stroke and research into risk factors and management of stroke. The challenge of usefully condensing a subject into a short educational tutorial was a challenging one. I feel I improved my skills of summarising information effectively. I gained knowledge of some of the challenges of undertaking a project such as this. One of the largest challenges included how long it took to produce the animation. In the future I will be aware of these difficulties and allow for time to gather information and generate the material. I also learnt the benefit of gaining feedback and allowing for adaption to this. It took more time to respond to feedback but this resulted in a better product that other students can use. I also reflected on the impact of stroke itself. Stroke has a major impact on patients, health care and carers. Much can be done in the recognition classification and management. A better understanding benefits all areas and I have gained a better knowledge and the importance of helping others gain a good understanding of stroke. I learned how to generate a video animation for the use of teaching in medicine and combine this with audio presentation. I learned how long it can take to generate material like this and the skill of organising my time effectively to manage a project. I can use this skill in the future to produce more educational material to help teach during my medical career. I also gained skills in learning how to place material on the Internet for others to access and will also use this in the future. Conclusions Previously evidence has shown the use of videos in medical education to be beneficial. It has normally been used to demonstrate clinical examination and procedures this study suggest there is a place for explanation of pathophysiology and disease summaries. However, there has been little research in to its use for graphically representing condition summaries. Computer technology now allows people to generate animation on their personal computer. It is possible that over time more students and doctors will start producing innovative visual and audio teaching material. This project indicates that this would be well received by students.

http://www.acadoodle.com Atrial fibrillation is the commonest cardiac arrhythmia encountered in clinical practice. In this condition, chaotic electrical impulses, generated from multiple sites within the atria and pulmonary veins, result in irregular depolarisation of the ventricles with a resulting irregularly irregular heartbeat. Recognition of atrial fibrillation on the ECG is a crucial skill as the arrhythmia increases the risk of stroke and heart failure. These complications are preventable with appropriate treatment. Atrial flutter is a common arrhythmia which arises by a very specific mechanism. This arrhythmia is easily missed on the ECG.

Medical blogging is blogging in the field of medicine. It is a relatively recent addition to the medical field. While its closest predecessor medical journalism; is about 300 years old, medical blogging is currently about a decade old. This blogpost aims at exploring the field of medical blogging and comparing it to related disciplines when relevant. It examines some opinions of bloggers, and reviews some medical blogs aiming to infer reasons for blogging, derive technique or outline of blog and hopefully arriving at a conclusion to the future prospects of medical blogging. Medicine is the practice of the art and science of healing 'ars medicina'. It is a branch of applied science, which started probably in the pre-historic era. The practice continued to flourish, specialise, sub-specialise and sub-sub-specialise. The word blog is most probably derived from the contraction of the words 'web log' which is a form of website that is more interactive, allowing comments, tagging,and is displayed in counter-chronological order from the most recent at the top of the page. The term 'blog' is currently used as a noun as well as a verb. The aggregation of blogs is named 'blogosphere', and the blog writer is named 'blogger'. There are single author blogs and multi-author blogs, they are as diverse in there content as the diversity of the bloggers, with regards to form they can be written text, images, videos, sounds or combination of more than one medium. The term 'blogroll' is referred to blogs followed by a person. Blogging is just more than a decade old now. However, the number of blogs have been increasing exponentially at times. The concept of blogging is considered as one of the components of the concept of web 2.0. Medical blogs refer to blogs that are primarily concerned with medical/health subjects. The name 'medical blog' is derived from content based taxonomic classification. Medical blogs can be classified by author, there are blogs by physicians, nurses, patients, medical institutions, medical journals, and anonymous blogs. They can be classified by target audience as either to other doctors, patients and carers, general public or a combination of more than one target. There are also medical blogs by patients or patient blogs that expresses their viewpoints. A study examined medical student blogs and concluded that they might be beneficial for students to reflect on their experience (Pinilla et al, 2013). The Nephrology Dialysis and Transplantation (NDT) made it own blog (El Nahas, 2012). The American Journal of Kidney Disorder (AJKD) made its own official blog (Desai et al, 2013). During the same year, the American Heart Association and American Stroke Association launched their official blog (Sanossian & Merino, 2013). Pereira discussed the blogs by neurosurgeons (Pereira et al, 2012). In the BMJ doc2doc blogs, they do not have to meet certain number of word count but will have to be reviewed prior to publication. KevinMD requires blog posts to be of maximum five hundred words, Medical-Reference require a minimum of one thousand words. Meducation requires a blog post to vary between 1500-3000 word. Independent blogs may show more variation in the number of words per blog post. Some blogs are predominantly in text format, other may combine multimedia or get linked to other medical blogs. The BMJ doc2doc tentatively recommends blog posting to be in the frequency of one to two blogs/month. Chrislyn Pepper, a medical blog writer, (2013) states that medical blogging can aim to be 'three blogs of 300+ words each week and three to four short blogs of less than a hundred words five days per week.' Medical bloggers seem to have various reasons to blog, some communicate clinical data to fellow doctors, in this case some blogs seem to resemble research or review articles in content and language which can contain medical jargon. There are diagnosis blogs that were studied by Miller and Pole (2010). The comparison between the electronic predecessors of blogging including Electronic Bulletin Board, USENET, and emailing in addition to the why of blogging in general has been discussed by Mongkolwat (Mongkolwat et al, 2005). Some put their hypotheses forward, others share clinical experience or discuss a clinical matter. Some bloggers direct their attention to the general public providing information about medical topics. Some discuss issues which can be difficult to be put in research topics. Dr Rob discussed that importance of medical blogging as an equivalent to the concept of democracy in an online world. Doctor Blogger website offers 10 reasons for medical blogging including public education, correction of misconceptions and establishing a name. For the medical blogger's direct benefit Medical Rant blog offers an overview of personal benefits from medical blogging including stimulation of thought and stimulation of academic writing. Dr Wible seems to use her medical blog to promote a standard of care that seems to be a mix between the medical model and the befriending model of care. Another study examined the young adults blogging and concluded that powerlessness, loneliness, alienation, and lack of connection with others, where the primary outcomes of young adults as a result of mental health concerns (Eysenbach et al, 2012). Wolinsky (2011) enquires whether scientists should stick to popularizing science or more. Medical blogs are essentially online activity which renders them immediately accessible to any area with internet connection, they are paperless by definition which makes them more environment friendly. The medical blogs are open access by default which adds to the accessibility, and they are decentralised which decreases control over the control and seems to accentuate diversity. As compared to peer reviewed journals, medical blogs seem to be less referenced, are hardly ever taken as academic writing, the process of peer reviewed medical blogs is minimal if any, and they do not get reflected on resume or be considered as publication, though the term 'blogfolio' started to become a watch word. It seems hard to base clinical decisions on medical blogs. However, medical blogs can offer more diversity into research and non-research medical topics. They are published online with no delay or review time, they can comment on the most recent advances in the medical field or most contemporary issues instantaneously. Very recently, citing blogs seems to become a bit accepted. BMJ Journals have their dedicated blogs Some online resources give a comprehensive outline on blogging in general and medical blogging in particular including video interview with a medical blogger Michelle Guilemard in her blog makes a valid point of how medical blogging can enhance career. Medical Squid also highlighted medical blogging as a career Kovic et al (2008) conducted a research on the medical blogosphere an concluded that 'Medical bloggers are highly educated and devoted blog writers, faithful to their sources and readers'. Miller & Pole (2010) concluded that 'Blogs are an integral part of this next stage in the development '. Stanwell-Smith (2013) discussed the aspect as an important tool to communicate with patients. The blur between academia and blogging was discussed in research blogs. (Sheema et al, 2012). During the same another study discussed the impact of blogging on research (Fausto et al, 2012). While Baerlocher & Detsky (2008) warn in an article against the hazards of medical blogging due to potential breach of confidentiality. After an exhaustive study of the content of weblog written by health professional, Lagu reached the concern of breaching of confidentiality (Lagu et al, 2007). Rebecca Golden (2007) cites the perils of medical blogging she concludes her article saying 'Science has a peer-review process for a reason'. Brendan Koerner (2007) in wired magazines posted an article about the problems of giving medical advice via blogging. Dr Val Jones makes a point by concluding that social media provide the 'allure of influence'. Thomas Robey (2008) offers arguments for and against medical blogging, including confidentiality, and ruining personal reputation on the negative side, while enhancing democratization of conversation and having a creative outlet on the positive side. Brendel offers an intriguing discussion to whether it would be ethical or not to monitor patients' blog to determine their health status. (Brendel, 2012). O'Reilly voiced in 2007 the need for blogging code of conduct. The GMC published guidance on the use of social media by doctors and it included blogging as a form of social media. The Royal College of General Practitioners also published the social media high way code to offer guidance on social media including medical blogging. There is also the medblog oath online. Flaherty (2013) argues that blogging is under attack by micro-blogging, and that it is in its deathbed. Mike Myatt in his article Is Blogging Dead, discusses various views about blogging in an era of micro-blogging The Royal College of Psychiatrists recently introduced a number of blogs including the president's blog, overseas blogs and other blogs. The medical blogging seems to occupy a middle space between the quick micro-blogging and the thoughtful research article. Its diversity and freedom are its strongest tools and can have the potential to be its worst enemies. One wonders whether the emergence of guidelines for medical blogging – given the seriousness of the content – would save medical blogging and elevate it to the next level or change the essence of it. After all, the question is how much the medical field which is a top-down hierarchy accept grass-root movement. Freedom of expression is probably at the heart of blogging. It would be logistically impossible to impose rules on it. However, guidelines and code of honour may help delineating the quality of medical blogs from each other.

In NeuroPsychiatry it might be difficult to locate its territory, and find its niche. This might be an uneasy endeavour as its two parent branches neurology and psychiatry are still viable, also it siblings organic psychiatry, behavioural neurology and biological psychiatry are also present. This blogpost attempts to search for the definition and domains of neuropsychiatry. Neuropsychiatry can be defined as the 'biologic face' of mental health (Royal Melbourne Hospital, Neuropsychiatry unit). It is the neurological aspects of psychiatry and the psychiatric aspects of neurology (Pacific Neurpsychiatry Institute). It is not a new term. Many physicians used to brand themselves as neuropsychiatrists at the rise of the twentieth century. It has been looked upon with a sense of unease as a hybrid branch. Also, it was subject to pejorative connotations, as the provenance of amateurs in both parent disciplines (Lishman, 1987). The foundational claim is that 'all' mental disorders are disorders of the brain' (Berrios and Marková, 2002). The American NeuroPsychiatric Association (ANPA) defines it as 'the integrated study of psychiatric and neurologic disorders' (ANPA, 2013). The overlap between neuropsychiatry and biological psychiatry was observed (Trimble and George, 2010) as the domain of enquiry of the first and the approach of the second will meet at point. Berrios and Marková seemed to have focused on the degree of conversion among biological psychiatry, organic psychiatry, neuropsychiatry and behavioural neurology. They stated that they share the same foundational claims (FCcs): (1) mental disorder is a disorder of the brain; (2) reasons are not good enough as causes of mental disorder; and (3) biological psychiatry and its congeners have the patrimony of scientific truth. They further elaborated that the difference is primarily due to difference in historic origins. (D'haenen et al., 2002). The American Neuropsychiatric Association (ANPA) defines neuropsychiatry as the integrative study of neurological and psychiatric disorders on a clinical level, on a theoretical level; ANPA defines it as the bridge between neuroscience and clinical practice. The interrelation between both specialities is adopted by The Royal Australia and New Zealand College of Psychiatrists as it defines it as a psychiatric subspeciality. This seems to resonate the concept that 'biologisation' of psychiatry is inevitable (Sachdev and Mohan, 2013). The definition according to Gale Encyclopedia encompasses the interface between the two disciplines (Fundukian and Wilson, 2008). In order to acknowledge the wide use of the term 'neuropsychiatry'; the fourth edition of Lishman's Organic Psychiatry, appeared and it was renamed as 'textbook of neuropsychiatry'. The editor stated that the term is not used in its more restrictive sense (David, 2009). Ostow backtracked the origin of biological causes for illness to humoral view of temperament.In the nineteenth century, the differentiation between both did not seem to be apparent. The schism seems to have emerged in the twentieth century. The difficulties that arose with such early adoption of neuronal basis to psychiatric disorders are that they were based on on unsubstantiated beliefs and wild logic rather than scientific substance. (Panksepp, 2004). Folstein stated that Freud and Charcot postulated psychological and social roots for abnormal behaviours, thus differentiating neurology from psychiatry. (David, 2009). The separation may have lead to alienation of doctors on both camps and helped in creating an arbitary division in their scope of knowledge and skills. The re-emergence of interest in neurospsychiatry has been described to be due to the growing sense of discomfort in the lack of acknowledgment of brain disorders when considering psychiatric symptoms (Arciniegas and Beresford, 2001). There is considerable blurring regarding defining the territory and the boundaries of neuropsychiatry. The Royal College of Psychiatrists founded section of Neuropsychiatry in 2008. The major working groups include epilepsy, sleep disorders, brain injury and complex neurodisability. In 1987 the British NeuroPsychiatry Association was established, to address the professional need for distinction, without adopting the concept of formal affiliation with parent disciplinary bodies as the Royal College of Psychiatrists. The ANPA was founded in 1988. It issued training guide for residents. The guide included neurological and psychiatric assessments, interpretation of EEG and brain imaging techniques. With regards to the territory, it included delirium, dementia, psychosis, mood and anxiety disorders due to general medical condition. Neurpsychiatric aspects of psychopharmacologic treatments, epilepsy, neuropsychiatric aspects of traumatic brain injury and stroke. The diagnosis of movement disorders, neurobehavioural disorders, demyelinating disease, intellectual and developmental disorders, as well as sleep disorders was also included. The World Federation of Societies of Biological Psychiatry (WFSBP) was established in Buenos Aires in 1974 to address the rising significance of biological psychiatry and to join local national societies together. The National Institute of Mental Health (NIMH), is currently working on a biologically-based diagnosis, that incorporates neural circuits, cells, molecules to behavioural changes. The diagnostic system - named 'Research Domain Criteria (RDoC) - is agnostic to current classification systems DSM-5 & ICD-10. Especially that the current diagnostic classficiations are mostly based on descriptive rather than neurobiological aetiological basis. (Insel et al., 2010). For example, the ICD-10 F-Code designates the first block to Organic illness, however, it seems to stop short of localisation of the cause of illness apart from the common prefix organic. It also addresses adverse drug events as tardive dyskinesia but stops short of describing it neural correlates. Also, psychosocial roots of mental illness seem to be apparent in aetiologically-based diagnoses as Post-Traumatic Stress Disorder, acute stress reaction, and adjustment disorders, the diagnostic cluster emphasise the necessity of having 'stress'. Other diagnoses seem to draw from the psychodynamic literature, e.g. conversion[dissociative] disorder. The need for neuropsychiatry, has been increasing as the advances in diagnostic imaging and laboratory investigations became more clinically relevant. Nowadays, there are tests as DaT-Scan that can tell the difference between neurocognitive disorder with Lewy Bodies and Parkinson's Disease. Vascular neurocognitive disorders warrant imaging as the rule rather than the exception, vascular depression has been addressed is a separate entity. Frontal Lobe Syndromes have been subdivided into orbitofrontal and dorsolateral (Moore,2008) Much training is needed to address this subspeciality. The early cases that may have stirred up the neurological roots of psychiatric disorders can be backdated to the case of Phineas Gage, and later, the case H.M. The eearlier fruits of adopting a neuropsychiatric perspective can be shown in the writings of Eliot Slater, as he attempted to search for the scientific underpinnings of psychiatry, and helped via seminal articles to highlight the organic aspect of psychiatry. Articles like 'The diagnosis of "Hysteria", where Slater, challenged the common wisdom of concepts like hysteria and conversion, rejecting the social roots of mental illness, and presenting a very strong case for the possibility of organicity, and actual cases of for which 'hysteria' was a plain misdiagnosis was way ahead of its time prior to CT Brain. Slater even challenged the mere existence of the concept of 'hysteria. (Slater, 1965) Within the same decade Alwyn Lishman published his textbook 'Organic Psychiatry' addressing the organic aspects of psychiatric disorders. Around the same time, the pioneers of social/psychological roots of mental illness became under attack. Hans Eysenck, published his book 'Decline and Fall of the Freudian Empire'. Eysenck stated clearly that the case of Anna O. seems to have been mispresented and that she never had 'hysteria' and recovered she actually had 'tuberculous meningitis' and she died of its complications (Eysenck, 1986). To summarise, it seems difficult and may be futile to sharply delineate neurpsychiatry, biological psychiatry, organic psychiatry and behavioural neurology. However, it seems important to learn about the biological psychiatry as an approach and practice neuropsychiatry as a subspeciality. The territory is yet unclear from gross organic lesions as stroke to the potential of encompassing entire psychiatry as the arbitary distinction between 'functional' and 'organic' fades away. Perhaps practice will help to shape the domain of the speciality, and imaging will guide it. To date, the number of post-graduate studies are still low in comparison to the need for such speciality, much more board certification may be needed as well as the currently emerging masters and doctoral degrees.

The case below is followed by a quiz question, allowing you a choice of diagnoses. Select the one letter section that best describes the patient’s condition. The Case A 28-year old woman has an unremarkable pregnancy through her first 28 weeks of gestation, with normal weight gain and no serious complications. She has no previous history of diabetes, hypertension of other systemic disease before or during her current pregnancy. During her 30-week checkup, her blood pressure measures 128/85, and she complains about feeling slightly more “bloated” than usual with swelling in her legs that seems to get more uncomfortable as the day goes on. Her obsterician recommends that she get more bed rest, stay off her feet as much as possible and return for evaluation in one week. At the one-week follow-up, the patient presents with noticable”puffiness” in her face, and a blood pressure of 145/95. She complains she has been developing headaches, sporadic blurred vision, right-sided discomfort and some shortness of breath. She has gained more than 10 lb (4.5kg) in the past week. A urinalysis on the patient revelas no glucose but a 3+ reading for protein. Her obstetrician decides to admit her immediately to a local tertiary care hospital for further evaluation. Over the next 24 hours, the patient’s urine output is recorded as 500mL and contains 6.8 grams of protein. Her plasma albumin level is 3.1 g/dl, hemacrit 48%, indirect bilirubin 1.5mg/dl and blood platelets=77000/uL, respectively. Her blood pressure is now 190/100. It is decided to try to deliver the foetus. The expelled placenta is small and shows signs of widespread ischmic damage. Within a week of delivery, the mother’s blood pressure returns to normal, and her oedema subsides. One month later, the mother shows no ill effects of thos later-term syndrome. Question What is the clinical diagnosis of this patient’s condition and its underlying pathophysiology? A. Gestational Hypertension B. Preeclampsia C. Gestational Diabetes D. Compression of the Inferior Vena Cava Answer The correct answer is "B. Preeclampsia". The patient’s symptoms and laboratory findings are consistent with a diagnosis of Preeclampsia, which is a condition occurring in some pregnancies that causes life-threatening organ and whole body regulatory malfunctions. The patient’s negative urine glucose is inconsistent with gestational diabetes. Gestational hypertension or vena caval compression cannot explain all of the patient findings. The patient has three major abnormal findings- generalised oedema, hypertension and proteinuria which are all common in preeclampsia. Although sequalae of a normal pregnancy can include water and salt retention, bloating, modest hypertension and leg swelling (secondary to capillary fluid loss from increased lower limb capillary hydrostatic pressure due to compression of the inferior vena cava by the growing foetus/uterus), oedema in the head and upper extremities, a rapid 10 pound weight gain and shortness of breath suggests a generalized and serious oedematous state. The patient did not have hypertension before or within 20 weeks gestation (primary hypertension) and did not develop hypertension after the 20th week of pregnancy with no other abnormal findings (gestational hypertension). Hypertension with proteinuria occurring beyond the 20th week of pregnancy however is a hallmark of preeclampsia. In addition, the patient has hemolysis (elevated bilirubin and LDH levels), elevated liver enzyme levels and thrombocytopenia. This is called the HELLP syndrome (HELLP = Hemolysis, Elevated Liver enzymes and Low Platelets.), and is considered evidence of serious patient deterioration in preeclampsia. A urine output of 500 ml in 24 hours is 1/2 to 1/4 of normal output in a hydrated female and indicates renal insufficiency. Protein should never be found in the urine and indicates loss of capillaries integrity in glomeruli which normally are not permeable to proteins. The patient has substantial 24 urine protein loss and hypoalbuminemia. However, generally plasma albumin levels must drop below 2.5 gm/dl to decrease plasma oncotic pressure enough to cause general oedema. The patient’s total urinary protein loss was insufficient in this regard. Capillary hyperpermeability occurs with preeclampsia and, along with hypertension, could facilitate capillary water efflux and generalized oedema. However myogenic constriction of pre-capillary arterioles could reduce the effect of high blood pressure on capillary water efflux. An early increase in hematocrit in this patient suggests hemoconcentration which could be caused by capillary fluid loss but the patient’s value of 48 is unremarkable and of little diagnostic value because increased hematocrit occurs in both preeclampsia and normal pregnancy. PGI2, PGE2 and NO, produced during normal pregnancy, cause vasorelaxation and luminal expansion of uterine arteries, which supports placental blood flow and development. Current theory suggests that over production of endothelin, thromboxane and oxygen radicals in preeclampsia antagonize vasorelaxation while stimulating platelet aggregation, microthrombi formation and endothelial destruction. These could cause oedema, hypertension, renal/hepatic deterioration and placental ischemia with release of vasotoxic factors. The patient’s right-sided pain is consistent with liver pathology (secondary to hepatic DIC or oedematous distention). Severe hypertension in preeclampsia can lead to maternal end organ damage, stroke, and death. Oedematous distension of the liver can cause hepatic rupture and internal hemorrhagic shock. Having this patient carry the baby to term markedly risks the life of the mother and is not considered current acceptable clinical practice. Delivery of the foetus and termination of the pregnancy is the only certain way to end preeclampsia.
