The purposes of classification, that is, the putting of apparently related items into categories (boxes) is to simplify large amounts of complicated information, and improve communication. In Chapter 1, mention was made of the two main systems of classification of mental disorders (DSM and ICD). These systems arrange lists of mental disorders under a number of major headings (22 in the case of DSM5 and 9 in the case of ICD-10). DSM5 and ICD-10 have acceptable reliability, but do not guide treatment. In the future, we may perhaps make diagnoses using objective means such as genetics and neuroimaging. Others have emphasised the importance of a method of diagnosis based on etiology. McHugh (2005) describes an etiological diagnostic system of 4 clusters: 1) “brain disease”, in which there is disruption of neural underpinnings (e. In this chapter a simplified classification system is presented. The mental disorders have been arranged under the following headings: “psychotic”, “mood”, “non-psychotic”, “personality” and “organic mental disorders”. A related classification is “substance use disorders”. There has been debate as to whether substance use disorders are social or behavioural problems, or mental disorders. Currently they are included as mental disorders in DSM5 and ICD-10. However, in many jurisdictions, services are provided by separate, specialized treatment teams.

A simplified classification system Intoxication and psychosis Withdrawal The current method of diagnosing and classifying mental disorders is problematic, being largely based on clinical impressions. When tests are used, it is usually to rule out Gambling Disorder conditions which are not mental disorders, for example, a brain scan will exclude the possibility of brain tumour. The main data the psychiatrist has is the appearance and behaviour of the patient and the words he or she uses to describe thoughts, feelings and other experiences. They are all in current use and this can cause misunderstandings. One meaning is senseless folly – as when the two young, unsuited, incompatible people have a wild love affair. Such undue enthusiasm appeared in the newspaper headline: “US Mad About Harry Potter”. Another meaning has to do with anger, as when the fathers of the young people mentioned above discover the affair, splutter, cancel credit cards and talk of rewriting wills etc. A bumper sticker used the angry meaning: “Cigarette companies – the truth will make you mad!

The NHS is increasingly focussing on prevention and on the early detection and treatment of potentially progressive disease, whilst the prevalence of risk factors for CKD, such as diabetes, obesity and hypertension is rising. It is therefore a great pleasure to introduce this timely new guideline on CKD from the National Collaborating Centre for Chronic Conditions (NCC-CC) and the National Institute for Health and Clinical Excellence (NICE). The recommendations you will read here are the result of a thorough review of the published research. The field of renal medicine has a complex evidence base, and enormous thanks are due to the Guideline Development Group for their hard work and attention to detail, and to the NCC-CC Technical Team who worked enthusiastically alongside them. Readers involved in research in this field, and those who want to find the full rationale behind a particular recommendation, will find this an invaluable resource. The Department of Health, in commissioning this guideline, was clear that the focus was to be on early detection and management. This is the area in which the guideline can deliver its greatest potential benefit, through delaying progression of disease and thus reducing the need for dialysis or transplantation. The key priority recommendations singled out in the guideline reflect this emphasis. They present clear criteria for testing for CKD, suspecting progressive CKD, and referring people for specialist assessment, all of which should be useful in primary care. Recommendations are also provided on starting treatment once proteinuria has been assessed. In common with other guideline topics in chronic conditions, there are some areas in CKD which remain in need of good quality research to inform difficult clinical decisions. The GDG have not shirked from addressing these questions and their expertise informed debates which led to some forward-thinking recommendations, for example those dealing with testing for proteinuria. For many practitioners a change in practice will be required as a result, but great effort has been taken to explain the rationale for this change within the guideline, and to demonstrate that the necessary effort is worthwhile. As healthcare professionals in primary care take on an increasing role in the management of CKD, it is hoped that this guideline will be a single useful and accessible reference promoting a consistent high quality of care and hence improved quality of life for longer for people with CKD.

ACE inhibitors are used for blood pressure control and congestive heart failure. Adverse events A harmful, and usually relatively rare, event arising from treatment. Algorithm A flow chart of the clinical decision pathway described in the (in guidelines) guideline. Allocation concealment The process used to prevent advance knowledge of group assignment in an RCT. Bias The effect that the results of a study are not an accurate reflection of any trends in the wider population. This may result from flaws in the design of a study or in the analysis of results. Blinding (masking) A feature of study design to keep the participants, researchers and outcome assessors unaware of the interventions which have been allocated. Carer (care giver) Someone other than a health professional who is involved in caring for a person with a medical condition, such as a relative or spouse. Case-control study Comparative observational study in which the investigator selects individuals who have experienced an event (for example, developed a disease) and others who have not (controls), and then collects data to determine previous exposure to a possible cause. Clinical audit A quality improvement process that seeks to improve patient care and outcomes through systematic review of care against explicit criteria and the implementation of change. Clinician In this guideline, the term clinician means any health care professional. Available electronically as part of the Cochrane Library. Cohort study A retrospective or prospective follow-up study. Groups of individuals to be followed up are defined on the basis of presence or absence of exposure to a suspected risk factor or intervention. A cohort study can be comparative, in which case two or more groups are selected on the basis of differences in their exposure to the agent of interest. The interval is calculated from sample data, and generally straddles the sample estimate. The 95% confidence value means that if the study, and the method used to calculate the interval, is repeated many times, then 95% of the calculated intervals will actually contain the true value for the whole population. Cost-effectiveness An economics study design in which consequences of different analysis interventions are measured using a single outcome, usually in natural units (for example, life-years gained, deaths avoided, heart attacks avoided, cases detected). Alternative interventions are then compared in terms of cost per unit of effectiveness. Cost-effectiveness model An explicit mathematical framework, which is used to represent clinical decision problems and incorporate evidence from a variety of sources in order to estimate the costs and health outcomes.

After some general conversation cheap 120 mg isoptin visa, the examiner may say something like safe 120 mg isoptin, “Thank you Mr X, I understand what you have been saying. When a patient who has been treated respectfully but makes excuses or refuses cognitive testing, there is probably cognitive impairment. Where memory function is the primary problem the patient may not be able to remember why he/she is present. The patient should be able to give details of who made the arrangements for the interview, how she/he was conveyed from home or work, at what time did he/she depart home or work, at what time did he/she arrive and how long the journey took. Thus, the history gives the opportunity for a real life test of the recent memory. Internal consistency of the personal history, however, may give important information. That is, do the dates, ages and events match up, when patient describes her/his past life. The names and current ages of children and siblings are often useful questions. An alarm goes off if a 70 year old appears to have little idea of the age of her/his children. Short-term (immediate) memory test The most common test is to ask the patient to repeat sequences of digits. Three digits are given first and the patient is asked to repeat them. A healthy person of average intelligence is usually able to repeat seven digits correctly. The patient is advised that she/he will be given some words to remember, and that later in the interview she/he will be asked to recall them. The patient is asked to repeat each word after it has been said, to ensure that each has been registered properly. The interview then proceeds so that the patient is distracted. Some minutes later the patient is asked to recall the words. If any words cannot be recalled, the test can be re-administered using a different set of words. The score is kept, “the patient remembered two out of four items”. Individual differences in intelligence and education make it difficult to know what questions on past world events are reasonable to ask. The date of birth is often available to the examiner. However, this is very highly learned material, it is among the last pieces of information to be lost and its retention does not exclude moderately severe memory problems. It is reasonable to ask the capital cities of Australia, England and USA, and perhaps the dates of the first and second world wars - taking care to consider intelligence and education levels. It is reasonable to ask the name of the current Prime Minister or President. Often patients with memory problems give the name of a Prime Minister or President from the past – in this case, in clinical experience, the more remote in time the named person held office, the greater the memory problems. Loss of memory/Amnesia - clinical pictures Loss of memory of organic origin Dementia Dementia (see Chapter 20) is a global deterioration in intellectual functioning, a central feature of which is memory problems. It is usually of gradual onset, although it may follow sudden events such as head injury. In general, the more recently stored the more rapidly lost; memories stored long ago are lost last. However, this is a relative matter and the remote memory of patients with dementia is usually significantly impaired compared to that of non-demented persons or comparable age. Patients frequently lack insight and deny difficulties. Confabulation (untrue experiences which the patient believes) may occur in the early stages but this curious sign usually declines over time. The impression is that the ideas flood in to fill a memory vacuum. Head injury, cerebral neoplasm, carbon monoxide poisoning and herpes simplex encephalitis are other causes. Loss of memory of psychological origin Psychogenic amnesia In psychogenic amnesia the predominant disturbance is an episode of sudden inability to recall important personal information, which is not due to an organic mental disorder. The clinical presentation is compounded by the combination of unconscious forgetting and active avoidance of painful material. The memories lost and the understanding of the patient of their condition usually varies with time and circumstances. Unlike organic amnesia, the ability to learn new material is usually retained. Insofar as disorientated people are frequently given orienting information by other individuals, but remain disorientated, the condition has a memory component.
