Less-common personality disorders affecting patients admitted to in-patient units are discussed in some detail. These disorders are rarely a direct cause of admission, but they are often associated with other Axis I disorders and can therefore be obstacles to successful treatment. A knowledge of the clinical picture and underlying dynamics and an awareness of countertransference feelings that these patients are likely to provoke can enhance therapeutic alliances and improve the chance of effective care plans.

Attention-deficit hyperactivity disorder (ADHD) is a commonly diagnosed childhood psychiatric disorder. Debate over its diagnostic validity, aetiology, presentation and treatment has extended from the clinical to the public domain. As children with ADHD diagnoses reach adulthood there is increasing interest in ‘adult ADHD’. Cohorts followed up show poorer outcomes as adults than do controls. Self-referred adults, sometimes relatives of children with ADHD, are also of interest regarding adult ADHD. Innovative work is being done examining issues of aetiology, treatment, outcomes and comorbidity in these groups, but heterogeneity among those diagnosed with ADHD and changes in classification systems and diagnostic criteria over time complicate comparison of research findings. The diagnostic validity of adult ADHD remains uncertain and needs further study.

Mental health services are not yet organised to allow patients with personality disorders easy access, and practitioners lack the necessary skills to implement effective treatment. A number of service models have developed, albeit without a clear evidence-base. These include sole-practitioner, divided-functions and specialist-team models. In general, a divided-functions or specialist-team model is probably best for reducing risk and improving outcomes. Both models present difficulties with integrating treatment, but these can be overcome by good communication. Good management of patients requires careful assessment of need and risk, a consistent approach, constancy of staff, team coherence and adequate in-patient support. Not all practitioners can treat patients with personality disorders and the interpersonal skills of the mental health professional may be crucial in maintaining a patient in treatment.

Randomised controlled trials and surveys of patients' experiences indicate that the recognition and prompt treatment of early warning signs of relapse in selected patients with bipolar affective disorder are effective in lengthening the time to the next manic relapse and improving function. Improvements in patient coping mechanisms allied to these techniques can prevent some depressive episodes. The intervention is described in some detail and conditions under which it is most likely to be effective or to fail are reviewed. If the intervention is to be successful, patients must be carefully selected, early warning signs and symptoms must be analysed in detail, it must be a central feature of the care plan and the service must be ready to respond quickly to a patient's early warning symptoms.

The risk of suicide is higher during the period immediately following discharge from in-patient psychiatric care than at any other time in a service user's life. Demographic and clinical risk factors for suicide in this period are similar to those for suicide at other times and may not be specific enough to enable identification of those at greatest risk. Epidemiological studies suggest that factors related to service organisation and delivery (e.g. social support and continuity of care) are also important in the aetiology of suicide following hospital discharge. Interventions aimed at helping people in the period immediately following discharge from in-patient care have been developed. Although the effect of these interventions on suicidal behaviour has not been examined, available evidence suggests that efforts to increase patients' confidence and level of social support may be of value.

Asperger syndrome, a form of autism with normal ability and normal syntactical speech, is associated with a variety of comorbid psychiatric disorders. The disorder is well known to child psychiatry, and we are beginning to recognise the extent of its impact in adulthood. The article reviews the diagnosis and assessment of Asperger syndrome and its links with a wide range of psychiatric issues, including mental disorder, offending and mental capacity. It also describes the broader, non-psychiatric management of Asperger syndrome itself, which includes social and occupational support and education, before touching on the implications the disorder has for our services.

The authors describe the main forms of supported accommodation available to people with mental health problems in the UK. They address the questions of who needs supported accommodation and how people may be selected for the differing types of unit. Historical trends and policy in this area are reviewed and the general research evidence and evidence of cost-effectiveness are considered. A ‘total system’ approach to assessing accommodation need in a locality is advocated. The authors also consider key quality issues that should be addressed for supported accommodation to be effective.

Most child and adolescent mental health services recognise the existence of, and need for treatment in, attention-deficit hyperactivity disorder (ADHD). Many specialist multidisciplinary ADHD clinics have been developed in recent years, and many paediatricians have included the treatment of ADHD as an important part of their clinical activity. A good deal of the justification for this increase in therapeutic activity has been the demonstration that ADHD is indeed a predictor of adult mental health problems. General adult psychiatry, however, has not followed suit in identifying and treating substantial numbers of affected people. It is likely none the less that an increasing load in adult psychiatry will develop. A rising number of young people will enter adult life still receiving stimulant medication or other treatment for ADHD, and adult psychiatrists are likely to be consulted. Furthermore, an increasing number of adults are likely to recognise themselves as having been disabled by ADHD and therefore to seek assistance. In many cases, individuals with adult ADHD who require specific treatment for the condition will have been treated unsuccessfully for disorders with overlapping symptom profiles such as anxiety, depression, bipolar disorder and antisocial personality disorder.

People who survive into late life with chronic or relapsing illnesses, which had their onset in youth or middle age, have special needs. In the past, those most severely affected often lived out their lives in mental hospitals. The mental hospital closure programme led to discharges to alternative care, and the successes and failures of these have been monitored by some services. Subsequent generations are at risk of falling between the care of general psychiatry, rehabilitation psychiatry and old age psychiatry. These patients are uniquely disabled by a combination of personal, social, mental and physical health disadvantage. The Royal College of Psychiatrists has produced guidance to highlight the special needs of these ‘graduates', encouraging every locality to investigate its own performance in their care and bring it into line with best practice in the light of local strengths and resources.

Research evidence has shown that morbidity and mortality rates are higher in psychiatric patients than in the general population. This article describes factors that affect the physical health of psychiatric patients living in institutions and the steps that can be taken to review, monitor and improve their physical health. The physical health care of long-stay patients should reach the same standards as those expected in the general population.

All people with learning disabilities should be able to choose from a variety of residential placements as a way of achieving greater community integration. However, many are still placed away from their borough of origin, resulting in complex consequences for them, and their families and for clinicians. This article explores the nature of the problem, defining the current issues, and examining the role of the stakeholders and the implications for psychiatrists working in this field.

Advance statements, originally designed for situations of terminal illness, are becoming increasingly relevant in psychiatry. This article examines their background, rationale and use in old age psychiatry. The difference between advance statements and advance directives is highlighted, and different roles are suggested for each. We discuss the advantages, and the possible limitations, of advance statements, including the unique issue of the Mental Health Act 1983.

The motor vehicle on the road has a history of only just over 100 years. It is a major form of personal and public transport, but is also associated with hazards and risks. Many more people are killed on the roads each year in Britain than are the victims of homicide. General and forensic pyschiatric evaluation of offenders charged with or convicted of motoring offences is, however, infrequent, despite the presence of mental health problems in some of them. I describe psychiatric, criminological and legal factors associated with driving of motor vehicles, as many psychiatric patients have driving licences and have access to a vehicle or, indeed, may decide to drive unlicensed.

The authors review contemporary indications for neurosurgical interventions in the management of chronic and refractory mental disorder, the procedures involved, their efficacy and known adverse effects. These data are presented within the context of a brief historical overview of the use of neurosurgery for mental disorder. In addition to a consideration of neurosurgical procedures that rely on the creation of putative therapeutic lesions, we also review two novel, non-destructive neurosurgical electrostimulation treatments that may represent viable alternatives to conventional ablative neurosurgery: vagus nerve stimulation and deep brain stimulation.

Recent developments in UK government policy have highlighted the unmet needs of people with dual diagnosis (comorbidity of substance misuse and psychiatric disorder, particularly severe mental illness). Advances in assessment techniques and diagnostic practice have informed the treatment of comorbidity and improved its outcome. There is growing evidence for the effectiveness of psychosocial interventions such as motivational interviewing and cognitive–behavioural therapy, mostly from US studies. However, within the secondary care provided by addiction and general psychiatric services there are serious implementation barriers related to service organisation, staffing levels, training and – most importantly – the difficulties of engaging people with severe mental illness and comorbid substance misuse in treatment. The evidence for the effectiveness of psychosocial treatments and models of service is reviewed and challenges for optimal practice in the UK are highlighted.

The emphasis on the evidence base of treatments may diminish awareness that critical appraisal of research into other aspects of psychiatric practice is equally important. There is a risk that diagnostic tests may be inappropriate in some clinical settings or the results of a particular test may be over-interpreted, leading to incorrect diagnosis. This article outlines the method of critically evaluating the validity of articles about diagnostic and screening tests in psychiatry and discusses concepts of sensitivity, specificity and predictive values. The use of likelihood ratios in improving clinical certainty that a disease is present or absent is examined.

The care programme approach (CPA) should be implemented across all mental health services. However, the specific needs of psychotherapeutic settings were not recognised in the official documentation. The scope for conflict between therapeutic practices and CPA requirements may have increased following revision of CPA guidelines. A recent survey of consultants in psychotherapy confirmed that implementation of CPA remained uneven. The additional time required, threats to confidentiality and a negative impact on the therapeutic relationship were common concerns. Positive effects on assessment procedures and liaison between services were also reported. Practical suggestions for minimising potential negative effects of CPA are given. It is recommended that all services providing psychological therapies develop a written policy for the local implementation of CPA.

Risk assessment is notoriously difficult and offers a particular challenge to mental health workers. There are two main conceptual approaches to the consideration of risk assessment and management: the actuarial and the clinical methods. I use case material to examine the clinical, and in particular the psychodynamic, approach in order to illustrate that violent behaviour has meaning. Understanding its meaning and learning from it can substantially reduce the risks of further violent behaviour. Managing risk with the aid of psychodynamic psychotherapy enables the patient to become aware of his or her own mind and its function. Although this process may initially be distressing to the patient, in the longer term the aim is to enable the development of a healthier, more stable internal reality. This should, in turn, reduce the risk of dangerous acting out.

People with learning disabilities suffer an increase in common morbidity, communication difficulties, a high prevalence of serious conditions such as epilepsy, and specific patterns of health needs associated with the aetiology of their disability. Unfortunately, this combination of need is mirrored by a consistent picture of poor health promotion uptake, inadequate care for serious morbidity, unrecognised health need and poor access to health care. Consequently, there is a great disparity between the health of learning-disabled people and that of the general population. Psychiatrists can address this disparity in clinical practice by focusing on these patients' mental health, epilepsy management and the impact of behaviour on health. They can also influence health planning and service development.
