Despite the lack of supportive scientific evidence, the uptake of community treatment orders (CTOs) in England and Wales since their introduction in late 2008 has been higher than expected, although there has been a relative dearth of second opinion appointed doctors. In Scotland, CTOs now constitute about 30% of all long-term civil detentions, with lack of insight and lack of treatment adherence given as the major reasons for CTO use. Ethical considerations such as balancing autonomy against health needs will continue to be weighed by clinicians considering compulsory treatment in the community.

The concept of positive and negative symptoms in schizophrenia can be traced back to Hughlings Jackson (1889) who taught that disease does not create, it sets free, and accordingly positive symptoms could be seen as ‘release’ phenomena resulting from ‘dissolution’ of the highest cerebral centres of the nervous system. Crow (1980) revived the dichotomy and proposed a Type I syndrome, characterised by positive symptoms, and a Type II syndrome, characterised by negative symptoms. He thought the latter was due to cortical atrophy and responded poorly to antipsychotic medication. In their review of the distinction, Walker & Lewine (1988) found a stronger relationship between premorbid dysfunction and negative symptoms than with positive symptoms. They also found there was a stronger influence of genetic factors on negative symptoms than positive symptoms.

This paper addresses how mental illness and psychiatry are presented in autobiographical narratives. The richness of clinical psychopathology unmediated by the expectations of psychiatry is described. The rituals of psychiatry, the importance of the personal relationships between patients and clinicians, and the subjective beliefs of people about mental illness are explored.

The substantial strain that women are facing during the COVID-19 pandemic can affect their menstrual cycle and further impair their quality of life. In low- and middle-income countries, this strain is exacerbated by: cultural taboos and poor education related to menstruation; ‘period poverty’; unavailability of menstrual hygiene products; and poor hygiene facilities. We suggest actions that governments, healthcare professionals and individuals can take to address these factors and minimise the psychological impact of COVID-19 on women's physical and mental health.

That Zwi & York (2004) have opened the discussion on adult attention-deficit hyperactivity disorder (ADHD) is to be applauded. Their main conclusion is that the diagnostic validity of adult ADHD remains uncertain and that further study is needed. This is based on a review of the ADHD concept in childhood and the longitudinal studies that have followed children with ADHD into adulthood.

In this second part of a two-article review on malingering we consider the challenges of presenting clinical and psychometric findings. Numerous clinical and demographic factors are statistically associated with malingering but applying them to an individual case risks challenges to the expert psychiatric witness's evidence. Although psychometric data can usefully help strengthen or challenge a diagnosis, expert witnesses must recognise and report the limitations of these tests. We recommend that psychiatric expert witnesses do not try to look for or to link any external incentives with clinical findings, and indeed we suggest that they should, other than exceptionally, avoid using the term ‘malingering’. It is the job of the court, not the expert witness, to ascertain an individual's credibility and motives. We suggest a framework for presenting expert psychiatric evidence in this area.

This article deals with the provisions for the lawful detention and compulsory treatment of patients in England and Wales. The 2007 amendments to the Mental Health Act 1983 redefine ‘mental disorder’ and ‘medical treatment’ and remove the classifications required for longer-term detention, abolishing the so-called ‘treatability test’ and introducing a new appropriate-treatment test. ‘Learning disability’ is brought within the definition of mental disorder but only if ‘associated with abnormally aggressive or seriously irresponsible conduct’. The exclusion for promiscuity, other immoral conduct or sexual deviancy is repealed; the exclusion for dependence on alcohol and drugs is retained. The revised definition of ‘medical treatment’ includes psychological treatment and removes the requirement that treatment is under medical supervision. The basic structure of the 1983 Act is retained. Use of the powers is discretionary. The principles of the Mental Capacity Act 2005 are imported into the decision-making framework through the wording of the Mental Health Act Code of Practice.

Video technology was first used in psychiatric services in the 1950s but came into general use in the 1990s, particularly in North America and Australia. Video has utility across all ages and in a wide range of clinical situations. These include case conferencing for patients with complex problems (e.g. when planning discharge from specialist inpatient units), psychological assessment and treatment, Mental Health Act assessments, suicide risk assessment and work in forensic settings. Potential for benefit may be most obvious in remote locations, but video use is also relevant in urban settings. Lack of training and experience, inadequate access to equipment and insufficient technical support have all limited the take-up of this technology in the UK. This article briefly reviews the literature and outlines technical and cost considerations when using video technology. Three services in Scotland are described to illustrate ways in which videoconferencing can enhance services.

Depression and anxiety are common in adolescents, but most affected will not get any formal help. Digital mental health technologies (i.e. resources and interventions to support and improve mental health) are a potential way to extend the reach and increase adolescents’ access to therapies, at a relatively low cost. Many young people can access the internet and mobile technologies, including in low- and middle-income countries. There has been increased interest in integrating technologies in a range of settings, especially because of the effect of the COVID-19 pandemic on adolescent mental health, at a time when services are under pressure. This clinical review gives an overview of digital technologies to support the prevention and management of depression and anxiety in adolescence. The technologies are presented in relation to their technological approaches, underlying psychological or other theories, setting, development, evaluations to date and how they might be accessed. There is also a discussion of the potential benefits, challenges and future developments in this field.

Economic evaluation involves the comparative analysis of the costs and consequences of alternative (different) treatment options. Economic evaluations provide decision makers with information about the relative value for money, or cost-effectiveness, of various treatment programmes. The relative cost-effectiveness of new interventions is a key consideration in health technology assessments by the UK's National Institute for Health and Care Excellence, and economic evaluations alongside randomised controlled trials are routinely requested by funders such as the National Institute for Health Research. This article outlines some of the key concepts and issues in the economic evaluation of mental healthcare.

Autism is a pervasive and life-long disorder that is characterised by profound deficits in communication and social understanding, together with ritualistic and obsessional behaviours and a general resistance to change. Although usually associated with additional cognitive impairments (approximately 50% of those affected have an IQ below 50) the condition can occur in individuals of all levels of ability, and around 20% of cases have an IQ within the normal range. Estimates of prevalence vary from 3.3 to 16.0 per 10 000 and rates may be even higher if children within the autistic wider spectrum are included (Wing, 1993, 1996). Understanding of causation is still limited, although genetic factors are now known to play a major role (Lord & Rutter, 1994).

Physical symptoms with no medical explanation are commonly experienced by healthy people and those attending clinics. Psychiatrists see such patients in liaison settings and clinics for those with psychotic and affective disorders. The pathophysiology remains obscure; physical investigations are usually performed to exclude pathology rather than elucidate dysfunction. However, modern neuroimaging has allowed the study of nervous system structure and function. Although there are few diagnostically specific findings, patterns of association have emerged: where action is impeded (certain forms of conversion disorder and chronic fatigue syndrome) frontal systems of the brain are often implicated; when subjective awareness of the body is disturbed (passivity phenomena and anorexia nervosa) temporo-parietal cortices appear to be dysfunctional. The caudate nuclei (components of the frontal executive circuit) are implicated in a variety of syndromes (including body dysmorphic disorder, somatisation and chronic fatigue). The brain may be viewed as a cognitive neurobiological entity, crucially oriented towards action (for survival). Psychiatric syndromes that have an impact on bodily awareness signal dysfunction within systems representing that body and its performance in time and space.

Assessment is key to the educational process and plays a significant role in looking at the progress trainees make as a result of training and personal development. Recent developments in curricula have led to substantial changes in assessing progress and attainment throughout postgraduate medical education in the UK. This article outlines the framework used to develop the postgraduate curriculum in psychiatry and describes the nature and purpose of the assessment programme that forms part of this new curriculum. The article considers the principles of medical education that are essential for the success of assessments, not only centrally in the development of the assessment system, but also locally in the delivery of these assessments. The overall context of developments in medical education, as well as the relationship between workplace-based assessments (WPBAs) and formal examinations, are described with specific references to developments in psychiatric training, its curriculum and assessments.

Much of the drug testing available today is able to determine the presence or absence of a variety of psychoactive substances in a range of body fluids and tissues. For the results of such tests to be confidently interpreted, additional information is required, including general assessment and history-taking. In a wide range of large psychiatric surveys, substance dependence emerges as one of the most common mental health-related disorders, and it is also the one that is least likely to be treated. The range of available tests can be best considered as acting to support and complement a broader assessment and diagnostic procedure.

Despite the enormous amount of literature on medical care of older people, personality disorders in late life have been given little attention. Clinicians tend not to assign this diagnosis to older adults in view of limited research into, and therefore limited awareness of, this topic. This article aims to promote better understanding of this subject in view of the growing population of older people and hence an expected increase in the number of personality disorder cases.

The phenomenon of acute behavioural disturbance (ABD) (also known as acute behavioural disorder or excited delirium) is an underrecognised and potentially life-threatening syndrome, and an emergency in psychiatric settings. Causes are discussed and the pathophysiology explained. The challenges faced by practitioners are highlighted, including how ‘standard’ control and restraint can exacerbate symptoms. Initial treatment strategies are suggested.

This guide to the neurological disorder cerebral autosomal dominant arteriopathy with subcortical infarcts and leuco encephalopathy (CADASIL) is specifically targeted at psychiatrists. The aims are to enhance awareness, provide educational clinical information and offer practical guidance on management of the disorder. An overview of diagnostic algorithms and recent research is also provided.
