This article proposes a simplification to the chapter structure of current classifications of mental disorder, which cause unnecessary estimates of ‘comorbidity’ and pay major attention to symptom similarity as a criterion for deciding on groupings. A simpler system, taking account of recent developments in aetiology, is proposed. There is at present no simple solution to the problems posed by the structure of our classification, but the advantages as well as the shortcomings of changing our approach to diagnosis are discussed.

Patients with Huntington's disease can be a challenge to psychiatrists and to psychiatric services. We present a patient whose case history illustrates this and underlines the need for prompt and adequate treatment of psychiatric problems in this population. We discuss the psychiatric and behavioural manifestations of the illness, the treatments available and the role of psychiatric services in providing care for people with Huntington's disease.

This article describes the background to the introduction of supervised community treatment (SCT) in the 2007 amendments to the Mental Health Act 1983 for England and Wales. The evidence base for the use of SCT in the UK and in other countries to date is considered, and guidance from the literature regarding the decision to impose it is reviewed. Early local experience of SCT is described, in part through a number of fictitious vignettes. Finally, we present a set of guidelines which may be used by clinicians when considering SCT.

Issues pertaining to the medical treatment of children and young people can be both complex and emotive for all involved. At such times the courts may be asked to intervene and decide. Cases invariably need to consider issues of capacity to consent and treatment under best interests. Furthermore, such cases inevitably have human rights aspects. This article analyses the diverse role of the Human Rights Act 1998 in these cases and illustrates key underlying Human Rights Act principles that can be applied in clinical practice.

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.

Taking hostages has a long history as a method, with variable effectiveness, of securing concessions from individuals, organisations and governments. More recently, it has become a popular tactic among terrorist organisations. Although the resilience of individuals should never be underestimated, there is evidence that being taken hostage can have enduring effects, particularly on children. Individuals vary in how they cope with such an experience, both during and subsequent to it. The literature demonstrates that the research base is limited, and many important questions remain to be answered. Hostage-taking is an area of clinical and scientific interest. Apart from the need to establish the most effective post-incident interventions for individual hostages and their families, there are opportunities to develop further insights into the dynamics and effects of unequal power relationships.

We have arrived at our current descriptive classifications, with their many and varied array of categories, through the committee processes of DSM and ICD. To date, expert opinion, rather than solid science, has been the driver for change and this helps to explain the bewildering number of diagnostic categories and the fact that many patients meet criteria for several categories. Over the coming years, advances in neuroscience will offer the opportunity to base classification on robust evidence with diagnostic entities mapping more closely onto the workings of the brain. There are major shortcomings to the current classifications but all changes come at a cost to their users. We should be fully aware of the shortcomings and be thinking about the future. However, major changes to classification should await the emergence of robust empirical data and proven clinical utility. This will be the best way to benefit patients.

Aggression is common in older people with mental illness, with 15–43% of community referrals to old age psychiatry services and 44–65% of older people with Alzheimer's disease living in the community exhibiting such behaviour. In psychiatric in-patient units, assaults on staff are most common on wards for elderly people with organic mental illness. There is little high-quality research into the management of aggressive behaviour in dementia. We consider the available literature, which has shown certain behavioural measures and different classes of medication to be of benefit. We discuss factors associated with violence in elderly people with mental illness and potential management options.

Attention-deficit hyperactivity disorder (ADHD) is an established diagnosis in children but there is a lack of agreement about its validity as a distinct entity in adults. Literature suggests that between one-third and two-thirds of children diagnosed with ADHD continue to manifest symptoms into adulthood. An adult diagnosis should be done on the basis of a thorough assessment, structured and semi-structured clinical interview, and with a complete understanding of the symptoms that manifest in adults. This may be supplemented by the use of rating scales. We present a review of the literature covering aetiology, clinical presentations, diagnostic evaluation and management of ADHD in adults.

Very little attention has been paid to the invisible epidemic of substance misuse among older people in the UK. This article looks at the prevalence of substance misuse in the people over the age of 60. The reasons for difficulty in diagnosing substance misuse are explored and ways to improve diagnostic ability are discussed. Substance misuse leads to severe physical and psychiatric morbidity that is being managed by meagre resources. The article provides recommendations on specific issues related to interventions, biological and psychosocial, and training of psychiatrists.

The introduction of the supervised community treatment order (CTO) was a major and significant change to the Mental Health Act 1983 following the 2007 amendments to the Act. Owing to paternalistic aspects of psychiatry, such new legislation brings with it the potential to impinge on the human rights of patients. Any new legislation must be read and implemented to be compliant with the Human Rights Act 1998. Of all the articles comprising the Human Rights Act, Article 3 (the right to freedom from inhuman and degrading treatment), Article 5 (the right to liberty and security) and Article 8 (the right to respect for family and private life, home and correspondence) are of particular relevance to CTOs. We consider here the potential implications of the use of CTOs with regard to the Human Rights Act.

The Royal College of Psychiatrists' guidelines for the psychotherapy training of trainee psychiatrists include a supervised case experience in supportive psychotherapy. There is, however, a lack of clarity over the concept of supportive psychotherapy and how this might be taught and supervised, and this may discourage trainers from offering formal clinical supervision in this modality. In this article we briefly describe the history of supportive psychotherapy, the various ways in which it has been conceptualised, and some of the research in the area. We discuss the case for training and make practical suggestions for how this experience might be offered by consultant psychiatrists in an everyday psychiatric setting.

The humane treatment of prisoners has long been considered a mark of a civilised society. Early prison reformers such as Elizabeth Fry and John Howard campaigned vigorously for the improvement of conditions for inmates and for institutions to be focused as much on reform and rehabilitation as on punishment. This progressive improvement in conditions for those imprisoned has been further advanced by the European Convention on Human Rights and its incorporation into UK law. The Human Rights Act 1998 is playing an ever-increasing role in determining the standards of treatment of those detained by the state. Article 3 of the Act – freedom from torture and inhuman and degrading treatment – is of particular importance for those detained in prisons, hospitals and other institutions. As Article 3 case law has evolved, so its interpretation has broadened to include a thorough scrutiny of prison conditions, prison healthcare and the treatment of prisoners in general.

In this article we review the evidence base and practical experience supporting the use of psychopharmacological treatments for autism-spectrum disorders across the lifespan. Recent advances in knowledge are highlighted, as are the shortcomings of published data in this field. Psychosocial and educational interventions remain the core of treatment, but there is now evidence that medication management is a good option for certain domains of behaviour. We discuss the evidence in terms of symptom clusters, including the underlying social deficit of autism and common psychiatric comorbidities.

In recent decades there has been much interest in using cognitive–behavioural therapy (CBT) with children, young people and families. CBT is a collaborative approach, based on shared building of a hypothesis (the formulation) about causative and maintaining factors. When working with children, young people, their families and wider systems (e.g. a support network), therapy should incorporate interpersonal, family and systemic factors, together with developmental and attachment issues and phenomena more commonly expressed through other psychotherapeutic modalities. There is growing clinical experience that systemic cognitive–behavioural formulation can lead to systemic-process working on an individual, parent–child, family or wider-system basis. Formal evaluation of this approach is needed to consider where it fits among established psychotherapies in mental health work with young people and their families.

The United Nations' 1959 Declaration of the Rights of the Child states that ‘the child, by reason of his physical and mental immaturity, needs special safeguards and care, including appropriate legal protection, before as well as after birth’. In the UK, children and young people are afforded protection by two important pieces of legislation: the UN Convention on the Rights of the Child and the Human Rights Act 1998. There have been plentiful and varied challenges involving children and young people, in particular under Article 8 of the Human Rights Act. This review of Article 8 cases demonstrates both its use and key principles underpinning its use.

The deprivation of liberty safeguards were introduced into the Mental Capacity Act in 2008 to enhance the protection of adults in residential homes or hospitals who lack capacity in relation to their care arrangements and who are or may be deprived of their liberty. Deprivation of liberty itself is an imprecise concept and there may be difficulty in applying the appropriate authority where there is a choice between the Mental Capacity Act 2005 and the Mental Health Act 1983. Therefore, this article explains the evolution of mental capacity legislation and the concept of deprivation of liberty, how it may be recognised, prevented and authorised by deprivation of liberty safeguards, along with some of the interface issues with the Mental Health Act 1983.

A significant number of people who come into contact with the police have a mental disorder. Attending the police station to assess detainees forms a significant part of most psychiatrists' work. The role of the psychiatrist includes assessing for the presence of mental disorder, advising on diversion from custody and assessing detainees' fitness to be interviewed. This article, based on data primarily from the UK, looks at issues involved for psychiatrists attending police stations, including pathways to care, epidemiology, assessment of detainees under the Mental Health Act 1983, fitness of detainees to be interviewed and aspects of training.
