In this review of recent advances in the sub-specialty, we briefly discuss the current understanding of causes, presentations and evidence-based treatment of the most common disorders seen in clinical neuropsychiatry. Traumatic and acquired brain injury, epilepsy, multiple sclerosis, Parkinson's and Huntington's disease, sleep disorders and delirium are all considered, focusing on the most contentious issues and practical approaches to management and treatment.

Trainees need to gain experience in the psychotherapies, but practical problems in implementing training programmes have made it difficult for many trainees to access the full range of experience.

Bipolar disorder is a recurring, often chronic, illness characterised by periods of mania and depression with variable inter-episode recovery. For the majority of patients it is the depressive component of this illness that contributes to most of the associated morbidity, social disability and mortality. Research and clinical experience suggest that acute treatment and prevention of depressive episodes is by far the most challenging aspect of the care of patients with the disorder. This review examines the contribution of depression to the course and outcome of bipolar disorder as well as diagnostic difficulties that often complicate treatment and may lead to inappropriate medication. Key studies that form the evidence base of treatment recommendation for bipolar depression are presented and areas of therapeutic uncertainty are highlighted.

Issues relating to the consent of individuals under 18 years of age in England and Wales are covered by the Family Law Reform Act 1969, the Children Act 1989, the Mental Health Act 1983 (to some extent) and case law. Legislation on the consent of minors to hospital admission and treatment is complicated and contradictory, leaving clinicians unsure when to rely on the consent of the minor or that of someone with parental responsibility. This article reviews the concept of the zone of parental control (ZPC), introduced in England in 2008. It argues that this concept is too vague and subjective to provide any clear guidance on who can give consent for a minor's admission and treatment.

In making treatment decisions, psychiatrists, like other medical professionals, must adhere to rules of ethical medical conduct. They may also need to negotiate the legalities associated with detention and treatment against a patient's wishes. The growth in guidance produced by organisations such as the National Institute for Health and Clinical Excellence has added further complexity. Practitioners are increasingly required to consider cost-effectiveness in their treatment decisions and this can appear to conflict with the principles of medical ethics. With particular reference to mental healthcare, this article attempts to answer two questions: Is economic evaluation unethical? And are the methods of economic evaluation unsound for the purpose of achieving an ethical distribution of resources?

Charcoal-burning has become a common method of attempted suicide in Asia and survivors are often intoxicated with carbon monoxide (CO). Reports of the neuropsychiatric aspects of CO poisoning date back to 1914. This article outlines the neuropsychiatric sequelae that have been described secondary to CO poisoning. The underlying pathophysiology and management strategies, including acute management and cognitive rehabilitation, are discussed as these topics are of relevance to psychiatrists.

Religious laws do not usually forbid the use of psychotropic medication, but many do forbid the consumption of animal-based derivatives of bovine and/or porcine origin (e.g. gelatin and stearic acid) such as are found in many medications. Demonstrating awareness of this, combined with a genuine concern about how it affects the patient, may strengthen the doctor—patient relationship and avoid non-adherence. In this article, we outline dietary requirements of key religions and belief systems that may have a bearing when prescribing medication containing animal-based ingredients. We identify common psychotropics that contain animal-based derivatives and suggest alternative prescribing options and approaches to dealing with sensitive ethical issues.

The purpose of this first article of four addressing the electronic approaches to psychotherapy (e-therapy) is to introduce the equipment (computers) and systems (the World Wide Web and the internet) involved. I describe some of their many elements (e.g. bits and bytes), uses (such as search engines, email, web mail) and a few abuses (e.g. spam, spyware).

The adjective ‘comorbid’, and its fellow noun ‘comorbidity’, are used repeatedly in psychiatric practice, but we frequently use them sloppily and ignore what they really mean. Here, I briefly define comorbidity of disorders, and suggest the alternative categories of consanguinity and co-occurrence.

Frantz Fanon (1925–1961), a West Indian of mixed race, was a French colonial psychiatrist trained in Lyon, France, who worked mainly in colonial North Africa between 1953 and 1957. He was one of the earliest psychiatrists to suggest that the lived experience of ethnic minorities within a discriminatory colonial environment could trigger mental illness. This article focuses on Fanon's work and contributions to psychiatry, as well as his philosophy, advocacy for social inclusion and pioneering work in culturally relevant rehabilitation. It also examines what lessons could be learnt from his life's work as a psychiatrist and traces his influence on a generation of psychiatric researchers, suggesting how his contribution may have influenced critical thought and current views.

Enhancing a patient's adherence to psychotropic medication regimens is one of the challenges facing all mental health professionals. Medication is part of an overall care package that often depends on patients' engagement with the clinician or service. The therapeutic alliance might be improved by more active listening to patients. A reduced capacity may limit a patient's ability to make a treatment choice. This can be improved by provision of more time and information. If these techniques are insufficient, closer monitoring may be achieved by working with relatives and carers, or more frequent visiting. Strategies to avoid covert non-adherence could include checking for picked up prescriptions and the use of depot preparations. Finally, the use of compulsory powers may be appropriate, with attention to preserving or rebuilding the therapeutic alliance.

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.

This article discusses the importance of residence capacity – an individual's mental capacity to decide where they should live – and suggests how it should be assessed. People with dementia or intellectual disabilities, as well as those with other mental disorders, are sometimes required to make this decision. Assessments of capacity must be conducted with considerable care, given the implications for the individual and for their human rights. The assessment must be objective and functional: the assessor must be able specifically to demonstrate a lack of decision-making ability. Yet assessments of capacity still require evaluative decisions to be made. We suggest some basic information that should be conveyed to the person faced by the prospect of a change of residence where there is a doubt about capacity.

This article considers sexuality in older adults and the associated stereotypes and stigmas that lead to this area being underappreciated. Normal physiological changes in ageing are discussed and how they can cause sexual dysfunction. The elderly population has a higher burden of comorbid physical illness and this review considers evidence on the interplay between physical health and sexual health. Mental illness is also strongly linked with sexual functioning and is discussed, as is the evidence on psychotropics and sexual side-effects. Attitudes on sexuality in long-term care settings are highlighted and approaches to managing sexual disinhibition are included.

In many ways cognitive and behavioural therapies represent the acceptable face of psychotherapy for the general psychiatrist. They are brief, focused, problem-oriented treatments, which take symptoms seriously. They show an affinity for the medical model in their acceptance of diagnostic categories and their commitment to effective evaluation of treatments through randomised controlled trials. The wide applicability of these therapies is also attractive to the general psychiatrist. Cognitive and behavioural techniques are of major importance in the treatment of anxiety disorders, depression, eating disorders, and sexual dysfunctions, and beyond this core group the methods can be applied to enhance coping and change unwanted behaviours in conditions as diverse as cancer, chronic pain, substance abuse, anger control, schizophrenia, and challenging behaviours in people with learning disabilities.

Challenging behaviours often co-occur at high rates among those with autism spectrum disorder and intellectual disability. Challenging behaviours, including self-injury, aggression and property destruction, can be associated with social impairment and increased caregiver demands and stress. These behaviours often arise from and are maintained by a combination of biological and environmental risk factors throughout the lifespan. Given the impact of challenging behaviours on development, function-based assessment and intervention approaches are crucial. The prevalence, risk factors, assessment tools and evidence-based treatment options utilised for individuals with developmental disorders are discussed.

The psychiatric sequelae of trauma have been most often discussed in relation to disasters, both natural and man-made, and military conflict. This may sometimes lead psychiatrists to think of posttraumatic stress disorder (PTSD) and other posttraumatic mental illnesses as being somewhat exotic and unusual in general psychiatric practice. In this paper, I propose that PTSD and related disorders are actually common psychiatric problems which require treatment.
