When admitting patients to hospital and treating them, psychiatrists and other health professionals may need to deprive them of their liberty. Where this occurs, professionals will need to work within a statutory framework to practice legally and protect their patients’ right to liberty under Article 5 of the European Convention on Human Rights. Within England and Wales, some clinical scenarios will require a choice to be made between the Mental Health Act 1983 (MHA) and the Mental Capacity Act 2005 (MCA) and its Deprivation of Liberty Safeguards (DoLS). This choice can be complex, is often overlooked and frequently misunderstood in clinical practice. Deciding between the two frameworks must be done on a case-specific basis. With the use of code of practice guidelines, case law and an unfolding clinical scenario we aim in this article to support clinicians in taking a clear-sighted approach to the dilemma and the factors to consider when deciding between the two regimes.

E-mental health tools are a promising solution to reducing the high prevalence of perinatal mood and anxiety disorders and addressing barriers faced by women seeking professional help. This article summarises the main e-health tools used in perinatal mental healthcare, including examples of evidence-based tools for assessment, prevention and treatment of such disorders. We also highlight the main characteristics of the development process of e-mental health tools, which are based on cognitive–behavioural therapy, as well as the ethical concerns to be considered with their use and integration in healthcare systems.

Post-traumatic stress disorder (PTSD) is a complex, heterogeneous mental health problem that can be challenging to identify, assess, understand, diagnose and treat. This article provides an overview and critique of key topics, literature and principles to inform comprehensive and meticulous assessment of PTSDs. Although expert witnesses are the target audience, this article will have relevance for identifying, assessing, understanding and diagnosing PTSDs in all clinical contexts. A range of topics relevant to assessment are discussed, including: the complex relationship between trauma and PTSDs; DSM-5-TR PTSD and ICD-11 PTSD and complex PTSD diagnoses and the similarities and differences between them; the clinical presentation of PTSDs; psychological models of PTSDs; how to approach assessment and differential diagnosis; the impact of PTSD on neuropsychological abilities and functioning (disability); causation, reliability and assessing PTSDs when this is being considered as a legal defence; evidence-based interventions (medication, psychological therapy, when is the ‘right time’ for therapy, contraindications); and prognosis (if untreated, how long therapy/change takes). Given ongoing debate, the article proposes that trauma exposure is best defined in future iterations of the DSM and ICD as exposure to one or more psychologically threatening or horrific experiences that are overwhelming.

Complex post-traumatic stress disorder (CPTSD) was adopted as a new diagnosis in ICD-11. Trauma-focused cognitive–behavioural therapy (CBT) is effective in treating PTSD but with CPTSD being a recently defined diagnosis, the evidence for its effectiveness in that disorder is not as clear, but it is still promising. This article reviews the diagnosis, psychopathology and some key differential diagnoses, and looks at the two CBT approaches that are currently used in clinical practice: the phase-oriented approach and the unimodal approach. The key aims of this article are to clarify the concept of CPTSD, its differentiation from borderline personality disorder and prominent comorbidities, how it develops and how CBT is used to treat it.

The Parole Board for England and Wales advises on the release, recall and licence conditions of a small subgroup of prisoners serving determinate sentences and the majority of those serving indeterminate sentences. Since the establishment of the Parole Board in 1968, the parole process has been shaped and clarified by further legislation and case law. In certain scenarios, psychiatric expert evidence may be sought to inform the Board's determination of whether a prisoner can be safely released into the community. Psychiatrists preparing expert reports for the Parole Board should be familiar with the current operationalisation of parole. This involves an understanding not only of the functioning of the Parole Board, but also of the criminal justice context in which prisoners subject to parole are managed. Having set the scene, by describing the role of the Parole Board and the wider context, this article examines how to undertake assessments and complete psychiatric reports for the Board.

This article critically reviews the case law, guidance and standards related to the provision of expert psychiatric evidence in immigration and asylum cases in the UK. It discusses the potentially complex and medico-legally challenging process of psychiatric evaluation of asylum seekers, and the implications of the presence of psychiatric disorders for issues such as the individual's ability to give oral evidence in court, immigration detention, fitness to fly, removal, deportation, ability to reintegrate into the destination country and appeal rights. To give context to the discussion, it outlines the asylum process in the UK from claiming asylum, initial screening and the ‘substantive interview’ to, if a claim is rejected, appeal to the First-tier Tribunal (Immigration and Asylum Chamber), detention and the removal process.

To make a valid will, a person should be able to understand the nature and consequences of doing so, the extent of their estate and the claims others may have on it. No disorder of mind should be present that would affect their testamentary decisions, and clinicians are therefore often asked to give an opinion on whether a person has testamentary capacity. This article discusses the legal issues involved, with reference to UK case law (in particular, the legal test of Banks v Goodfellow (1870)), and outlines the requirements of testamentary capacity assessment (including retrospective assessments), the clinician's responsibilities when requested by a solicitor to make an assessment of capacity (‘the golden rule’) and what they might expect if appearing in court to give expert witness regarding testamentary capacity. Fictitious case studies are presented illustrating certain points in testamentary capacity assessment.

Clinical guidelines recommend avoiding the use of medications to manage personality disorder. In clinical practice, however, substantial amounts of medication are used. In this article, we summarise the recommendations of guidelines published in various countries in the past 15 years. We review the evidence from randomised controlled trials and recent reviews, discuss the discordance between guidance and clinical practice and give recommendations on what a clinician should consider if they choose to prescribe in cases of severe disturbances in mood or behaviour despite the lack of evidence.

The large volume of seemingly conflicting guidance on the management of borderline personality disorder (BPD), combined with the ongoing shortage of specialised resources, can make the task feel like an exclusive undertaking that the general psychiatrist is underprepared for. In this article, we distil current evidence to submit that sound psychiatric management principles used to treat all serious and enduring mental disorders (diagnostics, comorbidity management, rational pharmacotherapy and dynamic risk management) are readily applicable and particularly therapeutic for BPD. We offer actionable practice guidance that we hope will render the clinical management experience a more lucid and rewarding one for both practitioner and patient.

The article reviews some basic statistical concepts used in medicine, including the mean, standard deviation, sensitivity and specificity. Using this background the authors describe how these can be applied to cognitive tests, taking the Montreal Cognitive Assessment (MoCA) as an example. Two different approaches to using the MoCA in diagnosing dementia are considered: one using a fixed cut-off score, the other taking account of normative data about the effects of age and educational level on MoCA scores. It is recommended that clinicians assessing cognitive function should not rely on a fixed cut-off score, but where possible compare the patient's result with those of people of comparable age and educational background, although normative data of this kind are not always available.

This article reviews some of the various shorter cognitive tests that are available. They vary in complexity, time taken to administer them and what specific neurocognitive domains they assess. They range from screening tests such as the Mini-Cog to more detailed measures such as the Montreal Cognitive Assessment or the Mini-Mental State Examination. The Addenbrooke's Cognitive Examination is more comprehensive and covers attention, memory, verbal fluency, language and visuo-spatial function. The article suggests areas of cognition that may be related to the six competencies assessed in the determination of fitness to plead and to stand trial.

The history of the Grange Annual Conference is traced to its roots in the work of Sir William Norwood East, the Royal Medico-Psychological Association and Waddiloves Hospital in Bradford, UK.

The Royal College of Psychiatrists’ report CR193 details the responsibilities of psychiatrists who provide expert evidence to courts and tribunals. This brief commentary describes the rewards and challenges of expert witness work, the author's role as the College's Lead for Expert Witnesses, and importance of CR193 for expert psychiatric witnesses.

This is areview of an early and important textbook published by Sir William Norwood East.

John Thomas Perceval (1803–1876) was confined first to Dr Fox's private madhouse (asylum) in 1830 and transferred to Mr Newington's madhouse at Ticehurst, Sussex, in 1832 until his release in 1834. His account of his incarceration and treatment was published in two versions, the first in 1838 and the second in 1840. In this article I describe Perceval's psychosis, his treatment and management at Dr Fox's madhouse and his reforming and advocating contributions to psychiatry in the period following his release.

This article considers the role of experts and their interaction with the legal system to better understand the benefits and potential dangers of expert evidence to fact-finders in trials. Medical experts are indispensable to the administration of justice as litigation ranges beyond what judges or juries comfortably deal with as facts of everyday life. This would render courts, absent expert evidence, vastly under-equipped in making decisions of fact. However, the dangers of surrendering authority to experts or of misunderstanding their role must be considered to ensure that expert evidence is used to benefit the administration of justice.

Many authors have considered the ethical dilemmas of a doctor being both the treating physician and expert witness in litigation. The debate has often focused on the potential for bias and the adverse impact being an expert witness can have on the therapeutic alliance. Much of this debate seems rooted in the ethic of non-maleficence. In this article we attempt to examine the other end of this ethical quandary. Using a pragmatic approach, we explore these conflicts and consider biases from other sources. Ultimately, taking on the mantle of both roles is becoming increasingly unavoidable. Hence we argue that, although there are challenges, embracing this dual role can be an important part of holistic treatment, risk management and the pursuit of the ethical principle of justice.

The Bell Jar (1963) is a semi-autobiographical novel written by the confessional poet, novelist and short-story writer Sylvia Plath (1932–1963). It has been often cited as a recommended reading within the medical humanities, because of its powerful description of depression and the understanding-by-experience of the related psychiatric treatments. This brief article, primarily directed at the clinically oriented reader, presents a selection of excerpts from The Bell Jar to illustrate the main diagnostic features of clinical depression and the vital role of therapeutic relationship quality in hindering or facilitating treatment outcomes and recovery.

This article reviews the seminal work of Jaak Panksepp: Affective Neuroscience: The Foundations of Human and Animal Emotions. It outlines the basis of his theory of Basic Emotional Command Systems as common to all mammals and goes on to specify some of the key fields that have grown out of his research.

Essays on Partial Derangement of the Mind in Supposed Connection with Religion, written amidst the illness of its author almost two centuries ago, was the little-known work of a distinguished physician. Seeking to rebut the argument that religion is causative of ‘derangement of the mind’ it takes a surprisingly biological view of such conditions while, at the same time, affirming the importance of faith, hope and love in human well-being. Despite its limitations, it makes observations that remain relevant to debates about religion and psychiatry today.
