Metabolic dysfunction has been long associated with severe mental illness (SMI), often viewed as a comorbidity to be managed. However, emerging evidence suggests that metabolic dysfunction, particularly at the mitochondrial level, may be a foundational element in the pathophysiology of neuropsychiatric disorders. This commentary expands on the current understanding by exploring the brain energy theory of mental illness, which posits that mitochondrial dysfunction is central to both metabolic and psychiatric conditions. The roles of insulin resistance, chronic stress and environmental factors are highlighted as shared biopsychosocial determinants that contribute to deterioration in both metabolic and mental health. The therapeutic potential of the ketogenic diet is discussed, particularly its ability to improve mitochondrial function and alleviate psychiatric symptoms. This shift in perspective, from viewing metabolic dysfunction as a secondary concern to recognising it as a root cause of SMI, has significant implications for clinical practice and research. By focusing on bioenergetic deficits and mitochondrial health, psychiatry may advance towards more effective, integrated treatment approaches that target the underlying cellular dysfunctions driving both metabolic and mental illnesses.

Although fundamental advances in the life sciences raise the exciting possibility of novel translational therapies, optimal evidence-based usage of established treatments should be the bedrock of current clinical care. The authors argue that there are instances where well-established treatments are ‘underused’ in psychiatry; electroconvulsive therapy, clozapine and lithium are exemplars of this. This article explores possible reasons for, and strategies to address, this underuse.

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.

Natoli et al present a comprehensive higher level framework aligning dimensional personality pathology assessment with treatment delivery through a hierarchical model. Their approach integrates common therapeutic factors with trait-specific interventions, offering a promising pathway for clinical implementation. Despite strong evidence supporting the superiority of dimensional models and the field's shift towards dimensional classification, they remain largely unused in clinical practice after a decade, despite evidence of clinical utility and learnability. Although the authors’ framework demonstrates how dimensional approaches could work in practice, particularly through matching severity to treatment intensity and traits to specific interventions, healthcare systems require evidence of improved clinical outcomes before undertaking systemic change. Without controlled trials demonstrating enhanced treatment effectiveness, dimensional models risk remaining theoretically superior but practically unused. While healthcare systems remain tethered to categorical diagnostic approaches, the authors’ framework offers a practical pathway for implementing dimensional models – one that now requires testing in real-world settings.

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.

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 Mental Health Act assessment or interview is a commonplace process in psychiatric services during which significant decisions are made about a person’s care and liberty. Individuals have reported negative experiences of being subjected to these assessments, at times even influencing their ongoing relationship with healthcare and recovery. A 2018 independent review of the Mental Health Act 1983 (MHA) for England and Wales identified numerous areas for practice improvement, including the identification of epistemic injustice as part of current MHA processes. Nevertheless, the assessment process has received little attention on how it is conducted, with scant clinical guidance, training or research available on the subject. In this article the authors propose seven principles that assessors can incorporate into interviews to improve the way in which the MHA assessment is conducted. These principles have been drawn from a dialogical and relational approach to psychiatric care called Open Dialogue. A dialogical approach to MHA assessment could improve experiences of being assessed, information gathered, and, by preserving therapeutic relationships, give better longer-term outcomes.

Although most people experiencing psychosis are not violent, a diagnosis of a psychotic disorder is associated with an increased likelihood of violence. Some progress has been made in delineating the nature of this association, but it remains unclear whether specific types of psychotic experience make a specific contribution to the propensity for violence. Just as the phenomenological approach has produced a fuller understanding of psychotic experiences (that can inform improved aetiological and interventional frameworks), the authors assert that such an approach (with its closer attention to the full extent of the patient's subjectivity) has the potential to advance our understanding of the relationship between psychosis and violent behaviour in a way that has clinical applicability. This article examines this potential by overlaying approaches to the phenomenology of psychosis with a framework for the subjectivity of violence to demonstrate how a fuller explanatory formulation for violent behaviour can be derived.

Until recently, statistical consultants did not have to worry about being replaced by artificial intelligence. There was no statistical analogue to ‘Dr Google’ before ChatGPT arrived on the scene. Although ChatGPT (most of the time) adequately responds to basic queries such as the assumptions of different statistical tests or summarises relevant manuals on statistical software providing clear instructions with point-and-click software such as SPSS, there are many important aspects of statistical consulting that ChatGPT does not cover. This tutorial article is about these aspects: a summary of what statistical consulting is, its purpose and possible settings during the empirical research cycle, the role and responsibilities of the consultant and the client, how to ensure a good consulting experience, how to prepare for a consulting session, typical questions and more. The article was written for researchers who are considering contacting a statistician for the first time and aims to facilitate a good and fruitful consulting experience for all parties involved.

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.

Navigating the complex relationship between violence and psychosis can frequently be challenging. Psychiatrists may find assessing and managing the risk of violence in this context daunting. In their article on the topic, Anderson et al helpfully summarise the role that psychopathology can play in this process. However, although careful elucidation of an individual's experiences may assist in the nuanced formulation of their risk and could offer a specific focus for interventions, the approach has potential shortcomings in certain settings. For some phenomena the link with violence is unclear and it may be constellations of symptoms that are important. Causal pathways are not always linear and there may be important mediators linking psychopathological features to behavioural outcomes. In the resource-limited settings in which many contemporary health services operate, a detailed assessment of psychopathology may be hampered by time or other constraints. Alternative, more scalable solutions may therefore be needed in particular scenarios.

This article examines the complex phenomenon of self-harm, exploring its motivations, theoretical underpinnings and the intricate transference and countertransference reactions that arise in clinical settings. It aims to integrate psychiatric understanding with contemporary theories of the impact of trauma on both the body and the mind, to deepen the knowledge of self-harm and increase the effectiveness of treatment approaches. The article argues for a nuanced view of self-harm and emphasises the need for compassionate, well-informed care. By addressing the psychodynamics of self-harm, the article seeks to improve therapeutic outcomes and foster an empathetic and effective clinical response. Fictitious case studies are used to illustrate these concepts, demonstrating the critical role of early attachment experiences and the challenges faced by healthcare providers in management.

Qualitative research methods, defined as the collection and analysis of non-numerical data to understand concepts and experiences, are often used to inform mental health practice and policies. When utilising qualitative research methods, it is important that the researcher uses an explicit theoretical framework to guide the study. A theoretical framework informs how researchers engage with a topic or problem, report on their work with participants, describe key concepts and address assumptions within the research questions and procedures. In this article, we describe the basic concepts underpinning three of the most commonly used frameworks in mental health research: positivism, interpretivism and critical realism. We also describe how these theoretical frameworks may guide the qualitative process, including the theoretical and methodological approaches chosen and the ways in which these theoretical frameworks can be applied in practice. To enhance understanding of these frameworks, we include examples of how such frameworks can be used in qualitative mental health research.

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.

Despite being the most prevalent personality disorder, borderline personality disorder remains a diagnosis with many unanswered questions, particularly concerning pharmacological management. Although many clinical practice guidelines suggest not prescribing medication unless there are significant clinical comorbidities, it is one of the psychiatric diagnoses with the highest rates of polypharmacy. This commentary on a BJPsych Advances article aims to raise clinical questions regarding the voids of knowledge and the appropriateness of medicating and, perhaps, overmedicating in this particular group.

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.

This article discusses the importance of personal recovery in psychiatry and proposes a new socially constitutive process. The author, an expert by experience, emphasises that recovery is not only an individual endeavour but also an intersubjective one. Moreover, social relationships and external factors such as community, family, health service culture and social norms influence the recovery process. The socially constitutive process posits that support from professionals and family members is crucial, significantly reducing the burden of responsibility carried by individuals with mental illness.

This article responds to Wells & Giacco’s discussion of the theoretical frameworks that guide qualitative research. In addition to the methods they explore, I describe ethnography, focusing on the anthropological investigation of culture. I use examples from the research literature to highlight the unique values of ethnography. I describe what ethnography entails, before outlining illustrations of how ethnographic research has contributed to psychiatric clinical practice. Although it is difficult to generalise from the findings of ethnographic research, its focus on how social processes work and how people perceive them in a particular context makes it useful for advancing improvements in clinical care.

Personality disorders can worsen with age or emerge after a relatively dormant phase in earlier life when roles and relationships ensured that maladaptive personality traits were contained. They can also be first diagnosed in late life, if personality traits become maladaptive as the person reacts to losses, transitions and stresses of old age. Despite studies focusing on late-life personality disorders in recent years, the amount of research on their identification and treatment remains deficient. This article endeavours to provide an understanding of how personality disorders present in old age and how they can be best managed. It is also hoped that this article will stimulate further research into this relatively new field in old age psychiatry. An awareness of late-life personality disorders is desperately needed in view of the risky and challenging behaviours they can give rise to. With rapidly growing numbers of older adults in the population, the absolute number of people with a personality disorder in older adulthood is expected to rise.

Clozapine is the only evidence-based intervention for treatment-resistant schizophrenia. One of the drug's most well-known and potentially fatal adverse effects is agranulocytosis (severe neutropenia). Hence, regular blood tests are an essential component of clozapine treatment. This article presents a narrative review of the history, incidence, potential aetiology and management of clozapine-associated neutropenia. It gives an overview of clozapine monitoring requirements, including those for benign ethnic neutropenia. We point to the growing body of evidence that the risk of clozapine-induced agranulocytosis is mostly confined to the first year of treatment and that the risk of fatality is considerably lower than previously assumed. Given the absence of alternative evidence-based interventions for treatment-resistant schizophrenia, we suggest that rechallenging with clozapine should be considered in most patients with clozapine-associated mild to moderate neutropenia who do not respond to other treatments. A more careful risk–benefit analysis is needed in cases of severe neutropenia (agranulocytosis).
