There is a debate about long-term treatment of schizophrenia with antipsychotic drugs, with some experts suggesting that these drugs should be discontinued. In this issue, Takeuchi et al demonstrated by a meta-analysis of 11 trials that antipsychotic drugs maintained their efficacy for relapse prevention for 1 year, whereas patients on placebo kept getting worse. We consider these findings in the light of the current discussion about possible dose-related brain volume loss, supersensitivity psychosis, the high variability of results in long-term follow-up studies and recent approaches to discontinue antipsychotics in patients with a first-episode. The new findings speak in favour of continuing antipsychotics at the same dose, at least in patients whose condition is chronic, but the topic is complex.

Recent data might subtly recalibrate the risk/benefit ratio of lithium, the prototypical mood stabiliser for bipolar disorder. There are hints that lithium might be associated with a reduction in dementia risk and as noted in this Journal, a surprising reduction in the risk of cancer.

Negative public attitudes towards psychiatry hinder individuals coming for treatment and prevent us from attracting and retaining the very brightest and best doctors. As psychiatrists we are skilled in using science to change the thoughts and behaviours of individuals, however, we lack the skills to engage entire populations. Expertise in this field is the preserve of branding, advertising and marketing professionals. Techniques from these fields can be used to rebrand psychiatry at a variety of levels from national recruitment drives to individual clinical interactions between psychiatrists and their patients.

There is now a good body of evidence about factors that determine outcome and recovery in a first episode of psychosis. However, so far, this is of limited benefit when making predictions at an individual level. Treatment protocols are one size fits all and the recommended duration of medication remains unclear. What is needed is a more sophisticated approach to predicting outcomes and tailoring treatment options to the individual. Removing predisposing factors is an important aspect of this.

The DSM and ICD have taken steps to introduce a grief disorder as a new diagnostic entity. Evidence justifies the inclusion of prolonged grief disorder, but not complicated grief, as a new mental disorder.

Precision medicine in psychiatry is on the rise, and depression and obesity – two highly prevalent, comorbid and well-characterised phenotypes – are optimal targets for the approach. Add the bedrock susceptibility gene, FTO, and Riviera et al have identified a constellation of factors that could enhance clinical treatment of both disorders.

Lesbian, gay, and bisexual (LGB) young people have been found to be at greater risk of suicidal behaviour. National prevention strategies have identified the need to reduce suicide risk in this population. However, research on specific risk factors for LGB young people that might inform suicide prevention programmes are at an early stage of development.

Anxiety and affective symptoms are prominent features of schizophrenia which are often present in the prodromal phase of the illness and preceding psychotic relapses. A number of studies suggest that genetic risk for the disorder may be associated with increased anxiety long before the onset of psychotic symptoms. Targeting anxiety symptoms may represent an important strategy for primary and secondary prevention in schizophrenia.

Because lithium is now recommended as the initial long-term treatment for bipolar disorder in general and has a lower teratogenic potential than originally reported, it may become more frequently prescribed in childbearing women. The article by Wesseloo et al in this issue provides helpful data and guidance for managing lithium dosing in the perinatal period.

Befriending allows for control of the non-specific factors of the therapist–patient interaction in psychosocial research. Manualised befriending is at the very least an active placebo and potentially an effective intervention. Befriending now merits increased research attention to determine indications for use and to elucidate mechanisms of action.

Suicide, a common cause of death in many low- and middle-income countries, has often been viewed through a medical/psychiatric lens. Such perspectives medicalise social and personal distress and suggest individual and medication-based treatments. This editorial argues for the need to examine suicide from a public health perspective and suggests the need for population-based social and economic interventions.
