Suicide is one of the major causes of death in young people, in whom suicide can occur in clusters. In this Review, we have investigated definitions and epidemiology of such clusters, the factors associated with them, mechanisms by which they occur, and means of intervening and preventing them. Clustering of suicidal behaviour is more common in young people (<25 years) than adults. Suicide clusters can occur as a greater number of episodes than expected at a specific location, including in institutions (eg, schools, universities, psychiatric units, and youth offender units). 

Background: It is generally recommended to exercise caution in applying trauma-focused treatment to individuals with posttraumatic stress disorder (PTSD) and comorbid borderline personality disorder (BPD).

Objective: To investigate the effects of a brief, intensive, direct trauma-focused treatment programme for individuals with PTSD on BPD symptom severity.

Background: There is substantial comorbidity between trauma-related disorders (TRDs), dissociative disorders (DDs) and personality disorders (PDs), especially in patients who report childhood trauma and emotional neglect. However, little is known about the course of these comorbid disorders, despite the fact that this could be of great clinical importance in guiding treatment.

Posttraumatic stress disorder (PTSD) brings with it diagnostic symptoms that can be debilitating and persist for years. Left untreated, PTSD can have far‐reaching and damaging consequences for the individual, families, communities, and society at large. Although early detection and intervention are recognized as key to the effective treatment of PTSD, many individuals who suffer from PTSD do not seek essential health services. The aim of the present study was to identify the barriers and facilitators to help‐seeking for individuals with PTSD, based on existing literature.
