Adverse childhood events and self-harming behaviours among individuals in Ontario forensic system: the mediating role of psychopathy.

Background: Adverse childhood events (ACEs), psychopathy, and self-harming behaviours are prevalent among individuals in the forensic psychiatry system. While existing literature suggests that ACEs, self-harm, and psychopathy are interrelated, little is known about the interplay of psychopathic traits in this relationship. The present study aimed to determine the mediating role of psychopathy in the relationship between ACEs and self-harming behaviours in forensic patients.

Absconsion in forensic psychiatric services: a systematic review of literature.

While serious concerns are often raised when patients abscond or leave unauthorized from psychiatric services, there is limited knowledge about absconsion in forensic psychiatric services. Following the preferred reporting items for systematic reviews and meta-analyses guideline, we searched Medline/PubMed, PsycINFO, EMBASE, CINAHL, Scopus, and Web of Science through May 2020 for eligible reports on absconsion in forensic patients with no language limits. The search string combined terms for absconsion, forensic patients, and psychiatry in various permutations.

Electroretinography in psychiatry: A systematic literature review.

This review aims to consolidate the available information on use of electroretinography as a diagnostic tool in psychiatry. The electroretinogram (ERG) has been found to have diagnostic utility in cocaine withdrawal (reduced light-adapted b-wave response), major depressive disorder (reduced contrast gain in pattern ERG), and schizophrenia (reduced a- and b-wave amplitudes). This review examines these findings as well as the applicability of ERG to substance use disorder, Alzheimer's disease, autism spectrum disorder, panic disorder, eating disorders, attention deficit hyperactivity disorder, and medication use.

Incapacity of the Mind Secondary to Medication Misuse as a Not Criminally Responsible Defense.

The manifestations of disorders of the mind may play a role in the occurrence of criminal behavior. In the majority of the cases, the presence of a psychiatric disorder is cited as the reason that an individual was not fully aware of his behavior. However, other conditions, such as seizure disorders or hypoglycemia, have also been linked to an inability to understand the nature and consequences of one's actions.
