The use of transcranial direct current stimulation (tDCS) to reduce impulsivity and aggression in adults with mild intellectual developmental disabilities: the tDCS-RIADD randomised controlled trial protocol.

BACKGROUND: Challenging behaviours, in particular aggressive behaviours, are prevalent among people with intellectual developmental disabilities. Predictors of challenging behaviours are numerous, including past history of aggression, poor coping skills and impulsivity. Factors like motor or rapid-response impulsivity (RRI) have neurobiological underpinnings that may be amenable to change via neuromodulation using non-invasive brain stimulation techniques like transcranial direct current stimulation (tDCS). METHODS: This study aims to determine the efficacy of anodal tDCS in reducing RRI and incidents of aggression in people with intellectual developmental disabilities (IDD) in residential or hospital settings. Using a single blind, randomised, sham-controlled trial design, adults with IDD, with a history of impulsivity leading to aggression, will be randomised to receive either repetitive anodal or sham tDCS applied to the left dorsolateral prefrontal cortex. Outcome measures assessing impulsivity and aggression will be collected for up to 1 month following the last tDCS session. DISCUSSION: The results of this study may pave the way for developing targeted interventions for impulsivity and aggressive behaviours in people with IDD.

Psychiatry in the federal correctional system in Canada.

The unique challenges of the correctional healthcare environment are well-documented. Access to community-equivalent care, voluntary informed consent of offenders with mental disorder, violence risk, suicide risk, medication misuse, and clinical seclusion, confinement and segregation are just a few of the challenges faced by correctional psychiatric services. This paper shares experiences for dealing with the ongoing challenges for psychiatrists working in the field. It provides an overview of the current state of mental healthcare in the federal correctional system in Canada, the legislative framework and initiatives aimed at addressing the healthcare needs of federal inmates.

International overview of phallometric testing for sexual offending behaviour and sexual risk.

Phallometry is an objective method of assessing male sexual arousal. The main applications in forensic psychiatry concern the evaluation of men charged with or convicted of sexual offences, the evaluation of those with suspected paraphilias not subject to the criminal justice system, risk assessment and measurement of response to sex offender treatment. In some jurisdictions, phallometry is incorporated into legal decisions about release from custody or discharge from secure hospitals. This paper provides a brief overview of the international development of phallometry, considers challenges to its broader adoption and discusses future directions for research and clinical practice.
