Is there a need for elderly forensic psychiatric services?

The population of the elderly in most developed nations is on the increase. Furthermore, the prevalence of mental disorder amongst elderly offenders is high. The true extent of 'elderly' crime is unknown because much of it goes undetected and unreported. This leads to a failure to detect mental illness in such offenders. Court diversion schemes may improve recognition of mental illness but these schemes usually tend to deal with the more severe crimes. This may result in an overestimation of the amount of serious crime committed by the elderly and a failure to detect mental illness amongst those who commit less serious crimes. Efforts to service this hidden morbidity call for multi-agency collaboration. Improved detection and reporting of crimes is essential if mental health difficulties in the elderly are not to go unnoticed. The needs of elderly mentally-disordered offenders are complex and fall within the expertise of old age and forensic psychiatry, without being adequately met by either one. Therefore, consideration should be given to the development of a tertiary specialist forensic old-age psychiatry service.
