Abstract/Results: | ABSTRACT:
The hypothesis under investigation in this study in that early onset alcohol abuse is a factor underlying impulsive violence particularly amongst personality disordered offenders. The study has recorded forensic and substance abuse histories, psychometric information, Contingent Negative Variation (CNV) and performance on the Iowa Gambling Task (IGT) in Personality Disordered patients in Broadmoor. Most prevalent diagnostic category is Anti-social personality disorder. CNV was first described by Grey Walter in 1964. Howard et al (1982), studying special hospital patients reported that, using a symmetrical avoidance paradigm, CNV differentiation was inversely related to psychometric Impulsivity. Previous study indicates that early onset alcohol and drug use is highly prevalent amongst high secure psychiatric patients in the England and Wales jurisdiction (Lumsden et al 2004). This potential risk factor may lead to reduced frontal lobe function. Multi-channel electrophysiological recording of the CNV were collected as a measure of frontal lobe (possibly anterior cingulate) function (Stephan et al 1995). Results are presented from the study relating electrophysiological function (CNV), neuropsychological function (IGT), psychometric/personality profiles (UPPS and IPDE) with behavioural measures (offending and substance use histories and ongoing behaviour in the hospital). Age of onset of alcohol abuse in combination with personality variables is a factor relating to offending and IGT performance.
