Clinical profile of compulsive sexual behaviour and paraphilia in Parkinson's disease.

This case control study compares the clinical and demographic profile of Parkinson's disease (PD) participants with compulsive sexual behaviour (CSB) to those with other impulse control disorders (ICDs) and those with no behavioural disorder. We found a higher dopaminergic load (p < 0.05) and higher levels of anxiety (p < 0.01) in the CSB group compared to the PD control group. On the NEO-FFI, a measure of personality style, the CSB group was significantly 'more open to new experiences' (p < 0.05) and significantly 'less agreeable' (p < 0.01) compared with the other two groups. Results suggest that manifestation of specific types of ICDs may be associated with distinct risk profiles; this understanding may aid early identification and trigger intervention.
