Paraphilic behaviours in a parkinsonian patient with hedonistic homeostatic dysregulation

Abstract

Hedonistic homeostatic dysregulation (HHD) is a well-known neuropsychiatric complication described in patients with Parkinson's disease (PD), characterized by misuse of and addiction to dopaminergic drugs (Giovannoni et al., 2000). Previous reports have indicated HHD in approximately 3.4% of PD patients, more frequently in males with early onset of the disease (Pezzella et al., 2005). Copyright © 2005 CINP.
