“…3) Other factors that could increase the probability of gambling disorder in pd patients are: novelty seeking, personal or family background of alcohol abuse disorder (Voon et al, 2007), younger age at pd beginning (Siri et al, 2010;Voon et al, 2007), male gender (Siri et al, 2010), longer term of disease, more severe psychotic symptoms, more severe anxiety, more severe depression (Pontieri et al, 2015), older age, later onset of gambling disorder, and augmented bingo playing (Jiménez-Murcia et al, 2012). 4) On the other hand, possible variables that could increase the incidence of other impulse control disorders (for instance: hypersexuality, compulsive eating or compulsive shopping) in pd patients are: younger age of pd disease onset (Pérez-Lloret et al, 2012;Weintraub, 2009;Weintraub et al, 2010), male gender (Weintraub, 2009), unmarried (Weintraub et al, 2010), longer pd duration (Pontieri et al, 2015), mental disorder-related factors like disorder's severity (psychotic, anxiety or depression; Pontieri et al, 2015), impulsiveness, personal history of a disorder (substance abuse, bipolarity or impulse control; Weintraub, 2009), and current cigarette smoking (Weintraub et al, 2010). Finally, the presence of family background of a disorder -substance abuse, bipolarity (Weintraub, 2009), or gambling disorder (Weintraub et al, 2010)-could also increase the probability of an impulse control disorder in a pd patient.…”
