Anhedonia is present in Parkinson's Disease (PD) as well as in addictive behaviors. Pathological Gambling (PG) and other Impulse Control Disorders (ICDs) have emerged as iatrogenic complications associated with dopamine replacement therapy. We studied 154 PD patients, divided into three groups: 11 with PG, 23 with other ICDs (compulsive buying, hypersexuality, binge eating), 120 without ICDs. All patients underwent a thorough clinical, neuropsychological and psychiatric evaluation. The PG-group, compared to the ICDs-group and PD-controls, reported a significantly higher incidence of anhedonia (45% vs. 9% vs. 14% respectively), higher Snaith–Hamilton Pleasure Scale (SHAPS) scores (2.0±1.3 vs. 1.0±1.1 vs. 1.0±1.2), higher levels of impulsivity traits as measured by the Barratt Impulsiveness Scale (70.0±10.6 vs. 64.8±11 vs. 60.9±9.3) and more severe frontal dysfunctions (Frontal Assessment Battery, FAB: 12.4±4.9 vs. 15.5±1.6 vs. 14.4±3). A model for PG (incorporating anhedonia, impulsivity levels and frontal impairment) is discussed in the context of the pathophysiology of addictive behaviors. The impairment of hedonic capacity, possibly resulting from an underlying neuropsychological dysfunction, might facilitate loss of control over reward-related behavior, thus favoring the shift towards predominantly habit-based compulsive behaviors.
