[Impulsive-compulsive syndrome in Parkinson's disease].

Dopaminergic replacement therapy (DRT) is effective in treatment the motor symptoms of Parkinson's disease (PD) but can lead to impulse control disorders (ICD) in some patients. ICD include pathological gambling, hypersexuality, compulsive shopping, binge eating, punding, dopamine dysregulation syndrome (DDS). Authors studied the prevalence of ICD and its impact on the quality of life and daily activities of PD patients and their relatives. Among 246 patients studied, 55 patients (23%) (28 men, mean age 66.5±9.4 years) were diagnosed with ICD. DDS was noted in 36.4%, punding in 36.4%, binge eating in 23.6%, hypersexuality in 14.5%, compulsive shopping in 14.5% and pathological gambling in 1.8%. Of these 55 patients, 10 (18.1%) had symptoms of 2 of the ICDs: 3 (5.45%) had 3 of the ICDs and 2 (3.63%) patients had 5 of the ICDs. Quality of life ranged from 25% to 89%. Treatment approaches including the adjustment of doses of levodopa and dopamine receptor agonists in PD patients with ICD are presented.
