Impulse control disorders (ICDs) in Parkinson's disease (PD) comprise a class of psycho-behavioral disorders often associated with dopamine agonist treatment. The aim of our study was to determine the prevalence of ICDs in a group of Moroccan PD patients and to bring forward some specific aspects in our population. One hundred twenty-five PD patients, without memory impairment and treated for at least six months, were studied. They were questioned about ICDs using the QUIP-RS, and simultaneously evaluated on the motor symptoms and their treatment. Our sample was then divided into two groups: ICDs (+) and ICDs (−) groups. ICDs were identified in 28% of patients: pathological gambling in 3.2%, compulsive sexual behavior in 7.2%, pathological buying in 9.6%, eating behavior disorder in 7.2%, punding-hobbyism in 11.1%. At least two ICDs were found in 14% of patients and dopamine dysregulation syndrome in 10.4%. We also noticed another kind of “ICDs-mimics” specific to our own social context such as “excessive charity” in 18.4%, or excessive reading of the Qur’an in 9.6%. These aspects were not included in the calculation of ICDs prevalence. The ICDs (+) group was younger than the ICDs (−) group (P=0.042) and ICDs were more frequent in men (P=0.031). Dopamine agonist equivalent daily dose (DAED) was significantly higher (P=0.01) in the ICDs (+) group. There are no differences between classes of dopamine agonist used. Young age, male gender and DAED are risk factors for the occurrence of ICDs in Moroccan PD patients, as already described in the DOMINION cohort, but the prevalence found in our study was higher. We highlighted some specific ICDs-mimics in our Arab-Muslim population.Le texte complet de cet article est disponible en PDF.
