| Summary: | Abstract Background Impulse control and related disorders (ICRDs) are clinically complications in Parkinson’s disease (PD). However, the clinical characteristics of ICRDs in Chinese PD patients were rarely reported. We aimed to explore the prevalence and the clinical profile of ICRDs in Chinese patients with PD. Methods 142 Chinese PD patients were consecutively enrolled. The symptoms of ICRDs were assessed with the Questionnaire for Impulsive-Compulsive Disorders. The clinical characteristics of patients with ICRDs and without ICRDs were compared. Results ICRDs were present in 31% of our patients. The most common ICRDs were compulsive medication use (11.3%) and punding (9.2%); the least frequent were walkabout (1.4%). Variables independently associated with ICRDs were earlier onset of the disease (≤55 years), severe cognitive impairment (MMSE 10–20), the dose of dopamine agonist (>1 mg/d) and dyskinesia. Conclusions ICRDs was commonly found in Chinese PD patients. Earlier onset of the disease, the dose of dopamine agonist, severe cognitive impairment and dyskinesia are independent factors associated with ICRDs. Our results will be benefit for clinicians to assess the risk of developing ICRDs before delivering dopaminergic medication.
