RESUMO
BACKGROUND: Nonmotor symptoms of Parkinson disease significantly hamper the quality of life of patients and have prognostic significance. AIM: To evaluate the presence of nonmotor symptoms in patients with Parkinson disease. MATERIAL AND METHODS: A structured interview was carried out in 32 patients aged 74 ± 9 years (53% men) with Parkinson disease asking specifically for impulse control disorders and dopaminergic dysregulation. The following scales were also applied: Hoehn & Yahr scale, Montreal Cognitive Assessment, Geriatric depression scale, Nonmotor symptom scale and REM sleep scale. RESULTS: A high frequency of nonmotor symptoms was recorded, specially mood, sleep, urinary and gastrointestinal problems and impulse control disorders. CONCLUSIONS: Nonmotor symptoms must be actively sought and managed in patients with Parkinson disease.
