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.
