Impulse Control Disorder Among Parkinson's Disease Patients
The goal of this observational study is to learn about impulse control disorders in Parkinson's disease patients.

The main question: it aims to answer:

Detect Relative frequency of impulse control disorder among Parkinson's disease patients
Detect Relation between impulse control disorders, and other non motor and motor symptoms in Parkinson's disease patients, using clinical, neurophysiological and radiological assessment
- EligibilityCriteria: Inclusion criteria:  The study will include patients with Parkinson's disease, diagnosed according to the UK Parkinson's Disease Society Brain Bank criteria.
