Non-motor symptoms of Parkinson's Disease
We have developed an online study (English and French) to better understand some aspects of abnormal perceptions in Parkinson’s disease and the effects of a cognitive task on hallucinations. This online study is completely anonymous and secure. Participation is voluntary. It includes questionnaires to fill in and a small experimental task on visual perception.
- is open to all people over 50 years of age
- is addressed to all people suffering from Parkinson’s disease, but also to those who do not suffer from it because we also need to constitute a “control” group, i.e., a comparison group.
- is conducted on a computer
- is conducted in a quiet environment
- is conducted individually (not in a group)
- lasts about 20 minutes
For the scientific validity of this research, we need as many people as possible to participate. This study will help to better determine the number of people with Parkinson’s disease who suffer from hallucinations, as current estimates vary widely, ranging from 30% to 60% of people, depending on studies.
