The purpose of this study is to understand why patients with multiple system atrophy, Parkinson’s disease, Parkinson’s disease with autonomic failure, and dementia with Lewy bodies have a fall in blood pressure on standing up. It is believed that different patients develop these symptoms for different reasons. The reasons could be:

• damage to nerve supply to the legs

• the autonomic nerves are not working properly

• the brain is not controlling blood pressure or heart rate properly

This study will look at these different reasons.
