Myth No. 2: Parkinson’s only causes problems with your movement.
Doctors have found a host of non-motion-related symptoms for Parkinson’s, some of which occur years before the motor difficulties begin. Early signs include constipation, sleep disorders (such as acting out dreams), impairment of the sense of smell, depression, anxiety and blood pressure changes. Cognitive issues, including delusions and hallucinations, can occur in later stages.
