Most people associate Parkinson’s disease (PD) with tremors, a motor symptom. However, non-motor symptoms are common and can be more troublesome and disabling than motor symptoms. They can include cognitive changes, mood and sleep disorders, autonomic symptoms or weight loss.
Like people with other chronic diseases, people with Parkinson’s disease (PD) often struggle with mental health difficulties. While the illness is known to impair many aspects of movement, research from the Parkinson's Outcomes Project has found that two non- motor symptoms — depression and anxiety — play a key role in the disease as well and its effect on people’s quality of life.
