Depression and anxiety are common symptoms in Parkinson’s disease (PD). While it’s normal and understandable to feel sad or worried when facing a diagnosis or progressing symptoms, mood changes in PD are more than a reaction. They are a real symptom of Parkinson’s, caused by brain chemical changes.

Depression and anxiety look different for different people. Depression can affect mood, decrease energy and cloud thinking. It also can change appetite, weight and sleep. Anxiety can lead to excessive worry or concern. Treatment options for mood changes include medication; talk therapy, or counselling; and behavioural strategies, such as exercising regularly, setting goals and doing social activities.
