How are depression and Parkinson’s disease related?

People with any chronic (long-term) disease may experience depression. These diseases can trigger strong feelings about symptoms, physical limits and the possibility of death.

People with Parkinson’s disease often have similar reactions. But the ties may run even deeper, as Parkinson’s disease may directly cause depression. That’s because Parkinson’s affects chemicals in your brain. These changes can lead to mood disorders like depression, anxiety and apathy (lack of motivation or drive). Depression can also intensify other Parkinson’s symptoms — speech and movement can slow even further, or forgetfulness can worsen, for example.
