What are the challenges to diagnosing depression in people with Parkinson’s disease?
It can be difficult to tell whether a symptom is actually caused by depression or the physical effects of Parkinson’s disease. For example, Parkinson’s disease causes muscle weakness, with symptoms that may seem like depression:
- Downcast eyes.
- Flat expression.
- Lack of visible emotions.
- Slow speech.
Parkinson’s can also cause apathy, which can look like depression, with symptoms like:
- Loss of interest in previously enjoyable activities.
- Flat expression.
- Losing interest in eating or taking care of yourself.
Similarly, other symptoms can come from either Parkinson’s disease or depression:
- Fatigue or less energy.
- Low sexual function.
- Trouble sleeping.
- Weight loss.
- Memory loss.
