It can be difficult to determine for yourself if you are depressed, as the symptoms are often similar to what Parkinson’s disease can cause.
For example, fatigue, sleep disturbances, motor slowdown and loss of emotional expression can be interpreted as symptoms of depression, when they are likely caused by Parkinson’s disease itself.
If you suspect you have symptoms of depression, consult your doctor or a psychologist who can make the diagnosis. He will help you distinguish between the symptoms of depression and those of Parkinson’s disease. He will probably have you fill out questionnaires in order to better establish the diagnosis.
You can also take your own depression test and bring the results to your doctor or psychologist.
