PARKINSON'S DISEASE DOUBLES THE RISK OF SUICIDE

Parkinson's Disease has been found to double the risk of suicide. Those factors in people with Parkinson's Disease most associated with suicide are : being male, initial extremity of motor symptom onset, history of depression, delusion, any psychiatric disorder, and higher L-dopa dosage. Other Parkinson's Disease related variables such as Parkinson's Disease symptom score (UPDRS motor score) were not significantly associated with suicide. Dopamine normally stimulates the mesocortical pathway in the brain, which is associated with emotional stimulation. Consequently, insufficient dopamine, which is what occurs in Parkinson's Disease, is associated with emotional depression.
