Specializes in Psychiatry

Parkinson's causes: Specific gene mutations play a role and genes changed due to environmental exposure may be causal. Having a close relative who has it increases your risk. The triggers are felt to be virus or toxins (herbicides or pesticides). Changes in the brain of parkinson patients include: lower dopamine, lower norepinephrine, and the presence of lewy bodies.
