Study Notes
Parkinson's Disease
- The reduction in the activity of inhibitory dopaminergic neurons in Parkinson's disease is correlated with the substantia nigra part of the brain.
Etiology
- Pesticide exposure is not listed as a possible etiology of Parkinson's disease.
Medications
- Reserpine is an example of a medication that reduces the amount of dopamine in the brain.
Symptoms
- Festinating gait involves a characteristic fast shuffling gait and difficulty in starting and stopping while walking.
Pathophysiology
- The main imbalance between neurons that contributes to many symptoms of Parkinson's disease is an imbalance between dopamine and acetylcholine.
