Dr. Dinah Buckhoy
Parkinson's Disease is a homeostatic imbalance of the CNS caused by degeneration of the neurons that extend from the substantia nigra to the putamen and caudate nucleus that release dopamine.
The caudate nucleus of the basal nuclei contain neurons that release ACh.
The imbalance of too much ACh and too little DA is what causes the sx's of PD.
While the cause of PD is unknown, toxic substances such as pesticides and CO are contributing factors. Only 5% have a family h/o.
Prognosis depends on the age at diagnosis.
PD usually progresses slowly in patients who are diagnosed at a younger age but progresses quickly in elderly patients.
