Parkinson's Disease Research

Parkinson's disease (PD) is a degenerative disease of the central nervous system that often impairs motor skills, speech, and other functions. Symptoms of the disease include resting tremor, bradykinesia and rigidity. The primary symptoms are the result of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine, which is produced in the dopaminergic neurons of the brain. Symptoms of the disease appear once 50-80% of dopamine neurons have died. Parkinson's disease is both chronic and progressive.
