“ Abstract Idiopathic Parkinson's disease (PD) is a neurodegenerative disorder characterized by the dysfunction of dopaminergic dependent cortico-basal ganglia loops and diagnosed on the basis of motor symptoms (tremors and/or rigidity and bradykinesia) . Post-mortem studies tend to show that the destruction of dopaminergic neurons in the substantia nigra constitutes an intermediate step in a broader neurodegenerative process rather than a unique feature of Parkinson's disease, as a consistent pattern of progression would exist, originating from the medulla oblongata/pontine tegmentum. ”

“ We now know that the tremor and rigidity characteristic of Parkinson's disease are caused by a chemical deficiency in the part of the brain that controls movement. Through research, scientists have discovered that certain drugs can help overcome this deficiency. Many Americans with Parkinson's disease have found that with medication, physical therapy, and emotional support from families and friends, they can lead normal and productive lives.
Superbly trained scientists are hard at work trying to solve the problems caused by Parkinson's disease.

Localization of the cluster of significant volume reduction in PD compared with HC. The significant cluster located in the medulla oblongata/pons is superimposed as a red blob on the mean normalized anatomical scan of all participants. ”
