Definition
Parkinson’s disease (PD): a syndrome defined in life by clinical criteria involving tremor at rest, rigidity, slowness and paucity of movement, and altered posture, gait, and balance with the absence of “atypical” features (Lang and Lozano 1998a,b). It is defined at autopsy by strict pathological criteria including the loss of neurons in the pars compacta of the substantia nigra, locus ceruleus and dorsal motor nucleus of the vagal nerve, and the presence of Lewy bodies.
Pharmacological Properties
Although Parkinson’s disease (PD) is classified as a “movement disorder,” it should also be considered a “neurobehavioral” disorder. The diagnosis of PD is based on the presence of clinical criteria having to do purely with movements and the absence of exclusionary or atypical features such as dementia, hallucinations, and corticospinal track findings (Lang and Lozano 1998a, b). The only objective study of value is the DaT (dopamine transporter) scan which identifies a dopamine...
