Parkinson’s Disease

It is a degenerative disorder of the central nervous system. Parkinson’s disease is a condition in which part of the brain becomes progressively more damaged over many years (a progressive neurological condition). The motor symptoms of Parkinson’s disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain; the cause of this cell death is unknown.

Parkinsonian syndromes can be divided into four subtypes according to their origin:

Primary or idiopathic
Secondary or acquired
Hereditary parkinsonism
Parkinson plus syndromes or multiple system degeneration.
