Parkinsons disease (PD) is a long term disorder of the central nervous system that mainly affects the motor system. Parkinsons disease (PD) is a chronic and progressive movement disorder, meaning that symptoms continue and worsen over time. The cause is unknown, and although there is presently no cure, there are treatment options such as medication and surgery to manage its symptoms. The term Parkinsonism is used for a motor syndrome whose main symptoms are tremor at rest, stiffness, slowing of movement and postural instability. Parkinsonian syndromes can be divided into four subtypes, according to their origin: primary or idiopathic, secondary or acquired, hereditary Parkinsonism, and Parkinson plus syndromes or multiple system degeneration.
