Parkinson's disease Parkinson's disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system.[1] The symptoms generally come on slowly over time.[1] Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking.[1] Thinking and behavioral problems may also occur.[2] Dementia becomes common in the advanced stages of the disease.[2] Depression and anxiety are also common, occurring in more than a third of people with PD.[2] Other symptoms include sensory, sleep, and emotional problems.[1][2] The main motor symptoms are collectively called "parkinsonism", or a "parkinsonian syndrome".[4][8]
Movement disorders Hypokinetic movement disorders refer to akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement) and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder. In secondary movement disorders, the abnormal movement is a manifestation of another systemic or neurological disorder.[3]
