What is parkinsons diseases? Parkinsonâs occurs when certain nerve cells (neurons) in a part of the brain called the substantia nigra die or become impaired. Normally, these cells produce a vital chemicâ¦al known as dopamine. Dopamine allows smooth, coordinated function of the body's muscles and movement.
Parkinson's disease is characterized clinically by asymmetric parkinsonism (resting tremor, bradykinesia, rigidity and later postural instability) and pathologically by the loss of neurons, particularly dopaminergic neurons, in the substantia nigra that project primarily to the striatum.
