Diseases » Parkinson's Disease




Parkinson’s disease (PD) is a chronic progressive neurodegenerative movement disorder. It is characterized by muscle rigidity, tremor, slowing or loss of physical movement. It affects nerve cells or neurons, in a part of brain that controls muscle movement. Parkinson’s result from degeneration of nuclei in a number of dopamine-producing nerve cells in the brain system. Dopamine is a neurotransmitter that stimulates motor neurons that control the muscles. When this dopamine production is depleted, the motor system nerves are unable to control movement and coordination. Parkinson’s disease is also called as idiopathic Parkinson’s because the cause for condition is unknown.

Parkinson’s usually begins around age 60 and may be little earlier. It is seen more common in men than women. This disease is not contagious.
