  parkinsonism \parkinsonism\ n.
     A degenerative nervous disorder occurring mostly in persons
     older than 60 years, characterized in advanced stages by
     rhythmic muscular tremors, especially in the hands, and by
     rigidity of movement, a drooping posture, slow speech, and a
     masklike facial expression; the term designates a set of
     symptoms, and the underlying disease causing these symptoms
     is most commonly Parkinson's disease. Parkinsonism results
     from a deficiency in the neurotransmitter dopamine caused by
     degeneration of the cells producing that agent. It can be
     mitigated by chemotherapy with agents such as levodopa

                Neurology, found the lifetime risk of developing
                parkinsonism is 7.5 percent, three times higher
                than previously thought.            --UPI (Jan. 2,
