disease is a neurodegenerative disease that currently
affects about 0.5 million people in the U.S. The disorder
is characterized by nerve cell loss in a region of
the brain associated with coordination of movement.
The condition results in learning and memory deficits
and a profound movement disorder with tremors and
progressive rigidity. A number of drugs are currently
available which treat the symptoms of the disorder
but do not affect the underlying neurodegeneration.
