¢Parkinson's disease belongs to a group of conditions called movement disorders. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia). The primary symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine, which is produced in the dopaminergic neurons of the brain. Secondary symptoms may include high level cognitive dysfunction and subtle language problems. PD is both chronic and progressive.
¢PD is also called "primary parkinsonism" or "idiopathic PD" (classically meaning having no known cause although many genetic mutations associated with PD have since been discovered).

~For our information,many types of drugs are used in medication to threatment these symstoms.. For example; "ledovopa+other drugs"..
