Cause of Parkinson's disease among youngsters identified

This leads to motor symptoms including tremors, rigidity, bradykinesia (slowness of movement), and postural instability. Non-motor symptoms such as cognitive impairment, mood changes, and autonomic dysfunction may also occur. There are several factors that cause Parkinson's disease.
