  • Why is Parkinsons disease called a brain disability/impairment, when there are obvious physical impairments associated to the limbs of those inflicted with the illness?

    In Parkinsons disease, there is degeneration of the nerve cells in the basal ganglia of the brain. These nerve cells are essential for the normal functioning of the motor system and when damaged in PD, the result is the tremor and slowness of movements.The damaged nerve cells send their messages using the transmitter dopamine and the treatment is to prescribe L-dopa (which enters the brain cells and is changed to dopamine) or similarly-acting medications.
