Parkinson’s disease is a motor system disorder that results from loss of brain cells that produce a chemical called dopamine. It usually affects people over the age of 50.
The main symptoms of Parkinson’s disease include trembling in hands, arms, legs, jaw and face; stiffness of the limbs and trunk; slowness of movement; and impaired balance and coordination. The disease develops subtly and gradually and progresses at different speeds in different people. As it progresses, patients find it harder to walk, talk and complete simple tasks.
Other symptoms of Parkinson’s disease include emotional changes, depression, difficulty in swallowing and chewing, problems with speaking, urinary problems, constipation, sleep disruption and skin problems.
