Parkinson's disease
Tremor-causing brain condition
Parkinson's disease is a progressive neurological disorder affecting movement.
It develops when nerve cells in the brain produce insufficient dopamine, causing tremors, stiffness, slowed movement, and balance problems.
Symptoms typically appear gradually and worsen over time: He was diagnosed with Parkinson's disease after noticing a tremor in his hand.
Named after English physician James Parkinson.
