Parkinson’s disease is a condition that affects the brain and the nervous system. Over time, certain brain cells that help control movement become damaged or are lost. This can make everyday actions—like walking, writing, or picking up a cup—harder to do smoothly. Parkinson’s usually develops slowly and tends to affect people as they get older, though it can begin earlier.
Early signs often include a slight shaking (tremor) in a hand, stiff muscles, slower movement, and changes in balance or posture. Some people notice a softer voice, smaller handwriting, or trouble with sleep and mood. Signs usually start on one side of the body and grow over the years.
