Description
Parkinson’s Disease (PD) is a progressive neurological disorder that primarily affects movement, with symptoms typically appearing after age 60. The disease involves a wide range of motor and non-motor symptoms, including cognitive and emotional changes. While PD is progressive, it’s not a death sentence; many people live long, fulfilling lives with proper management.
PD occurs when certain nerve cells (neurons) in the brain gradually break down or die. The neurons that are most affected make a chemical called dopamine that helps different parts of the brain communicate. Without enough dopamine, the brain can’t send clear signals about how to coordinate movement. This is why people with Parkinson’s might shake, move slowly, or have trouble with balance. Lack of dopamine also affects mood, thinking, and even some automatic body functions like digestion.
This process happens very slowly over many years. By the time someone notices symptoms, many of these special neurons have already died. It is not known why these neurons start dying in the first place, but science indicates a mix of genetic and environmental factors.
