Parkinson’s disease (PD) is a chronic and progressive neurological movement disorder that primarily affects older adults. It occurs when nerve cells in the brain gradually lose their ability to produce dopamine, a chemical messenger that helps control movement and coordination. As dopamine levels decrease, patients may experience symptoms such as tremors, muscle stiffness, slowed movements, and balance difficulties. PD most often appears after the age of 60, though some younger individuals may also be affected. Recognizing these signs early and seeking medical support can help patients better manage the condition and maintain quality of life.
