Parkinson's disease

Parkinson's disease is a progressive neurological disorder that affects movement. It occurs when nerve cells in the brain that produce dopamine—a chemical that helps control movement—start to break down or die. This can lead to symptoms like tremors, stiffness, slowness of movement, and balance problems. People with Parkinson's may also experience changes in mood or sleep. While there is no cure, various treatments, including medication and therapy, can help manage symptoms and improve quality of life. The disease typically affects older adults, but it can occur in younger individuals as well.
