Parkinson's Disease is a progressive neurological disorder that primarily affects movement. It occurs when nerve cells in the brain that produce dopamine, a chemical responsible for coordinating movement, begin to deteriorate. This leads to symptoms such as tremors, stiffness, and difficulty with balance and coordination. As the disease progresses, individuals may also experience non-motor symptoms, including sleep disturbances, depression, and cognitive changes. While there is currently no cure for Parkinson's Disease, various treatments, including medications and therapies, can help manage symptoms and improve quality of life for those affected.
