Parkinson's disease and other movement disorders are conditions that affect the nervous system, causing changes in movement and coordination. Parkinson's disease is characterized by tremors, stiffness, slow movement, and difficulty with balance and coordination. Other movement disorders include essential tremor, dystonia, and Huntington's disease. These conditions can have various causes, including genetic factors, environmental factors, and damage to the brain's structures. Symptoms can be managed through medication, physical therapy, and lifestyle changes. While there is no cure, treatment can help improve the quality of life and alleviate symptoms. Early diagnosis and ongoing care are essential for managing these conditions effectively.
