Parkinsonism refers to a group of neurological disorders that cause movement problems similar to those seen in Parkinson's disease. Symptoms often include tremors, stiffness, and difficulty with balance and coordination. While Parkinson's disease is the most common form, other conditions can also lead to parkinsonism, such as multiple system atrophy and progressive supranuclear palsy. The exact cause of parkinsonism can vary, but it often involves the loss of dopamine-producing neurons in the brain. This loss affects how the body controls movement. Treatment options may include medications, physical therapy, and lifestyle changes to help manage symptoms and improve quality of life.
