Signs and Symptoms of Parkinson's Disease

Parkinson's disease is a progressive neurological disorder that affects movement, speech, and other bodily functions. It is caused by a lack of a brain chemical called dopamine, which is responsible for coordinating movements. The most common signs and symptoms of Parkinson’s disease are tremor (shaking), slowness of movement, rigidity or stiffness of the limbs, and loss of balance and coordination. Additionally, people with Parkinson's may experience changes in their facial expressions, posture, and gait. Other non-motor symptoms can include sleep disturbances, cognitive impairment, and depression. Early diagnosis and treatment can help manage some of the symptoms and slow the disease’s progression. Treatment options include medication, rehabilitation, and deep brain stimulation.
