Signs and Symptoms of Parkinson's Disease

Parkinson's disease is a progressive neurological disorder marked by a decrease in dopamine production in the brain. It is typically characterized by muscle rigidity, tremor, slowed movement, and difficulties with posture and balance. Common signs and symptoms of Parkinson's disease can include slurred speech, depression, insomnia, constipation, and fatigue. As the disease progresses, patients may also experience difficulty walking, decreased facial expression, and dysphagia (difficulty swallowing). The exact cause of Parkinson's disease remains unknown, however, it has been linked to genetics, environmental toxins, and virus. Treatment typically involves lifestyle changes, medications, and sometimes surgery. Early recognition of symptoms can play a key role in managing the disease, as the disease is difficult to reverse once it has progressed.
