Parkinson's disease is a chronic condition and a progressive degenerative disorder of the nervous system. The main symptoms include slowed movements, increased muscle tone, resting tremors, and abnormal posture and gait. The onset of the disease is slow and subtly worsens over time. Although not highly dangerous in itself and not directly life-threatening, Parkinson’s disease currently lacks a cure, and the condition gradually worsens. Generally, within about 10 to 20 years, patients may experience significant balance impairments. The main risks involve instability while walking, which can lead to falls and potentially cause fractures and other complications. In later stages, patients often become bedridden, leading to possible complications such as pulmonary infections, urinary tract infections, bedsores, and malnutrition. Therefore, Parkinson's disease is relatively mild, manageable in the early stages, but requires careful attention in later stages to prevent complications and avoid unnecessary harm.
