Parkinson's disease is a degenerative disease of the nervous system. It has a slow and inconspicuous onset, and it progresses gradually. The disease itself does not affect the patient's lifespan, as it does not impact the functions of heartbeats or breathing. If treated properly, cared for promptly, medications are taken as prescribed by the doctor, and followed up long-term, patients can survive about twenty years without problems. However, if patients adjust their medications on their own, stop taking their medications without consultation, or receive improper care from family members leading to accidental injuries or complications such as lung infections, then their lifespan can be significantly shortened. Once bedridden, life expectancy may rapidly decline. Therefore, with proper treatment and care, patients with Parkinson's disease can survive for about ten to twenty years. If care and treatment are not managed properly, patients may be threatened by fractures or lung infections, potentially reducing their lifespan to about five to ten years.
