The exact length of time a hemiplegic patient can live depends on the age of the patient as well as the patient’s underlying disease, the presence of complications and the care provided by family members. If the patient has hemiplegia alone, in the absence of complications, life expectancy is usually not affected, mainly the patient’s quality of life, but if the patient has complications when treatment is less effective, the mortality rate is higher. When the patient is younger and has no underlying disease or complications of cerebral infarction, and the family takes better care of the patient, the patient can usually survive for many years without affecting life expectancy. If the patient is old and frail, with more underlying diseases, poor cardiopulmonary function and complications of cerebral infarction, and poor care by family members, the patient’s life may only last for about six months or even shorter. Therefore, the survival time of hemiplegic patients varies according to their individual conditions. It is recommended that hemiplegic patients actively cooperate with doctors in treatment and rehabilitation to improve the quality of life and the prognosis.
