Does age affect stroke recovery?
Aging is the strongest nonmodifiable risk factor for ischemic stroke, and aged stroke patients have higher mortality and morbidity and poorer functional recovery than their young counterparts.
Does having a stroke shorten your life?
When compared to members of the general population, a person who has a stroke will, on average, lose 1.71 out of five years of perfect health due to an earlier death. In addition, the stroke will cost them another 1.08 years due to reduced quality of life, the study found.
