If a loved one has survived a stroke, you are likely filled with relief, as stroke is the fourth leading cause of death in the United States. But despite the stroke not being fatal, recovery can often feel like the start of an uphill battle. Depending on the severity of the stroke and how long blood was blocked from the brain, it may take months or even years to regain functions. Because the brain was deprived of oxygen, and brain cells may be severely damaged or lost, it is very common for stroke survivors to lose cognitive and physical abilities.
