What's the maximum number of strokes a human can endure and live?
Strokes, a leading cause of mortality and disability worldwide, particularly in older adults, can have severe and lasting effects on an individual's health and life expectancy. A recent study reveals that the number of strokes a person experiences significantly worsens their long-term health outcomes, increasing both mortality risk and disability burden.
Recurrent strokes tend to compound neurological damage, leading to greater functional impairment and higher dependency on long-term care. The risks of having another stroke are different for those who have already experienced a transient ischemic attack (TIA), with each event increasing the likelihood of future strokes.
The consequences of stroke are far-reaching. Stroke is a leading cause of long-term disability, and recurrent events typically increase the need for long-term care, reducing quality of life. A significant proportion of stroke survivors, 70.6% of people who had an ischemic stroke and 79% of those who experienced intracerebral hemorrhage, are either deceased or completely dependent on caregivers five years after the initial event.
The risks associated with stroke are further exacerbated by age, as older adults are more likely to die and become impaired after a stroke compared to their younger counterparts. People ages 65 and older are over seven times more likely to die within a short time of having a stroke than those who had a stroke between 18 and 54 years.
The risks of stroke are also influenced by metabolic and vascular risk factors, such as high blood pressure and high LDL cholesterol. Although stroke mortality has been declining in some regions due to improved treatments, the absolute number of stroke cases - and thus recurrent strokes - is projected to rise as populations age.
Effective prevention and aggressive management of stroke risk factors and rehabilitation are critical to reducing recurrent strokes and improving long-term outcomes. However, recurrent stroke events still predict worse survival and more profound disability.
Inequalities in healthcare access, quality, and health insurance coverage further contribute to these health disparities. The U.S., for instance, has significant health disparities between racial and ethnic groups in terms of stroke care, with Black, Hispanic, Native American, Native Alaskan, Hawaiian Natives, and Pacific Islander groups having higher stroke incidence rates than white people.
Each stroke can affect a person's ability to perform various daily tasks, such as speaking clearly, moving one side of the body with good control, safely chewing and swallowing, seeing out of all visual fields, or walking safely. The more damage the brain sustains, the more likely complications could be fatal, such as falling due to weakness or developing pneumonia (due to swallowing difficulty and food going down into your lungs).
It is essential to understand that there is no defined limit to the number of strokes a person can have without dying. Prevention and early intervention are crucial in reducing the risk of recurrent strokes and improving long-term outcomes.
