After a stroke, you probably have a lot of questions and concerns about how -- and even if -- you will recover. When will you be able to move your arms? Is your independent life gone forever?
It's difficult to predict to what degree someone will recover after a stroke, says Randie M. Black-Schaffer, MD. Schaffer is medical director of the Stroke Program at Spaulding Rehabilitation Hospital in Boston. "How quickly a patient recovers in the first few weeks," she says, "can give us an indication of how much damage occurred, and we can make some educated guesses based on that."
Have you had a stroke? How could you tell?
A stroke is a sudden stop of blood supply to part of the brain. Some people have strokes without ever knowing it. These so-called silent strokes either have no easy-to-recognize symptoms, or you don’t remember them. But they do cause permanent damage in your brain.
If you've had more than one silent stroke, you may have thinking and memory problems. They can also lead to more severe strokes.
According to the National Institute of Neurological Disorders and Stroke, how well you recover depends upon the type of stroke you had, how much brain damage occurred from the stroke, your age, and how quickly rehabilitation begins.
Black-Schaffer advises learning all you can about what caused your stroke and what you can do to avoid further health problems. Use the following questions as a guide when you talk with your doctor about what to expect in the months and years ahead.
1. What caused my stroke?
Eighty percent of all strokes occur when blood flow to the brain is suddenly cut off -- usually by a blood clot or some other obstruction. This is called an ischemic stroke. A hemorrhagic stroke occurs when a blood vessel ruptures in the brain.
Knowing the type of stroke you had can help your doctor determine the underlying cause. For example, an ischemic stroke may be caused by a blocked artery due to the buildup of plaque -- a mixture of cholesterol and other lipids, or blood fats. People with atherosclerosis, or hardening of the arteries from plaque buildup, are more at risk for this type of stroke. High blood pressure is a common culprit in hemorrhagic stroke. Both of these conditions increase the risk of stroke, and managing them can help prevent a second stroke.
2. Am I at risk for a second stroke?
The overall risk of a second stroke is highest right after a stroke. Three percent of survivors have a second stroke in the first 30 days, and one-third will have another within two years.
