Michelle Dedeo is a Neuroscience Clinical Nurse Specialist with Seattle's Providence Swedish hospital. She is also a volunteer medical expert for the American Heart Association, and in the wealth of information she provides, underscores calling 911 when stroke is suspected, for the best chance at a positive outcome. When one suffers a stroke, the brain is not functioning correctly, thus the individual may not be aware of what is happening. Therefore, it's important for all to be aware of symptoms and intervene when needed.
