“Stroke is extremely common and really disabling—but most strokes can be prevented.”
That’s the message Christopher Ray, MD, a WashU Medicine neurologist who cares for stroke survivors, wants more people to hear.
Nearly 800,000 people in the U.S. experience a stroke each year. Survivors face a higher risk of another one, which makes prevention even more critical after a first stroke. Dr. Ray works closely with his patients at Barnes-Jewish Hospital to identify what caused their stroke and to develop a personalized plan to reduce future risk.
Prevention after a stroke usually involves several approaches working together. Depending on the cause, medications may be used to help prevent clots or blockages. Many patients also benefit from structured rehabilitation programs that combine exercise with education and counseling, along with ongoing management of key risk factors.
“Up to 80% of strokes may be prevented by managing blood pressure, cholesterol, blood sugar, and heart rhythm issues—and by making healthy lifestyle choices,” Dr. Ray explains. “Aerobic exercise is one of the most important things people can do to lower their stroke risk.”
Prevention matters, but so does recognizing the signs of a stroke. The most common are identified in the acronym BE FAST:
B – Balance loss
E – Eye or vision changes
F – Facial drooping
A – Arm or leg weakness
S – Speech difficulty
T – Time to call 911
“Most stroke doctors have seen strokes across the entire age spectrum,” Dr. Ray shares. “That’s why everyone—not just older adults—needs to know the signs.”
If symptoms appear, call 911 right away. “Calling 911 allows paramedics to begin care immediately and alerts the hospital’s stroke team before the patient arrives,” Dr. Ray says.
For Dr. Ray, awareness is crucial—because strokes that aren’t prevented or treated quickly can change a life in an instant.
“Living a healthy lifestyle, seeing your doctor regularly, and knowing when to call 911 can make a real difference,” he says. “When symptoms show, don’t wait.”
