Stroke:
Treatment for Ischemic Stroke
A
stroke happens when blood flow to the brain stops. Brain cells
in the area begin to die, either because they stop getting the
oxygen and nutrients they need to function, or they are killed
by the rupture of the vessel and sudden spill of blood.
Stroke Facts & Treatment
Stroke is the third leading cause of death in the United
States, and a leading cause of disability. In recent years, the
clot-busting drug tissue plasminogen activator, known as TPA,
has shown promise in treating the effects of stroke but only if
it's administered within three hours of the onset of symptoms.
TPA dissolves the clot or clots that are keeping blood from
flowing to the brain. Because damaged brain cells can linger in
a compromised but potentially viable state for several hours,
the sooner treatment begins the better the chances of surviving
without disabilities.
Valley Baptist-Harlingen uses TPA when indicated to reverse
strokes. The ability to carry out this procedure requires an
advanced level of personnel and technical support. Doctors say
the unfortunate fact about TPA is that so few people meet the
criteria to actually receive it because they arrive too late to
the emergency department.
Dr. Michael Mohun, Chief of Emergency Room Medicine at Valley
Baptist-Harlingen says, “People need to educate themselves about
the signs and symptoms of strokes and seek medical attention
quickly. Not everyone is a candidate for TPA but it has the
potential to reverse the devastating effects of a stroke.”
Stroke Symptoms & Risk Factors
Every 3.3 minutes, someone dies of a stroke. But death
and disability figures could be reduced if more people
recognized the signs of stroke, and the importance of immediate
medical attention.
Symptoms of stroke include sudden weakness or numbness on one
side of the body including the face, arm and leg; sudden
confusion or trouble speaking; trouble walking, dizziness or
loss of balance; trouble seeing out of one or both eyes; or
sudden severe headaches with no known cause.
The longer blood flow is cut off to the brain, the greater
the potential for permanent damage. “The difference between a
stroke and a heart attack is that with heart attack, you get
crushing chest pain, and you know there's a big problem ... with
a stroke, it's more subtle,” says Dr. Mohun.
Risk factors for stroke include high blood pressure, heart
disease, smoking, diabetes, and high cholesterol. Controlling
these risk factors can decrease the likelihood of stroke.
What is the prognosis?
The effects of a stroke range from mild to severe depending
on the type of stroke, area of the brain affected, and the
extent of the damage. Those who have survived a stroke may
experience paralysis, pain, or numbness, as well as problems
with thinking and speaking, and emotional changes. Many
individuals will require physical therapy to regain strength and
mobility, and occupational therapy to re-learn how to perform
everyday activities. Speech therapy is appropriate for those who
have trouble reading, understanding speech, or forming language.
