0.375 -> - [Narrator] Strokes are
sometimes called brain attacks,
3.07 -> and for good reason.
4.43 -> Strokes are medical emergencies
6.27 -> that cause injury to the brain,
8.03 -> which can lead to paralysis
and problems with speech,
10.99 -> cognition, vision, and other functions.
13.94 -> There are two kinds of strokes,
ischemic and hemorrhagic.
18.07 -> Ischemic strokes, the most common kind,
20.38 -> happen when a blood clot
21.53 -> cuts off the brain's supply
of oxygen-rich blood.
24.97 -> The clot can form in a
blood vessel in the brain
28 -> or somewhere else in
the body like the heart
30.09 -> and travel to the brain.
32.19 -> Without blood, brain cells
immediately start to die.
35.5 -> In just two minutes,
36.61 -> someone can lose nearly
2 million brain cells.
40.42 -> A hemorrhagic stroke happens
41.78 -> when an artery in the
brain leaks or ruptures.
44.84 -> Pressure from the blood damages
the surrounding tissues.
48.11 -> When you're having a
stroke, every second counts.
50.82 -> The longer you wait to get medical help,
52.82 -> the more damage can occur.
54.82 -> To spot warning signs of
stroke, remember FAST.
58.46 -> F is for face. Is one
side drooping or numb?
62.05 -> A is for arm. Is one arm weak or numb?
65.75 -> S is for speech.
67.16 -> Is speech slurred, or is
the person unable to speak?
70.8 -> T is for time to call 9-1-1
73.55 -> if the person shows any of these symptoms,
75.94 -> even if they disappear.
78.43 -> For stroke patients who get
to the hospital quickly,
81.23 -> doctors can administer a drug
called tPA to dissolve clots.
85.32 -> In some cases they may perform surgery.
88.22 -> A transient ischemic attack,
also known as a mini-stroke,
91.53 -> can be a warning of future stroke.
94.23 -> Symptoms are the same
as those of a stroke,
96.38 -> but they typically last
for only a few minutes
98.61 -> up to 24 hours, and then disappear.
101.52 -> It's still important to
call 9-1-1 right away.
105.17 -> To reduce your risk of stroke,
106.87 -> seek treatment if you have
an irregular heartbeat,
109.11 -> known as atrial fibrillation or AFib,
111.7 -> which makes a stroke more likely.
113.91 -> Control your blood pressure,
115.83 -> maintain healthy blood sugar
and cholesterol levels,
119.02 -> eat a healthy, plant-based
diet, exercise regularly,
123.68 -> avoid excess alcohol, meaning no more
126.08 -> than one drink a day for
women and two for men,
129.09 -> maintain a healthy weight,
and if you smoke, quit.
134.06 -> These steps are also good for your heart,
135.88 -> so by following them you can help
137.74 -> protect both your brain and
your heart from an attack.
141.523 -> (gentle music continues)
