Stroke
A stroke occurs when blood flow to the
brain is severely slowed by a blockage
or blocked entirely. These blockages
cause cells in the brain due to lack of
oxygen and other key nutrients that are
necessary for brain function.
Diagnosis & Symptoms
The symptoms ranges based on
severity but the overall symptoms
are loss of balance, slurred speech,
drooping of face, numbness to left
side, and trouble understanding.
Diagnosing after the fact includes a
CT scan of the brain and spinal
cord.
Causes of Strokes
occurs when the blood supply to your brain is interrupted or reduced
This deprives your brain of oxygen and nutrients, which can cause your brain
cells to die
may be caused by a blocked artery (ischemic stroke) or the leaking or bursting
of a blood vessel (hemorrhagic stroke)
may experience only a temporary disruption of blood flow to their brain
(transient ischemic attack, or TIA)
About 85 percent of strokes are ischemic stroke
Categories of ischemic strokes
Thrombotic stroke. A thrombotic stroke occurs when a blood clot (thrombus)
forms in one of the arteries that supply blood to your brain. A clot may be
caused by fatty deposits (plaque) that build up in arteries and cause
reduced blood flow (atherosclerosis) or other artery conditions.
Embolic stroke. An embolic stroke occurs when a blood clot or other debris
forms away from your brain — commonly in your heart — and is swept
through your bloodstream to lodge in narrower brain arteries. This type of
blood clot is called an embolus.
Ways it can be prevented
Eating a healthy diet
Working out 2 or more days a
week
Restrict tobacco use
Restrict alcohol use
Controlling other diseases
Be aware of age, family history,
race, ethnicity, and previous
stroke history
Treatments
-Anticoagulant medicines
such as warfarin, prevents blood
clots and current clots from getting
bigger
-Antiplatelet medication, such as aspirin
(keeps platelets from sticking together)
-Thins out the blood
-Mechanical devices, surgical clips, or coils
