STROKE 2
Stroke
A stroke is a medical condition that is associated with the brain. The Khan Academy (n.d)
describes stroke as a condition that results from the disruption of blood supply to the brain that
results in the limitation/loss of functionality of the brain or a portion of it. Stroke has several
symptoms. Some of these include sudden numbness (mostly on one side of the body), trouble
speaking/understanding speech, sudden confusion, sudden trouble walking, lack of coordination,
dizziness, loss of balance, and sudden eyesight problems (Bendok & Bendok, 2012). A stroke's
effects depend on the blood vessels that are affected, the part of the brain that is affected, and the
severity of brain damage. Because the left side of the brain controls the right side of the body, a
stroke on the left side of the brain will lead to limited or loss of functionality on the right side of
the body (Hedna et al., 2013). Speech and language are also affected.
A transient ischemic attack (TIA) differs considerably from a stroke. The TIA is a
temporary stroke that often shares its similarities with a stroke, but whose symptoms disappear
within 24 hours without permanent damage to the brain cells (Khan Academy, 2020). The effects
of TIA are reversible. Stroke also occurs in the form of ischemic or hemorrhagic stroke. Ischemic
stroke occurs when blood supply to the brain is blocked, often due to blood clots or gradual
constriction of blood vessels (as is the case with atherosclerosis patients) (Khan Academy, 2020).
This often affects parts of the brain that was supplied with blood by the blocked vessel. On the
other hand, hemorrhagic stroke results from a rupture of blood vessels (Bendok & Bendok, 2012).
Other than disrupting the blood supply downstream, the section of the brain surrounding the point
of rupture is also affected. Ischemic stroke is easily managed through medication to break down
blood clots, exercise, quitting alcohol/smoking, exercise, and healthy diets (Bendok & Bendok,
2012). However, hemorrhagic stroke is best managed through surgery to prevent blood leakage in
the brain.
