Final answer:
The patient with pure motor hemiparesis likely has a lacunar stroke, which is a subtype of ischemic stroke characterized by the occlusion of small penetrative arteries affecting the brain's deep structures. Ischemic strokes need timely treatment with clot-busting drugs, whereas hemorrhagic strokes may require surgery to relieve pressure on the brain.
Step-by-step explanation:
The patient with pure motor hemiparesis is most likely experiencing a lacunar stroke. A lacunar stroke, which is a type of ischemic stroke, occurs when there is occlusion of one of the small penetrative arteries that provides blood to the brain's deep structures. It often results in specific types of strokes depending on the artery that is affected, and pure motor hemiparesis is a classic symptom observed in this kind of stroke. Ischemic strokes occur due to a lack of blood flow because of a blood clot in an artery going to the brain, and they are typically treated with a clot-busting drug to prevent permanent damage.
Hemorrhagic strokes, which represent about 10 percent of strokes and are often more fatal than ischemic strokes, occur due to bleeding from a broken blood vessel in the brain. Treatment for hemorrhagic strokes may include surgery to relieve the pressure in the brain. The symptoms of a stroke can include an inability to move or feel on one side of the body, difficulties with speech and understanding, confusion, and memory issues, and must be treated as a medical emergency to improve outcomes.
