Aivoverenkiertohäiriöihin

Aivoverenkiertohäiriöihin, commonly known as stroke, refers to a sudden disruption of blood flow to the brain. This interruption can occur in two primary ways: ischemic stroke, where a blood clot blocks an artery supplying blood to the brain, or hemorrhagic stroke, where a blood vessel in the brain ruptures, causing bleeding. Ischemic strokes are more common, accounting for approximately 85% of all cases. Risk factors for stroke include high blood pressure, diabetes, high cholesterol, smoking, obesity, and a history of previous strokes or transient ischemic attacks (TIAs). Age and family history also play a role.

Symptoms of a stroke can vary depending on the area of the brain affected and the severity of the disruption. However, common signs include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body; sudden confusion or trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, or loss of balance or coordination; and sudden severe headache with no known cause. Recognizing these symptoms is crucial, as prompt medical attention can significantly improve outcomes.

Treatment for stroke depends on the type and cause. For ischemic strokes, clot-busting medications or mechanical thrombectomy may be used to restore blood flow. Hemorrhagic strokes may require surgery to stop the bleeding or relieve pressure on the brain. Rehabilitation, including physical, occupational, and speech therapy, is a vital part of recovery to help individuals regain lost functions. Prevention strategies focus on managing modifiable risk factors through lifestyle changes and medical interventions.
