What is Stroke?

Stroke is a medical emergency that occurs when the blood supply to part of the brain is suddenly interrupted or severely reduced, depriving brain tissue of oxygen and nutrients and causing brain cells to begin dying within minutes. It is broadly classified into ischemic stroke, caused by a blood clot blocking an artery supplying the brain, which accounts for the majority of cases, and hemorrhagic stroke, caused by a blood vessel rupturing and bleeding into or around the brain. The specific symptoms and their severity depend on which part of the brain is affected and how much tissue is deprived of blood flow, and permanent disability or death can result if blood flow is not restored quickly. Because brain tissue is lost rapidly with every passing minute, immediate recognition of symptoms and emergency treatment are critical to minimizing permanent damage.

Causes of Stroke

Ischemic stroke most commonly results from a blood clot that forms within a narrowed artery due to atherosclerosis, or a clot that travels from elsewhere in the body, such as the heart in people with atrial fibrillation, and lodges in a brain artery. Hemorrhagic stroke results from the rupture of a weakened blood vessel, often due to chronic high blood pressure or an aneurysm, causing bleeding directly into brain tissue. Major risk factors for stroke overall include high blood pressure, diabetes, high cholesterol, smoking, atrial fibrillation, and a sedentary lifestyle.

Symptoms of Stroke

sudden weakness or numbness of the face, arm, or leg especially on one side of the body, sudden confusion or trouble understanding speech, sudden difficulty speaking or slurred speech, sudden vision problems in one or both eyes, sudden severe headache with no known cause, sudden difficulty walking, dizziness, or loss of balance and coordination

Treatment & Types of Stroke in Arga, Shivamogga, Karnataka

For ischemic stroke, rapid administration of clot-dissolving medication within a narrow time window from symptom onset, or mechanical removal of the clot through a catheter-based procedure called thrombectomy, can restore blood flow and significantly reduce disability. Hemorrhagic stroke management focuses on controlling blood pressure, reversing any blood-thinning medications, and in some cases surgical intervention to relieve pressure or repair the bleeding vessel. Following the acute phase, comprehensive stroke rehabilitation involving physical, occupational, and speech therapy is essential to maximize functional recovery.

Stroke is broadly classified into ischemic stroke, caused by a blood clot blocking an artery supplying the brain and accounting for the majority of cases, and hemorrhagic stroke, caused by a ruptured blood vessel bleeding into or around the brain. Ischemic stroke is further divided by mechanism into thrombotic, from a clot forming locally in a narrowed artery due to atherosclerosis, and embolic, from a clot traveling from elsewhere, such as the heart in atrial fibrillation; a transient ischemic attack, sometimes called a mini-stroke, involves the same blockage mechanism but with symptoms resolving completely within 24 hours and still warrants urgent evaluation.
