Understanding Strokes
Strokes are classified into three main types based on what causes the disruption in blood flow to the brain. Each type carries its own risks and treatment approaches.
Ischemic strokes occur when a clot blocks blood flow to part of the brain, accounting for nearly nine out of ten strokes. These often result from plaque buildup in arteries or clotting disorders.
Hemorrhagic strokes involve bleeding into or around the brain from a ruptured vessel. These can be caused by high blood pressure, aneurysms, or trauma.
Transient ischemic attacks (TIAs), or “mini-strokes,” are brief interruptions of blood flow that resolve within minutes. Though temporary, they are major red flags for a future, more serious stroke.
Risk factors include hypertension, smoking, high cholesterol, diabetes, atrial fibrillation, and a family history of stroke. Even lifestyle elements—like stress, alcohol use, and lack of physical activity—can tip the scales.
