Stroke, or "brain attack," occurs when blood flow to the brain is interrupted by a blockage (ischemic) or bleeding (hemorrhagic), causing brain cell death and potential long-term complications like paralysis or cognitive decline. Early recognition of symptoms (e.g., using the FAST acronym) and immediate medical intervention are critical. Advanced treatments, rehabilitation, and neurologist-led care improve recovery and reduce long-term impact.

Key Points on Stroke

Definition: Neurological emergency caused by blocked or ruptured blood vessels in the brain.
Types: Ischemic (clot-related), hemorrhagic (bleeding), transient ischemic attack (TIA), cryptogenic (unknown cause).
Symptoms: FAST (Face drooping, Arm weakness, Speech difficulty, Time to call emergency), severe headache, loss of balance, and paralysis.
Risk Factors: High blood pressure, diabetes, high cholesterol, smoking, obesity, and heart conditions.
Treatment: Thrombolysis, mechanical thrombectomy, cerebrovascular surgery, and rehabilitation therapies.
Prevention: Manage blood pressure, cholesterol, and lifestyle factors; recognize early symptoms and seek immediate care.
