Summary

An ischemic_stroke happens when an arterial_blockage stops blood flow to brain tissue, usually from a thrombus_or_embolus. It is the most_common_stroke type. Expect sudden focal_neurologic_deficits like facial droop, arm weakness, or speech trouble; remember the FAST_signs. Care is time_sensitive, because time_is_brain. Major risk_factors include hypertension, atrial_fibrillation, diabetes, smoking, and high cholesterol. Initial imaging typically uses a CT_scan to exclude hemorrhage. Key goal is quick recognition and prompt evaluation.
