Transient Ischemic Attack (TIA)

Transient ischemic attack (TIA) is transient focal neurologic dysfunction from cerebral/retinal ischemia without infarction. Symptoms: sudden unilateral weakness/numbness, speech disturbance, or monocular vision loss, resolving within minutes to hours. It is a major warning of impending stroke. Workup: urgent neuroimaging and vascular/cardiac evaluation. Treatment: antiplatelet therapy, control vascular risk factors (BP/lipids/diabetes/smoking), carotid revascularization when indicated.

Common Symptoms

Sudden unilateral weakness/numbness; speech disturbance; monocular vision loss; resolves within minutes-hours

Causes and Pathogenesis

Thromboembolic/hemodynamic cerebral ischemia produces transient focal deficits without completed infarction.

Treatment

Antiplatelet; control vascular risk; carotid revascularization when indicated; urgent workup

Preventive Measures

Control vascular risk; antiplatelet; urgent TIA evaluation; lifestyle.
