Transient Cerebral Ischemic Attack

Transient ischemic attack (TIA) is a transient episode of focal neurologic dysfunction caused by focal brain/retinal ischemia, without acute infarction. Symptoms (weakness/speech/vision loss) typically resolve within minutes to hours. It is a warning of impending stroke. Workup: urgent brain/neurovascular imaging, ECG/holter, and vascular risk assessment. Treatment: antiplatelet therapy, control vascular risk factors (BP/lipids/diabetes/smoking), carotid revascularization when indicated, and lifestyle modification.

Common Symptoms

Transient unilateral weakness/numbness; speech disturbance; monocular vision loss; symptoms resolve within minutes-hours

Causes and Pathogenesis

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

Treatment

Antiplatelet; control vascular risk (BP/lipids/diabetes/smoking); carotid revascularization when indicated; lifestyle

Preventive Measures

Control vascular risk; antiplatelet; urgent TIA workup; lifestyle modification.
