Stroke & Vascular Disorders
A transient ischemic attack (TIA) is defined as an acute focal neurologic deficit that is localized to one vascular territory, lasting less than 24 hours, with abrupt onset and abrupt or gradual resolution. Carotid TIAs occur in the territory of the internal carotid artery or its branches. Symptoms of carotid TIAs include transient dysarthria, limb weakness, face weakness, visual impairment, dysphasia, and body or face numbness or paresthesia.
