To be consistent with a diagnosis of TIA or stroke, a focal neurologic deficit must have occurred suddenly. The differential diagnosis of TIA includes migraine aura (possibly without a headache), a hypotensive episode, radiculopathy, and an unusual seizure. Vascular risk factors (eg, hypertension, diabetes, smoking) and the extent of their control should be determined. Cardiac examination and ECG may provide important clues, as atrial fibrillation and valvular heart disorders are well recognized potential sources of emboli. During an acute stroke, CT is the best test to reliably distinguish between ischemic and hemorrhagic stroke. Other tests that may be indicated on an individual basis include MRI, echocardiography, carotid duplex ultrasound, and arteriography.
