Transient ischemic attack caused by delayed orthostatic hypotension in an elderly hypertensive patient.

Hypertension is the most powerful predictor of transient ischemic attack (TIA) and stroke. Thus, in order to avoid subsequent cerebrovascular episodes in patients with cerebral ischemia, it is crucial to lower blood pressure (BP) as a preventive measure. Orthostatic hypotension (OH), on the contrary, is considered a predisposing factor for cerebral generalized hypoperfusion rather than for cerebral focal ischemia. We show here a case of a 91-year-old woman with multiple TIA episodes that were triggered by an orthostatic fall in BP.
