Transient neurologic events with focal signs (i.e., hemiparesis, dysarthria, or amaurosis fugax) are traditionally called transient ischemic attacks (TIAs) and are associated with high risk for stroke (in some studies, roughly 10% in the subsequent 3 months). However, some patients experience nonfocal neurologic symptoms (e.g., disturbances of consciousness, amnesia, unsteadiness, or dizziness) that appear suddenly, are transient, and cannot be explained by conditions such as cardiac arrhythmias, seizures, or orthostatic hypotension. In this population-based cohort study, Dutch researchers determined the incidence and prognosis of these so-called “nonfocal transient neurologic attacks” among 6000 people (age ≥55) with no history of stroke, …
