Abstract

Transient global amnesia is a self-limited syndrome of sudden anterograde amnesia, variable retrograde amnesia, preserved personal identity, and recovery within 24 hours. It is well recognized in adults but rarely reported in children, where overlap with seizure, encephalitis, migraine, intoxication, concussion, and psychiatric or dissociative presentations complicates diagnosis. We describe a previously healthy 6-year-old girl who presented with acute confusion, repetitive speech, inability to retain new information, and impaired recall of same-day events. There were no focal neurologic deficits, impaired consciousness, epileptic features, toxic exposure, infection, metabolic disturbance, or psychiatric symptoms. Laboratory tests, cranial computed tomography, brain magnetic resonance imaging, and electroencephalography were normal. Complete recovery occurred within 16 hours. A low-impact head trauma on the day of admission was identified retrospectively and interpreted as a possible precipitant, although recent head injury limits strict application of adult diagnostic criteria. This case highlights pediatric transient amnestic syndromes as underrecognized diagnostic entities.
