Transient Global Amnesia: A Case Report

Abstract

Introduction: Transient global amnesia is a syndrome of temporary and reversible disruption of short-term memory accompanied by repetitive questioning. Although the etiology is unknown, the prognosis usually benign, and no particular treatment is required, it is important for all involved clinicians to recognize the diagnosis and possess knowledge about the evaluation of these affected patients. Case Presentation: A middle-aged Caucasian woman presented for neurologic evaluation for acute forgetfulness. Neurologic examination disclosed repetitive questioning with preserved orientation and no focal motor, speech, sensory, coordination, or cranial nerve deficits. Neurologic investigations did not reveal any pathologic findings. Her memory improved and reverted to normal baseline over the course of a 24-hour hospital stay. Conclusion: Transient global amnesia is an interesting syndrome of reversible anterograde amnesia associated with repetitive questioning that occurs with an unclear etiology in middle-aged and elderly individuals. Due clinical diligence is required in the investigation of these patients. Treatment is generally not required, and the condition usually does not recur. Clinicians, including neurologists, internists, family practice physicians, and psychiatrists, need awareness of this condition.

Transient Global Amnesia, an Uncommon Diagnosis of Exclusion

“…Most of the cases of TGA are seen in middle-aged and elderly people. The incidence of TGA among those less than 50 years old is estimated at 23 to 32 per 100,000 each year [11] .…”

“…The incidence of TGA among those less than 50 years old is estimated at 23-32 per 100,000 each year. 11 There is no known etiology for TGA. Known risk factors for stroke, such as hypertension, diabetes mellitus, smoking, and hypercholesterolemia, are not associated with TGA, while migraines have been found to be highly associated with TGA.…”

“…Hasta, çoğu zaman amnestik durum geliştikten sonraki yeni bilgileri kayıt edemez (anterograd amnezi) ancak bazen de önceki yakın olayları hatırlayamaz (retrograd amnezi) (5). Fokal nörolojik defisitin gözlenmediği TGA atağı 24 saatten kısa sürer (6). Ani sıcak veya soğuk suya dalmalar, yoğun ağrı veya emosyonel stres, cinsel ilişki, valsalva manevrası ile birlikte ağır fiziksel aktivite TGA hastalarında tetikleyici faktörler olarak tanımlanmıştır (7).…”
