Transient Global Amnesia After Cerebral Angiography

Transient Global Amnesia After Cerebral Angiography With Iomeprol

“…Several authors have favored a direct neurotoxic effect of the contrast media as the causative factor leading to transient global amnesia after cerebral angiography. 9 , 11 , 12 This complication has been observed with both ionic and nonionic contrast agents, being reported 3 times as prevalent using the former. 20 Due to their hyperosmolality, contrast agents are considered to have neurotoxic effects by temporarily disrupting the blood–brain barrier with subsequent parenchymal penetration.…”

Transient global amnesia after cerebral angiography still occurs: Case report and literature review

“…Others have indicated contrast-agent neurotoxicity as a causative factor of TGA ( 12 , 21 ). TGA has been observed with both nonionic and ionic contrast agents, and reported three times as prevalent using the latter ( 18 , 22 ).…”

Transient global amnesia and transient ischemic attack: a community-based case-control study

“…An epileptic origin has been advocated by other authors (36)(37)(38)(39)(40). Furthermore, TGA has been described to occur in several different clinical settings (41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57) and its onset has been related to various possible precipitating conditions, in particular stressful events (10,13,15,(17)(18)(19).…”
