Risk factors of Transient Global Amnesia

Migraine: Several case series and a meta-analysis have identified a higher risk of transient global amnesia among patients with migraine than among those without migraine.^[1]
Younger age at the first episode: In a retrospective series involving 1044 patients, younger age at the time of the first episode was associated with future episodes^[2].
Personal or family history of migraine: The same retrospective series suggested that a personal or family history of migraine presaged future episodes, although these findings have not been affirmed.^[2]
Cardiovascular risk factors: Cardiovascular risk factors have been overrepresented in some series but are probably commensurate with the typical age range of patients with transient global amnesia.^[3]
History of migraine in adolescents: Rare reports of transient global amnesia in adolescents have been linked to athletic activity and a history of migraine.^[4]
