Disturbance of venous flow patterns in patients with transient global amnesia

Internal Jugular Vein Valve Incompetence Is Highly Prevalent in Transient Global Amnesia

“…Our findings are similar to those reported by other authors using similar or other methods of evaluation. [17][18][19][20]22 In this prospective study, we followed standardized criteria for the assessment of patients with TGA and controls, and every subject was evaluated by an experienced neurologist.…”

Optimal Diffusion-Weighted Imaging Protocol for Lesion Detection in Transient Global Amnesia

“…This result concurred with the study by Sedlaczek et al, 9 in which the lesion-detection rate was 6% within 8 hours of onset and increased up to 84% at 48 hours after onset. The pathogenesis of TGA is uncertain, and various etiologic hypotheses have been proposed, including thromboembolism, 9,10 cerebral venous congestion induced by Valsalva-like activities, [18][19][20] and vasoconstriction caused by hyperventilation. 21 Whatever its etiology, several authors have suggested that delayed neuronal injury in the hippocampus is the cause of the delayed appearance of the lesions on DWI.…”

Hippocampal Ischemic Transient Global Amnesia after Gastrointestinal Endoscopy without Prior Medication

“…Published reports and hypotheses indicate that TGA could be caused by venous congestion accompanied by "Valsalva-like" activity [9,33,34]. Additionally, autonomic nervous system changes due to anxiety or rapid gastric dilation during the GI endoscopy procedure have been reported [35].…”
