Transient global amnesia and hippocampal foci of restricted diffusion.
To cite: Mallio CA, Assenza G, Occhicone F, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010154 DESCRIPTION A 63-year-old man was admitted owing to the onset upon awakening of anterograde amnesia and spatiotemporal disorientation accompanied by repetitive questioning. No disturbances of consciousness and self-awareness or others focal neurological sy...
متن کاملTransient global amnesia--a hippocampal phenomenon?
A case of transient global amnesia of clear vascular aetiology is described. Results of neuropsychological testing carried out during the attack clarify the nature of the memory disorder and suggest that the critical region of ischaemia is the medial temporal area around the hippocampus. Follow-up testing suggests that no lasting memory impairment resulted.
متن کاملTransient Hyperintensity On Diffusion-Weighted MRI in Transient Global Amnesia
Objects: Different theories were suggested on the etiopathogenesis of transient global amnesia. Methods: We demonstrate a patient with transient global amnesia, in whom, a transient hyperintense signal change on left hippocampus was detected in diffusionand T2weighted magnetic resonance images. Conclusion: The absence of vascular risk factors or atherosclerotic changes in neuroimaging, in addit...
متن کاملBilateral hippocampal abnormalities on diffusion-weighted MRI in transient global amnesia: report of a case.
The pathophysiology of transient global amnesia (TGA) is still speculative. Recently, diffusion-weighted image (DWI) of magnetic resonance imaging (MRI) documented tiny lesions in the hippocampus of patients with TGA in the acute stage. Most studies reported unilateral lesions on MRI. We present one patient of TGA with high signal-intensity lesions in bilateral hippocampus on DWI at the acute s...
متن کاملTransient global amnesia or transient epileptic amnesia?
Sir, We read with great interest the letter of McCorry and Crowley concerning an attack of transient global amnesia (TGA) considered secondary to herpes simplex viral encephalitis. Some features of the reported attack are unusual. The patient was a relatively young person: 39 years compared with an average age of 61 with TGA. At the beginning the patient suddenly became ‘distressed’; he realize...
