Ischemic Evidence of Transient Global Amnesia: Location of the Lesion in the Hippocampus
BACKGROUND AND PURPOSE Transient global amnesia (TGA) is a rare amnestic syndrome characterized by the sudden onset of a selective anterograde and retrograde amnesia with a time course of up to 24 hours. Recent studies have found a high frequency of small high-signal abnormalities in the hippocampus on diffusion-weighted imaging (DWI), and accordingly ischemia has been proposed as an etiology o...
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 کاملEffect of Coenzyme Q10 (ubiquinone) on hippocampal CA1 pyramidal cells following transient global ischemia/reperfusion in male wistar rat
Ischemia/Reperfusion (I/R)-induced cerebral injury has been reported as a leading cause of deathand long-term disabilities. Hippocampus is an area which is more sensitive to be affected by I/Rand hypoxic conditions. Coenzyme Q10 is a strong antioxidant which plays a role in membranestabilization. This study aims to investigate the possible role of CoQ10 in ameliorating thehistomorphological cha...
متن کاملProtective effect of α-terpineol against impairment of hippocampal synaptic plasticity and spatial memory following transient cerebral ischemia in rats
Objective(s): Cerebral ischemia is often associated with cognitive impairment. Oxidative stress has a crucial role in the memory deficit following ischemia/reperfusion injury. α-Terpineol is a monoterpenoid with anti-inflammatory and antioxidant effects. This study was carried out to investigate the effect of α-terpineol against memory impairment following cerebral ischemia in rats. Materials a...
متن کاملLesions of the hippocampal formation but not lesions of the fornix or the mammillary nuclei produce long-lasting memory impairment in monkeys.
A group of tasks sensitive to human amnesia were used to characterize the severity and duration of memory impairment in monkeys following bilateral damage to the hippocampal formation, fornix, or mammillary nuclei. Monkeys with hippocampal formation lesions (which included the hippocampus proper, dentate gyrus, subiculum, posterior entorhinal cortex, and much of the parahippocampal gyrus) exhib...
