The pregnant female human angiotensinogen (hAGN) transgenic rat mated with the male human renin (hREN) transgenic rat is a model of preeclampsia (TgA) with increased blood pressure, proteinuria, and placenta alterations of edema and necrosis at late gestation. We studied vascular responses and the role of COX-derived prostanoids in the uterine artery (UA) at early gestation in this model. TgA U...

Transient global amnesia (TGA) is usually considered to produce a profound impairment of long-term episodic memory, while at the same time sparing working memory. However, this neuropsychological dissociation has rarely been examined in detail. While a few studies have assessed some components of working memory in TGA, the results that have been obtained are far from conclusive. To clarify this...

BACKGROUND AND PURPOSE A hypoxic-ischemic origin of transient global amnesia (TGA) has been suggested on the basis of the observation of infarctlike diffusion-weighted imaging (DWI) abnormalities in some affected individuals. We tested this hypothesis by comparing vascular risk factors, magnetic resonance imaging (MRI) markers of cerebral small-vessel disease, and other evidence of a cerebrovas...

29 The pregnant female human angiotensinogen (hAGN) transgenic rat mated with the male 30 human renin (hREN) transgenic rat (TgA) is a model of preeclampsia with increased blood 31 pressure, proteinuria, and placenta alterations of edema and necrosis at late gestation. We 32 studied vascular responses and the role of COX-derived prostanoids in the uterine artery 33 (UA) at early gestation in th...

The integrity of temporal lobe activity during and after recovery from transient global amnesia (TGA) was assessed in a case study using functional MRI. TGA was associated with scene-encoding deficits in a temporolimbic circuit that recovered over time. Frontoparietal areas recruited during the amnesic state may signify a compensatory reliance on visuospatial or working memory strategies. Reduc...

Transient global amnesia (TGA) is a disorder characterized by a sudden attack of severe anterograde amnesia, where patients are unable to learn and recall novel information during the event. Although fi rst described at least 60 years ago, the etiology and pathophysiology of TGA remain unclear and have been a matter of debate among clinicians and researchers. In this paper, we present a case of...

BACKGROUND Recently a causal relation between internal jugular vein valve incompetence (IJVVI) and transient global amnesia (TGA) has been suggested. IJVVI is postulated to provoke a transient mesiotemporal ischaemia by venous congestion. This mechanism requires a patent venous pathway from the affected IJV through the transverse sinus, confluens, straight sinus (SS), vein of Galen into the bas...

Transient global amnesia (TGA) is a temporary disease with an unexplained aetiology. The clinical picture of TGA is characterised by retrograde amnesia (spanning from several days to several years), anterograde amnesia (from few to several hours, most often from 4 to 8), significant disorientation with respect to time (about 50% of the patients) and place (above 90% patients), preserved auto-or...

The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA) amongst patients with type 1 diabetes (T1D) and autoimmune thyroid disease (AITD) in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and...

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...
