We report a patient presenting with episodes of transient amnesia, some with features suggestive of transient global amnesia (TGA), and some more reminiscent of transient epileptic amnesia. Investigation with neuroimaging revealed an intrinsic lesion in the right amygdala, with features suggestive of low-grade neoplasia. We undertook a systematic review of the literature on TGA and brain tumour...

The influence of extractive content on the thermal stability and kinetic degradation of two wood species has been investigated using chemical analysis and thermogravimetry. Two wood species were studied: Pinus taeda and Eucalyptus grandis. Thermogravimetric results showed that higher extractive contents in the wood accelerate the degradation process and promote an increase in the conversion val...

Transient epileptic amnesia (TEA) is a seizure disorder characterized by brief, recurrent attacks of amnesia in middleaged or elderly subjects, often occurring on waking, with favorable response to anticonvulsant medication [1]. While this syndrome is becoming increasingly recognized, its association with transient global amnesia (TGA) is not fully understood. It remains unknown whether TEA is ...

BACKGROUND Transposition of the great arteries (TGA) is considered to be associated only rarely with genetic syndromes and to have a low risk of precurrence among relatives of affected patients. Because most family studies have involved a relatively small number of patients and evaluated all types of TGA as a single group, we performed a large, prospective study investigating the precurrence of...

A 54-year-old woman with transient global amnesia (TGA) was found to have digitalis-induced bradyarrhythmia with atrioventricular dissociation. The amnesia cleared only upon resolution of the arrhythmia. Cardiac arrhythmia has been postulated as a cause, but TGA in the setting of cardiac arrhythmia has not been documented previously. Cardiac arrhythmia should be excluded in patients with TGA, a...

BACKGROUND AND PURPOSE Transient global amnesia (TGA) has been associated with an increased prevalence of internal jugular valve insufficiency and many patients report Valsalva-associated maneuvers before TGA onset. These findings have led to the assumption of hemodynamic alterations in intracranial veins inducing focal hippocampal ischemia. We investigated this hypothesis in patients with TGA ...

Dear Editor, Transient global amnesia (TGA) is a syndrome characterized by sudden-onset transient amnesia that is not associated with other neurological deficits.1 Although the exact pathophysiology is not completely understood, emotional stress, physical exertion, temperature change, and sexual intercourse are common precipitating events of TGA.2 Keret et al.3 recently hypothesized that the in...

· The Therapeutic Goods Administration (TGA) is part of the Australian Government Department of Health and Ageing, and is responsible for regulating medicines and medical devices. · The TGA administers the Therapeutic Goods Act 1989 (the Act), applying a risk management approach designed to ensure therapeutic goods supplied in Australia meet acceptable standards of quality, safety and efficacy ...

Background. Transient global amnesia (TGA) is a syndrome of sudden, unexplained isolated short-term memory loss. In the majority of TGA cases, no causes can be identified and neuroimaging, CSF studies and EEG are usually normal. We present a patient with TGA associated with a small acute infarct at the cingulate gyrus. Case Report. The patient, a 62 year-old man, developed two episodes of TGA. ...

trans-Glutaconic acid (tGA) is an unsaturated C5-dicarboxylic acid which may be found accumulated in glutaric aciduria type I, whose pathophysiology is still uncertain. In the present work it was investigated the in vitro effect of increasing tGA concentrations on neurochemical and oxidative stress parameters in rat cerebral cortex. We observed that Na(+), K(+)-ATPase activity was reduced by tG...
