Background: Transient global amnesia (TGA) is a clinically amnestic syndrome characterized by normal neurological function aside from sudden-onset, reversible anterograde amnesia during the episode. TGA is typically related to strenuous physical activity, severe emotional stress and some medical procedures, such as angiography, while reports of TGA related to gastrointestinal (GI) endoscopy are...
Transposition of the great arteries or TGA is a potentially fatal congenital heart malformation where the pulmonary artery and the aorta are switched. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood. There are two types of the malformation, d-TGA where no oxygen reaches the body and l-TGA where some oxygenated blood circulates. In the US, the...

the kinetics of molybdenite oxidation was studied by non-isothermal tga-dta with heating rate 5 ºc.min-1.the model-fitting kinetic approach applied to tga data .the coats-redfern method used for model fitting. the popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. the apparent activation energy was determined to be about 34.2 kcalmol-1 with pre-ex...
Transposition of great arteries (TGA) is one of the most common and severe congenital heart diseases (CHD). It is also one of the most mysterious CHD because it has no precedent in phylogenetic and ontogenetic development, it does not represent an alternative physiological model of blood circulation and its etiology and morphogenesis are still largely unknown. However, recent epidemiologic, exp...
To evaluate risk factors and prognosis of transient global amnesia (TGA), three groups of 30 subjects each affected respectively by: (1) first-ever TGA; (2) first-ever transient ischaemic attack (TIA); (3) depressive neurosis, were compared. Prevalence of cerebrovascular risk factors was similar in patients with TGA and TIA, but significantly lower in the third group. CT showed more hypodense l...
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...
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...
