TGA measures the amount and rate (velocity) of change in the mass of a sample as a function of temperature or time in a controlled atmosphere. The measurements are used primarily to determine the thermal and/or oxidative stabilities of materials as well as their compositional properties. The technique can analyze materials that exhibit either mass loss or gain due to decomposition, oxidation or...

Transient global amnesia (TGA) is a dramatic event. Without warning, the patient suddenly experiences antegrade memory loss.1,2 As quickly as the amnesic syndrome appears, it resolves, usually within 24 hours. There are no apparent long-term sequelae, and recurrence is uncommon. What causes TGA? For years this question has been debated. Various proponents have advocated ischemic, migrainous, an...

The Mustard Operation is a surgical technique to correct a heart condition called the transposition of the great arteries (TGA). TGA is a birth defect in which the placement of the two arteries, the pulmonary artery, which supplies deoxygenated blood to the lungs, and the aorta, which takes oxygenated blood to the body are switched. William Thornton Mustard developed the operation later named f...

Transient global amnesia (TGA) is a well known clinical entity characterized by anterograde memory disturbance of sudden onset that lasts 1 to 24 hours. Orientation in space and time is impaired while consciousness remains undisturbed . TGA may refer to a single expression of several physiopathological phenomena. Conceptually, cerebral ischemia, epileptic discharge, and migraine constitute the ...

Transient global amnesia (TGA) is a neurological syndrome characterised by a self-limiting episode of isolated memory impairment. The aetiology of TGA is unknown but it is widely thought not to be an epileptic phenomenon. Nevertheless, epileptic seizures can cause a very similar clinical picture – the syndrome of transient epileptic amnesia (TEA). It is important to distinguish between these tw...

Objective This study evaluated alterations in cortical morphology in patients with transient global amnesia (TGA). Materials and Methods Diagnoses of TGA occurred at our hospital. Evaluation involved a structured interview to obtain clinical information and a brain magnetic resonance imaging scan. We analyzed whole-brain T1-weighted MRI data using FreeSurfer 5.1. Measures of cortical morpholo...
