Introduction: Aim of this study is to identify and describe the MRI findings in patients with Transient Global Amnesia (TGA), specifically on Diffusion Weighted Imaging (DWI) sequence. Methods: MRI findings in 12 patients with clinical diagnosis of TGA were retrospectively analysed. The detection rate of diffusion-weighted (DWI) hyperintense lesions varies widely in patients with transient global amnesia (TGA). The aim was to examine the association of hyperintense lesions on DWI magnetic resonance imaging (MRI) with patient characteristics, precipitating factors, clinical presentation and MRI settings in patients with TGA. Se hela listan på de.wikipedia.org Die transiente globale Amnesie (TGA) ist durch eine akut einsetzende Störung aller Gedächtnisinhalte (visuell, taktil, verbal) für einen Zeitraum von 1 bis maximal 24 Stunden, bei im Mittel 6–8 Stunden gekennzeichnet. Während der Attacke ist die Behaltensspanne für neue Informationen auf 30–180 Sekunden reduziert (anterograde Amnesie). Transient global amnesia (TGA) is clinically defined as sudden onset anterograde amnesia with preserved alertness, attention, and personal identity, which occurs during a period of no more than 24 hours with no long-term sequelae. 1–3 The incidence of TGA has been reported to be 5–11 per 100,000 persons per annum.

However, in 1882 and 1909, Ribot 3 and Benon 4 had already described transient amnestic states suggestive of a TGA. 5 In 1964, Fisher and Adams 6 published a large case series and introduced the term as used today.

Most symptoms are transient and resolve within a few hours. Epidemiology Most common in patients of older age (50-70 years old). Introduction: Aim of this study is to identify and describe the MRI findings in patients with Transient Global Amnesia (TGA), specifically on Diffusion Weighted Imaging (DWI) sequence. Methods: MRI findings in 12 patients with clinical diagnosis of TGA were retrospectively analysed. CONCLUSIONS: The MRI protocol in patients with TGA should include a DWI sequence with a slice thickness of 3 mm or less. The examination should be performed on day 2 after symptom onset to fully exploit the diagnostic value of DWI which represents a sensitive and specific diagnostic tool for patients with TGA.

2018-01-01 2005-03-01 BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is characterized by sudden anterograde and retrograde amnesia lasting for up to 24 hours. Diffusion-weighted magnetic resonance imaging (DWI) in cases of TGA and ischemia demonstrates a high frequency of high signal intensities restricted to the hippocampus, and this has Transient global amnesia (TGA) is a rare medical condition in which a person experiences a sudden episode of memory loss. During a TGA episode, a person cannot form new memories (a condition called anterograde amnesia) and has difficulty recalling recent memories (a … 2010-02-01 2019-01-11 2018-12-11 2018-07-27 2021-03-19 We present the case of an elderly male who was diagnosed with transient global amnesia (TGA), only to be diagnosed with B-cell lymphoma with central nervous system involvement a few weeks later.

Diffusion-weighted imaging (DWI) represents a highly specific diagnostic tool in the context of TGA; however, standard clinical DWI often fails to detect the small characteristic Background Transient global amnesia is a well-described complication of cerebral angiography. Speculation about the pathophysiology exists but is as yet unsubstantiated. Diffusion-weighted MRI is a new imaging technique that is very sensitive in detecting acute ischemia. Magnetic resonance imaging (MRI) of the brain performed 48 h after the onset of symptoms demonstrated focal dot-like diffusion restriction in the right and left hippocampi (Figure 1).
