Transient global amnesia (TGA) is characterized by an attack of temporary antero- grade amnesia without other focal neurological deficits. Characteristic magnetic resonance imaging (MRI) findings include small, punctate, unilateral or bilateral diffusion restriction in the lateral aspect of the hippocampus, which mostly occurs within 48 hours after symptoms onset.

DWI—ideally performed with a minimum delay of 20 hours after onset—should therefore be considered a useful adjunct to the diagnosis of TGA. Transient global amnesia (TGA) is characterized by an attack of temporary antero-grade amnesia without other focal neurological deﬁ cits. Characteristic magnetic resonance imaging (MRI) ﬁ ndings include small, punctate, unilateral or bilateral diffusion restriction in the lateral aspect of the hippocampus, which mostly occurs Transient global amnesia: hippocampal magnetic resonance imaging abnormalities Transient global amnesia (TGA) is an episodic dysfunction of declarative memory that usually resolves within 12 hours and whose underlying pathophysiological mechanisms are still unclear. Patienter med transitorisk global amnesi (TGA) kan påträffas inom alla specialiteter, men kanske främst på en medicinsk akutmottagning eller vårdcentral. TGA karakteriseras av en tillfällig, akut insättande oförmåga att inprägla och behålla minnen, vilket varar mellan 2 och 3 upp till 24 timmar [1-3]. Se hela listan på janusinfo.se Both TGA and anterograde amnesia deal with disruptions of short-term memory. However, a TGA episode generally lasts no more than 2 to 8 hours before the patient returns to normal with the ability to form new memories.

7–10 With the herald of nonionic 2020-06-05 2015-03-24 Transient global amnesia (TGA) is a clinical syndrome with no clear etiology identified. 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.
