Recent studies showed that the characteristic MRI findings of this disorder are small punctuate diffusion restricted lesions in the CA1 area of the hippocampal formation. 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. Recent studies, on the basis of transient focal high-signal abnormalities in the hippocampus on diffusion-weight … Key Words: transient global amnesia amnestic syndrome magnetic resonance imaging diffusion-weighted imaging risk factors T ransient global amnesia (TGA) is characterized by an-terograde memory disturbance of sudden onset that lasts for 1 to 24 hours.1 Orientation in space and time is impaired while consciousness remains undisturbed. From a defined Transient global amnesia is a sudden, temporary episode of memory loss that can't be attributed to a more common neurological condition, such as epilepsy or stroke. During an episode of transient global amnesia, your recall of recent events simply vanishes, so you can't remember where you are or how you got there. PURPOSE: Patients with transient global amnesia (TGA) present with a characteristic clinical syndrome although other differential diagnoses have to be considered.

We evaluated clinical history, family history and magnetic resonance diffusion-weighted imaging (DWI) studies of 93 Methods: MRI findings in 12 patients with clinical diagnosis of TGA were retrospectively analysed. MRI brain was performed with a 3T scanner on 11 patients and 1.5T scanner on 1 patient. DWI were Diffusion-weighted MRI may be useful in defining the pathophysiology.

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.

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. 2020-05-21 Transient global amnesia is now considered a very rare complication of cerebral angiography occurring in approximately 0.2% of the examinations performed with nonionic contrast media. 4 The first case of TGA after cerebral angiography was reported in 1981 by Wales and Nov. 6 During the following years, isolated cases and a number of series have been reported. 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.

TGA is a benign amnestic syndrome, usually lasting less than 24 h. It is characterised by a sudden onset of transient anterograde and retrograde amnesia without focal neurological signs or seizure features, and with other intellectual abilities preserved.

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.
