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.

Transient global amnesia is a disorder characterized by an attack of temporary anterograde amnesia with no other focal neurological symptoms. 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. 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). With this clinical history and characteristic MRI findings, a diagnosis of transient global amnesia (TGA) was made.

2021-03-19 · 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. MRI brain was performed with a 3T scanner on 11 patients and 1.5T scanner on 1 patient.

2019-01-11 · Transient global amnesia (TGA) is a disorder characterised by a temporary, reversible disruption of short-term memory. While the diagnosis of TGA is based on its clinical features, neuroimaging is important to exclude other sinister causes of global amnesia. Furthermore, classical MRI changes in TGA have been well described in the liter-ature. A 12-lead ECG and haematological investigations were normal. We made a clinical diagnosis of transient global amnesia (TGA). Brain diffusion-weighted MRI at 48 h postevent showed focal bilateral medial temporal lobe high signal with restricted diffusion .
