Clinically, it manifests with a paroxysmal, transient loss of memory function. Immediate recall ability is preserved, as is remote memory; however, patients experience striking loss of memory for recent events and an impaired ability to retain new information. Transient global amnesia is anterograde and usually retrograde amnesia that begins suddenly and lasts up to 24 hours. Diagnosis is primarily clinical but includes laboratory tests and CT, MRI, or both. The amnesia typically remits spontaneously but may recur. There is no specific treatment, but underlying abnormalities are corrected. MRI findings.

Epidemiology Most common in patients of older age (50-70 years old). MRI Findings in Transient Global Amnesia T ransient global amnesia (TGA) is a disorder characterized by a sudden attack of severe anterograde amnesia, where patients are unable to learn and recall novel information during the event. Although fi rst described at least 60 years ago,1 the etiology and pathophysiology of TGA remain unclear and have 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.

Winbeck K, Etgen T, von Einsiedel HG, et al. DWI in transient global amnesia and TIA: proposal for an ischaemic origin of TGA. 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 and has difficulty recalling recent memories. 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.

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 .
