Transient global amnesia (TGA) is a rare symptom complex characterized by a brief episode of severe fixation, anterograde and retrograde amnesia. The prevalence of TGA increases with age.

An "Engram-Centric" Approach to Transient Global Amnesia (TGA) and Other Acute-Onset Amnesias. [PDF]
The differential diagnosis of acute-onset amnesia includes transient global amnesia (TGA), transient epileptic amnesia (TEA), and functional (or psychogenic) amnesia.

Case reports over the past 100 years have raised the possibility that epilepsy can manifest itself in episodes of amnesia. Recent research has established that this is indeed the case, and indicates that characteristic varieties of interictal memory disturbance co-occur with this form of epilepsy.Transient epileptic amnesia is a distinctive syndrome of

Recurrent amnesia caused by early seizures after hippocampal infarction: a case report
Background We report the case of a patient with recurrent episodes of disturbed memory suggestive of transient epileptic amnesia, and a focal hippocampal lesion typically associated with transient global amnesia.

Transient epileptic amnesia (TEA) is a rare epileptic condition, often confused with transient global amnesia (TGA). In a real-life scenario, differential diagnosis between these two conditions can be hard.

We report a patient presenting with episodes of transient amnesia, some with features suggestive of transient global amnesia (TGA), and some more reminiscent of transient epileptic amnesia.

Transient epileptic amnesia and transient global amnesia both exhibit temporary memory loss. The lack of clues of epileptic events and the absence of epileptiform abnormalities in electroencephalography, a clear brain lesion, and interictal cognitive decline can make diagnoses challenging.

Postictal punctate hippocampal diffusion restriction: the chicken or the egg? [PDF]
IntroductionMagnet resonance imaging (MRI) is the imaging gold standard for the evaluation of suspected epileptic seizures but also indispensable for detecting cerebral ischemia, using diffusion-weighted imaging (DWI) sequences. DWI restrictions can also

Focal autobiographical amnesia in association with transient epileptic amnesia [PDF]
Although problems with remembering significant events from the past (e.g. holidays, weddings, etc.) have been reported previously in patients with transient epileptic amnesia (TEA), to date there have been no detailed studies of autobiographical memory in patients with this disorder.

Autobiographical amnesia and accelerated forgetting in transient epileptic amnesia [PDF]
Recurrent brief isolated episodes of amnesia associated with epileptiform discharges on EEG recordings have been interpreted as a distinct entity termed transient epileptic amnesia (TEA). Patients with TEA often complain of autobiographical amnesia for recent and remote events, but show normal anterograde memory.To investigate (a) accelerated long term
