We report a patient with a generalized frontal-predominant nonconvulsive status epilepticus without clinically apparent altered consciousness. The patient was examined and EEG performed during and after the episode. Severe retrograde and anterograde amnesia during the seizure, contrasting with a preservation of ongoing memories formation that could be assessed only after its resolution, suggests a transient disconnection of access to stored mnesic representations. This unusual memory disorder…

A case of transient epileptic amnesia with radiological localization

A 54-year-old man presented to a cognitive disorders clinic having experienced recurrent episodes of transient amnesia over a number of years, with a gradual deterioration in his recall of remote events, despite normal performance on standard memory tests.

Syndromes of transient amnesia

Transient global amnesia or transient epileptic amnesia?

The patient was a relatively young person: 39 years compared with an average age of 61 with TGA; he suddenly became ‘distressed’; he realized the change and left office; the EEG performed on the second day exhibited right temporal sharp waves.

A case of long-lasting but reversible isolated amnesia of unknown aetiology

The patient appeared appropriately orientated, according to the medical staff and his family, although memory tests remained abnormal, and anti-epileptic treatment was administered, and the memory deficit lasted similar to 3 months but was followed by complete recovery.

The syndrome of transient epileptic amnesia: a combined series of 115 cases and literature review

It is concluded that transient epileptic amnesia is a distinctive syndrome of late-onset limbic epilepsy of unknown cause, typically occurring in late middle age, and is an important, treatable cause of memory loss in older people.

Transient epileptic amnesia is an under-recognized but treatable cause of transient memory impairment and accelerated long-term forgetting and autobiographical amnesia, which are invisible to standard memory tests, help to explain the discrepancy between normal test performance and prominent memory complaints among patients with epilepsy.

Pure transient amnesia during nonconvulsive status epilepticus.

A patient who, during nonconvulsive status, could not perform memory tasks (recall memory), but who nevertheless encoded events into long-term memory is described, which would seem to support Vuilleumier et al.'s hypothesis of a disassociation between these two memory tasks.

The two patients’ neuropsychological symptoms—visual object agnosia and cortical deafness—were associated with focal nonconvulsive status epilepticus and were successfully treated with anti-epileptic medications.

Absence status (petit mal status) with focal characteristics.

Two patients, aged 23 and 74 years, manifested prolonged episodes of mildly impaired consciousness in conjunction with rhythmical spike waves or spikes (mostly 3/s). This paroxysmal EEG activity was

Transient Global Amnesia as a Postictal State from Recurrent Partial Seizures

It is suggested that “epileptic” transient global amnesia is postictal in nature.

Epileptic Amnesic Syndrome

It is suggested that an epileptic origin be entertained in patients presenting repeated amnesic attacks resembling TGA or who complain of persistent memory disturbance, after more common etiologies have been excluded.

Epileptic amnesic attacks

Two sexagenarians who had recurrent circumscribed attacks of amnesia showed frequent bilateral spikes that arose independently from the temporal lobes, primarily from mesiobasal structures, and these attacks ceased after treatment with antiepileptic drugs.

Memory during subclinical hippocampal seizures

The rapidity of recall of a well-learned word list was impaired in 1 subject during ictal fast spiking in the left hippocampus, which may be responsible for a portion of the memory deficits found in patients with epilepsy.

In patients with evidence for bilateral MT dysfunction, a unilateral seizure may presumably suffice to induce a PAS, the contralateral MT structures being unable to ensure normal memory function.

Prolonged Ictal Amnesia with Transient Focal Abnormalities on Magnetic Resonance Imaging

A previously healthy woman had a prolonged amnestic state caused by complex partial status epilepticus with bilateral mesiotemporal lobe involvement confirmed by EEG with nasopharyngeal electrodes with reversible focal abnormalities consisting of increased signal intensity on T2‐weighted scan in the mesiotmporal lobe.

Transient partial amnesia.

A patient struck with transient amnesia was able to write a detailed account of her experiences during the episode and retained partial memory of the event, allowing an unusual view of transient partial amnesia.
