PURPOSE: Transient Epileptic Amnesia (TEA) is a form of adult onset temporal lobe epilepsy characterised by ictal amnesia. The amnesic seizures are often accompanied by interical memory disturbance, involving autobiographical amnesia and accelerated long-term forgetting. Short-term follow-up studies suggest a relatively stable cognitive profile once treated, but recent case reports raise concerns regarding the risk of developing Alzheimer's disease (AD). The current study reports clinical and cognitive outcome in TEA patients over a 20-year period...

Neurological manifestations or disorders associated with central nervous system (CNS) are one of the most common as well as important clinical characteristics of antiphospholipid syndrome (APS). Although in the last updated (2006) classification criteria of APS its neurological manifestations encompassed only transient ischemic attack (TIA) and stroke, diverse 'non-criteria' neurological disorders or manifestations (headache, migraine, bipolar disorder, transverse myelitis, dementia, chorea, epileptic seizures, multiple sclerosis, psychosis, cognitive impairment, Tourette's syndrome, parkinsonism, dystonia, transient global amnesia, obsessive compulsive disorder and leukoencephalopathy) have been observed in APS patients...

Epilepsy with the main symptom of amnesia is known as transient epileptic amnesia (TEA). Dementia with Lewy bodies (DLB) is the second most common form of neurodegenerative dementia. The concept that Lewy body disease includes Parkinson's disease with dementia and dementia with Lewy bodies was proposed in the 2005 revision of the Clinical Diagnostic Criteria. Here, we describe a woman with cognitive impairment, olfactory dysfunction, and reduced (123) I-meta-iodobenzylguanidine uptake on myocardial scintigraphy...

A subtle behavioural or cognitive manifestation of epilepsy can be defined in two ways. First, epileptiform discharges not presenting as obvious seizures may nevertheless affect cognition and/or behaviour. Second, the actual seizures may be obvious but the way they affect cognition or behaviour may not be. There is a growing body of evidence indicating that the epileptiform discharges in benign epilepsy with centrotemporal spikes can affect behaviour and cognition. The focal discharges in other forms of epilepsy can also be associated with behavioural change...

Transient amnesia is one of common clinical phenomenon of epilepsy that are encountered by physicians. The amnestic attacks are often associated with persistent memory disturbances. Epilepsy is common among the elderly, with amnesia as a common symptom and convulsions relatively uncommon. Therefore, amnesia due to epilepsy can easily be misdiagnosed as dementia. The term 'transient epileptic amnesia (TEA)' was introduced in the early 1990s by Kapur, who highlighted that amnestic attacks caused by epilepsy can be similar to those occurring in 'transient global amnesia', but are distinguished by features brevity and recurrence...

To describe the association between Alzheimer's disease and seizures by reviewing epidemiological data from available literature and to assess the putative pathophysiological links between neurodegeneration and altered cortical excitability. We also discuss specific antiepileptic treatment strategies in patients with Alzheimer's disease, as well as transient epileptic amnesia as a possible crossroads between degeneration and epilepsy. Regarding epidemiology, we searched publications in Pubmed, Medline, Scopus and Web of Science (until September 2015) using the keywords "incidence", "prevalence" and "frequency", as well as "Alzheimer's disease" and "seizures"...

We describe a patient in whom long-term, therapeutic infusion of the selective gamma-amino-butyric acid type B (GABAB) receptor agonist, baclofen, into the cerebrospinal fluid (CSF) gave rise to three distinct varieties of memory impairment: i) repeated, short periods of severe global amnesia, ii) accelerated long-term forgetting (ALF), evident over intervals of days and iii) a loss of established autobiographical memories. This pattern of impairment has been reported in patients with temporal lobe epilepsy (TLE), in particular the subtype of Transient Epileptic Amnesia (TEA)...

Photodynamic therapy (PDT) is a commonly used and effective treatment option for nonmelanoma skin cancer. Apart from local side-effects such as pain, oedema and erythema, no major adverse events occur in the majority of cases. Here we report on five patients who developed memory deficits such as transient global amnesia immediately after PDT for actinic keratosis. All PDT treatments were performed according to standard therapy protocols. The reported patients had a memory gap for the entire procedure, as well as for the consecutive emergency medical care...

The year of 2014 is the birth centenary of Aristides Azevedo Pacheco Leão (1914-1993), and also marks seventy years of the publication of his discovery of the novel electrophysiological phenomenon, named by him "spreading depression" (SD), soon designated "Leão's wave" or "Leão's spreading depression". This was a remarkable scientific milestone, and the author must be celebrated for this achievement, as the studies he triggered proceeded worldwide, with new concepts, as spreading depolarization, until the present days...

Transient epileptic amnesia (TEA) is a presumably underdiagnosed syndrome belonging to the group of temporal lobe epilepsies. It can easily be misdiagnosed as transient global amnesia (TGA), transient ischaemic attack, psychogenic amnesia or even dementia. Many patients complain of loss of autobiographical memory and accelerated long-term forgetting. We present a case to emphasize both the importance of diagnosing TEA and the pitfalls between TEA and TGA syndrome.

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. Investigation with neuroimaging revealed an intrinsic lesion in the right amygdala, with features suggestive of low-grade neoplasia. We undertook a systematic review of the literature on TGA and brain tumour. Fewer than 20 cases were identified, some of which did not conform to the clinical diagnostic criteria for TGA. Hence, the concurrence of brain tumour and TGA is very rare and of doubtful aetiological relevance...

Transient global amnesia (TGA) is an acute and transient syndrome with a remarkably stereotypical set of signs and symptoms. It is characterized by the abrupt onset (no forewarning) of massive episodic memory impairment, both anterograde and retrograde. Ever since it was first described, TGA has fascinated neurologists and other memory experts, and in recent years, there has been a surge of neuroimaging studies seeking to pin down the brain dysfunction responsible for it. Several pathophysiological hypotheses have been put forward, including the short-lived suggestion of an epileptic mechanism...

Transient epileptic amnesia (TEA) is a recently individualized, late-onset, pharmaco-sensitive form of mesial temporal lobe epilepsy with recurrent episodes of acute memory loss, but also interictal memory disturbances characterized by autobiographical and topographical memory impairment and a long-term consolidation deficit. In this article, we review the main clinical and electrophysiological characteristics of TEA, discuss its putative neuroanatomical substrate and mechanisms, common features and how it differs from related concepts, with the overall aim to defend the idea that TEA deserves to be recognized as a distinct epilepsy syndrome...

We describe the case of a 79-year-old patient referred for suspected transient global amnesia, after an episode of anterograde amnesia which lasted 90 min. An EEG, performed after the episode, showed bilateral temporal electrographic seizures, orienting the diagnosis toward a transient epileptic amnesia. Transient epileptic amnesia is defined by temporal lobe epilepsy characterized by recurrent transient amnestic episodes of 30-90 min in duration, sometimes associated with olfactory hallucinations or oral automatisms...

Electroencephalogram (EEG) recording in the laboratory lasts at least 20 minutes and uses 19 active electrodes. It includes rest periods, stimulation procedures, a 3-mn hyperventilation period and intermittent photic stimulation (IPS). Recorded at the bedside, the EEG uses at least eight electrodes; the stimulation procedures, duration of the EEG and need to repeat the examination depend on the indication. Simultaneous video recording is recommended. The EEG report describes the basic rhythm, its reactivity and pathological activities, whether epileptic or not, and their organization...

Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of anterograde amnesia (the inability to encode new memories), accompanied by repetitive questioning, sometimes with a retrograde component, lasting up to 24 hours, without compromise of other neurologic functions. Herein, we review current knowledge on the epidemiology, pathophysiology, clinical diagnosis, and prognosis of TGA. For this review, we conducted a literature search of PubMed, with no date limitations, using the following search terms (or combinations of them): transient global amnesia, etiology, pathophysiology, venous hypertension, migraine, magnetic resonance imaging, computed tomography, electroencephalography, prognosis, and outcome...

Transient Global Amnesia (TGA) is a clinical syndrome characterized by temporary inability to form new memories described as anterograde amnesia. It is associated with retrograde amnesia and repetitive questioning. During the attack patients remain conscious and communicative and personal identity is preserved. Focal neurological symptoms and epileptic features are absent and general conditions appear intact. The ability to store new memories gradually recovers and subjects return to normal conditions except for a substantial amnestic gap for the duration of the attack...

Transient epileptic amnesia (TEA) is an epileptic syndrome characterized by recurrent, brief episodes of amnesia. Transient epileptic amnesia is often associated with the rapid decline in recall of new information over hours to days (accelerated long-term forgetting - 'ALF'). It remains unknown how recognition memory is affected in TEA over time. Here, we report a systematic study of picture recognition in patients with TEA over the course of one week. Sixteen patients with TEA and 16 matched controls were presented with 300 photos of everyday life scenes...
