The syndrome of transient epileptic amnesia.
OBJECTIVE Transient amnesia can be the principal manifestation of epilepsy. This diagnosis, however, is seldom suspected by clinicians and remains controversial. The amnestic attacks are often associated with persistent memory complaints. This study was designed to provide the first description of transient epileptic amnesia in a substantial series of patients. METHODS Fifty patients were rec...
متن کاملTransient global amnesia or transient epileptic amnesia?
Sir, We read with great interest the letter of McCorry and Crowley concerning an attack of transient global amnesia (TGA) considered secondary to herpes simplex viral encephalitis. Some features of the reported attack are unusual. The patient was a relatively young person: 39 years compared with an average age of 61 with TGA. At the beginning the patient suddenly became ‘distressed’; he realize...
متن کاملTransient global amnesia mimics: Transient epileptic amnesia
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...
متن کاملSemantic memory and frontal executive function during transient global amnesia.
To assess semantic memory and frontal executive function, two patients underwent neuropsychological testing during transient global amnesia (TGA) and after an interval of 6-8 weeks. In spite of a profound deficit in anterograde verbal and non-verbal memory, semantic memory was normal, as judged by category fluency measures, picture naming, and picture-word and picture-picture matching, and read...
متن کاملNew semantic learning and generalization in a patient with amnesia.
New learning of semantic information is impaired in amnesia. Several reports have demonstrated that "errorless" learning techniques have allowed patients with amnesia to acquire at least some form of new semantic information, although this information appears to be relatively inflexible. Using insights and principles from connectionist modeling of cortical and medial temporal lobe memory system...
