We carried out the first neuropsychological study of a series of patients with functional amnesia. We evaluated 10 patients, first with a neurological examination and then with three tests of anterograde amnesia and four tests of retrograde amnesia. Excluding one patient who later admitted to malingering, all patients had a significant premorbid psychiatric history and one or more possible prec...

Two patients with transient global amnesia are reported. Comprehensive neuropsychological evaluation, during the amnesic episode, as well as follow-up examinations on memory were performed. The course of the amnesia was exemplified by two comparable memory tests in different modalities. Partial retrograde amnesia and complete anterograde amnesia were demonstrated during the transient episode. O...

Patients with mild to moderate Alzheimer's disease and normal controls were tested on a retrograde amnesia test with semantic content (Neologism and Vocabulary Test, or NVT), consisting of neologisms to be defined. Patients showed a decrement as compared to normal controls, pointing to retrograde amnesia within semantic memory. No evidence for a gradient within this amnesia was found, although ...

BACKGROUND A history of loss of consciousness (LOC) is frequently used as an indication for cranial computed tomography (CT) in the emergency department (ED) evaluation of children with blunt head trauma. OBJECTIVE We sought to determine whether an isolated LOC and/or amnesia is predictive of traumatic brain injury (TBI) in children with blunt head trauma. METHODS We prospectively enrolled ...

I t has long been established that hypnotized subjects sometimes act in accordance with suggestions that they will not be able to remember specific information or events until given a retrieval cue (1-4). Subjects who exhibit this behavior, known as suggested hypnotic amnesia, when tested for recall, report none or only a portion of the specific information targeted by the amnesia suggestion. A...

OBJECTIVES To assess episodic memory (especially anterograde amnesia) during the acute phase of transient global amnesia to differentiate an encoding, a storage, or a retrieval deficit. METHODS In three patients, whose amnestic episode fulfilled all current criteria for transient global amnesia, a neuropsychological protocol was administered which included a word learning task derived from th...

Damage to the hippocampus and medial temporal (MT) structures can lead to anterograde amnesia and may also impair latent learning, in which prior exposure to cues affects their subsequent associability. Normally, latent learning may reflect both representational and attentional mechanisms. Prior work has suggested that individuals with MT amnesia have specific deficits in representational proce...

Amnesia following sedative-hypnotic drug exposure is discussed. Anterograde amnesia clearly occurs with many benzodiazepines. Several drugs are assessed: benzodiazepines and two hypnotics in particular that are structurally unrelated to the benzodiazepines but share some of their properties: zolpidem and zopiclone. The amnesic effects of these drugs are described, memory process, biology of mem...

Transient epileptic amnesia has been considered a syndrome of mesial temporal lobe epilepsy characterized by (1) recurrent episodes of isolated memory impairment of epileptic cause (ictal or postictal) while other cognitive functions remain intact; (2) interictal memory disturbances of accelerated long-term forgetting and autobiographical and topographical amnesia; and (3) late age of onset wit...

Amnesia suggestions were administered to 35 subjects of low, medium, and high hypnotic susceptibility who had learned a word list while hypnotized The method encouraged subjects to organize the words sequentially. Organization of recall was measured on recall trials conducted before, during, and after suggested amnesia. Highly hypnotizable subjects showed a breakdown in temporal organization du...
