Isolated Prolonged Retrograde Amnesia
European Neurology, 1992We describe a patient who had isolated retrograde amnesia of 1-year duration without anterograde amnesia after recovery from encephalitis. Single photon emission computed tomography using 123I-IMP revealed that left temporal lobe abnormality. We postulate that the learning ability for new information and recalling ability for old information involve ...

Retrograde amnesia and malingering
Current Opinion in Neurology, 2009Malingered anterograde amnesia is a phenomenon that has been exhaustively studied, whereas research on retrograde amnesia has tended to focus upon functional and organic accounts of impairment. The present review explores studies relevant to extending the malingering paradigm to retrograde amnesia.In the period reviewed, very little work has directly ...

Aphasiology, 1995
Abstract A case of severe retrograde and less severe anterograde amnesia with initial multimodal agnosia is described as an outcome of traumatic brain damage. Anatomical and metabolic studies document right frontal and left occipital lesions with sparing of medial temporal cortex.

Retrograde amnesia from electroconvulsive therapy
Neuropsychologia, 1978Abstract Retrograde amnesia for events occurring just before electroconvulsive therapy (ECT) has traditionally been interpreted as a failure of memory storage or consolidation. In a recognition memory experiment, the pattern of performance suggested that ECT may interfere with retrieval processes rather than disrupting consolidation.

The fractionation of retrograde amnesia
Brain and Cognition, 1988This single case study describes our investigations of the retrograde memory deficit of a patient who became severely and selectively amnesic after an encephalitic illness. On clinical assessment his retrograde deficit for both personal and public events appeared to encompass his entire adult life.

Functional (dissociative) retrograde amnesia
2016Retrograde amnesia is described as condition which can occur after direct brain damage, but which occurs more frequently as a result of a psychiatric illness. In order to understand the amnesic condition, content-based divisions of memory are defined. The measurement of retrograde memory is discussed and the dichotomy between "organic" and "psychogenic"

Retrograde amnesia following electroconvulsive therapy
Nature, 1976AMNESIC agents, such as electroconvulsive stimulation, can cause loss of memory for events that occurred before treatment1. Usually as the interval between learning and convulsive treatment is increased, the resulting retrograde amnesia is diminished1–3. This temporal gradient of retrograde amnesia can sometimes cover several years4.

Retrograde Amnesia in Petit Mal
Archives of General Psychiatry, 1962In our former research on the alterations of consciousness in petit mal (Jus and Jus, 1960) we were interested in different kinds of anterograde amnesia in petit mal and also devoted some attention to the problem of amnesia. In the present study we have made a more precise analysis of retrograde amnesia in petit mal.

Caudate stimulation and retrograde amnesia: Amnesia threshold and gradient
Behavioral Biology, 1972This experiment determined the threshold stimulation intensity needed for production of retrograde amnesia with 60 Hz caudate stimulation. With the stimulation parameters used, the necessary intensity is between 1 and 1.5 mA. This stimulation is an effective amnesic agent when administered 15 min, but not 60 min, after training.

Publisher Summary The retrograde amnesia (RA) phenomenon occurs in both animals and man and overwhelming evidence exists showing that a single electroconvulsive shock (ECS) treatment given after acquisition produces RA. Because ECS constitutes such a reliable RA treatment, drugs can be studied for their ability to duplicate the effects of this ...
