Hippocampus, 2001
In humans, the phenomenon of temporally graded retrograde amnesia has been described in the clinic and the laboratory for more than 100 years. In the 1990s, retrograde amnesia began to be studied prospectively in experimental animals. We identified 13 published studies in which animals were given equivalent training at two or more separate times before

Neurocase, 2001
A patient with isolated autobiographical episodic memory is presented. The patient (male; 64 years old) was admitted to hospital suffering from double images and headache. CT examination revealed an arachnoid cyst at the anterior part of the left temporal lobe.

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.

Current Directions in Psychological Science, 2003
Recently, the field of animal memory research has seen a resurgence of interest in the mechanisms underlying retrograde amnesia (RA) and in the use of RA as a technique for studying memory processes. A recent report from a major neuroscience lab, which demonstrated RA for an old reactivated memory, revitalized the debate regarding the widely accepted ...

Journal of Mental Science, 1947
This study of retrograde amnesia of brief duration is based upon information furnished by 117 persons who had undergone, according to their statements, one or more terrifying incidents. All were men on full military duty, with the exception of three civilians, included as being of particular interest.

THE ÆTIOLOGY OF RETROGRADE AMNESIA
The Lancet, 1971Abstract To date, hypotheses of the aetiology of retrograde amnesia have focused on anatomical effects of traumatic lesions and on the presumed existence of short-term memory. The invariable association of retrograde amnesia with post-traumatic amnesia has been ignored as a clue to the origin of retrograde amnesia.

Isolated Prolonged Retrograde Amnesia
European Neurology, 2008We 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 the left temporal lobe abnormality. We postulate that the learning ability for new information and recalling ability for old information involve ...

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.

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 ...

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.
