Retrograde Amnesia – A Question of Disturbed Calcium Levels? [PDF]
Frontiers in Cellular Neuroscience, 2021 Retrograde amnesia is the inability to remember events or information. The successful acquisition and memory of information is required before retrograde amnesia may occur. Often, the trigger for retrograde amnesia is a traumatic event.

Increased Pupil Size during Future Thinking in a Subject with Retrograde Amnesia [PDF]
Brain Sciences, 2022 Recent research has assessed pupil size during past thinking in patients with retrograde amnesia. Building on this research, we assessed pupil size during future thinking in a retrograde amnesia patient.

Shrinking retrograde amnesia. [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1967 Frank Benson and I decided to publish this case not because the phenomenon was new — Ritchie Russell and Peter Nathan had described it in 1946 — but because it had been neglected. Thus many animal experimenters had attempted to study the time course of consolidation of memory traces by such experiments as teaching the animal a task and after a variable

Silent memory engrams as the basis for retrograde amnesia. [PDF]
Proc Natl Acad Sci U S A, 2017 Recent studies identified neuronal ensembles and circuits that hold specific memory information (memory engrams). Memory engrams are retained under protein synthesis inhibition-induced retrograde amnesia.

Profound loss of general knowledge in retrograde amnesia: Evidence from an amnesic artist [PDF]
Frontiers in Human Neuroscience, 2014 Studies of retrograde amnesia have focused on autobiographical memory, with fewer studies examining how non-autobiographical memory is affected. Those that have done so have focused primarily on memory for famous people and public events—relatively ...

An “Engram-Centric” Approach to Transient Global Amnesia (TGA) and Other Acute-Onset Amnesias [PDF]
Neurology InternationalThe differential diagnosis of acute-onset amnesia includes transient global amnesia (TGA), transient epileptic amnesia (TEA), and functional (or psychogenic) amnesia.

Psychogenic amnesia: syndromes, outcome, and patterns of retrograde amnesia [PDF]
Brain, 2017 There are very few case series of patients with acute psychogenic memory loss (also known as dissociative/functional amnesia), and still fewer studies of outcome, or comparisons with neurological memory-disordered patients. Consequently, the literature on psychogenic amnesia is somewhat fragmented and offers little prognostic value for individual ...

Memory. Engram cells retain memory under retrograde amnesia. [PDF]
Science, 2015 Memory consolidation is the process by which a newly formed and unstable memory transforms into a stable long-term memory. It is unknown whether the process of memory consolidation occurs exclusively through the stabilization of memory engrams.

Retrograde amnesia following electroconvulsive therapy for depression: propensity score analysis
BJPsych OpenRetrograde amnesia for autobiographical memories is a commonly self-reported cognitive side-effect of electroconvulsive therapy (ECT), but it is unclear to what extent objective performance differs between ECT-exposed and ECT-unexposed patients with ...

Focal retrograde amnesia: voxel-based morphometry findings in a case without MRI lesions. [PDF]
PLoS ONE, 2011 Focal retrograde amnesia (FRA) is a rare neurocognitive disorder presenting with an isolated loss of retrograde memory. In the absence of detectable brain lesions, a differentiation of FRA from psychogenic causes is difficult. Here we report a case study
