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.

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 ...

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.

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
