Retrograde amnesia in patients with Alzheimer's disease [PDF]

open access: yes, 2006
Patients with mild to moderate Alzheimer's disease and normal controls were tested on two retrograde memory tests, one based on public events, and the other querying autobiographical memory. On both tests, patients showed strong decrements as compared to

Neuropeptide cyclo-L-prolylglycine counteracts scopolamine-induced long-term memory impairment in rats in the novel object recognition test

open access: yesФармакокинетика и Фармакодинамика, 2023
Background. Cyclo-L-prolylglycine (CPG) was designed and synthesized at the V.V. Zakusov as a topological analogue of the classical nootrop piracetam and was further identified as an endogenous compound. Previously, the nootropic effect of CPG was revealed

Concept Cells and the Neural Bases of Human Memory

open access: yesActa Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Single‐neuron recordings from the medial temporal lobe of patients undergoing epilepsy surgery have revealed “concept cells” that respond selectively and invariantly to meaningful stimuli such as specific people, places, or objects. These responses offer a unique window into how individual neurons encode high‐level, multimodal representations ...

Hypoxia and retrograde amnesia [PDF]

open access: yesPsychonomic Science, 1970
Recent studies have questioned the phenomenon of hypoxia-produced RA on the premise that intracellular hypoxia cannot be produced rapidly enough to prevent the memory-consolidation process., Sixteen albino rats were trained to lever press for sucrose and were subjected to one of four treatments: shock only, hypoxia only, shock plus rapid decompression,

Amnesia of Uncertain Etiology in an Adolescent during COVID-19 Pandemic: A Case Report

open access: yesCase Reports in Neurology, 2022
Sudden retrograde memory loss, in the absence of neurological causes, is usually referred to as a dissociative symptom. Dissociative amnesia, defined in the DSM-V as an inability to remember important autobiographical experiences, usually of a traumatic ...

Co‐pathologies and biological processes beyond amyloid‐beta and tau in people with Alzheimer's disease: Evidence from clinical cohort studies

open access: yesJournal of Internal Medicine, Volume 299, Issue 6, Page 694-710, June 2026.
Abstract Alzheimer's disease (AD) is neuropathologically defined by amyloid‐beta (Aβ) plaques and tau neurofibrillary tangles. However, co‐pathologies and other pathobiological processes are involved in the pathogenesis of AD, contributing to neurodegeneration and clinical symptoms.
