Two Routes to Losing One’s Past Life: A Brain Trauma, an Emotional Trauma

open access: yesBehavioural Neurology, 2008
Organic and psychogenic retrograde amnesia have long been considered as distinct entities and as such, studied separately. However, patterns of neuropsychological impairments in organic and psychogenic amnesia can bear interesting resemblances despite ...

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, Volume 12, Issue 41, November 6, 2025.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Transient epileptic amnesia

open access: yesNeurologijos seminarai, 2018
Transient epileptic amnesia is an adult onset form of temporal epilepsy which is characterised by recurrent acute seizure-induced amnesia often accompanied by ongoing memory disturbances of autobiographical, topographical amnesia and accelerated long ...

Psychogenic amnesia: syndromes, outcome, and patterns of retrograde amnesia [PDF]

open access: yes, 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.

Modeling presynaptic inhibition by the amyloid precursor protein demonstrates one potential mechanism for preventing runaway synaptic modification in Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Previous simulations of Hebbian associative memory models inspired the malignant synaptic growth hypothesis of Alzheimer's disease (AD), which suggests that cognitive impairments arise due to runaway synaptic modification resulting from poor separation between encoding and retrieval.

Evaluation of the Sedative Activity of Naringenin: In Vivo Study with Pharmacokinetics and Molecular Docking Insights

open access: yesChemistryOpen, Volume 14, Issue 10, October 2025.
The study investigates the sedative potential of naringenin (NAR) through in vivo and in silico approaches. NAR significantly enhances sleep duration and reduces latency in mice, especially when combined with diazepam. Molecular docking shows strong binding to GABAA receptors, suggesting a GABAergic mechanism.

Long-term cognitive recovery following isolated bilateral infarction of the fornix presenting with amnesia

open access: yesBMJ Neurology Open
Introduction Isolated infarction of the fornix is a relatively rare stroke syndrome frequently associated with amnesia. The long-term cognitive outcome in cases of acute fornix infarction is poorly understood. This is largely due to the limited number of

Bilateral Hippocampal Infarction as Etiology of Sudden and Prolonged Memory Loss

open access: yesCase Reports in Neurology, 2012
Sudden memory loss, with prolonged cognitive deterioration, clinically initially resembling a transitory global amnesia (TGA)-like episode, might be caused by ischemic stroke in the hippocampal regions.

Median effective dosage of midazolam oral solution for preschool children in preoperative sedation

open access: yesIbrain, Volume 11, Issue 3, Page 385-392, Fall 2025.
This study aimed to detect median effective dosage (ED50) of midazolam oral solution (MOS) for preschool children in preoperative sedation. Thirty children who were scheduled for elective of the hidden penis correction surgery under general anesthesia in the pediatric surgery department were selected.

Transient global amnesia after the right temporal epilepsy surgery: A case report

open access: yesEpilepsia Open
Transient global amnesia (TGA) is characterized by sudden and temporary memory impairment, while transient epileptic amnesia (TEA) represents amnestic attacks as the main manifestation of focal epilepsy with presumed temporal origin. We present a 48‐year‐
