Implication of the thalamus in sleep alterations observed in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Alzheimer's disease (AD), the most common neurodegenerative disorder, is frequently accompanied by sleep disturbances. Alterations of sleep, in both quality and quantity, contribute to the progression of AD neuropathology. The thalamus, through its diverse nuclei, plays a central role in sleep regulation and sleep‐dependent memory ...

Progressive remote memory decline coincides with parvalbumin interneuron hyperexcitability and enhanced inhibition of cortical engram cells in a mouse model of Alzheimer’s disease

eLife
Patients with Alzheimer’s disease (AD) initially show temporally graded retrograde amnesia, which gradually progresses into more severe retrograde amnesia.

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

Case 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 ...

Psychophysiological correlates of peritraumatic dissociative responses in survivors of life-threatening cardiac events [PDF]

, 2002
The psychophysiological startle response pattern associated with peritraumatic dissociation (DISS) was studied in 103 survivors of a life-threatening cardiac event (mean age 61.0 years, SD 13.95).

Sex differences in neuromodulatory subcortical systems and their implications for Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...

Engram Synapses and Synapse Dynamics in Memory Processing

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Learning‐induced neuronal activity dynamically rewires synapses, altering their formation and elimination rates in task‐related regions. In vivo two‐photon imaging has revealed that activity‐driven presynaptic, postsynaptic, and astrocytic mechanisms regulate synaptogenesis and axonal bouton engulfment.

Persistent Leukoencephalopathy Following H1N1 Infection Associated With a Novel MYRF Variant (p.Gly735Asp)

Annals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 405-412, February 2026.
ABSTRACT Mutations in myelin regulatory factor (MYRF) are linked to demyelinating disorders. We report a 38‐year‐old male who developed acute symmetric leukoencephalopathy mimicking a stroke following an influenza A virus infection. While clinical symptoms markedly improved with corticosteroids, MRI revealed persistent white matter lesions, contrasting

Overtraining Strengthens the Visual Discrimination Memory Trace Outside the Hippocampus in Male Rats

Frontiers in Behavioral Neuroscience, 2021
The hippocampus (HPC) may compete with other memory systems when establishing a representation, a process termed overshadowing. However, this overshadowing may be mitigated by repeated learning episodes, making a memory resistant to post-training ...
