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 ...

Memory impairment caused by cerebral hematoma in the left medial temporal lobe due to ruptured posterior cerebral artery aneurysm [PDF]

, 2014
BACKGROUND: Cognitive disorders, such as memory disturbances, are often observed following a subarachnoid hemorrhage. We present a very rare case where rupture of a posterior cerebral artery aneurysm caused restricted damage to the hippocampus ...

Retrograde Amnesia For Forty Years

Cortex, 1982
We describe a patient who, in the absence of anterograde amnesia, experienced sudden onset of profound retrograde amnesia for the last forty years of his life. The amnesia encompassed all knowledge, including motor skills, acquired during these forty years. There has been no recovery in over eighteen months.

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.

Episodic-autobiographical memory and functional amnesia

Translational Neuroscience
Memory disorders belong to the most common concomitants of brain damage, but can be found as well in cases without directly measurable brain damage. These then belong in the category of psychiatric diseases.

Anterograde and Retrograde Amnesia following Bitemporal Infarction

Behavioural Neurology, 1994
A patient suffered very severe anterograde and retrograde amnesia following infarction of both medial temporal lobes (hippocampus and adjacent cortex) and the left inferior temporo-occipital area.

Transient global amnesia: an uncommon presentation of acute myocardial infarction

Italian Journal of Medicine, 2018
Transient global amnesia (TGA) is an acute neurological syndrome characterized by sudden-onset global (anterograde and retrograde) amnesia, without compromising other neurological functions. This clinical condition lasts up to 24 h with whole restoration.

Hypoxia and retrograde amnesia [PDF]

Psychonomic 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,

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

Air pollution and its multifaceted effects on insect pollinators: A review

Ecological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.
