Amnestically induced persistence in random walks

, 2007
We study how the Hurst exponent $\alpha$ depends on the fraction $f$ of the total time $t$ remembered by non-Markovian random walkers that recall only the distant past.

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 ...

Characteristics of psychiatric patients with nightmares after suvorexant administration: A retrospective study

Neuropsychopharmacology Reports, Volume 45, Issue 1, March 2025.
This study investigates the risk factors for nightmares among psychiatric patients treated with suvorexant, an orexin receptor antagonist. A retrospective analysis of 440 patients revealed that 9.1% experienced nightmares, with younger patients (aged 20–39 years) being at a significantly higher risk.

Post-concussion Vulnerability to Transient Global Amnesia

Frontiers in Neurology, 2020
Few studies have investigated transient global amnesia (TGA) in the context of a concussion and the concussion sequelae following TGA. Here we review the case of a 43-year-old male with onset of transient global anterograde and retrograde amnesia 22 days

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

BMJ 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

Memory consolidation from seconds to weeks: A three-stage neural network model with autonomous reinstatement dynamics

Frontiers in Computational Neuroscience, 2014
Declarative long-term memories are not created at an instant. Gradual stabilization and temporally shifting dependence of acquired declarative memories on different brain regions - called systems consolidation - can be tracked in time by lesion ...

Stabilization of mitochondria‐associated endoplasmic reticulum membranes regulates Aβ generation in a three‐dimensional neural model of Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 2, February 2025.
Abstract INTRODUCTION We previously demonstrated that regulating mitochondria‐associated endoplasmic reticulum (ER) membranes (MAMs) affects axonal Aβ generation in a well‐characterized three‐dimensional (3D) neural Alzheimer's disease (AD) model. MAMs vary in thickness and length, impacting their functions.
