Association Between Plasma Phosphorylated Tau‐217 and Cognition in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Alzheimer's disease (AD) co‐pathology contributes to dementia in PD, but its role in earlier cognitive impairment remains uncertain. Objective To determine if p‐tau217, a biomarker of early AD, is associated with cognitive impairment in PD.

Apolipoprotein E Uptake and Low-Density Lipoprotein Receptor-Related Protein Expression by the NTera2/D1 Cell Line: A Cell Culture Model of Relevance for Late-Onset Alzheimer's Disease

Neurobiology of Disease, 1997
Apolipoprotein E has been shown to be a risk factor for late-onset Alzheimer's disease, with the apolipoprotein ϵ4 allele conferring the risk. Apolipoprotein E is found in neurofibrillary tangles and senile plaques, the pathological characteristics of ...

Circadian rhythms and chronotherapy in Alzheimer's disease: Mechanisms and therapeutic implications

Neuroprotection, EarlyView.
Circadian dysregulation contributes to Alzheimer's disease through sleep disruption, clock‐gene dysfunction, neuroinflammation, impaired proteostasis, and metabolic imbalance. These alterations promote cognitive decline and disease progression, while circadian biomarkers and chronotherapeutic interventions offer opportunities for precision diagnosis ...

Alcohol consumption and cognitive function: A systematic review and dose–response meta‐analysis of 20 cohort studies

Addiction, EarlyView.
Abstract Background and aims Amid ongoing debate on whether low‐to‐moderate alcohol consumption reduces cardiovascular risk, studies examining the association between alcohol consumption and cognitive function have reported inconsistent results. To quantitatively assess this association, we conducted a dose–response meta‐analysis of cohort studies ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Neurofibrillary tangle-bearing neurons have reduced risk of cell death in mice with Alzheimer’s pathology

Cell Reports
Summary: A prevailing hypothesis is that neurofibrillary tangles play a causal role in driving cognitive decline in Alzheimer’s disease (AD) because tangles correlate anatomically with areas that undergo neuronal loss.

Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

Brain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

Emotional Lability as a Unique Presenting Sign of Suspected Chronic Traumatic Encephalopathy

Case Reports in Neurological Medicine, 2018
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease caused by head trauma. Diagnosis of this disease is difficult as reliable biomarkers have not been established and often this clinical entity is underappreciated with poor recognition ...
