Associating Cognition With Amyloid Status Using Partially Ordered Set Analysis

Frontiers in Neurology, 2019
Background: The presence of brain amyloid-beta positivity is associated with cognitive impairment and dementia, but whether there are specific aspects of cognition that are most linked to amyloid-beta is unclear.

Age-Dependent Neuroplasticity Mechanisms in Alzheimer Tg2576 Mice Following Modulation of Brain Amyloid-β Levels [PDF]

, 2013
The objective of this study was to investigate the effects of modulating brain amyloid-b (Ab) levels at different stages of amyloid pathology on synaptic function, inflammatory cell changes and hippocampal neurogenesis, i.e.

Inflammatory components in human Alzheimer's disease and after active amyloid-β42 immunization

, 2013
Inflammatory processes are important in the pathogenesis of Alzheimer's disease and in response to amyloid-β immunotherapy. We investigated the expression of multiple inflammatory markers in the brains of 28 non-immunized patients with Alzheimer's ...

Do beta-amyloid-targeted interventions improve cognition, physical functioning, and overt behaviour of Alzheimer's Disease (AD) patients: Protocol for meta-analysis of Phase 3 clinical trials both completed and terminated.

PLoS ONE
Accumulation of amyloid-beta (Aβ) in the brain has been explored as a primary cause of Alzheimer's Disease (AD). Better known as the amyloid hypothesis, it has been the main target of researchers vying to bring their therapeutic interventions to market ...

Regulation of Mint1-dependent APP trafficking by N1-Src [PDF]

, 2012
Alzheimer’s disease (AD) is a neurodegenerative disease characterised by the accumulation of Amyloid-beta (Aβ) plaques and neurofibrillary tangles. Aβ plaques form as a result of improper trafficking and processing of the Amyloid precursor protein (APP).

Changes in intracellular calcium and glutathione in astrocytes as the primary mechanism of amyloid neurotoxicity [PDF]

, 2003
Although the accumulation of the neurotoxic peptide {beta} amyloid ({beta}A) in the CNS is a hallmark of Alzheimer's disease, the mechanism of {beta}A neurotoxicity remains controversial.

Unraveling Alzheimer’s: the promise of aducanumab, lecanemab, and donanemab

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery
Alzheimer’s disease (AD) is a neurodegenerative condition that causes cognitive decline, memory loss, and reduced personal autonomy. The pathology of AD involves the aggregation of abnormal brain proteins, specifically beta-amyloid plaques and tau ...

The Effect of Amyloid Beta on Synapses

, 2019
Alzheimer's disease (AD) is a neurodegenerative disease that leads to cognitive deficits. The brain dysfunction in AD is marked by an increase in amyloid-beta, the protein responsible for plaque deposition in the brain.
