Synaptic degeneration in alzheimer disease
WebAlzheimer’s disease (AD) is a neurodegenerative disorder characterized by progressive dementia. AD suggests distinctive neuropathology and/or neurochemical deficiency in selective brain regions. It is considered the most common cause of dementia and accounts for 60%–70% of all cases of dementia. WebAstrocytes and microglia from human brains contain greater amounts of synaptic protein in AD compared to non-disease controls, and that proximity to amyloid-β plaques and the APOE4 risk gene exacerbate this effect. Synapse loss correlates with cognitive decline in Alzheimer’s disease (AD). Data from mouse models suggests microglia are important for …

Thus, identification and validation of biomarkers reflecting synaptic degeneration to be used as prognostic biomarkers are greatly needed. WebMar 3, 2024 · Neurofilament light (NfL) and neurogranin (Ng) are promising candidate AD biomarkers, reflecting axonal and synaptic damage, respectively. Since there is a need to understand the synaptic and axonal damage in preclinical Alzheimer’s disease (AD), we aimed to determine the cerebrospinal fluid (CSF) levels of NfL and Ng in cognitively …

Synaptic degeneration is a central pathophysiologic event of Alzheimer's disease (AD), 1 with a stronger association with the degree of cognitive decline in AD than amyloid plaque pathology. 2 This correlation makes a convincing argument for the development and implementation of synaptic in vivo biomarkers not … WebAbstract Alzheimer disease (AD) is biologically defined by the presence of β-amyloid-containing plaques and tau-containing neurofibrillary tangles. AD is a genetic and sporadic neurodegenerative disease that causes an amnestic cognitive impairment in its prototypical presentation and non-amnestic cognitive impairment in its less common variants.
