Beyond amyloid plaque, targeting alpha-synuclein in Alzheimer disease: The battle continues

9 months ago
Alzheimer's disease (AD) is the most common neurodegenerative brain disease and represents the most frequent type of dementia characterized by cognitive impairment and amnesia. AD neuropathology is connected to the development of synaptic dysfunction and loss of synaptic homeostasis due to an imbalance in the production and clearance of β-amyloid (Aβ) and intracellular neurofibrillary tangles (NFTs). However, AD neuropathology is complex and may relate to the deposition of other misfolded...

Reclassification of the conventional risk assessment for aging-related diseases by electrocardiogram-enabled biological age

9 months ago
An artificial intelligence (AI)-enabled electrocardiogram (ECG) model has been developed in a healthy adult population to predict ECG biological age (ECG-BA). This ECG-BA exhibited a robust correlation with chronological age (CA) in healthy adults and additionally significantly enhanced the prediction of aging-related diseases' onset in adults with subclinical diseases. The model showed particularly strong predictive power for cardiovascular and non-cardiovascular diseases such as stroke,...

Differences in cholinergic terminal density in adults with Down syndrome compared to neurotypical controls measured by [<sup>18</sup>F]-fluoroethoxybenzovesamicol positron emission tomography imaging

9 months ago
Adults with Down syndrome are genetically predisposed to developing Alzheimer's disease after the age of 40. The cholinergic system, which is critical for cognitive functioning, is known to decline in Alzheimer's disease and although first investigated in individuals with Down syndrome 40 years ago, remains relatively understudied. Existing studies suggest individuals with Down syndrome have an intact cholinergic system at birth that declines through adulthood alongside the development of...
