A recent study conducted at the NYU Alzheimer Disease Research Center examined the risk factors and cognitive markers associated with progression in individuals with subjective cognitive decline (SCD). The study found that lower education, Hispanic ethnicity, and hypercholesterolemia were risk factors for progression in SCD, while APOE status was not. Additionally, SCD decliners were at increased risk for both amnestic and non-amnestic cognitive decline. These findings provide valuable information for future research on SCD outcomes and related biomarkers, as well as preventive studies targeting modifiable risk factors for SCD progression. Please note that this study has not yet undergone peer review. [Extracted from the article]

A recent study published in Protein & Cell explores the role of a noncoding RNA called Terc-53 in aging. The researchers created transgenic mice that overexpressed Terc-53 and found that this affected normal aging in mammals, leading to cognitive decline and a shortened lifespan. They discovered that Terc-53 binds to and promotes the degradation of a protein called Hmmr, which results in increased inflammation in tissues and accelerated aging. The study suggests that strategies aimed at stabilizing Hmmr could potentially mitigate age-related cognitive decline and inflammation, offering new avenues for understanding and treating age-related physical debilities.
