Posted Today Humans aren’t the only ones who grow forgetful as they age — fruit flies do, too. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that comes with aging. Brain – illustrative photo.

Trauma exposure accelerates brain aging which can lead to Alzheimer’s disease, study suggests
September 10, 2024 by The North American Menopause Society Credit: Human Brain ProjectAs the median age of our population rises, so does the number of people diagnosed with Alzheimer’s disease. With advances in technology, it’s easier to determine brain age and identify blood-based Alzheimer’s disease biomarkers. A new study links trauma exposure with brain age...

Brain Aging Trajectories Identified in Post-Mortem Tissue
— Alzheimer’s may be driven by multicellular communities, analysis suggests by Judy George, Deputy Managing Editor, MedPage TodaySeptember 3, 2024 Key TakeawaysTwo distinct pathways of brain aging emerged in a cellular analysis of post-mortem brain tissue.One trajectory led to Alzheimer’s disease, the other to an alternative brain aging pathway.Cellular communities, not singular cell subpopulations, may...

Gender variations in brain aging among Parkinson’s Disease patients
By Vijay Kumar MalesuReviewed by Lily Ramsey, LLM In a recent study published in npj Parkinson’s Disease, researchers explored how sex influences brain aging in Parkinson’s disease (PD) by analyzing Magnetic Resonance Imaging (MRI)-derived brain age differences and their clinical correlations. Study: Differences in brain aging between sexes in Parkinson’s disease. Image Credit: SpeedKingz/Shutterstock.comStudy: Differences...

Long-term type 1 diabetes associated with accelerated brain aging
by Justin Jackson, Medical Xpress Machine Learning Indices, SPARE-AD and SPARE-BA, as a Function of Age. A, there was no significant difference observed between EDIC participants (blue) and controls without diabetes (orange). In panel B, EDIC participants showed a significant increase in predicted brain age (SPARE-BA) demonstrating more advanced brain aging patterns. SPARE-AD indicates spatial...

Study examines brain aging in people with schizophrenia
by CORDIS Correlation coefficients of predicted brain age and FreeSurfer features across control and schizophrenia (SZ) groups. Bivariate correlations are shown to provide an indication of the relative contribution of features in brain age prediction. The figure shows Pearson correlations between predicted brain age and cortical thickness features (top row), cortical surface areas (middle row)...

COVID-19 infection in crucial brain regions may lead to accelerated brain aging
by Houston Methodist The interaction of SARS-CoV-2 with olfactory cilia for entering the central nervous system (CNS). A) Different layers of cells in the nasal cavity that contain receptors for the very first viral entry into the human host. Some of the olfactory cells express ACE2 receptors that endocytose bound viral particles, before their way...

Genetic ‘hotspots’ that speed up and slow down brain aging could provide new targets for Alzheimer’s drugs
by University of Southern California Credit: CC0 Public Domain Researchers from a USC-led consortium have discovered 15 “hotspots” in the genome that either speed up brain aging or slow it down—a finding that could provide new drug targets to resist Alzheimer’s disease and other degenerative brain disorders, as well as developmental delays. The research appears...

Multivitamins, but Not Cocoa, Tied to Slowed Brain Aging
Pauline Anderson Taking a daily multivitamin for 3 years is associated with a 60% slowing of cognitive aging, with the effects especially pronounced in patients with cardiovascular (CVD) disease, new research suggests. In addition to testing the effect of a daily multivitamin on cognition the COSMOS-Mind study also examined the effect of cocoa flavanols, but showed no...
