Better Diet May Prevent Brain Shrinkage in Older Adults

Older adults who eat a diet rich in vegetables, fruits, fish and nuts have greater brain volume, a new study reveals. Researchers say diet can influence brain shrinkage and the development of neurodegenerative diseases as we age.

Alzheimer’s Drug Shrinks Brain Volume by Removing Amyloid Plaques

Brain volume loss linked to new Alzheimer’s immunotherapies, such as lecanemab, is caused by the removal of amyloid plaques rather than neuronal damage. Researchers analyzed data from multiple trials and coined the term "amyloid-removal-related pseudo-atrophy" (ARPA) to describe this phenomenon.

Shrews Shrink and Regrow Brains, Offering Clues for Human Diseases

Scientists used non-invasive MRI to study shrews that seasonally shrink and regrow their brains, uncovering water loss as the key driver of this rare phenomenon. Despite losing about nine percent of their brain volume in winter, shrew brain cells remain alive, with aquaporin-4 proteins playing a key role in regulating water movement.

Sitting for Hours May Shrink the Brain

Prolonged sedentary behavior in adults over 50 is linked to cognitive decline and brain shrinkage in regions vulnerable to Alzheimer’s disease. Even among those who exercise regularly, spending more time sitting was associated with worse cognitive outcomes.

Middle Age Inflammation Linked to Brain Shrinkage Decades Later

According to a new study, people who have inflammation biomarkers in their blood during middle age are more likely to have increased brain shrinkage as they grow older. Researchers report the brain cell loss associated with inflammation was most prevalent in areas affected in Alzheimer's disease.

Smoking Linked to Brain Shrinkage, Irreversible Even After Quitting

Researchers found that smoking causes the brain to shrink and age prematurely, a condition not reversible even after quitting smoking. The study analyzed data from over 32,000 individuals in the UK Biobank, revealing a direct link between smoking, genetic predisposition, and reduced brain volume.
