Dementia

New research suggests lifelong musical practice protects the brain's ability to process speech in noisy rooms, delaying the effects of aging.

A new analysis reveals that Alzheimer’s disrupts mitochondrial function and insulin signaling more severely in women than men. The study suggests female brains may attempt unique biological compensations to fight the disease’s progression.

Researchers analyzing long-term data found that adherence to nutritious plant-based diets is positively associated with the brain's resilience against aging, while diets high in processed plant foods show an inverse relationship.

Recent research suggests that the number of words a person can list in just fifteen seconds may effectively predict their broader cognitive health, outperforming the traditional one-minute evaluation.

A ten-year study of older adults indicates that adverse childhood experiences leave a lasting mark on cognitive abilities. This negative link persists even when accounting for distinct patterns of physical and mental aging.

Probiotic supplements may offer a brain boost for aging adults. A new meta-analysis reveals that daily consumption improves memory and cognitive function in seniors, highlighting a link between gut health and mental acuity.

Researchers have preserved memory in mice by triggering support cells to remove amyloid deposits. The findings suggest that enhancing the brain’s natural cleaning system could offer a new therapeutic path for neurodegenerative conditions.

The Alzheimer’s therapy Lecanemab appears to recruit the brain’s immune system. New findings in Nature Neuroscience suggests the drug uses its Fc region to trigger microglia into removing amyloid plaques.

Researchers have found that consuming arginine reduces amyloid beta accumulation in mice and fruit flies. This common amino acid improved behavioral symptoms, pointing to a potential new strategy for managing Alzheimer's pathology.

A new study in rats shows that while high-fat and high-sugar diets both impair memory, only sugar triggers the accumulation of Alzheimer’s-associated proteins within the energy centers of brain cells.

A new study suggests repurposing existing cancer drugs could offer a potent treatment for Alzheimer’s. The combination therapy, tested in mice, works by correcting gene expression errors across both neurons and support cells.

A new study published in Nature suggests that following the Mediterranean or MIND diets is associated with better cognitive health and slower brain shrinkage in older adults over a five-year period.

The scars of childhood abuse may extend to the aging brain. New research following participants for over 30 years shows that documented maltreatment predicts lower intelligence scores and faster cognitive decline by age 59.

The popular metabolic drug semaglutide failed to preserve memory in patients with early Alzheimer’s disease. New data shows the treatment did not slow cognitive decline compared to a placebo, despite influencing disease-related biology.

A study of over 20,000 adults suggests that diets high in inflammatory foods are linked to accelerated brain aging. This association appears strongest in individuals over the age of 60.
