Researchers developed a nasal spray that reversed brain aging and improved memory in test models by reducing inflammation and restoring cellular energy.

A UCSF study indicates that current vitamin B12 guidelines may not protect the aging brain, as lower active B12 levels are linked to cognitive issues and brain damage in older adults.

Researchers discovered that boosting a protein called Sox9 helps the brain's astrocytes clear Alzheimer's plaques and preserve cognitive function in mice.

A Rutgers University study found that internalized stress, especially hopelessness, may speed up memory decline in older Chinese Americans, highlighting the need for culturally sensitive stress relief.

A routine blood test marker, the neutrophil to lymphocyte ratio, may predict a person's risk of developing Alzheimer's disease years before symptoms appear, suggesting immune cells could play a role in the disease's progression.
