Key Takeaways Zostavax was linked to a 20% lower dementia risk in older adults over seven years. The effect was stronger in women, possibly due to immune differences. Findings …
Parenting Strengthens Aging Brains: Study Links Child-Rearing to Enhanced Neural Connectivity
Key Takeaways: Parents show stronger neural connectivity in aging-sensitive brain regions. Benefits apply equally to mothers and fathers. Effect scales with number of children. Parenting acts as “brain enrichment” …Gum Disease Bacteria Linked to Alzheimer’s: Porphyromonas gingivalis May Accelerate Cognitive Decline
Key Takeaways Porphyromonas gingivalis (Pg), a bacterium from gum disease, has been found in Alzheimer’s patients’ brains, possibly contributing to plaque buildup. Studies show that Alzheimer’s patients with periodontitis …
Early Exposure to Structural Sexism Accelerates Memory Decline in Women by Up to Nine Years
Key Takeaways: 9-Year Cognitive Gap: Women born in high-sexism states (e.g., Mississippi) experience memory decline equivalent to 9 additional years of aging compared to those in low-sexism states (e.g., …
