Maternal Genetics May Boost Alzheimer’s Disease Risk
It’s a well-known fact that Alzheimer's disease is influenced by genetic factors. Certain gene variants, such as the APOE gene, are known to increase susceptibility to the disease. Now, a new study from Mass General Brigham suggests that susceptibility to Alzheimer’s may run most strongly on the maternal side of the family.
In a comprehensive study involving over 4,400 cognitively unimpaired older adults ages 65 to 85, researchers examined the influence of maternal versus paternal history of memory impairment on brain health indicators linked to Alzheimer's disease.
Their findings revealed that those with a maternal history of late-onset Alzheimer's disease showed higher levels of β-amyloid (Aβ) in the brain, which is correlated with Alzheimer’s, as well as reduced brain metabolism and lower gray matter volumes compared to those without this family history. Paternal history did not demonstrate the same association with these biomarkers.
Interestingly, a paternal history of early-onset memory impairment (before age 65) was correlated with increased Aβ-PET levels, which correlate with a buildup of β-amyloid (Aβ), while late-onset paternal history did not show a significant association. These sex-specific correlations may allow doctors to identify those at high risk for Alzheimer’s disease more effectively.
Green Tea Promotes Healthy Skin Aging + Reduces Wrinkles
Green tea has a truly impressive antioxidant content that soars past many superfoods, including most fruits and vegetables. Its primary antioxidants are flavonoids, a subgroup of polyphenols, and catechins, particularly abundant in green tea leaves—flavonoids alone can make up to 30% of their dry weight.
These antioxidants contribute significantly to green tea’s skin-enhancing powers, including helping to combat signs of aging as well as promoting a clear complexion. In studies, green tea helped to improve skin elasticity when consumed or applied topically. The main antioxidant in green tea, EGCG, has even shown an ability to “re-energize” dying skin cells, causing them to start dividing again.
Other research has shown that green tea extracts may have benefits for delaying collagen aging. Collagen is one of the main skin proteins that helps to keep your skin plump and wrinkle-free, so this is a major finding.
Along with these powerful anti-aging properties, green tea can also calm inflammation and has antimicrobial effects, giving it the potential to help skin issues like acne, dermatitis, rosacea, and psoriasis. Plus, here are more of the many ways green tea can improve your health.
