While age is the greatest risk factor, Alzheimer’s is actually a specific brain disorder—distinct from normal aging. The true cause lies in brain degeneration, triggered by the formation of abnormal amyloid plaques and tangled nerve fibers (tau protein tangles) in the brain. Amyloid plaques accumulate between brain cells, disrupting neural communication and causing inflammation, which damages surrounding neurons. Meanwhile, tau tangles destroy the microtubule structure...

What Is Polycystic Ovary Syndrome? Polycystic ovary syndrome is a common endocrine disorder affecting women of reproductive age, impacting about 7-10% of women. ​ Why Does PCOS Often Lead to Obesity? Hormonal imbalance: Elevated male hormones (androgens) alter fat storage, causing fat to accumulate primarily in the abdomen.
