Women who hit menopause early see faster brain aging and earlier Alzheimer's diagnosis
Menopause is more than just the end of a woman's reproductive years. It brings a cascade of hormonal changes that can affect overall well-being, giving rise to a range of physical and emotional symptoms. A recent study published ...
A burst of 'pink noise' may lead to more restorative sleep
During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help wash away this waste, keeping the brain healthy.
