Alzheimer's disease affects women at nearly twice the rate it affects men, and the menopause transition is part of the reason why.
Declining estrogen touches the same regions of the brain responsible for memory and processing speed, which is why brain fog during perimenopause is a real, measurable symptom, not something to explain away as stress or age.
The protective factors are more within reach than that risk makes it sound. Sleep quality affects those same brain regions directly. Movement improves blood flow to them. Diet influences the inflammation that compounds brain fog when it's already present.
None of this reverses risk on its own, but it's the difference between managing decline and getting ahead of it. Save this for the day you need the reminder.
