A closer look
If you've ever watched a perimenopausal woman walk into a room and instantly forget why she exists, don't laugh—her brain is literally starving for energy. Estrogen is the master regulator that pushes glucose into brain cells. When estrogen production violently crashes during perimenopause, neural metabolism drops by up to 30%. The brain has to panic and frantically rewire itself to use alternative fuel sources, resulting in a terrifying temporary cognitive dip that feels exactly like early-onset dementia.
