Around two-thirds of
women 40+ are affected
by brain fog

This is related to the effects of changing hormone levels on the female brain. The first hormone level to drop is usually progesterone, and this can be related to irritability, mood swings and brain fog. The drop in progesterone can also cause sleep disturbance. Sleep disturbance in itself can affect the brain’s ability to function optimally.

Dips in oestrogen levels cause the well-recognised symptoms of menopause, including hot flushes, mood changes, irritability, mental confusion and decreased energy. These things can all further contribute to hormone-related brain fog.
