perimenopause brain fog
perimenopause brain fog
Menopause brain fog is primarily caused by falling estrogen, which disrupts brain energy metabolism, sleep, and mood regulation during perimenopause and menopause. Contributing factors include night sweats, insomnia, anxiety, depression, and midlife stress, while thyroid problems and vitamin deficiencies can mimic or worsen symptoms. For most women the fog is temporary and improves after the menopause transition, and it can be managed with HRT where appropriate, sleep and exercise habits, and practical memory strategies. This guide explains each cause, how long symptoms typically last, when brain fog is not dementia, and the treatments and vitamins with real evidence behind them.
