6 evidence-based fixes
- 1. Protect deep sleep. Brain fog is a sleep-debt problem dressed up as a hormone problem. Aim for 7–9 hours and treat hot-flush wake-ups as a priority.
- 2. Cut alcohol to under 3 drinks per week. Single biggest lever for women who drink most nights.
- 3. Strength train 2–3x per week. Outperforms cardio for cognition in midlife women.
- 4. Eat protein at every meal. Stable glucose = stable focus. 30 g per meal is the target.
- 5. Omega-3, 2 g EPA+DHA daily. Modest but consistent benefit on processing speed.
- 6. Discuss HRT. Estrogen has direct neuroprotective effects on the hippocampus and prefrontal cortex.
Is it dementia?
Almost always no. Perimenopause fog is patchy, fluctuates with the cycle, and improves with sleep and rest. Dementia is progressive, doesn't fluctuate, and family or partners notice it more than you do. If a partner is genuinely concerned about decline, get a baseline cognitive assessment — it's reassuring almost every time.
