Why does it happen?
Oestrogen has a direct neuroprotective role: it regulates acetylcholine synthesis (the memory neurotransmitter) and protects synapses. Its decline slows cognitive processing, causes frequent forgetfulness and makes concentration difficult. Sleep deprivation and elevated cortisol amplify these effects.
Characteristic symptoms
- Frequent forgetting of known words or names
- Difficulty concentrating on tasks that were previously automatic
- Feeling of "going in slow motion" mentally
- Greater reaction time and information processing
- Mental confusion or "blocking" in stressful moments
Omega-3s (EPA+DHA, 2 g/day) improve cognitive function and reduce brain fog in perimenopausal women. Phosphatidylserine (100 mg/day) and magnesium L-threonate show promising results in recent clinical studies.
Recommended habits
- High-purity omega-3 (EPA+DHA) as a neuroprotective base
- Restorative sleep — memory consolidates during deep sleep
- Aerobic exercise — increases BDNF (nerve growth factor)
- Meditation and mindfulness techniques — reduce cortisol that blocks memory
- Mediterranean diet — documented long-term cognitive protection
