The word on the tip of the tongue
Memory, concentration, mental clarity: what actually happens during the transition
This information is intended to feed your reflection and enrich your dialogue with your naturopath. It does not constitute medical advice. Naturopathy supports, guides and nourishes the terrain: it in no way replaces medical diagnosis and prescription. Any therapeutic decision belongs exclusively to a doctor.
Why the brain changes
Without catastrophising. The cognitive changes of perimenopause are real, measurable and biologically explicable.
The word that vanishes
The word was there two seconds ago. You had it. And now it has gone, as if sucked away. You finish your sentence with "the thing, you know" and carry on, mildly irritated with yourself. About two-thirds of women report cognitive difficulties during the menopause transition, working memory, processing speed, verbal fluency, sustained concentration. These complaints are confirmed by objective neuropsychological tests.
Brain fog or warning sign
The question many women don't dare ask: is it the menopause, or is it early Alzheimer's?
Its features
• Fluctuating: good and bad days, tied to cycle and sleep. • Mostly targets working memory and verbal fluency. • Clear awareness of the problem, you know exactly what escapes you. • No major impact on daily life, work or relationships. You forget a word. You don't lose your keys in the fridge.
The documented levers
Three interventions with solid data on cognition in transition.
Sleep first
The glymphatic system clears cerebral metabolic waste (including beta-amyloid proteins) mostly during deep sleep (N3 stages). Memory consolidation also happens in N3. Fragmented or shortened sleep in perimenopause directly amplifies cognitive symptoms. Treating maintenance insomnia is often the lever that yields the fastest improvements in memory.

Nootropic plants
Three plants with clinical data on cognition. None replace the foundational levers.
Microcirculation and cholinergic
Mechanism: improved cerebral microcirculation + cholinergic modulation. Dosage: standardised EGb 761 extract, 120 to 240 mg/day, in 1 to 2 intakes. Minimum duration: 8 weeks to see an effect. Important contraindications: anticoagulants, aspirin, antiplatelets (additive effect on blood fluidity). Stop 2 weeks before any scheduled surgery.
What to ask your doctor
Four precise phrasings to structure the dialogue with your doctor.
Rule out treatable causes
"Before attributing my cognitive troubles to the menopause, can we rule out treatable causes, a complete thyroid work-up (TSH, free T3 and T4) and a vitamin B12 measurement with homocysteine?" This phrasing shows you know the main confounders and are requesting a targeted work-up, not a generic exam.
