Mental health is one of the most important — and most overlooked — aspects of the menopause transition.

The research is clear:

A landmark study by Freeman et al. (2006) published in *Archives of General Psychiatry* found that women in perimenopause are 2-4 times more likely to experience clinically significant depressive symptoms compared to premenopausal women. This includes first-onset depression in women with no prior psychiatric history. The SWAN Study has similarly confirmed elevated depression risk during the menopausal transition, with 45-68% of perimenopausal women reporting some depressive symptoms. SWAN also found that higher variability in estradiol and FSH across the transition is associated with increased depressive symptoms (Epperson et al., J Clin Endocrinol Metab, 2020).

Why does this happen?

Estrogen and progesterone influence the production, release, and reuptake of key neurotransmitters:

  • Serotonin — mood, appetite, sleep (estrogen increases serotonin production and receptor sensitivity)
  • Dopamine — motivation, pleasure (estrogen modulates dopamine pathways)
  • GABA — calm, relaxation (progesterone's metabolite allopregnanolone enhances GABA activity; as progesterone drops, this calming effect diminishes)
  • Norepinephrine — stress response

The fluctuations — not just the low levels — are what destabilize these systems. This is why mood symptoms can be unpredictable during perimenopause.

Anxiety:

New-onset anxiety is extremely common during perimenopause. Women often report feeling 'on edge,' having racing thoughts, or experiencing panic symptoms for the first time. Recognizing this as a perimenopause symptom is crucial for getting the right treatment.

What to do:

  • Talk to your doctor about both hormone therapy and mental health options
  • Cognitive Behavioral Therapy (CBT) has strong evidence for both hot flash bother and mood symptoms — Level I evidence, recommended by The Menopause Society (2026) and NICE (updated 2026)
  • Regular aerobic exercise (30 min, 5x/week) is as effective as mild antidepressants for mild-moderate depression
  • SSRIs/SNRIs in low doses can help — paroxetine, escitalopram, venlafaxine also reduce hot flashes
  • Hormone therapy alone may resolve mood symptoms without antidepressants in some cases
