If you've been feeling unusually anxious, low, or emotionally fragile in your 40s or early 50s, you're far from alone. Perimenopause — the transitional years leading up to menopause — can profoundly affect mental health, and it's a connection that remains widely under-recognised.
New clinical research published in early 2026 has brought this issue sharply into focus. A study conducted by Liverpool John Moores University and the Newson Clinic found that approximately 1 in 6 women experience suicidal thoughts during the perimenopause and menopause that are not being identified or treated effectively by their healthcare providers.
Why does perimenopause affect mental health?
The hormonal shifts that occur during perimenopause — particularly the decline in oestrogen and progesterone — have direct effects on brain chemistry. Oestrogen plays a key role in the production of serotonin and dopamine, the neurotransmitters most closely associated with mood, motivation, and emotional regulation.
When oestrogen levels fluctuate and eventually decline, many women experience:
- Increased anxiety or panic attacks (often for the first time)
- Low mood, tearfulness, or a sense of emotional numbness
- Brain fog, difficulty concentrating, and memory lapses
- Disrupted sleep, which compounds everything above
- Loss of confidence and a feeling that something is fundamentally "wrong"
The challenge is that these symptoms often appear before the more commonly recognised signs of menopause like hot flushes and irregular periods. This means many women — and their GPs — don't initially connect the dots.
What the latest evidence says about treatment
The 2026 research offers compelling data on the effectiveness of hormone replacement therapy (HRT) for menopause-related mental health symptoms. Among women who reported suicidal thoughts at the start of the study, these thoughts reduced by more than 90% after treatment with a combination of oestrogen, progesterone, and testosterone.
Importantly, the updated NHS prescribing guidance now states that HRT should be considered as a first-line treatment for new-onset low mood and anxiety during perimenopause, rather than defaulting to antidepressants. This is a significant shift in clinical practice.
If you are experiencing changes in your mood, sleep, or emotional wellbeing and you are in your 40s or 50s, it is worth considering whether perimenopause could be playing a role. You do not need to wait for your periods to stop before seeking help.
What can you do?
- Track your symptoms: Keeping a symptom diary can help you and your doctor identify hormonal patterns.
- Talk to a specialist: A gynaecologist with experience in menopause management can offer a thorough hormonal assessment.
- Don't accept "it's just stress": While stress can certainly contribute, hormonal changes deserve proper investigation.
- Consider HRT early: When started under 60, HRT is safe for most women and the benefits often extend well beyond hot flushes.
