Mental health history and perimenopause
The menopause transition carries a documented, substantial increase in the risk of a first depressive episode — two to four times higher than at other points in life — and that risk is higher still for anyone with a prior history. This is worth naming specifically, rather than treating every mood change during perimenopause as an inevitable, untreatable part of the process.
What the research actually shows
Multiple studies find that women with no prior history of depression are two to four times more likely to experience a depressive episode during the menopause transition than premenopausal or postmenopausal women. For those who have had a depressive episode before, the risk during perimenopause is meaningfully elevated again on top of that baseline — evidence points to roughly a 50–60% greater chance of recurrence during this window compared with other times. Anxiety follows a similar pattern: a previous anxiety diagnosis is associated with greater risk of anxiety symptoms during perimenopause specifically, on top of whatever background risk already existed.
The proposed mechanism involves oestrogen's role in regulating mood-related neurotransmitter systems and the body's stress-response feedback loops — fluctuating rather than simply low hormone levels appear to matter here, which is part of why perimenopause (with its erratic swings) carries more mood-related risk than the more stable low-hormone state of established menopause.
Why this is worth logging specifically, not folding into "symptoms"
Ordinary perimenopause-related mood change — irritability after a bad night, low mood on a hard flash day — tends to track other symptoms and ease when they do. A depressive episode meeting clinical criteria is a distinct, treatable condition, and conflating the two risks either under-treating a real depressive episode as "just hormones," or over-medicalising ordinary mood fluctuation. A log that separates the two is more useful to a clinician than one that doesn't.
What to log
- Mood, tracked alongside your other symptoms — does it move with sleep and hot flashes, or does it feel constant regardless of what else is happening?
- Duration and persistence — clinical depression is typically present most of the day, most days, for two weeks or more, which is a different pattern from mood dipping on specific bad days.
- Any personal history of depression or anxiety, and roughly when.
- Anything that's changed in daily functioning — sleep, appetite, interest in things you usually enjoy — beyond mood itself.

About HormoneLog
HormoneLog is an iOS app from Baker Ventures LLC for tracking perimenopause and menopause symptoms and keeping an HRT record: what you took, at what dose, from when, and what changed afterwards. It is built for the appointment, where "it has been bad lately" is worth far less than a dated record of frequency and severity. The app is in development.
HormoneLog is a record-keeping tool. It does not diagnose, does not score you, and makes no claim about symptom relief. The guides on this site link to NICE, the NHS, the Menopause Society and peer-reviewed sources, and say plainly where the evidence is thin. Everything here is free and needs no account.
Questions and answers
Does perimenopause really increase the risk of depression?
Research consistently finds women who have never experienced depression are two to four times more likely to have a depressive episode during the menopause transition compared with before or after it — a substantial, well-documented increase in risk, not a minor association.
Does having depression or anxiety before perimenopause make it worse?
Evidence points that way — a prior history of depressive episodes is associated with a notably greater risk of another episode during perimenopause specifically, and a prior anxiety diagnosis carries a similar pattern.
Is this the same as normal mood symptoms of perimenopause?
Not necessarily. Perimenopause-related mood changes (irritability, low mood tied to sleep loss or hot flashes) are common and usually track other symptoms. A depressive episode meeting clinical criteria is a distinct, treatable condition worth naming specifically rather than folding into "just hormones."
Can HormoneLog diagnose depression or anxiety?
No. HormoneLog is not a mental health screening or diagnostic tool. It can help you log mood alongside other symptoms over time, which is useful context for a clinical conversation — the assessment itself is a clinician's job.
