Depression in perimenopause: when your body changes, and your mood with it

“I don’t recognise myself any more. I used to manage everything, and now I burst into tears because the shop has run out of milk.”

This is a sentence I hear, in different forms, from women around forty and fifty. It is usually followed by an apology: “I know it’s nothing special.” And then a list: I sleep badly, I wake up at night drenched in sweat, at work I forget things I used to have at my fingertips, at home I am impatient with the people I love. Somewhere in between, almost in passing, comes one more line: “And somehow I don’t feel like doing anything any more.”

That last sentence is the one where I pause. Because tiredness, poor sleep and irritability are common in this period, and many women have them. But when they are joined by a greyness that does not lift, a loss of joy and a sense of having become a stranger to yourself, it is worth looking more closely. This piece is about exactly that: depression in perimenopause, why the risk is higher in these years, and what you can do — without me giving you advice that belongs in your gynaecologist’s consulting room.

What perimenopause actually is

Menopause is a single day: the moment twelve months have passed since your last period. Perimenopause is the years before that day and some time after it — the period when the ovaries gradually wind down, but not evenly. Hormone levels do not slide steadily downhill; they fluctuate: high one month, low the next, then different again. Cycles become unpredictable, shorter or longer, and sometimes one is skipped.

For most women perimenopause begins somewhere in their forties and can last several years. For some it passes almost unnoticed; for others it comes with hot flushes, night sweats, insomnia, joint pain, difficulty concentrating and changes in mood. And because all of this happens gradually, women often take a long time to connect it with perimenopause. They think they are overloaded, that they are getting old, or that something is wrong with them as people.

What the research shows

For a long time it was believed that “menopausal depression” was a myth — that women in these years were no more vulnerable than at any other time. Several large studies that followed women over many years changed that view.

In the Penn Ovarian Aging Study, Ellen Freeman and colleagues followed women with no previous history of depression over several years. During the menopausal transition they were roughly four times more likely to have markedly depressed mood than in the years before it. The Harvard Study of Moods and Cycles (Cohen and colleagues) found something similar: women who had entered perimenopause had about twice the risk of a first depression compared with women of the same age who had not yet reached it. The American SWAN study, which followed several thousand women of different backgrounds, found that the risk of a major depressive episode was higher during the transition and in the early years after it than before it.

It matters how you read these figures. They do not mean that most women in perimenopause will be depressed — they will not. They mean that in these years the window of vulnerability opens wider than usual. And that the feeling “I don’t recognise myself any more” can be more than a bad patch you simply have to grit your teeth through.

Why these years in particular

There is no single answer to the question of why perimenopause is a vulnerable time. But there are threads that keep recurring in the research.

Fluctuation, not just decline. It seems that mood is shaken less by low hormone levels as such than by their unpredictable swings. Oestrogen affects systems in the brain that regulate mood, sleep and the response to stress. When that influence becomes uneven, some brains react to it more strongly than others.

Not all women alike. Claudio Soares and other researchers speak of a continuum of vulnerability: some women are more sensitive to hormonal change, and this shows up at several points in life — before menstruation, after giving birth and in perimenopause. If you have ever experienced severe premenstrual distress, or if you read Postnatal depression: when you “should” be happy and you are not and recognised yourself in it, it is good to know that your body may be more sensitive to these transitions. That is not a weakness. It is information.

Sleep. Hot flushes at night, sweating, waking at three in the morning and being unable to get back to sleep. Some researchers call this the “domino effect”: bad nights lead to exhausted days, exhaustion to irritability and a sense of not coping, and that in turn to a mood that no longer lifts. I wrote about how closely sleep and mood are intertwined in Depression and sleep: why you sleep too much or too little; here I will only add that with long-lasting insomnia it is worth seeking help whether or not your mood has already been affected.

History. The strongest predictor of depression in perimenopause is whether you have had depression before. Women with a past history of depression are considerably more vulnerable in these years. If this applies to you, there is no reason to panic — but there is a reason to pay closer attention to early signs.

The years when everything happens at once

If perimenopause arrived in a calm stretch of life, it would probably be easier. But it often comes exactly when there is the most going on.

The children are in puberty or leaving home. Your parents are growing frail and need more and more help. At work you are at the peak of your responsibility, or you are asking yourself whether this is really all there is. After twenty years the relationship may be tired, and it is no longer clear what holds the two of you together when there are no children between you. Some women face separation, others illness, others the death of their parents. I wrote about the moment when the children leave in The empty nest: when the children leave and two strangers remain.

And then there is something quieter: your relationship with your own body and with ageing. In a culture that so often measures a woman’s worth by her youth, the end of fertility can be experienced as a loss, even if you no longer want children or never did. Some women feel relief. Others feel a sadness they cannot name. Often both.

In relational family therapy we see such periods as transitions in which it is not only the individual woman who changes, but the whole system around her. The roles you have held for twenty years — the one who cares, who copes, who holds everything together — may no longer work. And that can be deeply unsettling, especially if nobody around you notices that something has changed.

How depression in perimenopause can show itself

Depression in these years does not necessarily look the way we imagine it. It often does not look like crying in bed. Women describe it differently:

• Irritability and anger that seem out of proportion — followed by shame.
• Loss of joy in things that used to please you, including people.
• A feeling that you cannot cope, even though objectively you are doing as much as before.
• Anxiety that appears for no clear reason, sometimes with a racing heart.
• Brain fog — losing words, struggling to concentrate, fearing that something is happening to your brain.
• Self-criticism: “What is wrong with me? Other women manage.”

Some of these signs overlap with the symptoms of perimenopause itself, which makes telling them apart difficult. A general guide: if greyness, loss of joy and a sense of pointlessness last most days for two weeks or more and make life harder, that is a reason to talk to a professional. I have described in more detail how to distinguish depression from ordinary low mood in Depression is not sadness: how to tell them apart and why it matters. And you can read a short explanation of what depression is in the knowledge base.

If you ever have thoughts that it would be better if you were not here, do not carry them alone. In Slovenia, call the crisis line Klic v duševni stiski on 01 520 99 00 (every day from 7 pm to 7 am) or the Samaritans helpline (Zaupni telefon Samarijan) on 116 123 (24 hours a day). In an emergency, call 112.

A conversation worth starting in the consulting room

Because body and mind are so intertwined in perimenopause, it is good to talk about this with your gynaecologist or GP. Not because the answer necessarily lies in pills, but because it is important to rule out other causes (thyroid problems, for instance, can look similar) and because there are different options for help that need to be decided together with a doctor who knows your history.

I will not write here about which medication or hormonal treatment might suit you — that is not my field and it would not be fair. What I can do is help you arrive at that conversation prepared. Many women say they heard “it’s just your age” from their doctor and left without answers. Often because they themselves played down how they were feeling.

Professional guidelines for perimenopausal depression, drawn up by a group of American experts (Maki and colleagues), recommend that mood be checked systematically in women of these years and that depression not be attributed automatically to “hormones” or “age”. You have the right to be taken seriously.

Exercise: a map of your month

This exercise can help you see a pattern and, at the same time, prepare a concrete description for your doctor or therapist. You can start today.

1. Every evening, write down three numbers from 0 to 10: how you slept the night before, what your mood was like during the day and how much energy you had.
2. Add one line about your body: flushes, sweating, a period or bleeding, a headache — whatever you noticed.
3. Add one line about the day: what happened that weighed on you or brought you joy.
4. After four weeks, look at the whole. Do bad days follow bad nights? Do they appear in a particular part of the cycle? Are they linked to events?
5. Take your notes to your appointment. Instead of “somehow I’m not well”, you can say: “In the last month I slept less than five hours on 18 nights, and my mood was below four for 14 days.”

Writing things down has an effect of its own: it moves you from the role of the woman to whom “something is happening” into the role of the one who observes. It is a small but important shift. If structure helps you with sleep, the knowledge base also has a sleep diary.

The shame that makes everything harder

One of the hardest things I hear is not a symptom. It is shame. Shame because you “should be able to cope”. Shame in front of your partner, because you are impatient. Shame in front of your children, because you shout. Shame at work, because you forget the name of a colleague you have worked with for ten years.

Shame has a way of silencing women. And when they fall silent, they are left alone with the belief that something is wrong with them as people — not with the period they are going through. Women who have cared for others all their lives find it hard to admit that now they need care themselves.

The dialogue below is composite, not a real person — but I know it in many versions:

“I don’t even know why I came. It’s nothing serious.”
“What brought you here today?”
“Yesterday I shouted at my daughter because she hadn’t put her mug away. Then I cried in the bathroom for half an hour.”
“And while you were crying, what were you telling yourself?”
“That I’m a terrible mother. That I don’t recognise myself. That everything used to be easier.”
“As if you had lost someone you used to know.”
A long silence. “Yes. Myself.”

This “self I have lost” is often at the centre of therapy in these years. It is not about going back to the old version of yourself, but about finding a new one — one that does not have to manage everything in order to be worth something.

What can help — alongside your doctor

Depression in perimenopause is no different from depression at other times in the sense that it responds to the same forms of help. Psychotherapy is one of them. A few things are worth knowing:

Sleep is the first thing worth protecting. Cognitive behavioural therapy for insomnia has also proved effective in women in perimenopause. When sleep improves, mood often softens too.

Rumination has plenty to feed on in these years. Questions about meaning, about missed opportunities, about whether you have lived the right life. When these questions spin in a circle with no way out, they become rumination, which feeds depression. In therapy the same questions can become a source of reflection instead of a whirlpool.

Movement, daylight and contact with people remain reliable allies — not as a miracle cure, but as the foundation on which everything else stands.

Your partner and family can help a great deal if they understand what is going on. Often they do not. They think you are angry with them, or they withdraw because they do not know what to do. A conversation in which you tell them what is happening to you and what you need can be a relief for everyone. Sometimes it is easier to begin it with a therapist.

Where this story does not apply

I want to be honest here, because the “perimenopause” frame can also be a trap.

Not everything is hormones. If a woman in these years is experiencing violence, loss, loneliness or a load nobody could bear, her distress is not “hormonal”. It is a response to life. If we put everything down to hormones, we may overlook what actually needs to change.

Not everything is depression. Many women go through perimenopause with mood swings that are unpleasant but are not depression. Not every low mood needs to become a diagnosis. It is important to distinguish between a difficult period and an illness — and a professional can help you with that.

Not everything is just perimenopause. Depression can also appear at this time for other reasons and would have appeared regardless of hormones. That is why it matters that your doctor and therapist do not stop at the first explanation on offer.

It does not apply to everyone in the same way. The studies I have mentioned are mostly American and followed women in particular life circumstances. An individual woman’s experience can be very different. The figures say something about risk in a group, not about what will happen to you.

What to remember

• Perimenopause is a time when the risk of depression is higher — even in women who have never had it before.
• Mood is shaken by several threads at once: hormone swings, poor sleep and life turning points.
• Most vulnerable are women who have already had depression, severe premenstrual or postnatal distress.
• A conversation with your gynaecologist or GP matters — go prepared, with concrete notes.
• Shame is a poor adviser. Not recognising yourself is not a personal failing, but a signal that you need support.
