The anxiety that arrived from nowhere at 46, the rage you do not recognise, the word you cannot find. This has a name.
Perimenopause — the years of hormonal change leading up to the last period — commonly affects mood, anxiety, sleep and concentration, often years before periods stop. Many Nigerian women experience this as a sudden, frightening personality change with no explanation, because nobody told them it was coming. It is not a breakdown, and it is manageable.
The part nobody mentions
Most women know menopause involves periods stopping and hot flushes. Far fewer know that the transition into it typically lasts several years, can begin in the early forties, and that the mental symptoms often arrive first — while periods are still perfectly regular.
Which produces a specific and common experience: a woman in her mid-forties, functioning well her whole life, suddenly cannot sleep, is anxious for no reason, snaps at her children, cannot find ordinary words in meetings, and privately concludes she is losing her mind.
She is not. Oestrogen influences serotonin, sleep architecture and the brain’s stress response, and it does not decline smoothly during this period — it fluctuates, sharply. The mind responds to that.
What it actually feels like
Anxiety without a subject. Not worry about a specific thing. A physical anxiety that shows up on waking, often with a racing heart, attached to nothing.
Rage. The symptom women are most ashamed of. Irritation that goes from nought to fury over something trivial, followed by guilt. Frequently the first thing families notice.
Low mood. Sometimes genuine depression, and the risk of a depressive episode is elevated during this window — particularly for women with a history of PMS, postnatal depression, or previous depression.
Brain fog. Losing words mid-sentence, forgetting why you entered a room, reading the same paragraph three times. Deeply unsettling for professional women, and one of the most common reasons for quietly stepping back at work.
Sleep collapse. Waking at 3am and not returning to sleep, often with night sweats. Sleep loss then amplifies every other symptom — see our piece on insomnia, which explains why the pattern hardens once it starts.

Loss of confidence. Often the cumulative effect of all the above rather than a symptom in itself.
Our earlier piece, does menstruation affect women’s mental health?, covers the same hormonal machinery earlier in life. If your mood always tracked your cycle, you may find this transition harder — that is a known pattern, not bad luck.
Why Nigerian women are hit harder by it
Not biologically. Contextually.
Nobody discusses it. Menopause is not talked about between mothers and daughters, between friends, or in most Nigerian clinical encounters. Women arrive at it with no map at all.
It gets read as something else. Sudden rage, insomnia and personality change in a woman in her forties still attracts, in some families, an interpretation involving spiritual attack or the suggestion that she is becoming mentally unwell. Deliverance is proposed where a hormone conversation was needed.
It collides with the heaviest years. Mid-forties in Nigeria frequently means teenagers at home, ageing parents needing care, peak work responsibility and stretched finances. The symptoms arrive at the point of least available slack.
Marriages take the strain. Loss of interest in sex, painful sex, exhaustion and irritability — with no shared language for any of it — get read as rejection. Many couples spend years in that misreading without either naming the cause.
Care is uneven. Some Nigerian doctors are well-informed about menopause; many are not, and women are frequently told it is stress, or handed an antidepressant without anyone mentioning the hormonal transition at all.
Is it menopause or depression?
Often both, and the distinction matters because the treatment differs.
Pointers towards a hormonal driver: symptoms fluctuating rather than staying constant; arriving alongside cycle changes, hot flushes or night sweats; brain fog and sleep disturbance prominent; rage more prominent than sadness.

Pointers towards depression: persistent low mood most of the day, most days, for two weeks or more; loss of pleasure in everything; hopelessness; guilt and worthlessness; thoughts of not wanting to be here.
You do not have to resolve this yourself, and you should not have to. Say to a doctor: I am in perimenopause and my mood has changed. Naming it directs the conversation, which otherwise tends to skip the hormones entirely.

What helps
Treatment options exist, and they are a medical conversation. Hormonal and non-hormonal treatments both have a role, and suitability depends on your history — including any history of certain cancers or clotting disorders. This is a discussion with a doctor who knows your case, not something to decide from an article or an Instagram post. What is worth knowing is that treatment is available and effective for many women, and that suffering through it silently is not the only option.
Protect sleep first. It is the lever with the widest effect. If night sweats are waking you, that is a medical symptom worth treating rather than enduring.
Therapy helps, and it is not a consolation prize. CBT has good evidence for menopausal mood symptoms and even for the distress around hot flushes. It is also where the identity part gets addressed — ageing, fertility ending, being read as invisible — which no tablet touches. Filter for women’s mental health in our directory.
Tell your partner what is happening. Not an apology. Information. Most of the marital damage in this period comes from both people privately concluding something is wrong with the relationship.
Find the other women. Almost every woman a decade older has been through this and was never asked about it. Ask. The relief of discovering it is not just you is substantial.
Track it. Symptoms, cycle, sleep, mood. Useful for you and much more useful for a doctor than “I have not been myself”.
The reframe worth having
This is a transition, not a decline. It typically takes a few years, symptoms ease for most women once hormones settle, and many describe what follows as a distinctly steadier period of life.

What you should not do is spend those years believing you are failing at something. Your brain is adjusting to a real physiological change. That is worth treating properly — and worth saying out loud, in a country where almost nobody does.
Frequently asked questions
When does perimenopause start?
Commonly in the forties, sometimes earlier, and it typically lasts several years before periods stop. Mood symptoms often appear while cycles are still regular.
Can menopause cause anxiety and depression?
Hormonal fluctuation affects mood regulation, sleep and the stress response, and the risk of a depressive episode is raised during this window — especially with a history of PMS or postnatal depression.
Is brain fog in menopause permanent?
For most women it improves once hormones stabilise. It is genuinely disruptive at the time and worth taking seriously.
Should I take HRT?
That is a decision for a doctor who knows your medical history. Treatment is available and effective for many women; suitability varies, so ask rather than self-prescribe.
How do I know if it is menopause or depression?
Fluctuating symptoms with cycle changes, sweats, fog and rage point one way; persistent low mood, hopelessness and loss of pleasure point the other. Frequently it is both — a doctor can help separate them.
