Menopause and mental health: mood, sleep and brain fog

Menopause is the point when periods stop for good. Doctors call it menopause after 12 months in a row with no period. The years before that, when periods become irregular, are called perimenopause (the menopause transition). For many women this stretch lasts several years.

Hot flashes get most of the attention. But many women also notice changes in mood, sleep and thinking. These changes are real, common and treatable. This page explains why they happen, what the research shows, and how to get the right help.

Signs to watch for

Changes often come and go, and they can overlap. Common ones include:^1,2

• Feeling low, tearful or flat, or losing interest in things you enjoy
• Feeling anxious, on edge or irritable, sometimes for no clear reason
• Hot flashes and night sweats that wake you up
• Waking in the night and not getting back to sleep
• Trouble finding words, focusing or remembering where you put things
• Feeling tired during the day, which makes everything harder

You can use the menopause symptoms check to keep track. Bring the results to your appointment. If you are over 45 and have hot flashes and irregular periods, a clinician can usually diagnose perimenopause from your symptoms alone. A blood test is often not needed.³

Why it happens

Hormone swings. Estrogen acts on many parts of the brain, including areas that control mood. In perimenopause, estrogen levels rise and fall in large, uneven swings. Experts think some women are more sensitive to these swings. The exact cause is not fully known.¹

Hot flashes and poor sleep. Night sweats break up sleep, and poor sleep makes mood worse. Hot flashes can also feed anxiety, because they are sudden and can feel embarrassing. Anxious thoughts, in turn, can set off hot flashes.¹

Life at midlife. Many women in their 40s and 50s are also caring for parents or children, working hard, or facing loss or health problems. Research on depression during perimenopause lists these risk factors:²

• Depression earlier in life
• Mood symptoms before periods (PMS) or after giving birth
• Bothersome hot flashes and poor sleep
• Stressful life events, money worries and little support from others

How it affects mind and body

Depression. Most women do not develop depression at menopause. But the risk rises during the transition, especially for those with a history of depression.¹ Depression is more than feeling down. It can affect sleep, appetite, energy and hope. Learn about the different types of depression.

Anxiety. Anxiety disorders are more common in women than in men from the teen years through menopause.¹ Panic-like feelings during a hot flash are common. See anxiety if worry is taking over.

Sleep. Trouble staying asleep is especially common from age 50 to 64. In 2024, about 22% of US adults in that age group had this problem most days or every day.⁴ Read more in our guide to sleep and insomnia in midlife.

Memory and brain fog. Trouble concentrating and remembering is common in the transition and the years after. Poor sleep and low mood play a big part. Dementia is rarely the cause, and Alzheimer's disease is rarely diagnosed before age 60. Still, big or worsening changes should be checked, because many causes can be treated.¹ Hormone therapy is not recommended just to improve memory after natural menopause.¹

What helps

Different treatments help different problems. Many women use more than one.

What changed for hormone therapy

For many years, hormone therapy labels carried a "boxed warning," the FDA's strongest kind of warning. In November 2025, the FDA began removing the boxed-warning statements about heart disease, breast cancer and probable dementia. It asked 29 drug companies to update their labels.^5,6

On February 12, 2026, the FDA approved the first 6 updated labels. They cover pills or patches with estrogen and a progestogen, estrogen alone, progestogen alone, and vaginal estrogen.⁶ Other products are being updated one at a time.

What did not change:

• The boxed warning about endometrial cancer (cancer of the lining of the uterus) stays on systemic (whole-body) estrogen-alone products, such as pills or patches.⁵
• The label advises starting hormone therapy before age 60, or within 10 years of menopause. Timing and length of use are still decisions for you and your prescriber.⁵
• The Menopause Society says risks are low for younger, healthy women who start near menopause, and higher for those who start later. It still advises a careful, personal review of your health history.⁷

New non-hormonal medicines

Elinzanetant (Lynkuet) was approved by the FDA on October 24, 2025, for moderate to severe hot flashes due to menopause.⁹ Its label warns about:¹⁰

• Sleepiness and slowed reactions. Do not drive or do risky tasks until you know how it affects you.
• Liver effects. Liver blood tests are needed before starting and again about 3 months later.
• Seizures in people with a seizure history, and harm in pregnancy.

The most common side effects were headache, tiredness, dizziness and sleepiness.¹⁰

Fezolinetant (Veozah) works in a similar way. In December 2024, the FDA added a boxed warning about rare but serious liver injury. People taking it need liver blood tests before starting and several times during the first months.¹¹ Stop it and call your prescriber right away if you notice:¹¹

• Unusual tiredness, nausea or vomiting, or itching
• Dark urine or light-colored stools
• Yellow skin or eyes, or pain in the upper right belly

Talk with your doctor or pharmacist before starting, stopping or changing any medicine.

Steps you can take this month

1. Track for 2 to 4 weeks. Note hot flashes, sleep, mood, periods and memory slips. The menopause symptoms check and sleep diary make this easy.
2. Check your mood. Take the depression test. Bring your score to your visit.
3. Book a visit and name your goals. For example: "I want to sleep through the night" or "I feel low most days." Ask which treatments fit your health history.
4. Protect sleep. Keep a steady wake-up time, keep the bedroom cool, and limit alcohol, which can worsen night waking. See healthy sleep habits.
5. Move most days. A daily walk helps mood and sleep. Try the walking plan.
6. Calm the body during a hot flash. Paced breathing has not been shown to reduce hot flashes.⁸ But slow breathing like the cyclic sigh may help you feel calmer while one passes.

For partners, family and coworkers

• Believe her. Mood and sleep changes are not "in her head" and not a choice.
• Ask what would help. A cooler room, a quiet hour or help with chores can make a difference.
• Notice patterns without blame. "You seem worn out lately. Want to talk?" works better than "You're so moody."
• At work, small changes help: a fan, flexible breaks, or a later start after a bad night.
• If she seems hopeless or talks about not wanting to live, take it seriously and help her get support today. See worried about suicide.

Special situations

Early or surgical menopause. Menopause before 45 counts as early. Removing both ovaries causes menopause right away. Talk with a clinician about your options early.

A history of depression. If you have had depression before, tell your clinician at the start of perimenopause. Your past response to a medicine can guide the choice if depression returns.²

Breast cancer history. Some herbal products, such as St John's wort, can interact with breast cancer medicines like tamoxifen.³ Ask your cancer team before trying any treatment for menopause symptoms.

Common questions

Is this depression or just menopause?

It can be both. Menopause symptoms such as night sweats and poor sleep can lower mood. But if low mood lasts 2 weeks or more and affects daily life, it may be depression, which needs its own treatment.^1,2

Is hormone therapy safe now that the warnings changed?

The label changes reflect newer studies, especially of women who start before 60 or within 10 years of menopause.⁵ Hormone therapy still has risks for some people. The Menopause Society advises a personal review of your health and family history before starting.⁷

Will hormone therapy fix my brain fog?

Not usually. Hormone therapy is not recommended just to improve memory after natural menopause.¹ Better sleep, treating low mood, and staying active often help more.

Do I need a blood test to know I am in perimenopause?

Often not. For women over 45 with typical symptoms, clinicians can usually diagnose perimenopause without lab tests.³
