The Rage and Brain Fog Takeover

Medically Reviewed by Smitha Bhandari, MD on April 03, 2026

If you’re of a certain age, you may be noticing signs of perimenopause, the long transition into menopause. Or you might already be there.

If you have major depressive disorder — and even if you don’t — it’s important to recognize this time as a “window of vulnerability,” says Rajita Patil, MD, director of UCLA Health’s Comprehensive Menopause Care program.

“During this time frame, we see a spike in clinical mental health symptoms and disorders,” she says. “The number one reason is hormonal changes that are happening, especially estrogen decline or fluctuation. It has a profound impact on neurotransmitters in the brain.”

Mental health challenges during perimenopause are more likely if you have a history of depression — especially postpartum — or premenstrual syndrome (PMS), says Mary Jane Minkin, MD, a practicing gynecologist and clinical professor at Yale School of Medicine and a North American Menopause Society certified menopause clinician.

The good news is that there are ways to manage these changes. Here’s what you need to know.

Signs You’re in Perimenopause or Menopause

First, let’s detail what perimenopause or menopause looks like:

Common symptoms include:

Irregular periods
Lower sexual desire
Hot flashes
Night sweats
Insomnia (trouble sleeping)
Brain fog

You might also deal with:

Mood swings
Irritability
Depression

How Your Brain Changes

Research has shown the menopause transition is highly dynamic. The shifts in your hormones can affect your brain:

Structure
Connectivity
Metabolism

These changes can worsen or lead to depression.

Rage and Brain Fog

The transition into menopause may also come with brain fog that leaves you feeling like your mind is fuzzy or “cotton wool.” You might:

Forget names or other details
Miss appointments
Lose your phone or keys a lot
Struggle to pay attention while reading or watching TV
Have trouble functioning at work

You may notice changes in your mood, too. You might be:

Less patient
Easily frustrated or “set off”
Irritable

As these feelings pile up, you could find yourself exploding in rage. The Seattle Midlife Women’s Health Study surveyed 500 women of ages 35-55 about their experiences with anger. They asked them to rank:

Their intensity of angry feelings at particular times
How prone they were to anger
Their tendency to experience or express anger indiscriminately
Their expression of anger following criticism or unfair treatment
How often they bottled up angry feelings
How often they expressed aggressive or angry behavior toward other people or objects
How often they tried to control anger

Overall, the study found that anger intensity and frequency tended to go up with age. But anger control did, too, suggesting many women in perimenopause feel the emotion more often but put a lot of energy into not showing it.

Other Factors That Contribute to Depression, Rage, and Brain Fog

Mental health challenges during perimenopause likely involve a wide range of circumstances and factors, including insomnia and trouble sleeping.

“It can be hormone or vasomotor symptoms that cause wakefulness and prevent deep restorative sleep,” Patil says. “It’s not so much sleep duration, but with frequent awakenings, the body doesn’t feel rested.”

Vasomotor symptoms, more commonly known as hot flashes, can affect your mood, too. All this is likely happening when you’re dealing with unique psychosocial stressors. You may be working full-time and in the most advanced stage of your career. You might also have children at home while caring for aging parents. Or you could be facing “empty nest syndrome” if your children have grown up and moved away.

“You may have been feeling like superwoman, then this happens: [Changes in your] hormones and sleep and hot flashes. It all comes crashing.”

Treating Your Mental Health Symptoms in Perimenopause

The first thing you need to know is that depression, brain fog, and rage aren’t your fault. And they aren’t signs of a personality flaw. More importantly, you don’t have to suffer through it.

“People think these are natural symptoms and something you have to put up with, or they have a false sense that there’s a lack of effective or safe treatment,” says Ekta Kapoor, MBBS, an endocrinologist and menopause expert at Mayo Clinic.

If your primary care doctor or gynecologist doesn’t take your concerns seriously, consider seeing a doctor who specializes in menopause or who is a certified menopause practitioner.

Patil says it’s important to address the whole person. Healthy lifestyle changes are key, and quality sleep is a top priority.

“When we get good sleep, inflammation decreases in our organs,” she says. “Focus on making sure we optimize sleep, whether it’s treating vasomotor symptoms or sleep hygiene, we have to do all the things we can do to minimize sleep disruption.”

To improve sleep, Patil recommends that you:

Avoid alcohol
Minimize your use of digital devices
Practice mind-body relaxation techniques
Exercise regularly

If stressors at home or work are keeping you up, consider seeing a therapist who can help, Patil says.

Studies show that cognitive behavioral therapy (CBT) can lessen hot flashes and improve sleep while boosting your mood and quality of life. Medications can also help. These include:

Hormone therapy, such as estrogen patches or pills
Birth control pills
Antidepressants
Nonhormonal medicines for hot flashes, such as fezolinetant (Veozah)

Minkin says antidepressants such as selective serotonin reuptake inhibitors (SSRIs) can also help with hot flashes and “give you a mood break.” Research suggests combining antidepressants with estrogen therapy may lead to better responses during perimenopause.
