Does Perimenopause Cause Mood Changes?
Does Perimenopause Cause Depression? Yes — Here's Why
You might notice depressed mood, irritability, tearfulness, loss of interest in things you used to enjoy, and a persistent sense of flatness that feels out of character. As estrogen and progesterone fluctuate, they directly affect serotonin and dopamine — the neurotransmitters that regulate mood, motivation, and emotional stability. These symptoms are biologically driven, medically recognized, and — importantly — treatable. You don't have to white-knuckle through 7–10 years of perimenopause waiting for it to resolve on its own.
Why Does Perimenopause Cause Mood Swings and Depression?
Perimenopause causes mood changes because hormone fluctuations (especially estrogen and progesterone) can affect neurotransmitters in our brains like:
Serotonin, which helps regulate mood and emotional stability
Dopamine, which affects motivation and pleasure
As hormone levels rise and fall unpredictably during perimenopause, the brain’s ability to manage mood can be disrupted—leading to new or intensified depressive symptoms. Medical and mental health professionals recognize mood symptoms as a common and normal part of the perimenopausal transition, even in people with no history of depression. But just because it’s normal doesn’t mean you have to suffer through. You have options!
Perimenopause Depression Symptoms: What to Look For
There are 34 documented symptoms of perimenopause. Seven of them can be associated with depression: 1) depressed mood, 2) difficulty concentrating, 3) fatigue, 4) irritability, 5) libido changes- related to motivation, pleasure, interest, 6) mood swings, and 7) sleep issues.
Mood changes and depressive symptoms during perimenopause can be experienced as cognitive (thoughts), emotional (feelings), behavioral (how we act, react), or physical (how we feel in our body), or any combination. These symptoms may appear suddenly and vary in intensity over time.
Symptoms of perimenopause depression can include:
Changes in mood (depressed mood) or mood swings
Increased sadness and tearfulness
Increased irritability or irritable mood
Loss of interest or pleasure in activities you used to enjoy
Weight loss or gain, decreased or increased appetite
Insomnia and consequent fatigue or loss of energy
Feelings of worthlessness or excessive guilt
Difficulty concentrating or indecisiveness
Are Perimenopause Mood Changes the Same as Clinical Depression?
Yes… and no. Perimenopausal mood changes (e.g. depressed mood) can be symptoms of diagnosable depressive disorders, but among other diagnostic criteria, experiencing a depressed mood here and there is not the same as experiencing depressed mood coupled with feelings of sadness, emptiness, or hopelessness consistently for a period of at least two weeks, which represent a change from previous functioning and is accompanied by several other symptoms in that same two-week time frame.
Perimenopause-related mood changes are not always the same as depression in that they:
Fluctuate over time
Are often linked to hormonal shifts
May improve as hormones stabilize
Can respond positively to hormonal or lifestyle support
Perimenopause and Depression: Three Depressive Disorders to Know
Clinical depression aka Major Depressive Disorder:
Five or more of the following symptoms are present during the same two week period and represent a change from previous functioning: depressed mood, loss of interest or pleasure in activities, weight loss/gain or decrease/increase in appetite, insomnia/hypersomnia, agitation or feeling slowed down, fatigue or loss of energy, feelings of worthlessness or excessive guilt, difficulty concentrating or indecisiveness, and/or recurrent thoughts of death or suicidal ideation.

Persistent Depressive Disorder (Formerly Dysthymia)
While a major depressive episode can come on abruptly, intensely, and last no less than two weeks, the symptoms of persistent depressive disorder are bothersome more days than not for at least two years. Symptoms accompanying depressed mood can include: Poor appetite or over, eating, insomnia, or hypersomnia, low energy, or fatigue, low self-esteem, poor concentration, or difficulty making decisions, feelings of hopelessness.
Premenstrual Dysphoric Disorder
In the majority of a woman’s cycles, at least five symptoms must be present in the final week before the onset of her period, and become minimal or absent in the week after her period ends: mood swings; irritability or anger, depressed mood, feelings of hopelessness, or self-deprecating thoughts; anxiety, tension, or feeling on edge; decreased interest; difficulty concentrating; lethargy, or lack of energy; changes in appetite; hypersomnia, or insomnia; feeling, overwhelmed or out of control; and physical symptoms like swelling, pain, bloating or weight gain.
If you have experienced any combination of any of the above symptoms during the perimenopause transition, it likely means you’ve experienced some normal mood changes associated with this time of life. A mental healthcare provider can help distinguish between normal perimenopause mood changes and diagnosable depressive disorders.
When Are Perimenopause Mood Changes Normal — and When Are They Not?
Experiencing emotional changes during perimenopause does not mean something is “wrong.” Mood changes during perimenopause are generally considered normal when they:
Come and go rather than stay constant
Occur in tandem with cycle changes
Improve with rest, stress reduction, or support
Do not interfere with daily life or functioning
What Helps With Perimenopause Mood Changes — Right Now, Today
These are the same places I'd start with clients — think of this as a preview of our work together. You don't have to white-knuckle your way through years of this alone. If your mood has felt flat, heavy, or not-yourself for a while now, schedule a free 20-minute consultation -> No pressure, just a conversation about what would help.
Name what you're feeling — specifically
Do you "feel flat and unmotivated?" Or do you "feel irritable and easily overwhelmed." The more specific you can be about what you're experiencing, the more clearly you can identify what might help. A mood-tracking app or a simple daily note on your phone — one sentence about how you felt and what was happening — builds the pattern recognition that makes perimenopausal mood changes feel less random and more manageable.
Move — especially when you don't want to
Depression and low mood reduce motivation for the very activities that improve mood — movement, social connection, engagement. One way through it is behavioral activation — doing the mood-lifting activity before you feel like doing it, rather than waiting until you feel like it. A 20-minute walk, even a reluctant one, can shift mood through serotonin and dopamine release. Start with the smallest version of the activity you can commit to.
Get outside — specifically in natural light
Sunlight exposure in the morning — even 10-20 minutes — supports serotonin production and helps regulate the circadian rhythm that perimenopause is disrupting. This is not the same as exercise, though the two can be combined. Sitting outside with morning coffee counts. A short walk counts. The light itself is the intervention.
Eat to support your neurochemistry
Serotonin is produced in the gut — approximately 90% of your body's serotonin is made there. A diet rich in fiber, fermented foods, and omega-3 fatty acids supports gut health and, through it, serotonin production. Foods high in tryptophan — the amino acid serotonin is made from — include eggs, turkey, salmon, nuts, and seeds. Give your brain the raw materials it needs to make the neurotransmitters that perimenopause is depleting.
Reduce alcohol — especially if you're using it to cope with low mood
Alcohol is a depressant that depletes serotonin and dopamine — the same neurotransmitters that perimenopause is already compromising. Using alcohol to manage low mood creates a short-term lift and a longer-term deficit. If you notice your mood is consistently worse the day after drinking, that's important clinical information worth acting on.
Connect — even briefly, even when it's hard
Social withdrawal is both a symptom of depression and a driver of it. Isolation reduces the oxytocin and serotonin that come from genuine human connection. You don't need to perform wellness for other people — you need contact. A text to a friend. A phone call. Sitting in a coffee shop. The minimum effective dose of connection is smaller than depression tells you it is.
Consider whether this needs medical attention
If low mood has been present most days for more than two weeks, is significantly affecting your functioning — reach out to your doctor or a mental health professional. Perimenopause mood symptoms are real, biological, and treatable. You don't have to manage them alone
When to Seek Professional Support for Perimenopause Depression
There is never a “wrong” time to see a therapist. You should talk to a therapist or healthcare professional if mood changes:
Interfere with functioning at home, in your relationships, at work, or at school
Feel overwhelming or unmanageable
Last most days for more than two weeks
Are accompanied by severe anxiety or emotional withdrawal
Working with a therapist can help you determine whether symptoms are hormonally driven, mental health–related, or both.
Psychotherapy offers compassionate, evidence-based support tailored to this unique stage of life. With the right support, midlife can become not just something to survive—but a transition that leads to greater clarity, authenticity, and emotional resilience.
