Interview with Dr. Stacy Cohen, Psychiatrist Specializing in Reproductive Mental Health

Dr. Thais Aliabadi and Mary Alice Haney sat down with Dr. Stacy Cohen to reframe how we think about mood across the reproductive years. Her perspective: these emotional experiences are not “just in your head” but are deeply tied to hormonal rhythms, stress biology, and culture. Below we present an extended Q&A that walks through premenstrual dysphoric disorder, postpartum mood disorders, perimenopause and menopause, practical treatments, and how to advocate for better care.

Interview

What is PMDD, and how is it different from typical PMS?

PMDD stands for premenstrual dysphoric disorder. We say it is a severe, cyclical mood disorder tied to the luteal phase of the menstrual cycle. The hallmark is that symptoms reliably appear in the 10 days or so before bleeding and remit a few days after the period begins. That cyclical pattern is key.

PMS is common and often uncomfortable. PMDD is disabling. With PMDD, functioning is impaired. School and work performance dip, relationships fracture, impulsive behaviors or severe self-shame can arise, and people can feel like strangers to themselves. Importantly, the issue is usually not an absolute hormone deficit. Rather, it is the brain’s response to normal hormonal fluctuations that becomes dysregulated.

How can someone know whether their premenstrual symptoms are PMDD?

The first step is pattern recognition. We ask patients to track mood and functioning across at least two cycles. Highlight the “bad week” on a calendar. If the low mood, irritability, or functional impairment returns month after month in a predictable window, PMDD is likely.

Be aware of confounders. An IUD may stop bleeding but not the hormonal cycling: people can still have a luteal-phase mood dip even without visible menses. If the timing of symptoms varies widely, evaluate for other gynecologic issues such as PCOS or irregular ovulation.

What roles do stress and trauma play in PMDD?

Stress and trauma sensitize the nervous system. When the neuroendocrine system is on high alert, hormonal fluctuations exert outsized effects on mood. We see higher rates of PMDD among people with trauma histories or chronic stress. Cultural factors matter too: body dissatisfaction, performance pressure, and environments that punish normal menstrual changes can amplify distress.

Are there non-medication approaches that actually help?

Absolutely. One of the most underused strategies is practical scheduling. Treat the luteal week as your “rest week.” Block low-effort, low-stress activities on your calendar: a monthly massage, an evening to read the book you love, lighter workouts. That expectation reduces self-blame.

Dietary changes, sleep hygiene, and consistent movement are helpful. We also recommend magnesium and omega-3s as safe, low-risk adjuncts. The evidence base for a targeted “PMDD diet” supports lowering processed carbs and alcohol and emphasizing stable blood sugar and anti-inflammatory foods.

How does medication treatment for PMDD differ from treatment for non-cyclical depression?

This is where reproductive psychiatry gets interesting. Most antidepressants take four to six weeks to reach full effect when used continuously. For PMDD, we often use pulse dosing: short courses timed to the luteal phase. The brain’s neurosteroid environment during that phase makes selective serotonin reuptake inhibitors work much faster for PMDD.

Example regimens we use:

• Zoloft 25 to 50 mg daily from ovulation to menses (roughly day 14 to 28 in a 28-day cycle)
• Prozac 20 mg during the second half of the cycle
• For patients already on a daily SSRI, we might increase the dose during the luteal phase

This approach avoids continuous exposure for patients who prefer not to be on daily medication while still providing symptom relief.

 

Is there an FDA-approved medication specifically for PMDD?

Yes. The combined oral contraceptive drospirenone/ethinyl estradiol with a specific dosing schedule (often marketed as Yasmin or Yasmin-type formulations) is FDA-approved for PMDD. It works by flattening the hormonal fluctuations that trigger symptoms.

Not all birth control pills are the same for PMDD. Yasmin has evidence supporting the benefit for some patients because of its anti-androgenic progestin and the way it suppresses ovulation when used appropriately.

Postpartum mood and anxiety: biology and practical care

Why are the postpartum weeks so high-risk for mood symptoms?

Pregnancy supports a remarkably high hormonal state driven by the placenta. After delivery, the placenta and its hormonal support disappear quickly. That abrupt withdrawal—an exaggerated version of the luteal-phase hormone drop—can trigger mood and anxiety symptoms. We think of early postpartum blues as an exaggerated PMS: teary, irritable, and emotionally raw, and often resolving within six weeks.

Beyond six weeks, persistent detachment, inability to bond, intrusive thoughts about harm, or severe functional impairment must be taken seriously. Untreated postpartum depression can last months to years and affects both the parent and the infant’s early development.

What treatments are most effective for postpartum depression?

First-line treatments are the same classes we use for other major depressive and anxiety disorders: SSRIs and psychotherapy, especially trauma-informed modalities and behavioral therapies focused on sleep and routine. We always check for bipolar disorder because treating bipolar-related postpartum illness with an SSRI alone can be unsafe.

Two major innovations changed the landscape:

1. Rapid-acting hormonal modulators that target neurosteroid systems
2. Ketamine-assisted therapies for rapid symptom relief when needed

Tell us about the new hormonal medication for postpartum depression.

There is an approved medication that modulates the neurosteroid allopregnanolone. It is given as a short course—typically 14 days—and can produce dramatic improvement within days for some patients. The drug works by restoring GABAergic balance impacted by pregnancy-related hormone shifts.

Practical considerations:

• It can cause profound fatigue, and patients should not drive for at least 12 hours after dosing.
• It is typically reserved for moderate to severe cases and often requires prior trials of other antidepressants for insurance coverage.
• Access can be limited and cost can be high, so plan logistics in advance if this is an option.

 

How do you weigh breastfeeding, medications, and safety?

Our stance is evidence-based and pragmatic. Untreated depression or anxiety is a significant risk to both parent and baby. Many antidepressants are compatible with breastfeeding. We consider pharmacokinetics: during the second and third trimesters, blood volume increases, and medication concentrations can be diluted, requiring dose adjustments.

For stimulants (ADHD medication), the trade-offs are nuanced. If stopping a stimulant precipitates severe dysfunction, we discuss timing, short-acting options, and logistical strategies (pump and time the dose) rather than reflexively stopping treatment.

What about ketamine for postpartum depression?

Ketamine, especially IV or clinic-based protocols, can be life-changing for treatment-resistant or severe postpartum depression. It works quickly and promotes neuroplasticity, offering a reset when conventional options have failed or are too slow. Risks include dissociation, and there is potential for misuse, so we screen carefully for substance use history.

Perimenopause and menopause: the midlife hormone story

What is perimenopause, and when does it usually begin?

Perimenopause is the transition phase before menopause and often starts in the late 30s to early 40s. It can begin up to 7 to 10 years before the final menstrual period. Symptoms arise because hormone production becomes irregular: estrogen and progesterone levels fluctuate unpredictably.

Common symptoms include:

• Irregular bleeding
• Hot flashes and night sweats
• Sleep disturbance
• Brain fog and memory complaints
• Changes in mood, anxiety, and libido
• Vaginal dryness and recurrent infections

 

Why do so many women feel misunderstood by their doctors during perimenopause?

There are a few reasons. First, medical education has historically underemphasized female reproductive aging. Second, the Women’s Health Initiative cast a long shadow, and many patients and clinicians became fearful about hormone replacement therapy. Third, symptoms are heterogeneous: two women can be in perimenopause and have completely different complaints.

We need better primary care and OB-GYN education so that hormone-related cognitive and mood issues are recognized and treated appropriately instead of defaulting to polypharmacy with non-hormonal psychotropics.

When should we consider hormones in perimenopause?

Hormones are the gold standard for perimenopausal symptoms driven by low estrogen: hot flashes, night sweats, vaginal dryness, and significant sleep or cognitive changes. For women with a uterus, progesterone must accompany estrogen to protect the endometrium.

Options we commonly use:

• Oral contraceptives (for early perimenopause where contraception is still needed)
• Transdermal estrogen patches or gels (preferred delivery for steady levels and lower impact on clotting)
• Micronized progesterone at night to aid sleep and mood (100 mg at bedtime is a common starting point)
• Low-dose testosterone in certain cases to help libido and energy (topical application; doses are very small)

Are SSRIs ever appropriate during perimenopause?

Yes, SSRIs and SNRIs have a role. We use them when mood or anxiety symptoms are prominent or when hormones are contraindicated. SNRIs such as duloxetine (Symbalta) can be particularly helpful when pain, fibromyalgia-like symptoms, or significant somatic complaints accompany mood disturbances. But a key point: if hormones are the underlying driver, replacing them often provides more targeted relief with fewer trade-offs for libido and emotional range.

How do you approach a patient who has been on the same antidepressant for years?

We reassess. Many people start an antidepressant in adolescence or early adulthood and remain on it unquestioningly. The STARD trial and clinical experience suggest that a significant proportion of people have a single episode and could consider tapering after sustained remission with careful monitoring.

Steps we recommend:

1. Quarterly or monthly psychiatric follow-up during changes
2. Consider a slow taper when life stress is stable
3. Pair taper attempts with psychotherapy and lifestyle supports

Never stop abruptly. Withdrawal from antidepressants can be clinically significant and requires a graded reduction.

Tools we recommend: supplements, nervous system work, and practical tips

Which supplements are useful across the reproductive timeline?

Our routine recommendations include:

• Magnesium L-threonate for sleep and anxiety; it crosses the blood-brain barrier
• Omega-3 fatty acids for mood and cognitive health
• Micronized progesterone at night in perimenopausal mood and sleep disturbance

These are adjuncts, not cures, but they are low risk and often helpful.

What does nervous system regulation look like in practice?

We use polyvagal-informed approaches to help patients understand when their nervous system is stuck in fight-or-flight. Simple, practical tools can shift state:

• Breathwork and paced breathing
• Progressive muscle relaxation
• Grounding exercises and consistent sleep routines

These strategies reduce baseline arousal and make hormonal treatments and medications more effective.

How should partners and families be involved?

Education is essential. Partners often do not understand the biological drivers of mood and libido changes. We encourage partners to attend visits or at least review educational materials. When partners understand the physiology, relationship stress often improves quickly because blame and misinterpretation lessen.

Access and advocacy: what to do if specialty care is hard to find

What can patients do when psychiatry wait times are long?

We recommend a multi-pronged plan:

• Ask your primary care provider for a psychiatric referral and a clear medication plan for the interim
• Use telehealth platforms with credentialed psychiatrists who accept insurance
• Consider a single specialist consultation to create a care plan that your primary team can follow
• Seek clinics that employ psychiatrists who supervise nurse practitioners and physician assistants—this model increases access

Be an informed patient. Ask how long you should remain on a medication, what outcomes to expect in 6 weeks, and what follow-up is planned.

 

Practical checklists and red flags

PMDD checklist

• Symptoms recur in the same luteal window each month
• Marked impairment in work, school, or relationships
• Symptoms remit shortly after menses begins
• Try calendar tracking for two cycles before concluding

Postpartum red flags

• Persistent detachment from the baby beyond six weeks
• Intrusive thoughts that cause distress (report them; they do not mean you are dangerous)
• Inability to care for self or baby due to depression or anxiety
• Severe sleep disturbance or psychotic symptoms—seek urgent care

Perimenopause red flags

• New or worsening mood swings with irregular cycles
• Significant sexual dysfunction or vaginal dryness affecting relationships
• Hot flashes, night sweats, and brain fog that impair daytime functioning
• Rapid symptom onset that interferes with daily life—consider hormone evaluation

Resources we trust

• The Moment Health — reproductive psychiatry resources and guidance
• Menopause.org — directory of certified menopause providers and patient education
• Find a reproductive psychiatrist for complex cases. If access is limited, ask for a one-time consult to set a plan.

Rapid-fire practical answers

• Coffee and PMDD — Reduce or avoid. Caffeine can amplify anxiety and worsen symptoms.
• Exercise during the luteal phase — Yes, but keep it light to moderate; avoid forcing intense workouts when fatigued.
• One supplement every woman should consider — Magnesium L-threonate plus omega-3s.
• Testosterone for women — Underutilized in appropriate cases. Small topical doses can improve libido and energy for some patients.
• Magnesium for PMS — We call it “magic” for many patients, especially for sleep and anxiety.

Final practical takeaways

We want to leave you with a few concrete action items:

1. Track your cycle and mood for at least two cycles. Knowing the pattern changes everything.
2. If you are pregnant or planning pregnancy and have current or past mood disorders, create a peripartum plan with a clinician in advance.
3. If you suspect PMDD, ask about pulse SSRI dosing or an oral contraceptive with proven benefit. If you suspect postpartum depression, ask about rapid-acting options and ensure safe supports are in place for the first two weeks of any new treatment.
4. For perimenopause symptoms, consider a trial of micronized progesterone at night for sleep and mood, and explore estrogen replacement when appropriate.
5. Be your own advocate. If a medication or approach isn’t helping, ask for re-evaluation and a second opinion.

Frequently asked questions

How do I tell PMDD from regular PMS?

PMDD causes severe mood and functional impairment with a predictable luteal-phase timing and remission after menses. Track symptoms over two cycles and note whether your ability to work, study, or maintain relationships is affected.

Is it safe to take antidepressants during pregnancy?

Many antidepressants are compatible with pregnancy. Untreated depression and anxiety pose significant risks to both parent and fetus, so we weigh the risks of treatment versus non-treatment and adjust doses as pregnancy physiology changes.

What is the 14-day medication for postpartum depression?

There is an approved neurosteroid (allopregnanolone) modulator given as a short course to target postpartum depression. It can act rapidly but causes sedation in many patients and requires planning for safe administration.

Will hormones cure my mood symptoms in perimenopause?

Hormone therapy can be highly effective when low or fluctuating estrogen is the primary driver of symptoms such as hot flashes, sleep disruption, brain fog, and libido changes. Progesterone at night often helps mood and sleep. Individualized care matters.

Can I stop my antidepressant after a single episode?

Possibly. For many people, a prescribed course of six months to one year is sufficient after remission, and some never need to restart. Decisions should be guided by psychiatric follow-up and a gradual taper plan.

Closing note

Our view is simple: hormones shape mood, but they do not define destiny. With awareness, tracking, targeted treatments, and nervous system care, the months and years that feel unmanageable can become manageable again. If anything here resonates, speak up with your clinician, ask the right questions, and seek the care that matches the pattern you are experiencing.
