Women's Mental Health
PMDD, perimenopause and hormonal mood changes deserve a closer look.
If anxiety, irritability, low mood, brain fog or disrupted sleep seem to follow your cycle, appeared after pregnancy or began during your late 30s or 40s, the timing matters. We evaluate the complete pattern, including your psychiatric and medical history, menstrual changes, sleep, medications and targeted laboratory testing when clinically appropriate.

You may recognize yourself here.
Hormone-related mood changes do not look the same for every woman. Sometimes the timing provides the first important clue.
- Your anxiety, irritability, low mood or tearfulness predictably intensifies before your period and eases after it begins.
- You feel like yourself during part of the month and emotionally unfamiliar during another part.
- New anxiety, insomnia, brain fog or irritability appeared during your late 30s or 40s, even though you may still have regular periods.
- Your mood changed during pregnancy or after delivery and never fully returned to your previous baseline.
- Medication or therapy helped somewhat, but a cycle-related pattern remains.
- You have been told that these changes are simply part of being a woman, yet they are affecting your relationships, work or quality of life.
PMDD is often related to an increased sensitivity to normal hormonal changes. This means a hormone panel may appear normal. When PMDD is suspected, daily symptom tracking across at least two menstrual cycles can provide important diagnostic information.
Patterns We Evaluate
The timing of your symptoms matters.
Premenstrual Mood Changes and PMDD
Severe irritability, anxiety, depression, emotional sensitivity or loss of functioning that predictably appears before menstruation and improves after the period begins.
Postpartum Mood and Anxiety Changes
Depression, anxiety, intrusive thoughts, emotional disconnection or a persistent sense that you have not felt like yourself since pregnancy or delivery.
Perimenopause and Midlife Mood Changes
New or worsening anxiety, low mood, irritability, insomnia, brain fog or emotional sensitivity during the years leading to menopause.
A Thoughtful Evaluation
We look at the pattern, not one number.
There is no single laboratory test that diagnoses PMDD or reliably explains every perimenopausal mood change. Your evaluation begins with your symptom timeline, menstrual history, psychiatric and medical history, sleep, medications and daily functioning. Targeted laboratory testing may be ordered when clinically appropriate to evaluate contributing medical factors.
Your Pattern and Timeline
We review when symptoms began, whether they follow your menstrual cycle, how they affect your functioning and whether they changed during pregnancy, postpartum or perimenopause. Daily symptom tracking may be recommended when PMDD is suspected.
Targeted Medical Evaluation
When clinically indicated, testing may include thyroid function, iron and ferritin, vitamin B12, vitamin D, metabolic markers or selected reproductive hormones. Testing is individualized, and results are never interpreted in isolation.
A Coordinated Treatment Plan
Your plan may include psychotherapy, psychiatric medication management, sleep support, lifestyle guidance or coordination with your gynecologist, primary-care provider or another medical specialist.
Care built around your complete clinical picture.
A thoughtful treatment plan considers both psychiatric symptoms and the stage of life in which they appeared. Depending on your diagnosis, medical history and preferences, recommendations may include psychotherapy, medication, cycle-based treatment strategies, sleep support, lifestyle guidance or collaboration with another member of your medical team.
Medication is never assumed, dismissed or presented as the only option. Every recommendation is based on your symptoms, history, goals and clinical needs.

Common Questions
Questions women often ask.
Can perimenopause cause anxiety, depression or brain fog?
Hormonal fluctuations during perimenopause can coincide with changes in mood, sleep, concentration and anxiety. These symptoms can also have other psychiatric or medical causes, so a complete evaluation is important.
Is there a blood test for PMDD?
No single blood test diagnoses PMDD. Diagnosis depends primarily on the timing, severity and functional impact of symptoms. Daily symptom tracking across at least two menstrual cycles may be recommended.
Does every woman need hormone testing?
No. Laboratory testing is selected according to your symptoms, history and stage of life. Some women benefit from targeted testing, while others are better served by symptom tracking and a comprehensive clinical evaluation.
What may treatment include?
Treatment is individualized and may include psychotherapy, psychiatric medication management, cycle-based strategies, sleep and lifestyle support or coordination with gynecology or primary care.
Is this an insurance-based practice?
No. The Root Cause NP is a private-pay psychiatric practice and does not bill insurance. Current appointment fees are available on the Services page before care begins.
