If you are in your mid-to late-40s and feel completely exhausted, unusually irritable, or suddenly overwhelmed by anxiety, you might visit your primary care provider looking for answers. Far too often, women in this position walk out of the clinic with a brand-new prescription for an antidepressant.
But a groundbreaking new medical study suggests that for millions of women, these symptoms aren’t a primary mental health condition at all – they are the first, unrecognized signs of perimenopause.
In a large joint study recently published in the journal Menopause (1), researchers from the Mayo Clinic and Flo Health analyzed data from more than 17,000 women globally to track the symptoms that women expect during perimenopause versus what they actually experience. The results exposed a massive knowledge gap:
- The Expectation: 71% of women anticipate hot flashes to be the primary hallmark of entering perimenopause.
- The Reality: The most prevalent real-world symptoms are cognitive and emotional. An overwhelming 83% of women experience fatigue and mental exhaustion, 80% battle severe irritability and 77% report depressive moods and anxiety.
Because public health messaging has taught us to wait for hot flashes and irregular menstrual periods, women – and their doctors – frequently fail to connect these profound mood and energy changes to fluctuating reproductive hormones.
Why This Gap Leads to Misdiagnosis
A follow-up paper published by The Menopause Society (2) revealed that nearly half of women over the age of 40 are entirely unsure whether they have entered perimenopause. When the authors looked at why women are so confused, the main reason is that many of them don’t realize that menopause involves much more than their menstrual periods stopping. They assume they are just suffering from corporate burnout, stress or a late-onset mental health issue because their menstrual cycles are still completely regular.
Unfortunately, many physicians and other health care providers don’t realize this either! Without a definitive blood test for perimenopause, clinicians frequently sort these overlapping emotional and physical symptoms into the most familiar diagnostic boxes they know: depression and generalized anxiety disorder. As a result, women are routinely prescribed behavioral health medications while the underlying hormonal transition goes entirely untreated.
Navigating the Transition: What You Can Do
Perimenopause can begin up to a decade before your final period, and neurological symptoms almost always precede changes to your menstrual cycle. If you feel “off,” you are not imagining it, and you are certainly not alone.
To protect your health and advocate for yourself at your next appointment, consider taking these important steps:
- Monitor ALL your symptoms: Don’t just track your period. Keep a daily log of sleep quality, fatigue levels, sudden mood shifts and digestive changes.
- Look for patterns: Hormonal mental exhaustion has a cyclical, unpredictable ebb and flow that looks very different from clinical, situational depression.
- Seek certified care: If you suspect your symptoms are hormonal, consult a provider specializing specifically in midlife women’s health who can look at your health holistically.
