- Tension: Women in midlife are being handed depression and anxiety diagnoses when their real condition — sleep apnea — presents with symptoms that perfectly mimic mental health disorders.
- Noise: Outdated clinical screening tools built on male symptom profiles, diagnostic anchoring, and the overlap between sleep deprivation and mood disorders create a perfect storm of misdiagnosis that can persist for years.
- Direct Message: The cruelest part of this misdiagnosis isn’t the delayed treatment — it’s that it convinces women their suffering is a psychological failing, when it’s a treatable breathing disorder that nobody thought to look for.

Diane Kowalski, 53, a school librarian in Naperville, Illinois, sat in her doctor’s office last March and listened to a diagnosis that made perfect sense on paper. Depression, her physician said. Maybe generalized anxiety. The symptoms lined up — the crushing fatigue that no amount of sleep could fix, the brain fog that made cataloging new arrivals feel like translating ancient Greek, the irritability that had started fraying her marriage. She left with a prescription for sertraline and a referral to a therapist. Six months and two dosage increases later, she felt exactly the same.
It wasn’t until her dentist — her dentist — noticed signs of nighttime teeth grinding and asked about her sleep that anyone thought to look in a different direction. A sleep study revealed moderate obstructive sleep apnea. Diane had been stopping breathing an average of 22 times per hour, every single night, for what was likely years.
“I wasn’t depressed,” she told me. “I was suffocating in my sleep and nobody thought to check.”
Her story is disturbingly common. And the more you look at the data, the more it starts to feel less like a series of individual misdiagnoses and more like a systemic failure with a very specific face — women in midlife.
Sleep apnea has long been coded as a male condition. The stereotypical patient is overweight, middle-aged, male, and snores like a freight train. Clinical screening tools were largely developed using male symptom profiles. But as we’ve explored before, women over 50 are now being diagnosed at record rates precisely because the medical establishment spent decades looking for the wrong presentation. Women with sleep apnea are less likely to report the thunderous snoring that triggers a referral. Instead, they report fatigue, mood disturbance, insomnia, and morning headaches — symptoms that map almost perfectly onto depression and anxiety screening questionnaires.
A 2017 review in Sleep Medicine Reviews found that women with obstructive sleep apnea were significantly more likely than men to receive an initial diagnosis of depression, insomnia, or a psychosomatic condition before their breathing disorder was identified. The delay wasn’t a matter of weeks. It averaged years.
Dr. Neha Pathak, a pulmonologist in Atlanta who now specializes in sleep disorders in women, calls this the “symptom translation problem.” Men walk in and say they snore and can’t stay awake during meetings. Women walk in and say they feel like they’re falling apart. “The same disease speaks a different language depending on who has it,” she says. “And we’ve only been trained to understand one dialect.”
Consider what happened to Teresa Gallegos, 58, an office manager in Albuquerque. She’d been on antidepressants for four years when her adult daughter — a nursing student — brought home a textbook chapter on sleep-disordered breathing in postmenopausal women. The risk factors read like Teresa’s biography: the weight gain that had crept on after menopause, the restless nights, the blood pressure that had started climbing despite medication. Doctors had been looking for the wrong symptoms the entire time. Teresa pushed for a sleep study. Her apnea-hypopnea index came back at 31 — firmly in the moderate-to-severe range. Within three months of starting CPAP therapy, she tapered off the antidepressant she’d never needed in the first place.
The biological mechanism connecting menopause and sleep apnea is well-established. Estrogen and progesterone help maintain upper airway muscle tone during sleep. As those hormones decline — sharply, for many women — the airway becomes more collapsible. A study published in Chest found that postmenopausal women who were not on hormone replacement therapy had a significantly higher prevalence of sleep-disordered breathing than premenopausal women. The hormonal shift doesn’t just change mood and metabolism — it literally changes the architecture of breathing during sleep.
But here’s where it gets tangled. Sleep deprivation does cause depression and anxiety. Chronic fragmented sleep — the kind produced by dozens of micro-awakenings per hour — disrupts serotonin regulation, impairs prefrontal cortex function, and elevates cortisol. So when a woman walks into a clinic reporting mood symptoms, she’s not making them up. She genuinely feels depressed. She genuinely feels anxious. The symptoms are real. The question is whether they’re the disease or the downstream consequence of something else entirely.
This is what researchers call diagnostic anchoring — the tendency to lock onto the first plausible explanation and stop looking. When a 54-year-old woman reports persistent fatigue, low mood, and difficulty concentrating, the mental health framework snaps into place almost automatically. The PHQ-9 depression screening comes out. The GAD-7 anxiety scale follows. An SSRI prescription gets written. And because these medications sometimes slightly improve sleep quality as a side effect, there may even be a brief, modest improvement that reinforces the wrong diagnosis.
Marcus DeLeon, 61, a retired firefighter in San Antonio, watched this cycle consume his wife, Patricia, for nearly three years. “She kept going back saying the medication wasn’t working right,” he said. “They’d switch her to something else or add something. Nobody once asked her to describe what her nights actually looked like.” It was Marcus who finally recorded Patricia sleeping on his phone — not snoring, but gasping, with long pauses that terrified him. That recording, played for a new physician during a walk-in appointment, got her a sleep referral within the week.
The pattern echoes something we’ve seen in other areas of health — the well-intentioned intervention that addresses the surface while the real cause goes untreated. Women take supplements for brain fog. They try meditation apps for the anxiety. They blame themselves for not having the discipline to exercise through the exhaustion. It’s the same quiet self-blame that surfaces when people discover that the problem was never willpower — it was biology that nobody thought to investigate.
Dr. Pathak estimates that among her female patients over 50 who are eventually diagnosed with sleep apnea, roughly 40 percent arrived with an existing prescription for an antidepressant or anti-anxiety medication. “I’m not saying those medications don’t help people who need them,” she’s careful to note. “I’m saying we owe women a complete workup before we decide what they need.”
There’s a particular cruelty to this kind of misdiagnosis. It doesn’t just delay treatment — it rewrites a woman’s understanding of herself. Diane Kowalski spent six months believing her brain had betrayed her, that something fundamental in her psychology had broken. Teresa Gallegos internalized four years of feeling like she couldn’t manage a condition that, it turned out, she never had. The antidepressant that doesn’t work becomes its own source of shame — why can’t I get better? — and that shame echoes the isolation that so many people in midlife already feel, the quiet crisis of not wanting to burden anyone with the weight of what you’re carrying.
What makes this fixable is also what makes it so frustrating — sleep apnea is not a mysterious condition. It’s one of the most well-understood, most treatable disorders in medicine. A home sleep test costs a fraction of months of psychiatric visits and medication trials. The technology exists. The knowledge exists. What’s missing is the reflex to consider it when the patient doesn’t match the outdated archetype.
Diane uses a CPAP machine now. She sleeps through the night for the first time in years. The brain fog cleared within weeks. The irritability softened. Her husband noticed the change before she fully did. She’s off the sertraline completely.
“I keep thinking about all those months,” she said. “Not angry, exactly. Just — tired of a different kind. Tired of having to be the one who figures it out.”
That might be the part that lingers most. Not that the medical system failed these women, though it did. Not that the diagnostic tools were biased, though they were. But that so many women sat with a label that told them their suffering was coming from inside their own minds — when it was coming from their own airways. And the difference between those two things is not subtle. It is the difference between a problem you manage and a problem you solve. Between years of coping and the first full night of actual rest.
