What is happening
These three complaints get lumped together because they often arrive together, but they have different causes and different treatments. Separating them is the single most useful thing a visit can do.
Sleep disruption during menopause has several possible drivers. Night sweats fragment sleep directly. Primary insomnia — difficulty falling or staying asleep independent of heat — becomes more common with age in everyone. Sleep apnea rises sharply in women after menopause and is systematically underdiagnosed, partly because the classic picture people have in mind is a heavy snoring man. Anxiety and depression disrupt sleep. So does alcohol, which helps you fall asleep and then wakes you four hours later.
Mood is similarly layered. The perimenopausal transition carries a genuinely increased risk of depressive episodes, particularly in women with a history of depression or of premenstrual mood symptoms. Sleep deprivation worsens mood on its own. And life at this age frequently supplies its own reasons.
Cognitive complaints are the most misunderstood. Longitudinal studies do find measurable changes in verbal memory and processing speed during the transition, and they tend to improve afterward. Poor sleep, hot flashes, anxiety, and depression all impair attention, which is what most “brain fog” turns out to be.
What we will and will not claim
Hormone therapy improves sleep when vasomotor symptoms are the reason you wake. That is supported and that is the claim we make.
We do not tell women that hormone therapy will lift their mood, sharpen their memory, restore their energy, or protect them from dementia. Those claims outrun the evidence, and prescribing on them means missing depression, sleep apnea, thyroid disease, anemia, and medication side effects that are treatable.
How we approach it
We ask what wakes you, and when. Heat at 3am points somewhere different from lying awake at 11pm.
We screen for depression and anxiety with a standard questionnaire, because subjective impressions are unreliable in both directions. We ask about snoring, witnessed apneas, and daytime sleepiness, and we refer for a sleep study when the answers warrant it. We check thyroid function, iron studies, and vitamin B12 when the history supports it, and we review your medication list, since several common medications disrupt sleep.
Then we treat what we found. If night sweats are the problem, treating them is the treatment. If it is insomnia, we point you to CBT-I. If it is depression, we treat depression. If it is apnea, no hormone will fix it.
