Brain fog at 45 isn't automatically perimenopause.
It isn't automatically anything.
The conversation around midlife symptoms can swing between two extremes: everything is hormones, or none of it is. Neither gives women the full picture.
Hormonal shifts may matter, and they deserve to be taken seriously. So do sleep, stress, medications, thyroid function, iron, mood, and other factors that can affect how clearly the brain is functioning.
The goal isn't to dismiss perimenopause.
It's to avoid stopping at the first explanation that fits.
One symptom can have several inputs. Thoughtful care looks at how they may be interacting.
