Brain Fog in Perimenopause: Why Your Brain Feels Off (and What Helps)
“I lose words all the time.”
My patient said this in a meeting… then immediately spiraled.
Because it’s not just the word.
It’s the pause.
The blank.
The moment where you know something was there, and now it’s gone.
And the thought that follows:
What is wrong with me?
When Your Brain Doesn’t Feel Like Yours
I hear this constantly.
Women who feel like their brain just isn’t working the way it used to.
They forget things.
Lose their train of thought.
Start saying no to opportunities; not because they can’t do them, but because they’re afraid of looking… off.
Not as sharp.
Not as capable.
Not like themselves.
That’s the part that really gets to people.
What’s Actually Happening
Most of the time, nothing is structurally wrong with your brain.
But functionally? Things are different.
Estrogen affects neurotransmitters like dopamine and serotonin impacting systems that support focus, motivation, and clear thinking.
So when estrogen starts fluctuating, your brain can feel like it’s not working right.
You’re paying attention.
But your brain isn’t cooperating when it comes to:
finding words
staying on track
holding onto thoughts long enough to use them
Add sleep issues, stress, and the general demands of midlife and now you’ve got a high-performing brain with less reliable support.
Is This ADHD or Something Else?
This is also why so many women suddenly wonder if they have ADHD.
And sometimes they do.
But a lot of the time, it’s a combination of:
hormonal shifts
increased mental load
disrupted sleep
…showing up in a very similar way.
Why Brain Fog Feels So Scary
Brain fog isn’t just frustrating.
It’s visible.
It shows up in meetings.
Conversations.
Presentations.
Not just in your own head, but out loud, in real time.
And over time, that can chip away at something bigger: Confidence.
You start pulling back.
Playing smaller.
Saying no to things you would’ve said yes to before.
Not because you’re less capable, but because you don’t trust your brain the same way.
Drawing symptoms is one of my coping mechanisms!
“Is This Dementia?”
This is the question a lot of women don’t say out loud, but definitely think.
And it’s understandable.
But in many cases, brain fog during perimenopause is temporary.
It can last for a while.
It can be frustrating.
It can absolutely shake your confidence.
But it is not the same as progressive cognitive decline.
For many women, things improve and stabilize again after menopause.
Getting older does not automatically mean losing your edge.
What Actually Helps
Not pushing harder.
Supporting your brain differently.
A few simple shifts go a long way:
Prioritize sleep (as much as possible)
Get things out of your head onto your calendar, notes, reminders
Let the list remember for you
Notice patterns; when it’s worse, when it’s better
This isn’t giving up. It’s adapting.
A Very Real Example
Personally, I fully lean into lists.
Calendar + notes app + random scraps of paper that may or may not make sense later.
I check them constantly, especially before bed so I don’t wake up at 3am trying to remember something important like… did I schedule my kids' 6 month dental visit.
Again.
As a teen I used to make fun of my mom for repeating things and forgetting conversations. I thought she just wasn't paying attention.
And now?
I have absolutely no memory of saying things I apparently said. It's most obvious when I recommend we watch movies that my whole family jokingly confirms we've already watched. (We could never send my mom to the video store for the same reason!!)
So. That’s going well.
Your Brain Didn’t Break
Brain fog in perimenopause is annoying.
It’s embarrassing.
It can mess with your confidence.
But it is not your brain failing.
It’s your brain working under different conditions.
