What to tell your doctor about brain fog: a checklist

Short answer: To get the most from a doctor's visit about brain fog, bring specifics: when it started, how often it happens, concrete examples, what it affects at work and home, your period and sleep changes, your mood, every medication and supplement you take, and your family history. Say clearly that you think it may be perimenopause, and ask which other causes should be ruled out.

Appointments are short, and brain fog is hard to describe on the spot, especially when it is one of the things affecting you. A checklist helps.

Before you go: write down

When it started, and whether it is steady, worsening or coming and going.
Three real examples. "I lost the word for stapler in a meeting." "I drove to the wrong school." Specifics are taken more seriously than "I feel foggy".
What it affects: work, driving, conversations, reading.
Your periods: dates of the last few, and any change in flow, pain or timing.
Your sleep: how often you wake, night sweats, snoring.
Your mood: anxiety, low mood, irritability.
Other symptoms: hot flashes, joint aches, headaches, palpitations, tiredness.
Medications and supplements, all of them, with doses.
Family history: early menopause, thyroid disease, dementia before 65.

In the appointment: say

"I think this may be perimenopause." Naming it helps the conversation start in the right place.
"This is affecting my work." It tells your doctor the impact is real.
"What else should we rule out?" Ask about thyroid, iron, B12 and blood sugar.
"What are my options?" Ask about both hormonal and non hormonal treatment, and about sleep.

Signs to mention right away

Tell your doctor promptly if you are getting lost in familiar places, struggling with tasks you used to do easily, repeating the same question in one conversation, if people close to you are worried, or if anyone in your family had dementia before 65.

Afterwards

Write down what was agreed and when to review.
Keep tracking, so the next visit starts with data.
