Air
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
I want to check whether indoor air quality or a building exposure is contributing to my brain fog. The strongest clue is that my cognition changes by location or ventilation, not just by sleep or meals.
What would weaken it
- -Does the fog reliably worsen in a specific room, building, car, or smoke exposure and improve outdoors?
- -Is the strongest trigger stale air, smoke, chemical odors, or wildfire days rather than snoring or meal timing?
- -Do symptoms lift after fresh air, a window, or leaving the space?
- -Could bedroom CO2 buildup or overnight ventilation explain the morning-heavy pattern?
Key points to communicate
- •Please document what findings would confirm this cause versus lower confidence.
- •I want an evidence-first workup with clear follow-up criteria.
- •Please note which competing causes should be checked in parallel if results are inconclusive.
- •Please separate metabolic, sleep, autonomic, and medication overlap before narrowing to one cause.
Tests and measurements to discuss

Carbon monoxide risk review if relevant
