I have lived with mold-induced brain fog for a long time. I am happy to share what I have learned but want to make sure that I understand your post.

When you say 'moldy place' are you referring to a geographic area (like Florida or Seattle) or your abode?

Do you have other mold-related symptoms (asthma, runny nose, fatigue, heart palpitations, upper and lower GI symptoms, etc.)?

Do your brain fog symptoms vary with mold exposure level?
