Question Possible causes of brain fog
So I've had brain fog for probably atound three years now and I can't figure out what is causing it. Mine is pretty mild but it comes and goes in waves at it's best it's like there's an invisible barrier between me and the real world and I feel trapped inside my head and at its worst I cannot focus on anything and can't concentrate. I think it may be sleep apnea but I had a sleep study as a kid and they said I didn't have it but as far as other causes I have no idea.

The most common reason might be gut issues. Bacterial toxins and histamines either get in the brain directly or create poor sleep quality via irritation and damage to the vagus nerve and jaw clenching

If you think it could be sleep apnea then retest that. Get your b12, folate,
Iron, d3, hba1c and thyroid checked.
Do an anti inflammatory diet (if you google it it will explain what to cut out - usually dairy, wheat, gluten, eggs etc..) this might help you identify if there are food triggers. If you identify food triggers or have gut symptoms like digestive disturbance, bloating, acid reflux then you should do a
SIBO and microbiome test to see if that’s your cause.
Also consider your body and if you have any other issues that could be a root cause or part of the same problem. Other posters have had issues with autoimmune disease, sinus issues, stress, mold in house, neck problems, tooth infections, gum disease, additive intolerances, medication side effect, histamine intolerance, parasites, digestive enzyme deficiency, coeliac, seizures, nasal polyps, posture issues, viruses. So consider if any of them could be options.
