As you have surmised, my 'moniker' of "fog" relates to a persistent mental state induced by years and years of OSA that was initially not diagnosed and later not treated effectively.

There is some question as to whether cpap use can ever restore cognitive deficits. Endocrine set points seem to change with repeated nocturnal hypoxia and sleep fragmentation. Even npap treatment that appears to be immediately and profoundly successful can still leave the patient with a lack of return to proper cognitive functioning.

I would suggest as a first step: carefully examining your sleep (via a VCR and cooperative spouse). If your pressure is at a therepeutic level and you are not defeating cpap by mouthbreathing or mask leaks, then there should be an improvement in the 'fog'. If there is no problem with the cpap and the fog does not lift, then I would explore the sleep profile more. What stages of sleep do you experience? Are you having arousals that a PAT test would reveal but that an EEC in a sleep test would not reveal?

You may not get to a sufficiently satisfactory improvement...but the fog should be noticeably clearing. If it is not...don't give up.
And don't start trusting the quacks.
