Certainly they have proven that OSA causes brain damage (e.g.[1]) and causes damage to executive functioning (e.g.[2]).
In reading about the deficits to executive functioning which are caused by OSA I occasionally ran across the concept of emotional awareness. We read emotions in faces, voices, and body language. If we cannot read those I think we become kind of like a bull, with cloudy vision, intermittent hearing, and often a lack of the ability to feel what is touching the fur – going into the china shop – and hardly realizing when we break the very precious but delicate and beautiful things.
Perhaps this explains the social difficulties noticed even early on[3].
One of the reasons I would most like to see improvements in CPAP therapy is that “The most notable neuropsychological improvement with CPAP was in emotional functioning, with a significant improvement in depressive symptoms and quality of life”[4]
Perhaps, with improvements, it could become a way to enable the homeless to become not homeless.
I believe this involves about a third of the homeless population!
