I assume you're referring to this:

> And when the brain encounters something it can’t process efficiently, it doesn’t simply adapt. Brain imaging studies cited in the review show it generates stronger neural responses in visual areas, consumes more oxygen, and in some people produces pain, distortion, or worse.

If the studies are of a person's initial exposure to these sorts of conditions, then that doesn't tell us anything about whether people adapt over time (and to be clear I have not read all the studies, but given the limitations listed I'm comfortable assuming they're not incredibly robust until someone tells me otherwise). I suspect the article's use of the word "adapt" is not the same as mine; from the context when they say the brain doesn't adapt they just mean that it shows a response at the time of the particular exposure they're measuring.
