Thank you for the name of this disorder and link! I've also had this my whole life, and I knew it was a thing that wasn't terribly rare (based on reading comments from others in the past, here on HN and elsewhere), but I think this is the first time I've seen a name for this condition.

The Wikipedia page seems to really describe my condition, except for the potential overlap with ADHD. For example, the "difficulty following oral instructions". I can read something and retain it forever, but if someone speaks to me, it will often go in one ear and out the other.

I sometimes wonder if this could be a result of being a very introverted child who started reading at around 3 or 4 years old. (Because reading is so awesome, why bother listening to people -- and improving your auditory neurology -- after that?)

I think I've probably just adapted to the condition. It doesn't seem like any sort of problem or disability. But I suspect others around me find it much more annoying than I do. ;)
