We have always taken the approach that we want to get as much information as possible and then decide what to do. We chose to have an audiology exam and when the hearing loss was found, we got our son (who was 6 then) a hearing aid.
If you have a hearing loss, to me, you would want to know and would want to wear a hearing aid. With time, the "CAPD" would likely go away as your brain is retrained and you get better hearing.
Many parents are ashamed to have their kids wear hearing aids- I don't see why, frankly. My son is doing really, really well in school, and we are grateful he has and can wear a hearing aid.
