ABR test

Hi
Has anyone been through the ABR test with their toddler?

My 2 year old had been referred for possible ASD and had a routine hearing screen, which to my surprise, failed to respond to any sounds! He's now been referred to have the ABR in a months time. The audiologist also said he had fluid on his eardrums and stiffness.

I just can't understand how he could pass the newborn screen and now this?

I think there is about 5-10% of profoundly deaf children that "pass" the newborn screening, the newborn screening picks up whether there is a response at a key frequency, it doesn't actually test hearing, its like the breast cancer screening, it doesn't pick up every case every time, but its better than no screening at all when a lot of deaf babies were missed.

It could also be possible that a progressive loss, or glue ear is present now, but wasn't, or wasn't significant enough to be picked up at the time of the first screening test.

is he having a sedated ABR?

Also sometimes kids on the spectrum have normal hearing but "fail" at screening tests because they don't show interest in the same way as NT children. My DD isn't that interested in what's going on around her, so if they play a loud sound that usually would cause a child to look towards it to see what's there, she'll ignore it. She's a little deaf anyway, but doesn't respond to her name when called because she's just in her own head space. The more focussed test will tell if he has trouble hearing or trouble responding.

Thanks for the replies.
I do think he has autism as he is very similar to my other son who is ASD. So that would make sense if he was just ignoring the sounds.

He is being given a large dose of melatonin to do the test. Sorry I should of been clearer in my op, he had the ABR as a newborn after they failed to get a clear response from the regular screening. He passed it then but now has been scheduled to have it again. The audiologist said hearing loss can 'slip through' the ABR at newborn stage.

I suppose I'm just desperate to know if my son is deaf confused

How long do you have to wait for your ABR?

yes, audi is right, some can slip though. mine did.

the trouble with unidentified hearing loss in the first 2-3 years, it that it presents similar to autism, things like a dislike of change/transitions, because they don't hear the verbal clues leading up to it. early social skills are missed, things like pointing, eye contact, turn taking, showing an interest in other people/children. also very sensory.
I guess I just want to advise that if a hearing loss is identified, getting that ASD diagnosis may be that little bit harder and take that little bit longer.
