My 26 month old girl only has about 60 partial words, mostly monosyllabic. She is in all other respects normal or even advanced for her age. There are no hearing problems. She has had several pop-out words, and seems to have forgotten words, so that in spite of recent acquisitions her total vocabulary size remains constant. She is well able to repeat individual sounds and usually syllables, even repetitive same-syllable nonsense (like papapa or bububu) but refuses to even try real words or even nonsense words that involve too many changes (like matipa). She is clearly trying very hard to express herself with the few words she does have, so autism doesn't seem to be a problem, but we are worried about apraxia particularly since her half brother has motor dyspraxia. A recent speech therapy assessment has been unable to confirm a CAS diagnosis but has not ruled it out. Are there any main markers or symptoms we should be aware of that might help us point towards a diagnosis? What treatment should she be getting now, regardless of an eventual diagnosis? Where are the main centers for help with apraxia and similar disorders? Any help would be very appreciated.
