So we had our assessment with psychiatrist yesterday.....Good news is that she cant see anything major underlying diagnosis of autism or mental retardation! She says that she wont rule out possible Autism Spectrum Disorders (ASD) but she seems totally convinced that at this moment from what she observed its not applicable.....further.....She said that at you look athis speech delay from between 18-24 months it will put him on a very low IQ, BUT again from what she observes he is a cleverlittle boy with possible average or higher IQ, because when his hands cant get an activity right(because of poor SI)....or his mouth cant say what he wants to he gets VERY frustrated! So she is of opinion that his brain knows very whel what he wants to do or say, but his poor SI and speech delay causes him terrible frustration= indication of high IQ. Conclusion: He has Sensory Integration Disorder (SID) and bad speech delay....I asked her what is the cause of this, she said that in 90% of cases they dont know what causes it.....most propably some neurological delay in those areas....She recommended we need to get an EEG done to rule out any brain abnormalities/immaturities, exct. She also thought that it could maybe help to put him in a school where he can be taught in mother tounge....but had to talk to ST about this......She wanted to give him Risperdal, but I was hesitant! She says she wants his frustrationtolerance to decrease to help with learning to take place....But I just thoughthe is only 4 yrs old and his brain is still developing so much! Might increase ST sessions? Do you have any thoughts on what could be causes of bad speech delays? She said his is to bad to just put it down to language confusion...... So I guess....good news....maybe.....but not really pointing us in further directions!
