Predicting Autism in Infants at 12 Months

A new study has developed an assessment process for behaviors in infants that are strong predictors of autism. The work, by Lonnie Zwaigenbaum and others at the Canadian Autism Intervention Research Network developed the Autism Observation Scale for Infants (AOSI).
The AOSI uses 18 specific risk markers for autism developed from retrospective studies, videotape analyses, case reports and the collective clinical experience of the research team. These markers can be rated reliably within a brief clinical assessment, and the observations made at 12 months can be used to help predict which children are at highest risk of autism.
“What this instrument shows us”, says Dr. Zwaigenbaum, “is that you can pick up on the first signs of autism at a very early age – and maybe starting treatment at this early stage of development will make the difference for these children.”
The text of the study isn’t available but these publications from Canadian Autism Intervention Research Network provide more detail: Specific behaviors seen in infants can predict autism, new research shows; Behavioural manifestations of autism in the first year of life

    what does one do when they discover that not only did their son suffer from dexlexia but now
    appears to have auspergers at an
    adult age of 49 is there anything left for him.

    What can one do when their son
    who was diagnosed with deslexia as
    a child and now appears to have
    aspergers which slipped by. He is 49 years old.

  3. The only thing I recommend is to start working on developing the cerebellum. This area of the brain controls balance and coordination [ ] and it also seems to play an important part in emotional control and balance.
    There are various companies who can help with training such as DDAT [ ] and INPP [ ]. You can also look into music and sound therapies which can also be effective. [ ]

    My 13 month old grandson I suspect may have autism. He crawls walks says dada and mama but but doesn’t always look at you when you call his name. He sometimes seems very connected to what is going on and there are times he seems very far away not responsive. He likes to watch tires on a toy tractor go round and round He likes to look at his thumb sits on the floor bending his upper body so it almost touches the floor and scratch the floor with his finger. Are any of these behaviors symptoms of autism

    I am a mother of 4 and I believe my youngest 15 months, may be autistic, she does not make eye contact ever, rippes out her hair and screams randomly and seems very distressed at times with no sign of why…her tongue also protrudes from her mouth since birth, she drooles frequestly, she cannot get off the 1st stage nipple on a bottle….ect…she has been recieving services such as pt, st, and ot since three months….she does not walk but does crawl and refuses to allow her feet to touch the floor, holding them bent against her bottom when crawling, and also will not give hugs or kisses, or allow her hands to be touched, in fact she holds her arms and leggs very stiff when touched or held….she also does not speak…she has childhood seizures and was born with 14.9 jaundice level left untreated for 3 days prior to her readmittence back into the nicu…she also was born not breathing and was this way for approx..1 min or so….I am terrified I wont be able to care for her properly….
