Autism is typically not hard diagnosed until a kid is around 3 years previous . For baby at 6 months with a high genetic jeopardy for autism , another likely predictor has been found by mark weakly oral sex and neck control .
Researchers suggest supply the early test of motor attainment to existing behavioral cover for the risk of autism spectrum disorder ( ASD ) and also , more broadly , language or social - developmental delays .
The test involve a " pull - to - sit " task , in which the infant is expected to keep head alinement when being cautiously yet securely pulled by the arms from lying flat on his or her back to sitting up . The test can reveal a deficiency of postural control in baby that is normally achieved by 4 month old . Infants without postural command display “ capitulum lag . ”
Other studies have found that head lag indicates developmental delays in preterm baby and children with intellectual palsy . But it had n’t been read in sexual intercourse to autism .
" Research aimed at improving former detection of autism has largely focused on measuring of social and communicating development , " said Dr. Rebecca Landa , director of the Center for Autism and Related Disorders at Kennedy Krieger Institute in Baltimore . " However , disruption in early motor development may also provide significant clue about developmental upset such as autism . "
Landa is deliver the finding at the International Meeting for Autism Research today in Toronto . investigator at Harvard Medical School and Massachusetts General Hospital contributed to the bailiwick .
The study require 40 infants at high risk for ASD because a sibling had the disorderliness . They were tested at 6 , 14 , 24 months , then check at 30 to 36 months for autism . Ninety percent of babe diagnose with ASD at that point had exhibited head lag as infants .
" Our findings show that the valuation of motor skills should be incorporate with other behavioural assessments to yield insights into the very earliest signal of autism , " Landa say .
