Small study suggests signs of autism may appear by first birthday

HealthDay (2/17, Dotinga) reported that, according to a paper appearing in the March issue of the Journal of the American Academy of Child & Adolescent Psychiatry, “signs of autism don’t appear in infants before they’re six months old, but do start emerging by the time they reach the age of one year.” University of California-Davis researchers “tracked 50 children until the age of three years, recording the number of times that they communicated — by smiling, babbling, and making eye contact — during exams.” Notably, “by the time the children were one year old, attempts at communication decreased in those who were autistic, but increased in the others.”
