Early diagnosis is considered key for autism, but minority children tend to be diagnosed later than white children. Some new work is beginning to try to uncover whyand to raise awareness of the warning signs so more parents know they can seek help even for a toddler.
The biggest thing I want parents to know is we can do something about it to help your child, says Dr. Rebecca Landa, autism director at Baltimores Kennedy Krieger Institute, who is exploring the barriers that different populations face in getting that help.
Her preliminary research suggests even when diagnosed in toddlerhood, minority youngsters have more severe developmental delays than their white counterparts. She says cultural differences in how parents view developmental milestones, and how they interact with doctors, may play a role.
Consider: Tots tend to point before they talk, but pointing is rude in some cultures and may not be missed by a new parent, Landa says. Or maybe moms worried her son isnt talking yet but the family matriarch, her grandmother, says dont worryCousin Harry spoke late, too, and hes fine. Or maybe the pediatrician dismissed the parents concern, and they were taught not to question doctors.
Its possible to detect autism as early as 14 months of age, and the American Academy of Pediatrics recommends that youngsters be screened for it starting at 18 months. While theres no cure, behavioral and other therapies are thought to work best when started very young.
Yet on average, U.S. children arent diagnosed until theyre about 4 1/2 years old, according to government statistics.
And troubling studies show that white kids may be diagnosed with autism as much as a year and a half earlier than black and other minority children, says University of Pennsylvania autism expert David Mandell, who led much of that work. Socioeconomics can play a role, if minority families have less access to health care or less education.
But Mandell says the full story is more complex. One of his own studies, for example, found that black children with autism were more likely than whites to get the wrong diagnosis during their first visit with a specialist.
At Kennedy Krieger, Landa leads a well-known toddler treatment program and decided to look more closely at those youngsters to begin examining the racial and ethnic disparity. She found something startling: Even when autism was detected early, minority children had more severe symptoms than their white counterparts.
By one measure of language development, the minority patients lagged four months behind the white autistic kids, Landa reported in the Journal of Autism and Developmental Disorders.
