Diagnosis

Cut off from clients by the pandemic, clinicians are turning to video conferencing and other technologies to diagnose children with autism.

A new blood test can identify within seven hours whether a person carries the genetic mutation underlying fragile X syndrome.

Individuals with mutations in an autism gene called TRIO may have a range of conditions, including intellectual disability and anomalous head size.

A short, widely used screening survey for autism called the AQ-10 may not be reliable for measuring traits of the condition in the general population.

Autism prevalence in the United States continues to rise, according to a new study of 8-year-old children in 11 states. Boys are 4.3 times as likely as girls are to have autism, a ratio that is consistent with previous estimates.

Autistic infants as young as 6 months display subtle signs of the condition, according to a study of visual attention.

Girls with autism are diagnosed 1.5 years later, on average, than boys with the condition, perhaps because they tend to have stronger verbal skills.
