Diagnosis

A pioneering project is showing how, 17 years since the first draft of the human genome, our genes are giving up their secrets and bringing hope to parents around the world.

Children with autism are more likely to have both sleep problems and constipation than would be expected based on the prevalence of each of those conditions.

A new study suggests that its results could lead to a simple test for autism, but statisticians say the test could not be used to screen for the condition in the general population.

The number of children diagnosed with attention deficit hyperactivity disorder (ADHD) has reached more than 10 percent, a significant increase during the past 20 years, according to a new study.

Many autism researchers express satisfaction with the similarities between the ICD-11 and the DSM-5. But some have raised concerns about ways in which the two diagnostic manuals appear to diverge.

The international manual of conditions now includes a diagnostic code for Angelman syndrome — which may enable scientists to systematically collect information about the syndrome.

More than half of people on the spectrum have four to five other conditions. Which conditions, and how and when they appear, varies from one autistic person to the next.

A new tool can predict a genetic problem called ‘haploinsufficiency’ in which a mutation impairs the function of one copy of a gene.

The California-based company’s phone application for autism diagnosis is not as far along as initial reports suggested.
