Autistic people have a higher-than-average chance of developing a neurodegenerative condition, according to a few studies. Some scientists are searching for proof — work that could also improve care for older autistic adults.

A short questionnaire created in consultation with autistic people is the first of its kind to accurately gauge suicidal thoughts and behaviors among adults on the spectrum.

Some types of restricted and repetitive behaviors become more prevalent among autistic children and teenagers over time, depending on their age and intellectual ability, whereas others decrease.

Ethan Scott packs his lab with math, physics and computer science experts to decode sensory brain networks in zebrafish models of autism.

Over the past century, scientists have used a variety of animal models to advance their understanding of the developing brain and autism.

In the past two decades, some autism researchers have turned to simple animals, such as roundworms, fruit flies and zebrafish, for their investigations. Others have sought answers from experiments with frogs, birds and even octopuses.

Researchers are increasingly turning to simple animals to learn about autism biology and find leads for new drugs.

Octopuses can solve some of the same problems as people but do so in unusual ways.

A Paris-born child psychiatrist, Fombonne has advanced bold positions on the cause, prevalence and nature of autism during a career spanning four countries.

An autism brain imaging study published seven years ago received an expression of concern last month after its authors failed to uphold a promise to make their raw data freely available.
