A gene-editing treatment shows long-lasting effects in a mouse model of Angelman syndrome, a genetic condition related to autism.

A tool that relies on video cameras and machine learning can identify mice that have mutations in a top autism gene by their behaviors. It also detects how a widely used autism drug affects their movements.

Mice missing an autism gene groom themselves more than usual and have altered circadian rhythms after nighttime exposure to light.

A new treatment curbs deadly seizures in a mouse model of Dravet syndrome, a severe form of epilepsy.

Autistic people and their families are increasingly experimenting with marijuana to try to ease problems such as insomnia, epilepsy and chronic pain — and traits of autism. But there is little evidence for its safety or effectiveness.

A new method that suppresses gene expression in the embryos of fish and mice may help researchers study autism genes in early development.

Mice missing the autism gene NLGN3 have altered social behaviors and brain responses to the hormone oxytocin, both of which improve after treatment with a drug that helps regulate protein production.

An experimental drug silences a DNA segment and seems to prevent seizures and death in a condition related to autism.

About 6.5 percent of autistic people in the United States also have dyslipidemia, a condition characterized by abnormal lipids levels in the blood.

Doctors and scientists should consider sleep problems an integral part of autism and begin to study them in more rigorous ways.
