How many people with autism are also obese?

At 6 months of age, babies who will later develop autism begin to lose some of their social skills and continue to regress until age 3, according to a study published in the Journal of the American Academy of Child & Adolescent Psychiatry.

Two high-profile autism researchers have been accused of fraud.

Scientists have identified distinct blood signatures of cytokines — proteins that control communication between cells of the immune system — in individuals with fragile X syndrome and autism.

Young mouse models of fragile X syndrome show a significant lag in the development of synapses, the connections between neurons, according to a study published in Neuron. The findings suggest that a similar mistiming may be responsible for the sensory problems — such as hypersensitivity to touch and sound — sometimes seen in people with fragile X syndrome.

There are several short periods during development in which our brains are ‘plastic’ — meaning that neuronal connections appear and disappear depending on how much they are used. Researchers may have found a way to reopen those learning windows.

With an openness to collaboration and a healthy dose of daring, Evan Eichler has turned his offbeat interest in repeat DNA sequences into a new understanding of how genomes evolve, expediting the search for genes disrupted in autism.

We know that carrying one specific DNA variant can increase your risk of autism. What if you carry two?

Scientists have created machines to detect distinctive speech patterns in children with autism that go unnoticed by the naked ear.

The ability to recognize faces and interpret facial expressions is programmed partly by genes and inherited separately from other traits, according to three independent studies published this year.
