Restricted behaviors in autism represent a genetic link with inattention and hyperactivity in attention deficit hyperactivity disorder, say Tinca Polderman and Henrik Larsson.

A brain hub responsible for higher-order tasks may be overly connected in autism and thinly connected in attention deficit hyperactivity disorder.
CHD8, a gene that regulates the structure of DNA, is the closest thing so far to an ‘autism gene,’ suggests a study published today in Cell. People with mutations in this gene all have the same cluster of symptoms, including autism.
The growing prevalence of autism is no different from that of other neurodevelopmental disorders, finds a study of more than 4.5 million people in four countries.
A Swedish twin study plans to search for the shared genetic and environmental origins of autism and attention deficit hyperactivity disorder, which are often mistaken for each other.
A small study published 3 April in Molecular Autism has found that 98 percent of mothers of children with autism have unusual responses to sensory stimuli, including light, sound and touch.
Children born to women who have low levels of the thyroid hormone have a moderately increased risk of developing autism, according to a large Danish study published 10 March in BJOG: An International Journal of Obstetrics and Gynaecology.
Children born to fathers older than 45 years have a heightened risk of developing a range of conditions, from autism to addiction, according to a large Swedish study published 1 April in JAMA Psychiatry.
Among the younger siblings of children with autism who do not have the disorder themselves, more than one-quarter show developmental delays at their first birthday, according to a study published in April.
An automated system developed for tracking the movements of lab animals can be used to accurately map the activity of children with autism, researchers reported in the February Molecular Autism. When given free rein, the system found, children with autism tend to explore a room’s edges, whereas those with other developmental disorders cling to their parents.
