Siblings' behaviour affected by autistic child, says study

Children with a sibling who has autism are more likely to develop hyperactivity, a new study has shown.

The research, which is published in the March issue of the journal Focus on Autism and Other Developmental Disabilities, says that while the impact on older siblings was not statistically noteworthy, it could indicate the presence of symptoms associated with broader autism characteristics.

Commenting on the research, Laura Lee McIntyre, a professor and director of the University of Oregon's school psychology program, said: "Children with siblings with autism may be experiencing some sub-clinical symptoms of hyperactivity or attention problems."

"Parents didn't report seeing such things at home. Teachers see these children in a more structured environment. Siblings of children with autism may be at heightened risk for developing problems, potentially over time," she added.

Last week, the British government announced a new adult autism strategy, which aims to help people with the condition find work and integrate into society.
