DAVID MARK: A new study indicates that the number of autism cases in Australia is increasing among younger children.
Researchers have found that 1.5 per cent of all 10 and 11 year olds have an autism spectrum condition, compared to 2.5 per cent of four and five year olds.
What's not clear is whether the condition is becoming more prevalent, or if it's simply being diagnosed more effectively.
Whatever the cause, experts say Australian schools need to prepare for an increase of autistic students.
