Youngest children in school are more likely to be diagnosed with ADHD, new research reveals.
Greater immaturity compared to their fellow classmates may prompt youngsters to receive the behavioural condition diagnosis, a study found.
Younger girls in a year group are 31 per cent more likely to receive a diagnosis, while such boys are 26 per cent more likely to be told they have attention deficit hyperactivity disorder (ADHD), the research adds.
