Attention Deficit Hyperactivity Disorder (ADHD) is a behavioural disorder which affects up to one in 20 children. It is much more common in boys than girls.

Children with Attention Deficit Hyperactivity Disorder or ADHD have three main problems:

Inattention — difficulty concentrating, forgetting instructions, and moving from one task to the other without completing any.

Impulsivity — talking over the top of others, having a short fuse, and being accident prone (because they do not think carefully before they act).

Overactivity — constant restlessness and fidgeting (although not all children with ADHD are overactive).

These behaviours are usually much more obvious in children with ADHD than in other children their age. Other difficulties can include:clumsiness, planning and organisational problems, inflexibility, poor short-term memory, and difficulty mixing with other children. As a result, children with ADHD usually have problems in learning and may not do well at school.
