Notice how your child gets easily distracted? Or how he has great difficulty concentrating or sitting still? Or how he has trouble making friends at school? These could just be some symptoms of Attention Deficit Hyperactivity Disorder or ADHD, as it is commonly known. Quite often than not, ADHD is easily overlooked by parents who believe their child will outgrow the behaviour. But if the disorder is not recognised and treated, it can affect the child’s self-esteem and personal development.
