Attention Deficit Hyperactivity Disorder (ADHD) is the most commonly diagnosed mental disorder in children. Children with ADHD are hyperactive, unable to control their impulses or have problems staying focused.
ADHD is more commonly seen in boys than girls and can interfere with their daily life by affecting a child’s ability to learn. This can result in a lower self-esteem and problems socialising with others.
While conclusive research has not been done to fully understand the causes of ADHD, child experts believe there are several factors which contribute to the development of the condition.
Research has suggested that ADHD may be hereditary. A child is at higher risk of ADHD if both parents and a sibling have been previously diagnosed with ADHD. However, the role of genetics in ADHD is thought to be complex rather than due to a single faulty gene.
Studies have also shown there are several differences in the brains of ADHD individuals as compared to those who do not have the condition. Some studies have identified that in children with ADHD, certain areas of the brain appear to be smaller, the brain matures at a slower rate, and there may be chemical imbalances in the brain as compared to children who do not have the condition.

More often than not, children with inattentive symptoms are easily overlooked as they may not display disruptive behaviour.
