ADHD in children

Also called Attention deficit hyperactivity disorder in children

ADHD in children shows up as difficulty paying attention, being much more active than other children of the same age, or acting without thinking, in a way that affects home life, friendships and school. It is usually noticed between the ages of 3 and 7, and many children continue to have some symptoms as adults.

What it is

It is more often diagnosed in boys, while girls are more likely to have the inattentive type and to be missed.

Support usually starts with parent training and help at school. Medicine may be offered to children from about age 5 when symptoms remain significant.

Common signs

  • Being easily distracted and not finishing tasks
  • Constant fidgeting, difficulty staying seated
  • Talking excessively, interrupting, difficulty waiting a turn
  • Acting without thinking about danger

How it is usually diagnosed

  • A specialist assessment by a paediatrician or child psychiatrist
  • Information from parents and teachers, usually with questionnaires
  • Checks of growth, heart rate and blood pressure before medicine

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • The assessment report and any school reports
  • Educational support plans
  • Height, weight and blood pressure measurements during treatment
  • A record of medicines and how your child responded

Questions to ask your doctor

  • What help can the school give?
  • What are the pros and cons of medicine for my child?
  • How will growth and sleep be monitored?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Chest pain, fainting or a very fast heartbeat after starting a medicine
