Attention Deficit Hyperactivity Disorder (ADHD)

What is Attention Deficit Hyperactivity Disorder (ADHD)?
ADHD is a condition characterised by excessively inattentive, hyperactive (unusually active or over-active) and impulsive behaviour in some children. This behaviour is generally more frequent and intense than in other children the same age.

There are three types of ADHD:

  • Inattention only: children with this type tend to have difficulty concentrating, remembering instructions, paying attention and finishing tasks.
  • Hyperactivity and impulsivity: children with this type tend to be fidgety and always on the go. They appear to act without thinking.
  • Combined type: children with this type show signs of inattention, hyperactivity and impulsivity.

The difference between ADD and ADHD: In the past, the term ‘ADD’ was used to describe the condition we now call ADHD, but without the hyperactivity. ‘ADHD’ is now the generic term used for all three types of the disorder.

ADHD is not just bad behaviour. Parents of children with ADHD will tell you that the discipline strategies they use with their children with ADHD just don’t seem to be effective. Children with ADHD need limits on their behaviour, as well as consistency in the way they are parented and disciplined. But ADHD is not the result of a lack of limits or inconsistent parenting.

Causes of ADHD
Increasingly, genetics is being recognised as at least a partial cause of ADHD. In other words, the brain formation and functioning of children with ADHD is partly determined by their genes.

This means that ADHD is often passed down in families. For example, the risk of an ADHD diagnosis is 6–8 times higher for children with a parent or sibling with ADHD, than for children without this genetic history.

There is no evidence that food intolerances cause children to develop ADHD symptoms.

For a small number of children with ADHD, some artificial food colourings might make the symptoms worse. These colourings include:

  • tartrazine (lemon yellow) (102)
  • quinoline yellow (104)
  • sunset yellow FCD (110)
  • carmoisine (red) (122)
  • ponceau 4R (red) (124)
  • allura red AC (129).

ADHD indicators
Most young children are occasionally inattentive, hyperactive or impulsive. This can make it difficult to diagnose ADHD in children younger than five.

If you’re concerned about your child’s behaviour, though, it’s always a good idea to seek some professional advice. In particular, consider seeing a health professional if your child frequently does several of the following:

  • acts before thinking and doesn’t consider the consequences
  • makes ‘careless’ mistakes in homework
  • jumps from one activity to another
  • isn’t able to get organised
  • is forgetful, particularly when given a series of instructions to complete a task
  • interrupts other people’s conversations
  • acts restlessly – that is, can’t sit still, fidgets, squirms, climbs on things, and doesn’t sleep well
  • can’t stay focused, or is easily distracted
  • day-dreams
  • doesn’t finish homework or chores around the house
  • has trouble listening.

As children with ADHD get older, their behaviour does tend to tone down. So you might not see these indicators as often, or the indicators might be less severe.
