Myths

“You hear lots of stories about what can cause ADHD. I’d like to know what’s true and what isn’t.

Is it true that food additives can cause ADHD?”

How many times have you heard well-meaning people try and pinpoint the ‘cause’ of your ADHD? “Not enough discipline at home”. “Too much TV”. “Too many computer games”. “Too many food additives”.

This last myth was started in America when a Professor of Allergy claimed that rates of hyperactivity were increasing in proportion to the number of additives in food. This was championed by the press and the story spread around the world.

Clinical trials to investigate this have not proved conclusive. According to the latest guidelines issued by the National Institute for Health and Clinical Excellence (NICE), elimination of artificial colours and additives is not recommended as a routine intervention for ADHD.

However if, for you, there appears to be a clear link between specific foods or drinks and a particular behaviour pattern, you should keep a food diary and speak to your GP about being referred to a dietician.

Is ADHD real?

Some people believe that, because ADHD symptoms can be found in everyone at one time or another, the disorder doesn’t really exist.

Indeed, doctors have recorded cases of unusually inattentive children for over a hundred years. In 1865, the German physician Heinrich Hoffman wrote a poem ‘Fidgety Philip’ who describes a child who cannot sit still, who wriggles and giggles, swings back and forth on his chair and who is “restless... rude and wild”; he exhibits many of the symptoms we have now come to accept as helping to define ADHD.

Today, researchers are gathering more evidence about the existence of ADHD by studying brain scans. These images suggest there are subtle differences in the brains of those who’ve been diagnosed with the disorder.
