What causes ADHD (Etiology)?
A single cause has not been conclusively proven (idiopathic). Some possibilities are: Genetic/Hereditary (strongest correlation) Brain damage (head trauma) before, after and during birth (twice as likely to have had labour> 13hrs) Brain damage by toxins (internal bacterial and viral, external fetal alcohol syndrome, metal intoxication, eg. lead) Strongly held belief by some people (including at least one book Feingold’s “Cookbook for Hyperactive children”) that food allergies cause ADD. This has not been proven scientifically.
