This article was a review, in sorts, of a book called “ADHD does not Exist”. The writer, Dr. Marilyn Wedge was intrigued but later disturbed about what she read in the book. Dr. Saul, who wrote the book, said that there was no biological cause for ADHD. However, the author had treated a child who was having problems with tantrums and remembering things in school with Lithium. Lithium was not approved for the treatment of children and is a very dangerous drug. This article shows that the book may be contradictory.
