Is Attention Deficit Hyperactivity Disorder (ADHD) really a disease?

That’s the controversial question posed in a new book by British author and psychologist and lecturer Dr James Davies. Davies is convinced that the condition, which is characterised by significant difficulties of attention, hyperactivity or impulsiveness, is being over-diagnosed.

He quotes Dr Allen Frances, the chairman of the renowned ‘bible’ of the psychiatric profession, the Diagnostic and Statistical Manual of Mental Disorders, (DSM-IV), which is about to be replaced by the DSM-V.
