A leading neuroscientist has suggested that attention deficit hyperactivity disorder (ADHD) is ''not a real disease''.
Dr Bruce D Perry claimed everyone exhibited a few symptoms of the condition at any given time - and that clinicians are prescribing drugs to treat it far too freely.
Julie Grant, whose 15-year-old son was diagnosed with ADHD six years ago, said her child would be "way out of control" without access to medication.
She told BBC Radio 5 live's Breakfast: "He's damaged my home not being on medication... he's punched holes in my banister, in my furniture and things. As soon as he's on it he just calms right down."
