ADHD: 'My son was suicidal at eight years old'

There has been a 50% rise in the use of drugs for attention deficit hyperactivity disorder (ADHD) in six years.

Prescriptions for methylphenidate drugs, including Ritalin, rose from 420,000 in 2007 to 657,000 last year, the Care Quality Commission said.

The watchdog warned health workers to "carefully monitor" their use as they have the potential to be "abused".

Diana Foster says her son, who has ADHD, was suicidal at eight years old and that prescribed medication certainly helped him.
