Scientists study how babies develop ADHD

Scientists at a laboratory in central London are carrying out tests to try to discover how and why some people develop Attention Deficit Hyperactivity Disorder (ADHD).

The Birbeck Babylab studies how babies learn and has already made progress in understanding how autism develops in young children.

BBC London's Jean Mackenzie spoke to Dr Emily Jones, the lead researcher at the Birkbeck Babylab, and mothers Fiona Mackay and Sheryne Shillingford-Reed.
