Krtin Nithiyanandam is a 15-year-old schoolboy from Epsom, Surrey. He is also the brain behind a path breaking new diagnosis technique that could help in the detection of Alzheimer’s, a neurodegenerative disorder, 10 years before it sets in.

Krtin has developed a ‘trojan horse’ antibody, which can penetrate the brain and attach to neurotoxin proteins, which are present in the very first stages of the disease. The antibodies, which would be injected into the bloodstream, are also attached to fluorescent particles, which can then be picked up on a brain scan.
