The mum of a five-year-old boy with a rare form of dementia has to pay almost £3m for his life saving treatment.

Tate McDaid, from Swansea, was diagnosed with Sanfilippo Syndrome - a form of dementia that just over 100 UK children have - when he was four.

In September, the first gene therapy to treat the condition in children was approved in the US.
