G8 leaders are meeting to discuss how to tackle the growing problem of dementia, as the number of cases globally is expected to treble by 2050.
Tom Coppins had been a truck driver and owner of a haulage business for 30 years when he was diagnosed with dementia at the age of 57. There is little available treatment for his condition, and no cure.
