Two brothers who learned they both carry a rare faulty gene linked to dementia are using the devastating news as fuel to run the London Marathon and then the entire length of the UK to raise money for the Alzheimer's Research UK charity.
Jordan Adams, 28, and Cian Adams, 23, from Worcestershire, England, learned they carry the gene that can lead to frontotemporal dementia (FTD). According to the BBC, it's the same disease that killed their mother, Geraldine, when she was 52 years old in 2016.
