His journey comes after a deeply personal diagnosis, as his mother died at the age of 52 after living with FTD. 

Now, as Mr Adams and his brother Cian face the same diagnosis, he will be undertaking the challenge in memory of 12 Irish relatives who all died from FTD.

Mr Adams explained: “Losing my mum the way I did changed everything. 

Now being diagnosed myself, I had a choice and I chose to do something that shows life doesn’t stop here.

Before his Irish challenge, he took on the London Marathon on Sunday, running the full 26.2 miles carrying a 25kg fridge on his back to raise awareness and capture attention for the cause.

Last night, he flew straight to Belfast to begin his challenge across Ireland, starting in Antrim Castle Gardens.

FTD, which affects people under the age of 65, can have a devastating impact on individuals and families. Through this challenge, Mr Adams said he hopes to raise awareness, spark conversation, and show others facing similar diagnoses that there is still a way forward.

The FTD Brothers have set up a fundraising page in support of the Alzheimer Society of Ireland, and of their non-profit, FTD Brothers Foundation.
