Rylan's grandmother Rose Walsh was 87-years-old when she sadly passed away last Monday.
Speaking with The Sun, the This Morning presenter said: "I'm absolutely heartbroken, but in a way we lost her months ago."
"The last time I saw Nanny Rose was just over two weeks ago and a part of me wanted that to be the last time I saw her.
"[While we were talking] she suddenly had this moment of clarity. She looked me in the eyes and said 'I love you. Stop worrying.'"
It's been reported that there is now a new blood test that can help fight the cruel disease.

However, Rylan thinks that scientists and the NHS need to go further. The new blood test is revolutionary, but there still needs to be a cure, and he reckons that the NHS can find it.
"We need a cure – surely someone can find a cure," he added.
"I love the NHS but a lot of services do give up on old people.
"This country forgets about old people and it's just not right."

Some 800,000 Brits suffer from Alzheimer’s — and Rylan has added: “I worry I will also develop it. But there’s no use dwelling on this and I wouldn’t want to have the new test done — I wouldn’t want to know.
“What I can’t get past, though, is that we still haven’t come up with a cure. We shouldn’t have to put pressure on the Government to spend more money on this.”
**Do you agree with Rylan Clark - does more need to be done to help the elderly? **
