Now, the former RTÉ correspondent has taken to X, formerly known as Twitter to deliver a somewhat positive update on his condition.
There, he revealed how he has found a new sense of “freedom” as he was able to get out and about in his new wheelchair for the first time.
Beginning his heartfelt post, Charlie wrote: “I have turned another corner in my life.
“This afternoon I got out, for the first time in my new wheelchair.
“It’s going to give me freedom to continue extending the hand of friendship to people in dark places and helping raise awareness for the elephant in the room for Samaritans,” he added.
Charlie’s comments were then flooded with people’s well wishes with one writing: “You are an inspiration to many and I hope you enjoy your new freedom and mobility.”
“Well done Charlie, you continue to inspire us, thought of you a lot yesterday as I climbed Croagh Patrick with friends, I struggled through some of it and I am in awe of you doing the difficult trek. Keep safe Charlie, keep fighting, and extending the hand of friendship,” penned another.
This comes after Charlie revealed back in August that he could no longer walk unassisted.
In 2022, Charlie famously climbed Croagh Patrick with a group of people, raising a whopping €3.6m for the national suicide prevention charity Pieta House and the Irish Motor Neurone Disease Association.
Since his diagnosis, Charlie has raised millions for several charities around Ireland, including the Irish MND Association, Pieta House, Samaritans and Irish Hospice.
What an inspiration!
