Declan McMullan suffered a cardiac arrest aged 19 and spent over a year in hospital before returning home to be diagnosed with locked-in syndrome as a result of the brain damaged he sustained.
He cannot eat, speak or see and is confined to a wheelchair. But he can communicate with his eyes, retains full understanding of what is going on, and can hear.
That's where his brother Mark comes in. In a video destined to go viral, Ulster University student Mark sings Bring Him Home, from Les Miserables, to Declan in their local in County Down, and it's very moving.
Declan has an amazing sense of humour and has shown immense courage and strength throughout. Our amazing son has a long journey ahead, but he will travel that road with the love and support of his family, friends and the wider community.
As his family, we take one day at a time in the hope that he will continue to improve. We are eternally grateful to everyone who has helped him along the way, we will never forget your kindness.
