Nathan has functional neurological disorder (FND), diagnosed in August 2024. According to Daily Mail - Home, Nathan described being diagnosed with FND, which the NHS Inform website explains as a problem with how the brain receives and sends information to the body. He now uses a Zimmer frame indoors and a wheelchair for distances over 30 meters outdoors.
According to Daily Mail - Home, Nathan detailed spending three months in hospitals and a rehab facility relearning to walk and talk, with the wheelchair use marking a significant adjustment. Nathan was the first contestant eliminated from The Hunt: Prey Vs Predator. According to Daily Mail - Home, Nathan emphasized that his flare-up and hospitalization had nothing to do with his participation in the show, stating he felt privileged to have taken part before his life changed.
When I saw it, I thought, 'Oh, this is something to challenge myself and prove that I can still sort of do things.' So my main motivating factor was just to be like, I'm not going to be stopped by my diagnosis.
The exact date when The Hunt: Prey Vs Predator was filmed remains unclear, as does what specific medical treatment or therapy Nathan received during his hospitalization and rehabilitation. It is also unknown whether Nathan had any seizures or health incidents during the filming, as reports mention he 'did end up having a seizure' without specifying details.
I was diagnosed in August of 2024 with functional neurological disorder. And at the time, I was just getting left hand side weakness, and I was having seizures, but I was still working, and day to day living normally, shall we say? So, I think it was just for me to prove that I could still do it, which we fast forward to where we are now, and that's not the case.
I didn't see a neurologist again until my big flare up, which put me in hospital for three months. That happened on June 4 2025, so literally a week or two after filming The Hunt. Which is just crazy. So I feel really privileged that I got the chance to do such an amazing show before my life changed forever.
We'd gone to the spa for my wife's 40th birthday, just having a really relaxing day, and then we went up to the hotel room, I had 17 seizures within an hour, and was blue lighted into Blackpool Victoria, at which point I couldn't speak, couldn't say a word, and I was paralyzed from the hip down on the left hand side.
I spent three months within two hospitals and a rehab facility, relearning to walk and talk, and I now use like a Zimmer frame when I'm in the house to get around. But if we're outdoors or anything over like 30 meters, I have to use a wheelchair, which has been a huge adjustment. It's so crazy. It's so crazy to think this time last year I was running around a Bulgarian forest. Now I'm out of breath wheeling up the street.
