Theo Mayne, one of the breakout stars of the hit BBC show The Traitors UK, has today announced he is joining The Brain Charity as a new ambassador – and is opening up for the first time about the life-changing stroke his mother suffered in 2019.

The 30-year-old content creator, cheerleading coach, and LGBTQ+ advocate is using his platform to raise awareness around brain health, neurological conditions and stroke recovery – a cause deeply personal to him and his family.

Theo said:

“I’ve never spoken publicly about my mum’s stroke before,”

“It was one of the hardest things our family has faced. But now feels like the right time – because I want to help others who might be going through the same and ensure no one ignores the signs.”

From the spotlight to supporting stroke awareness

In November 2019, Theo’s mum suffered an acute stroke after experiencing sudden dizziness and breathlessness at work. The cause remained unclear until, eventually, she was sent home from work with what she thought was vertigo. Luckily, a concerned friend came by to check on her and decided to take her to the hospital, where doctors diagnosed an acute stroke in progress.

Theo was at work when he received the news from his sister, who was with their mum at the time. He recalls the call with vivid clarity – the shock, fear, and helplessness he felt as their world turned upside down.

The stroke left long-term effects, including fatigue, breathlessness, a limp and memory issues. Everyday activities and family routines have to be carefully planned to her changing needs.

Theo said:

“It’s the little things – her walking slower, forgetting small things – that serve as constant reminders,”

“It still upsets me, and there’s always a fear it could happen again. But my mum has shown incredible strength. Her resilience inspires me every day.”

Finding the right cause: a new role with The Brain Charity

Theo has always wanted to work with a charity, but waited until the right opportunity came along.

“The Brain Charity just felt right – it’s not just about strokes, but every aspect of brain health: neurological conditions, mental wellbeing, grief. It felt just right.”

As an ambassador, Theo hopes to raise awareness about the warning signs of strokes, support carers and families, champion mental health in underrepresented communities, and explore his own mind/brain health through seeking an ADHD diagnosis.

A life of energy, purpose and pride

Theo grew up in Leeds and now lives with his partner and stepson. He started cheerleading at 17 and launched his own cheerleading business at just 21. He now runs his club full-time, coaches young athletes, and is a strong advocate for LGBTQ+ inclusion everywhere.

He first caught the public’s eye on Steph’s Packed Lunch and Blankety Blank, but it was his nine-episode run on season one of The Traitors UK that made him a fan favourite. Known for his honesty and warmth, Theo used his screen time to celebrate queer joy and multicultural visibility.

He said:

“I didn’t go on to win – I went to be seen,” “And I want to keep using that visibility to make change and represent people like me.”

Now, as a public figure, coach, and charity advocate, Theo is focused on creating safe, uplifting spaces for young people – especially those from marginalised and underprivileged backgrounds.

“Whether it’s in a cheer session, on social media or on TV, I want to be someone who uplifts others and spreads awareness. If sharing my story helps even one person feel less alone, then it’s all been worth it.”
