Georgia Carroll, the mum of Cody Carroll, eight, has told of her devastation after her son was diagnosed with a little-known disease dubbed 'childhood dementia'09:40, 19 May 2026A mum has told of her shock at discovering her seemingly healthy toddler was suffering a devastating disease - after doctors noticed he had unusually bushy eyebrows.‌Cody Carroll, now eight, was diagnosed with "childhood dementia" aged just three after struggling from recurring ear infections and hearing loss the year prior. While he was fitted with hearing aids to rectify the issue, his mum, Georgia Nonas, noticed several other unusual symptoms, such as him becoming mute after starting to speak.‌He was subsequently diagnosed with autism, but concern was reignited again when doctors noticed his "coarse features", including unusually thick eyebrows.‌READ MORE: 'I lost my brother to dementia and here's the heartbreaking reality of grief'READ MORE: Dementia care in the UK is 'stuck in a system of delay, denial and neglect', charity saysThe eyebrows, paired with an unusually prominent forehead, led doctors to suspect Sanfilippo syndrome, a devastating rare disease also known as childhood dementia. The syndrome causes severe intellectual disability, and typically leads to death in a child's teenage years.Georgia, 29, Cody's mum and full-time carer, was devastated when, after further testing, he was given a formal diagnosis of the disease.‌Opening up to creatorzine.com, the mum said the diagnosis was "the worst day of my life", adding: "It was the worst day of my life. I felt numb and was very much in denial. Myself, Cody’s dad, Callin, and my mum sat in the room when they confirmed it, and it was silent."“I didn’t process it for a long time. I remember sitting at a family BBQ a few days later and I couldn’t hold a conversation. I was completely zoned out.‌“It was like in the movies when all you hear is ringing in your ears and you can’t hear the noise around you. When it started to hit me, I would act fine all day, and then as soon as I was alone, I would cry until I fell asleep. Every morning I woke up, it hit me all over again.” The news came as a shock to Cody’s loving family, with his ear issues first starting when he was one.Georgia said: “We noticed his hearing wasn’t very good, and he was having recurring ear infections. This is a common tell-tale sign of Sanfilippo syndrome, but at the time, we didn’t even know what that was."‌“He also started to show regression in his development. He said ‘mamma’ and ‘baba’, and then never spoke again.” Cody was diagnosed with autism in August 2020, but his consultant spotted the other signs that indicated he may have Sanfilippo. Children with the inherited disease often have features that become more pronounced over time like a prominent forehead, bushy eyebrows, and a pronounced bottom lip.Meanwhile physical symptoms, which tend to develop between the age of one and four, include speech and developmental delays, sleep disturbances, and recurrent ear, nose and throat infections.Cody was diagnosed with type A, the most severe, with a life expectancy of mid-to-late teenage years. Georgia said: “I can’t remember exactly how it was explained to me at the time – it’s hard to concentrate when you receive news like that – but over time and through countless appointments, I picked up what the diagnosis would mean."‌“Cody’s body is missing an enzyme, which means his body has a lot of waste it can’t process, and this builds up on his spinal cord and brain.“It’s progressive – over time, the damage caused by the waste takes away his ability to communicate, eat, and walk, and it causes brain damage. The doctors told me to take him home and give him all my love.” Since his diagnosis in July 2021, Cody has continued to decline, including his mobility, meaning he is often reliant on a wheelchair, and he can no longer swallow solid foods.‌He also has daily painkillers due to muscular and joint pain, and is prescribed a sleeping aid as the condition severely affects sleep, as well as suffering epilepsy, which is common for children with Sanfilippo syndrome.Georgia said: “Daily life can be hard for Cody – his sleep, communication, mobility, and even eating is affected. As a parent, it’s incredibly difficult to see your child in pain. I’m constantly on edge, wondering when the next seizure is coming. Anticipatory grief is a big part of being a parent to a child with Sanfilippo – you start grieving your child the day you get that diagnosis.‌“It’s a gut punch at random times in the day. I’m watching my child fade away every single day, and it’s enough to break a person.” Georgia has been vocal on social media with sharing Cody’s story, helping to raise awareness, having never heard of Sanfilippo syndrome before her son’s diagnosis.While there is no known cure, she is advocating for early diagnosis to be made as accessible as possible for other parents. She said: “I feel it’s important to share Cody’s story because, before his diagnosis, we had never heard of it."‌“When I went looking for a community online, I saw children who looked just like Cody – I couldn’t believe it. I feel like if someone sees Cody’s story and thinks, ‘Oh, my child has those features’, it can lead to an earlier diagnosis – which is so important so we can get them support and therapies to make their lives more manageable.”Alongside her advocacy work online, Georgia takes every day as it comes with her son – who she describes as “the most loving little boy”.She added: “Everyone who meets him is just amazed by him, and I couldn’t be prouder to be his mama. When Cody was diagnosed we lived in a world with very little hope, however in the coming years, we’re very focused on time. We are waiting for the FDA to approve UX111, a gene therapy in America that could mean a much longer future for Cody."‌“It isn't a 'cure' in the traditional sense, but it is a way to slow down the clock. Our biggest wish is to get him to that treatment so we can hold onto the boy he is today for as long as possible – to keep his smile, his laugh, and his spark from being taken away too soon.“I don’t want birthdays to be a sad day, a reminder of the clock ticking. I’m currently in talks with his MPS team in Manchester to see if this would even be possible, and if we will be eligible. Hope is all we can hang onto at the moment. Cody is the light of my life I want to travel and explore the world with him.Article continues below“We have a trip to Disneyland Paris booked this July – we have to make the most of Cody’s time so I just want to make as many memories as possible!”
