Of all of MTV’s The Challenge seasons, there perhaps has been no harrowing injury as Olivia Kaiser’s. In Season 38’s Ride Or Dies, the 31-year-old and her partner, Horacio Gutierrez Jr., emerged victorious elimination after elimination and defied the odds to make it to the coveted finals. But then an accident with a slingshot left Kaiser with a sliced finger, a broken face, and the disappointment of being medically unable to continue.

A new artificial intelligence (AI) tool may be able to look for early signs of dementia and Alzheimer’s disease, speeding up diagnosis. The technology, which could help doctors assess the early signs of the condition more efficiently, has been developed by researchers at the University of Sheffield. Known as CognoSpeak, the system uses a virtual character displayed on a screen to engage a patient in a conversation. It asks questions to test memory, inspired by those used in outpatient consultations and conducts cognitive tests, such as picture descriptions and verbal fluency tests. This tool could help patients start treatments sooner, reduce waiting times and give people certainty earlier Dr Dan Blackburn, University of Sheffield After that, the tool uses AI and speech technology to analyse language and speech patterns to look for signs of dementia, Alzheimer’s disease and other memory disorders. Researchers behind the technology suggest it could play a key role in reducing the burden on dementia assessment services, once further testing in GP and memory clinics across the UK is complete. The National Audit of Memory Assessment Services in England and Wales, conducted between January and August 2021 by the Royal College of Psychiatrists and supported by Alzheimer’s Society, found that the average waiting time from referral to dementia diagnosis had increased to 17.7 weeks. This was up from 13 weeks in 2019, with waiting times across services nationwide ranging between zero and 104 weeks (two years), compared to three and 34 in 2019. There are currently around 900,000 people in the UK living with dementia, and this is projected to almost double by 2040, according to the Alzheimer’s Society. Dr Dan Blackburn, from the University of Sheffield’s Department of Neuroscience, said: “Waiting for a possible diagnosis of dementia can be a very anxious time for patients and their families. “This tool could help patients start treatments sooner, reduce waiting times and give people certainty earlier. “The CognoSpeak system could transform how dementia and other memory disorders are diagnosed by speeding up assessments. “This would also free up clinicians’ valuable time and mean that those who need specialist care get access to it as quickly as possible.” Also an Honorary Consultant Neurologist at Sheffield Teaching Hospitals NHS Foundation Trust and researcher at NIHR Sheffield BRC, he added: “There is a real clinical need for this kind of technology. “There are long waiting lists for memory clinics across the UK, but there are also inequalities in accessing the memory clinics service. “The CognoSpeak tool can reduce these inequalities and help make the service more efficient.” The CognoSpeak system could transform how dementia and other memory disorders are diagnosed by speeding up assessments Dr Dan Blackburn Professor Heidi Christensen, from the University of Sheffield’s Department of Computer Science, added: “The way a person speaks can tell us a great deal about their cognitive health and emotional wellbeing, and give us a very early indication of any signs of cognitive decline that may not otherwise have been detected. “The system we’ve developed here at Sheffield uses speech technology to automatically extract these signs and the automation means we can provide a consistent, accurate and fast assessment for everyone. “CognoSpeak is advanced, high tech and based on world-leading research in this field. “We have the biggest collection of data for this type of assessment anywhere in the world, which we’re using to advance the technology and improve its accuracy.” The system is being designed in a way that means once it is fully rolled out, a GP could refer a person with memory complaints to use the technology. CognoSpeak would send the test results back to the GP and then they would decide whether to refer the patient to a memory clinic for further assessment. The programme can be accessed through a web browser – meaning patients are able to take the test in the comfort of their home, rather than having to wait for a hospital appointment to take a pen-and-paper-based assessment. Researchers say early trials have shown the technology is as accurate at predicting Alzheimer’s as the current written tests used to assess or screen for cognitive, memory or thinking impairments. According to the team, previous research has demonstrated accuracies of 90% for distinguishing people with Alzheimer’s from people that are cognitively healthy. Developed by Dr Blackburn and Prof Christensen, the system is still in the research phase, but a £1.4 million National Institute for Health and Care Research (NIHR) grant will allow it to be trialled more widely. The researchers are recruiting 700 participants from memory clinics across the UK to help develop the system further. The tool has been developed in collaboration with Therapy Box – a company specialising in speech and language technology – and the National Institute for Health and Care Research (NIHR) Devices for Dignity MedTech Cooperative (D4D).

Intimidating sports culture is putting millions off working out – as many are feeling alienated by the exercise industry. A poll of 2,000 adults who don’t exercise found 68 per cent feel too embarrassed to go to the gym because they don’t fit the mould of the “typical” gym goer. More than three-quarters (78 per cent) don’t find sports adverts motivating and 33 per cent say adverts actually put them off working out. However, 55 per cent would be more likely to exercise if they saw everyday people in sports adverts. And 20 per cent would be more inspired to do something active if there were more realistic expectations set by the industry. A further 29 per cent say sports brands aren’t relatable to them, and a quarter think exercise culture is intimidating. While 49 per cent wish they had more confidence to exercise. The research was commissioned by ASICS as part of its ‘New Personal Best’ campaign, which is calling out performance-obsessed exercise culture in partnership with mental health charity Mind. Gary Raucher, European vice president for the sportswear brand, said: “The sports industry has been telling us for years that the only thing that matters is a faster time, a longer distance, a higher score, and more reps. “Although it’s aimed at motivating people, our research shows it’s having the reverse effect and instead creates an intimidating culture that’s putting people off exercise – something we’re committed to change.” As part of the research, survey respondents were shown a series of marketing images from sportswear and athletic brands and asked to comment on how the pictures made them feel. Just over one in 10 (12 per cent) said the images made them feel ‘inferior’, 13 per cent felt intimidated and for seven per cent, the images even made them feel depressed. It was found 16 per cent typically come across these types of images on social media, with 42 per cent admitting seeing boastful exercise posts makes them feel like a failure – even before they’ve started exercising. Hayley Jarvis, head of physical activity at Mind, added: “For people who don’t exercise, taking that first step can be daunting, especially if they’re also experiencing a mental health problem. “When you add the pressure of performance so often seen in sports marketing or on social media, for some it can feel impossible to get started as they don’t feel like they’re ‘good enough’. “Getting active can play a vital role in helping us stay and live well with mental health problems.” The survey, which was conducted via OnePoll.com, also found 23 per cent of non-exercisers feel too embarrassed to start now, and nearly one in five (18 per cent) worry people would judge them as they are too unfit. Over three quarters (77 per cent) admitted they are aware of the mental health benefits of exercise. But despite 61 per cent saying they have either personally experienced a mental health problem or know someone who has, it is still not motivation enough to get them moving. Mental health activist and TV personality Dr Alex George, who is supporting the ASICS campaign, said: “As someone who is passionate about the benefits of exercise on mental health, it’s upsetting but unsurprising that people feel excluded and alienated by the sports industry. “I too have felt intimidated and insecure after comparing my performance and results to others. “People need to know that regardless of the type of exercise they do, or the times or distances they achieve, any movement benefits mental health and is something that should be celebrated.” The ‘New Personal Best’ campaign features everyday people and is encouraging them to share their own ‘personal best’ images on social media using the hashtag #NewPersonalBest on World Mental Health Day, 10th October. One of which is Tom Durnin, whose inspirational story caught the sports brand’s attention when he finished in last place at the London Marathon 2023. He said: “For me, it was all about crossing that finish line no matter how long it took me. I run purely because it makes me feel good, I don’t worry about my time or being the slowest. “I never thought I’d ever be the face of a sports campaign but I’m honoured to be partnering with ASICS to encourage more people to move for their mental health. “If my story can inspire at least one person to take the first step that’s all I could ask for.” Read More Brits reveal advice they would give their younger selves - including investing in property Girls in UK have much lower confidence than male peers, study finds Average person completes 90 online tasks a day Israel-Hamas conflict: How to talk to teenagers about distressing news stories How to get rid of bedbugs: Signs and symptoms amid threat of UK invasion How to support someone coming out in their 30s and beyond
