The woman who says you can spot a psychopath at three years old
'It struck me that when you read prisoners' case histories, there were warning signs that had been there long before they committed their crimes,' she recalls.
Ted Bundy, the notorious American serial killer, was a prime example of this: as a child he liked to dig holes in the ground, laced with spikes, for passers-by to fall in and hurt themselves. He also used to buy mice at the pet shop and pull them apart.
Over the years, there have been even more alarming reports: babies who repeatedly bite their mother's breasts; toddlers who pretend to hug their parents and headbutt them instead.
One of Prof Viding's studies looked at the genetic predisposition to psychopathy in seven-year-old twins, finding that CU traits have a 'strong genetic influence'.
In other words, some children are born more likely to develop personality features that could be red flags.
'No one is born a psychopath'
'You see families where there are concentrations of these traits,' Prof Viding explains. 'No one is born a psychopath and the genes are not a blueprint, but there are people whose genetic makeup means that they are at higher risk than others.'
Our genes and our early social environment shape how the brain processes emotional and social information – and the brains of children at risk of developing psychopathy are different from those of other children, showing little response to emotional stimuli that would normally induce fear. They also tend to have a low resting heart rate, typically associated with stress resilience. Researchers at the University of Cambridge in 2021 found that children whose hearts beat faster at the age of eight were at lower risk of developing adult psychopathy, despite having adverse childhood experiences.
'Children with conduct problems and CU traits, and adults with psychopathy, are poor at feeling what others are feeling, known as emotional empathy,' Prof Viding adds. 'On a conceptual level, they understand it, but that is not the same as feeling it.
'They are better at cognitive empathy, so they can work out what makes someone tick, but they don't care if they make others distressed. This combination makes for a powerful tool for manipulation.'
The latter will chime with most parents – my three-year-old certainly has me wrapped around his little finger – but, if anything, my kids feel too many big emotions, not too few.
'Interventions can work'
It's not all bad news, however, even if a child displays these traits from a young age.
Several studies around adoption show that children at risk of developing worrying behaviours because of their biological family history, if they go on to be adopted by warm, loving parents, are less likely to see those behaviours worsen as they get older. Treatment, Prof Viding says, is effective, such as adapting parenting styles, learning how to help a child regulate their differing reactions, and seeking ongoing professional help in which a therapist works with both child and parents.
'With any behaviour, the more rooted it gets, the more difficult it becomes to intervene. But we know that interventions in adolescents and adults can also work, so the message should not be that if you don't get there in the first five years, it's useless.'
Unfortunately, she adds, getting help to the children who need it is easier said than done, as those who exhibit these tendencies often come from families where their parents have complex issues of their own (such as addiction, mental-health difficulties or problems with the law).
'It is harder to elicit sympathy for children who don't play by the rules and behave in ways that can be unpleasant or downright dangerous,' she says. 'It is an uphill battle to get funding to help these children, even though it would be in society's interest.'
A mother herself, to two teenagers aged 15 and 17, Prof Viding understands only too well the parenting rollercoaster – and how difficult dealing with an unruly child, let alone one showing worryingly abnormal personality traits, can be.
'I get emails on a weekly basis from parents who are concerned and don't know where to turn,' she admits. 'It's heartbreaking.
'At the moment in the UK, the health service is incredibly reluctant to diagnose conduct disorder, so the parents often have to wait until things are so bad they can no longer cope or their child is in trouble with the law.'
But, she insists, no child is beyond reprieve – nor is anyone's little darling 'destined' to become a psychopath. Cue a collective parental sigh of relief.

The ‘small, sustainable changes' that support your long-term health
A new international study, including an expert from the University of Cambridge, has linked regular French fry consumption to a significantly increased risk of developing type 2 diabetes. The research, which analysed nearly four decades of dietary data from over 205,000 US health workers, found that eating French fries three times a week raised the risk by 20 per cent, escalating to 27 per cent for five times a week. In contrast, the study concluded that baked, boiled, or mashed potatoes were not associated with any increased risk of type 2 diabetes. Emma Pike, deputy head of clinical at Diabetes UK, highlighted that while there is no single diet to prevent type 2 diabetes, a healthy, balanced diet, including reducing certain fried foods, plays a vital role in lowering risk. Experts recommend several 'small, sustainable changes', such as opting for whole fruit over juice, homemade sandwiches over pre-packaged ones, and mixed nuts instead of crisps, to support long-term health and reduce diabetes risk.

Lord Hermer in our weight loss ‘deflation club', claims Scottish Secretary
Lord Hermer, the Attorney General, is in a weight-loss group known as the 'deflation club', it has been claimed. The group is said to include Lord Hermer, Steve Reed, the Environment Secretary, and Ian Murray, the Scotland Secretary, who revealed the group's existence in an interview at Edinburgh Fringe on Thursday. Described as the 'fat club', they report their respective weight every Tuesday morning before Cabinet and 'discuss' it on their way into the meeting, Mr Murray revealed. It was allegedly formed around mid-June and had two rules, Mr Murray said: one, that it cannot be spoken about and, two, that people cannot 'use the jab' because it would be 'cheating'. But the outcomes have not been particularly successful, Mr Murray admitted, explaining that, after two months, the 'aggregate score of weight loss is up'. The revelation comes amid speculation in Westminster about which parliamentarians are using the weight-loss drug Ozempic. In July, Wes Streeting, the Health Secretary, revealed that 'half my colleagues' are on weight-loss jabs and that the slimming drugs were 'the talk of the House of Commons'. Last August, Robert Jenrick admitted using it for six weeks in the previous autumn but said he 'didn't particularly enjoy it'. Mr Murray, who has been MP for Edinburgh South since 2010, made the comments in a light-hearted interview with Matt Forde as part of the comedian's Political Party special show at Fringe. Asked who his allies were in Cabinet, Mr Murray hesitated before telling the audience: 'I'm in a slimming club, a Cabinet slimming club called the deflation group. 'It's myself, Steve Reed and the Attorney General. We report our weight every Tuesday morning before Cabinet and we discuss it on the way in. 'We've been doing it for eight weeks and the aggregate score of weight loss is up. '[Steve] Reed blames it on the fact that Crystal Palace won the cup and he's been celebrating since.' Explaining the challenges facing MPs wanting to keep a healthy diet, Mr Murray joked: 'We're sat at the back of a ministerial car so we can't walk anywhere, and really, we're just greedy.' He added: 'I've got a five-year-old and six-month-old daughter and with this job, your body clock is all over the place. Travelling and eating is really bad.' Mr Murray went on to admit that the group's three members were 'better' at monitoring their colleagues' diets than their own. He recalled: 'Richard Hermer, he's a big guy. We had our first Cabinet meeting at Chequers [the Prime Minister's country residence] a few weeks ago and he came in with a plate with a bun on it. 'Steve Reed and I just shamed him throughout the whole Cabinet meeting – and the funny thing was that we had put on weight that week. We're looking after each other's diets but not our own.' Another time, Mr Murray claimed that the Environment Secretary had questioned whether the members' scales were working properly after they had reported a weight gain from the previous week. 'I put new batteries in mine,' Mr Murray said, 'and I was heavier. So I took them back out.' Asked if he has been tempted to use pharmaceutical alternatives to dieting, Mr Murray said: 'There's so many people on jabs in Parliament. You can just tell, because they've gone from a slightly bigger person to a much smaller person in about three weeks.' A series of high-profile politicians have opened up about their decisions to take weight-loss jabs since they became available in the UK in 2019. In June 2023, Boris Johnson revealed he had tried Ozempic but said that after a few weeks of losing weight the injections started to make him feel ill. Nadine Dorries, Mr Johnson's culture secretary, wrote that she too had taken the drug but was happy with her experience using it, despite one incident where she fainted after forgetting to eat for almost 24 hours.

My GP was alarmed by my son's large forehead – it was a symptom of killer that I'd never noticed
CONOR O'Rourke was just nine months old when doctors noticed his "pronounced forehead" during an unrelated appointment. His mum, Lucy O'Rourke, 36, had taken her three-year-old to a consultant about a problem with his belly button. 6 But instead of leaving with reassurance, she was told something far more worrying, her little boy's head looked "quite" large. The doctor said Lucy her son had "a pronounced forehead" and "very visible veins on his forehead, and his temples, around his eyes." These would all turn out to be the first signs of a rare and deadly brain defect called galen malformation (VOGM), that could have killed him within years. It happens when veins and arteries in the brain connect abnormally, flooding it with blood and putting him at risk of heart failure and brain damage. The condition, which can be fatal, affects roughly 10 to 12 babies in the UK every year. 'I genuinely felt like I was living in a nightmare," Lucy, from Bolton, said. "I felt like there was going to be a point where somebody was going to phone me and say, 'sorry, we've mixed up the scans, this isn't your child, we've got it wrong'. 'We just cried and sat in silence for hours. We just didn't know what to do with ourselves.' The treatment for VOGM involves inserting a small, flexible tube called a catheter into the arteries, usually from the groin. Medics use X-ray imaging to guide the tube through the body and into place, and then inject a glue-like substance to block off the artery. In some cases, the same procedure can be performed by inserting the catheter into the veins. How to check your pulse, for risk of stroke Doctors at Alder Hey Children's Hospital in Liverpool carried out three of these procedures on Connor in 2023. But each time, the abnormal connections kept finding another route. By the end of the year, things had taken a frightening turn. Conor's jugular veins, the major vessels in the neck, had blocked completely, forcing blood to drain into his brain stem and spinal cord. He even suffered a small stroke after his third operation in November 2023. Around a year later, and after physiotherapy, the toddler's family were told he was not in a position for more operations and they would scan him in 12 months' time. 6 6 6 'In early December, I started to notice that physically he was struggling," Lucy said, "and he was limping quite a bit on his left leg.' By this point, Conor was essentially 'untreatable", his paediatric neurosurgeon Conor Mallucci said, and had 'run out of all his options'. It was causing swelling and damage to the brain stem and spinal cord, leading him to deteriorate. Mr Mallucci: 'It's a fight against time… you're left with an untreatable malformation that's still supplying abnormal blood to the veins.' With no other options left, the team came up with a high-risk, never-before-attempted procedure in children - open brain surgery to access the blocked veins directly. Alder Hey is one of only two centres in the UK equipped to carry out this procedure on children. The hospital has a state-of-the-art theatre with advanced imaging machinery, giving specialists real-time X-ray pictures of blood vessels during operations and allowing them to combine endovascular and open surgery. The technique has never been performed at another hospital. Mr Mallucci said: 'Exposing these veins that were blocked at the jugular level is high risk. You lose blood. It's a big operation, and to put a needle directly into one of those is a little bit hair raising.' 'Woke up from surgery asking for chips' Lucy had to sign off on the surgery, knowing the dangers but also knowing without it, her little boy's condition would only get worse. Doctors warned Conor would be wiped out for days and could be in hospital for up to six weeks. Instead, to everyone's amazement, he woke up soon after surgery asking for chips. Lucy laughed: 'I obviously went into mum mode and said 'can we get some chips in here please?'' Just 10 days later, the family were home and Conor was already showing signs of a remarkable recovery. Now aged three, Conor recovered well and is now considered "99 per cent cured" by Mr Mallucci. He has left nursery and will be attending pre-school in September. "He's not only recovered well, everything that he had going bad was reversed," Mr Mallucci said. "He's become a different child, really, it's like he's suddenly been released.' "Conor is now '99 per cent cured' and will only need yearly scans, with a possible check-up angiogram in a few years. Lucy said: 'No surgery now, unless we get broken arms or legs, but with something like that, we're kind of like 'bring it on'. "As long as it's not more brain surgery, then we'll probably be able to cope with that.' The Alder Hey team have now performed the new technique on two children, including Conor, and have a third case planned. 6 When is a big forehead a sign of something seirous? A prominent forehead in babies, known as frontal bossing, is typically harmless. But in rare cases, it can be a red flag for underlying conditions. It can be linked to genetic disorders, bone or hormone problems, or issues with brain development. Possible causes include: Craniosynostosis - when skull bones fuse too early, affecting head shape. Metabolic disorders - such as rickets or certain storage diseases Genetic syndromes - like Apert, Crouzon or Pfeiffer syndrome Growth hormone excess - which can cause enlarged facial features Doctors may order scans or blood tests if the forehead looks unusually pronounced or is paired with other symptoms, like delayed development, unusual facial features, or health issues. Most cases are nothing to fear, but if you're worried, get your child checked. Source: Healthline
