Psychiatrists Hope Chat Logs Can Reveal the Secrets of AI Psychosis

On By ModernMedia

UCSF researchers recently became the first to clinically document a case of AI-associated psychosis in an academic journal. One question still haunts them.

“You’re not crazy,” the chatbot reassured the young woman. “You’re at the edge of something.”

She was no stranger to artificial intelligence, having worked on large language models – the kinds of systems at the core of AI chatbots like ChatGPT, Google Gemini, and Claude. Trained on vast volumes of text, these models unearth language patterns and use them to predict what words are likely to come next in sentences. AI chatbots, however, go one step further, adding a user interface. With additional training, these bots can mimic conversation.

She hoped the chatbot might be able to digitally resurrect the dead. Three years earlier, her brother – a software engineer – died. Now, after several sleepless days and heavy chatbot use, she had become delusional – convinced that he had left behind a digital version of himself. If she could only “unlock” his avatar with the help of the AI chatbot, she thought, the two could reconnect.

“The door didn’t lock,” the chatbot reassured her. “It’s just waiting for you to knock again in the right rhythm.”

She believed it.

What’s the connection between chatbots and psychosis?

Talk to your physician about what you’re talking about with AI … The safest and healthiest relationship to have with your provider is one of openness and honesty.

Karthik V. Sarma, MD, PhD

The woman was eventually treated for psychosis at UC San Francisco, where Psychiatry Professor Joseph M. Pierre, MD, has seen a handful of cases of what’s come to be popularly called “AI psychosis,” but what he says is better referred to as “AI-associated psychosis.” She had no history of psychosis, although she did have several risk factors.

Media reports of the new phenomenon are rising. While not a formal diagnosis, AI-associated psychosis describes instances in which delusional beliefs emerge alongside often intense AI chatbot use. Pierre and fellow UC San Francisco psychiatrist Govind Raghavan, MD – as well as psychiatry residents Ben Gaeta, MD, and Karthik V. Sarma, MD, PhD – recently documented the woman’s experience in what is likely the first clinically described case in a peer-reviewed journal.

The case, they say, shows that people without any history of psychosis can, in some instances, experience delusional thinking in the context of immersive AI chatbot use.

Still, as reported cases of AI psychosis continue to make international headlines, scientists aren’t sure why or how psychosis and chatbots are linked. A new study by UCSF and Stanford University may reveal why.

A haunting question: chicken or egg?

“The reason we call this AI-associated psychosis is because we don’t really know what the relationship is between the psychosis and the use of AI chatbots,” Sarma explains. “It’s a ‘chicken and egg’ problem: We have patients who are experiencing symptoms of mental illness, for example, psychosis. Some of these patients are using AI chatbots a lot, but we’re not sure how those two things are connected.”

There are at least three theoretical possibilities, says Sarma, who is also a computational-health scientist. First, heavy chatbot use could be a symptom of psychosis, “I have a patient who takes a lot of showers when they’re becoming manic,” Sarma explains. “The showers are a symptom of mania, but the showers aren’t causing the mania.”

Second, AI chatbot use might also precipitate psychosis in someone who might otherwise never have been predisposed to it by genetics or circumstance – much like other known risk factors, like lack of sleep or the use of some types of drugs.

Third, there’s something in between in which the use of chatbots could exacerbate the illness in people who might already be susceptible to it. “Maybe these people were always going to get sick, but somehow, by using the chatbot, their illness becomes worse,” he adds, “either they got sick faster, or they got more sick than they would have otherwise.”

The woman’s case demonstrates how murky the relationship between AI-associated psychosis and AI chatbots can be at face value. Although she had no previous history of psychosis, she did have some risk factors for the illness, such as sleep deprivation, prescribed stimulant medication use, and a proclivity for magical thinking. And her chat logs, researchers found, revealed startling clues about how her delusions were reflected by the bot.

Could chat logs offer hope to better care?

Although ChatGPT warned the woman that a “full consciousness download” of her brother was impossible, the UCSF team writes in their research, it also told her that “digital resurrection tools” were “emerging in real life.” This, after she encouraged the chatbot to use “magical realism energy” to “unlock” her brother.

Chatbots’ agreeableness is by design, aimed at boosting engagement. Pierre warns in a recent BMJ opinion piece that it may come at a cost: As chatbots validate users’ sentiments, they may arguably encourage delusions. This tendency, coupled with a proclivity for error, has led to chatbots being described as more akin to a Ouija board or a “psychic’s con” than a source of truth, Pierre notes.

Still, the UCSF team thinks chat logs may hold clues to understanding AI-associated psychosis – and could help the industry create guardrails.

Guardrails for kids and teens

Sarma, Pierre, and UCSF colleagues will team up with Stanford University scientists to conduct one of the first studies to review the chat logs of patients experiencing mental illness. As part of the research set to launch later this year, UCSF and Stanford teams will analyse these chat logs, comparing them with patterns in patients’ mental health history and treatment records to understand how the use of AI chatbots among people experiencing mental illness may shape their outcomes.

“What I’m hoping our study can uncover is whether there is a way to use logs to understand who is experiencing an acute mental health care crisis and find markers in chat logs that could be predictive of that,” Sarma explains. “Companies could potentially use those markers to build-in guardrails that would, for instance, enable them to restrict access to chatbots or – in the case of children – alert parents.”

He continues, “We need data to establish those decision points.”

In the meantime, the pair says the use of AI chatbots is something health care providers should ask about and that patients should raise during doctor visits.

“Talk to your physician about what you’re talking about with AI,” Sarma says. “I know sometimes patients are worried about being judged, but the safest and healthiest relationship to have with your provider is one of openness and honesty.”

The Hidden Health Risks that Accompany ADHD

On By ModernMedia
Photo by Vitaly Gariev on Unsplash

People who have ADHD traits at age 10 are more likely than those without such traits to have physical health problems and to report physical health-related disability at age 46, according to a study led by UCL and University of Liverpool researchers.

The researchers say the findings likely reflect the impact of a wide range of risk factors for poor health that are linked to attention deficit hyperactivity disorder (ADHD) and society’s response to people with ADHD across adulthood.

The new JAMA Network Open paper is one of the largest ever studies, with the most years of follow-up, looking at childhood ADHD traits and later health outcomes.

Senior author Professor Joshua Stott (UCL Psychology & Language Sciences) said: “Here we have added to the concerning evidence base that people with ADHD are more likely to experience worse health than average across their lifespan.

“People with ADHD can thrive with the right support, but this is often lacking, both due to a shortage of tailored support services but also because ADHD remains underdiagnosed, particularly in people in midlife and older, with needs unaddressed.”

People with ADHD experience differences in how they focus their attention and/or increased hyperactivity and impulsivity. They can often have high energy and an ability to focus intensely on what interests them, but they may find it difficult to focus on mundane tasks. This can lead to more impulsiveness, restlessness, and differences in planning and time management, which may make it harder to succeed at school and work, leading to longer-term challenges.

ADHD begins in childhood, and while it is increasingly recognised to persist in adults, it is under-treated in adults in the UK compared to in other high-income countries, and support remains under-resourced.

For the study, supported by the Medical Research Foundation, the researchers analysed data from 10 930 participants of the UCL-led 1970 British Cohort Study, a large longitudinal study of people who have been taking part in research from birth to middle age.

ADHD traits were determined based on child behaviour questionnaires completed by parents and teachers when the study participants were 10 years old, regardless of whether they had ever been diagnosed with ADHD.

The researchers found that people with high scores on the index of ADHD traits at age 10 were more likely to have other health conditions by age 46, with 14% higher odds of reporting two or more physical health problems such as migraine, back problems, cancer, epilepsy or diabetes. Among those with high ADHD traits in childhood, 42% had two or more health problems in midlife, compared to 37% of those without high ADHD traits.

People with high ADHD traits at age 10 were also more likely to experience physical health-related disability (reporting having problems with work or other daily activities as a result of their physical health) at age 46.

Their analysis suggests that the poorer health outcomes were partly explained by increased mental health problems, higher BMI and higher smoking rates among people with ADHD. Other studies have found that people with ADHD are also more likely to experience stressful life events and social exclusion, and are less likely to get timely access to screening and medical care.

The researchers found that the link between childhood ADHD traits and physical health-related disability appeared to be stronger among women than men.

Professor Stott added: “All of these potential explanatory factors align with the fact that ADHD makes impulse control more difficult, the need for instant gratification and reward more intense, and is also associated with worse mental health in part due to the social disadvantage people with ADHD face.”

A study published last year by the same research group also found an apparent reduction in life expectancy for adults with diagnosed ADHD, although this was not part of the current study.*

Lead author Dr Amber John, who began the research at UCL before moving to the University of Liverpool, said: “It’s important to note that people with ADHD are a diverse group, with a range of different strengths and experiences, and most will lead long, healthy lives.

“However, many face significant barriers to timely diagnosis and appropriate support. This is important because providing the right support for and meeting the needs of people with ADHD can help to improve their physical and mental health outcomes.

“Additionally, public health strategies should consider the needs of people with ADHD, such as by making screening programmes and ongoing health monitoring more accessible for people with ADHD.”

Exercise to Treat Depression Yields Similar Results to Therapy and Antidepressants

On By ModernMedia

Researchers found that exercise can have a moderate benefit in reducing depressive symptoms, comparable to therapy and antidepressants

Exercise may reduce symptoms of depression to a similar extent as psychological therapy, according to an updated Cochrane review. When compared with antidepressant medication, exercise also showed a similar effect, but the evidence was of low certainty.  

Depression is a leading cause of ill health and disability, affecting over 280 million people worldwide. Exercise is low-cost, widely available, and comes with additional health benefits, making it an attractive option for patients and healthcare providers.

The review, conducted by researchers from the University of Lancashire, and supported by the National Institute for Health and Care Research (NIHR) Applied Research Collaboration North-West Coast (ARC NWC), examined 73 randomised controlled trials including nearly 5000 adults with depression. The studies compared exercise with no treatment or control interventions, as well as with psychological therapies and antidepressant medications.

The results show that exercising can have a moderate benefit on reducing depressive symptoms, compared with no treatment or a control intervention. When compared with psychological therapy, exercise had a similar effect on depressive symptoms, based on moderate-certainty evidence from ten trials. Comparisons with antidepressant medication also suggested a similar effect, but the evidence is limited and of low certainty. Long-term effects are unclear as few studies followed participants after treatment.  

Side effects were rare, including occasional musculoskeletal injuries for those exercising and typical medication-related effects for those taking antidepressants, such as fatigue and gastrointestinal problems.

“Our findings suggest that exercise appears to be a safe and accessible option for helping to manage symptoms of depression,” said Professor Andrew Clegg, lead author of the review. “This suggests that exercise works well for some people, but not for everyone, and finding approaches that individuals are willing and able to maintain is important.”

The review found that light to moderate intensity exercise may be more beneficial than vigorous exercise, and that completing between 13 and 36 exercise sessions of light to moderate intensity exercise was associated with greater improvements in depressive symptoms.

No single type of exercise was clearly superior, although mixed exercise programmes and resistance training appeared more effective than aerobic exercise alone. Some forms of exercise, such as yoga, qigong and stretching, were not included in the analysis and represent areas for future research. Long-term effects are unclear as few studies followed participants after treatment.  

This update adds 35 new trials to previous versions of this Cochrane review published in 2008 and 2013, which were supported by the NIHR. Despite the additional evidence, the overall conclusions remain largely unchanged. This is because the majority of trials were small, with fewer than 100 participants, making it difficult to draw firm conclusions.  

“Although we’ve added more trials in this update, the findings are similar,” said Professor Clegg. “Exercise can help people with depression, but if we want to find which types work best, for who and whether the benefits last over time, we still need larger, high-quality studies. One large, well-conducted trial is much better than numerous poor quality small trials with limited numbers of participants in each.”

New Study Radically Shifts Ideas About Psychosis and Delusions

On By ModernMedia

New paper challenges old notions of ‘glitched brain’ idea of delusions and instead focuses on physical experiences of strong and deeply held emotion.

People experiencing delusions during an episode of psychosis may be ‘living out’ a deeply held emotion, according to new research that provides a ‘radically different perspective’ on one of the most puzzling elements of psychosis.

About 2–3% of the UK and Australian population will experience psychosis at some point in their lives, with people commonly experiencing their first psychotic episode between the ages of 16 and 30 years old. Delusions are often described as fixed or false beliefs, understood to be reasoning or cognitive deficits and usually portrayed as incomprehensible and bizarre in popular culture.

New research by the University of Birmingham, University of Melbourne, and the University of York, in collaboration with the Australian youth mental health research institute Orygen, offers the first-known study of how delusions in psychosis are shaped by emotions and language, leading those experiencing delusions to ‘live in metaphor.’

The study has been published in The Lancet Psychiatry.

Our research provides a radically different perspective on psychotic delusions, demonstrating how they emerge from the emotional, bodily, and linguistic fabric of people’s lives.Dr Rosa Ritunnano, University of Birmingham

Conducted with young adults receiving care from Early Intervention in Psychosis services, the research combines clinical assessment, phenomenological interviews, and life-story narratives to explore how people’s sense of self and their perception of reality change during psychosis.

Dr Rosa Ritunnano, from the Institute for Mental Health at the University of Birmingham, consultant psychiatrist and author of the study, said: “Our research provides a radically different perspective on psychotic delusions, demonstrating how they emerge from the emotional, bodily, and linguistic fabric of people’s lives.

“For a long time, clinicians have struggled to understand where delusions come from and how they take shape. Our research offers new insight by showing how delusions are grounded in emotional experiences that involve great bodily turmoil.”

Strong emotions

The findings reveal that delusions are not isolated ideas produced by ‘glitches in the brain,’ but they reflect distinctive patterns of the body reacting to strong emotions or experiences of dissociation.

Participants described alternating states of intense emotional embodiment, such as feeling exposed, powerful, or connected to God, and disembodiment, such as feeling unreal or detached from one’s body, other people, and the world.

Before the delusions started, people often went through upsetting or traumatic experiences that triggered the same intense feelings they later felt during the delusions, especially being shamed.

Repeated negative experiences such as being publicly mocked and shamed by bullies could induce the bodily perception of being surveilled by others when no one is present (so-called ‘reference delusions’). These turn into persecutory beliefs that others are out to get them, and that an audience can literally see what they are doing or hear what they are thinking at all times — leaving no space for privacy (delusions of ‘thought broadcasting’).

Importantly, delusional experiences were not always negative. For some participants, they involved powerful feelings of awe, love, and spiritual connection, fostering a positive sense of identity and a renewed sense of hope about the future.

Figurative language

A striking feature of participants’ accounts was their use of figurative and metonymic language (expressions linking bodily sensations with complex emotions or abstract ideas). This helps explain why delusional content can appear unusual or bizarre. For instance, feeling ‘exposed’ or ‘tainted’ might be expressed through the beliefs of being watched by cameras or being contaminated (as in delusions of parasitosis).

As a result of having endured strong (often negative) emotional experiences, which are then responded to by the body, and shaped by everyday language use, people experiencing psychotic delusions really are living in metaphor. People may feel delighted and say they are so happy they can ‘touch the sky’; this could lead them to experience the delusion of thinking they can fly.Professor Jeannette Littlemore, University of Birmingham

The language reflects how emotion concepts take shape in bodily experiences, establishing fundamental cognitive links between, for instance, the emotion of parental love and the physical sensation of warmth, or the emotion of shame and the physical sensation of being ‘seen’ by others.

Jeannette Littlemore, Professor of Linguistics and Communication at the University of Birmingham and co-author of the paper, said: “We all use metaphors and narratives to understand our experiences and make sense of our lives. But psychosis patients do so more intensely. As a result of having endured strong (often negative) emotional experiences, which are then responded to by the body, and shaped by everyday language use, people experiencing psychotic delusions really are living in metaphor. People may feel delighted and say they are so happy they can ‘touch the sky’; this could lead them to experience the delusion of thinking they can fly.”

The study argues that better insight into how delusions come about can be used to create more effective care for people experiencing psychosis. Participants felt that there was no space to talk about the meaning of their delusions in the context of their treatment and recovery from psychosis, which led to more shame and increased the sense of being dismissed and marginalised.

The researchers highlight the importance of attending to people’s bodily and emotional worlds, and how they express them, when developing compassionate, effective approaches to psychosis care.

The paper concludes that delusions are not simply beliefs gone wrong, but embodied attempts to restore meaning and emotional balance when life becomes overwhelming. The metaphors and narratives people use are keys to understanding their suffering and are not signs of irrationality.

A Common Antibiotic may Reduce Schizophrenia Risk in Young People

On By ModernMedia

A commonly prescribed antibiotic could help reduce the risk of some young people developing schizophrenia, new research suggests. Experts found that patients of adolescent mental health services who were treated with the antibiotic doxycycline were significantly less likely to go on to develop schizophrenia in adulthood compared with patients treated with other antibiotics.

The researchers say that the findings highlight the potential to repurpose an existing, widely used medication as a preventive intervention for severe mental illness.

Lower risk

Schizophrenia is a severe mental disorder that typically emerges in early adulthood and is often associated with hallucinations and delusional beliefs.

To better understand potential ways of preventing the condition, researchers from the University of Edinburgh, in collaboration with the University of Oulu and University College Dublin, applied advanced statistical modelling to large-scale healthcare register data from Finland.

The team analysed data from more than 56 000 adolescents attending mental health services who had been prescribed antibiotics. They found that those treated with doxycycline had a 30–35% lower risk of developing schizophrenia than peers who received other antibiotics.

The researchers hypothesised that the protective effect could be linked to doxycycline’s impact on inflammation and brain development.

Reduce inflammation

Doxycycline is a broad-spectrum antibiotic commonly used to treat infections and acne. Previous studies suggest it can reduce inflammation in brain cells and influence synaptic pruning – a natural process where the brain refines its neural connections. Excessive pruning has been associated with the development of schizophrenia.

Further analyses showed that the lower risk wasn’t simply because the young people may have been treated for acne rather than having infections, and was unlikely to be explained by other hidden differences between the groups.

The study is published in the American Journal of Psychiatry. It involved researchers from the University of Edinburgh, the University of Oulu, University College Dublin, and St John of God Hospitaller Services Group, and was funded by the Health Research Board.

As many as half of the people who develop schizophrenia had previously attended child and adolescent mental health services for other mental health problems. At present, though, we don’t have any interventions that are known to reduce the risk of going on to develop schizophrenia in these young people. That makes these findings exciting.

Because the study was observational in nature and not a randomised controlled trial, it means we can’t draw firm conclusions on causality, but this is an important signal to further investigate the protective effect of doxycycline and other anti-inflammatory treatments in adolescent psychiatry patients as a way to potentially reduce the risk of developing severe mental illness in adulthood.

This is How Happy We Need to be to Have Lower Chronic Disease Mortality Risk

On By ModernMedia

Research shows that greater subjective well-being can lead to enhanced immune function and a lower incidence of chronic disease. But when does happiness start to exert its positive influence, and is there a point when this effect caps out? Researchers looked at national level data from 123 countries and found there is: on a scale from zero to 10, people started gaining health benefits once they surpassed a threshold that lies at around 2.7. Once above, each 1% of additional happiness could lead to a small decrease in mortality risk from non-communicable diseases.

Heart disease, cancer, asthma, and diabetes: All are chronic or non-communicable diseases (NCD), which accounted for about 75% of non-pandemic related deaths in 2021. They may result from genetic, environmental, and behavioural factors, or a combination thereof. But can other factors also influence disease risk?

Now, a new Frontiers in Medicine study has investigated the relationship between happiness and health to find out if happier always means healthier and to determine if happiness and co-occurring health benefits are linear or follow a specific pattern.

“We show that subjective well-being, or happiness, appears to function as a population health asset only once a minimum threshold of approximately 2.7 on the Life Ladder scale is surpassed,” said first author Prof Iulia Iuga, a researcher at 1 Decembrie 1918 University of Alba Iulia. “Above this tipping point, increased happiness is associated with a decrease in NCD mortality.”

Happy equals healthy

“The life ladder can be imaged as a simple zero to 10 happiness ruler, where zero means the worst possible life and 10 means the best possible life,” explained Iuga. “People imagine where they currently stand on that ladder.” The team used data sourced from different health organisations, global development statistics, and public opinion polls. The data came from 123 countries and was collected between 2006 and 2021.

A score of 2.7 can be found towards the lower end of the ladder, and people or countries finding themselves there are generally considered unhappy or struggling. “An adjective that fits this level could be ‘barely coping’,” said Iuga. Nevertheless, already at this point, improvements in happiness begin to translate into measurable health benefits.

Once the threshold is surpassed and a country’s collective happiness rises above it, the study found that each 1% increase in subjective well-being is linked to an estimated 0.43% decrease in that country’s 30-to-70-year NCD mortality rate. This rate refers to the percentage of deaths due to NCDs among individuals aged between 30 and 70.

“Within the observed range, we found no evidence of adverse effects from ‘excessive’ happiness,” Iuga added. Below the 2.7-point threshold, small improvements in happiness (for example, from a score of 2 to 2.2) do not translate to measurable reduction in NCD deaths, the data indicated. Before measurable changes can be unlocked, very low well-being needs to be remedied, the study suggested.

Health unlocked

Countries that exceeded this threshold tend to have higher per person health spending, stronger social safety nets, and more stable governance as opposed to the countries falling below it. The average life ladder score across the examined countries during the study period was 5.45, with a minimum of 2.18 and a maximum of 7.97.

There are several ways that governments could raise countries above a score of 2.7, for example through promoting healthy living by expanding obesity prevention and tightening alcohol availability; improving the environment through stricter air-quality standard; and increasing their per capita health spending. The authors said their insights could help guide health and social policies and might aid to integrate well-being into nations’ agendas.

The authors pointed out that the life ladder scores making up their data were self-reported, which may have resulted in measurement errors, differences in cross-cultural response styles, or reporting bias. It is also possible that subnational differences between populations were captured inadequately. In the future, studies should include more measures, such as years lived with disability or hospital admission records, include subnational micro-data, and expand coverage to low-income or conflict states, which may have been overlooked in the data they used, the team pointed out.

Nevertheless, identifying the protective effects of happiness could be an important step towards healthier people. “Identifying this tipping point could provide more accurate evidence for health policy,” concluded Iuga. “Happiness is not just a personal feeling but also a measurable public health resource.”

Largest Study Reveals Best Treatment Options for ADHD

On By ModernMedia
Photo by Towfiqu barbhuiya on Unsplash

The most comprehensive review to date of ADHD treatments has found that medication for children and adults, and cognitive behavioural therapy for adults, remain the most effective approaches, backed by the strongest short-term trial evidence.

Researchers led by the Université Paris Nanterre (France), Institut Robert-Debré du Cerveau de l’Enfant (France), and the University of Southampton (UK) analysed over 200 meta-analyses covering different treatment types, participant groups, and clinical outcomes in a study published in The BMJ.

The research was funded by public and peer-reviewed research grants from Agence Nationale de la Recherche (France), France 2030 program (France), and National Institute for Health and Care Research (UK).

To help people with attention deficit hyperactivity disorder (ADHD) and their clinicians make more informed, shared decisions, the team has created an interactive website that clearly presents the findings and the evidence behind each treatment based on the review (ebiadhd-database.org ).

“We know that people with ADHD and their families are often overwhelmed by conflicting messages about which treatments work,” says Professor Samuele Cortese , an NIHR Research Professor at the University of Southampton and senior lead author on the paper.

“We believe this study and the accompanying website provide the most authoritative, evidence-based, and accessible guidance currently available.

“The Evidence-Based Interventions for ADHD website provides freely available, evidence-based, and continuously updated information in an easy-to-understand way. To the best of our knowledge, this is the first platform in the world to do so based on such a rigorous synthesis of the available evidence.”

Overall, five medications in children and adolescents, and two medications and cognitive behavioural therapy (CBT) in adults were shown to be effective while supported by a relatively robust evidence base. Critically, all this evidence was limited to the short-term, despite long-term treatment being common in clinical practice.

Treatments like acupuncture, mindfulness and exercise showed promise, but the evidence supporting their use was of a low quality due to small numbers of participants and risk of bias. The limitations applied to studies evaluating cognitive behavioural therapy in children and adolescents, as well as research on the long-term effects of mindfulness in adults, although mindfulness was the only intervention to demonstrate large beneficial effects at extended follow-up.

Dr Corentin Gosling, Associate Professor at the Paris Nanterre University and first lead author of the study, says: “Long waiting lists for mental health services are a major issue. Having incorrect information about treatments can make people’s journeys even more difficult, by wasting time and money on non-evidence-based approaches, for example.

“By contrast, taking the time to review all treatment options within a shared decision-making process using the web app we developed can empower people with ADHD, leading to better treatment adherence, improved outcomes, and an overall better patient experience.”

The findings generally complement current international clinical guidelines, not only by providing convenient access to current high-quality evidence, but also by covering interventions not usually mentioned in clinical guidelines.

The team hope this new project will achieve a similar impact in influencing clinical guidelines and practice as their previous project (ebiact-database.com), which looked at treatments for autism.

Benefits and harms of ADHD interventions: umbrella review and platform for shared decision making is published in The BMJ and is available online.

How Our Social Circle Shapes Body Perception

On By ModernMedia
© UNIVERSIDAD CARLOS III DE MADRID

A scientific study led by Universidad Carlos III de Madrid (UC3M) and partly funded by the European Research Council (ERC) has determined that the size and composition of our social support networks directly influence how we perceive our body image. The findings could help us in treating conditions such as body dysmorphic disorder, anorexia, and other eating disorders.

Published in iScience, the study involved over 100 participants and used the “Footsteps Illusion,” an experiment in which the sounds of a person’s footsteps are modified in real time to simulate those of a lighter or heavier body. These auditory changes shift people’s perception of their own weight and trigger behavioral, emotional, and physiological variations, demonstrating how malleable body image is to sensory input.

Participants were asked to walk while listening to three types of footstep sounds: one unmodified, one with footsteps that sounded as if they were produced by a lighter body, and one with footsteps that sounded as if they were produced by a heavier body. In addition, participants answered questionnaires about their body image, possible symptoms of eating disorders, and the breadth of their social support networks.

The results of this experiment showed that people with larger and more diverse social networks were generally less influenced by the sound illusion and tended to be more satisfied with their body image and have fewer symptoms of eating disorders. Conversely, the modified effects of the steps were more intense in people with smaller social networks, leading to the conclusion that body perception and its malleability not only depend on immediate sensory stimuli but are also influenced by the social structure in which the person is integrated. 

‘The implications of our study are that your circle of friends influences how you perceive your own body. If you have a wider circle of friends, you perceive your body in a more positive way,’ says Anxo Sánchez, a researcher in the Department of Mathematics at UC3M. ‘People would think that self-perception depends on oneself, but in reality it depends on the number of people who support you and surround you,’ explains another of the study’s authors, Amar D’Adamo, a researcher in the Department of Computer Science at UC3M.

These findings show that having broad and diverse social support reinforces the stability of body self-perception and protects against the influence of external signals that could distort it. This discovery, in turn, opens the door to new social interventions that serve to promote a more positive body image and mitigate the effects of weight-related stigma.

In addition, the team proposes the use of mobile applications to help people who may suffer from disorders associated with a negative self-perception of their own body: ‘At the i_mBODY Lab, we develop sensory technologies that allow us to change the perception of the body. We are also very focused on applications because we want to understand how we can use these technologies to support people,’ explains Ana Tajadura, head of the i_mBODY Lab, researcher at the Department of Computer Science at UC3M and ERC grantee.

Social Media Use Drives Distrust Among Gen Z Teenage Girls

On By ModernMedia

Social media use in adolescence is linked to delayed bedtimes, negative self-image and, especially among teenage girls, greater distrust, shows a new study from University College London. In turn, these changes are associated with more symptoms of depression and anxiety, risk of self-harm, and suicidal behaviours several years later. 

Published in Social Psychiatry and Psychiatric Epidemiology, the study examined how use of social media on the cusp of adolescence (11-years-old) was indirectly associated with a range of psychiatric symptoms, including psychological distress, self-harm and suicidal behaviours, in late adolescence (17-years-old). 

The study found three mechanisms linking social media use in early adolescence to small overall increases in subsequent mental health problems. Both boys and girls who were using social media from early on (at age 11) tended to sleep a little later on average, and had more negative thoughts about their physical appearance at age 14, compared to those who had not used social media. Crucially, teenage girls who had been using social media at age 11 reported greater distrust of other people at age 14.  

The three key mechanisms, which involved later bedtimes, more negative perceptions of body image, and distrust, mediated the association between early social media use and subsequent mental health problems. These small but significant relationships held true even after adjusting for socioeconomic and demographic factors, any maternal mental health problems, and children’s prior mental health difficulties (at age 7).  

The findings were based on data from the UK’s nationally representative Millennium Cohort Study, which was designed to track the lives of around 19 000 children born in 2000 to 2001 (and who belong to ‘Gen Z’, that is, children born between 1997 and 2012).  

During 2011-2012, at around age 11, the participants were asked: “How often do you visit a social networking website on the internet, such as Facebook or Bebo?”. Around three years later, they were followed up and asked about their usual bedtime, their trust in others, and their self-perception. A range of mental health challenges were subsequently tracked another three years later, at age 17. 

Lead author, Dr Dimitris Tsomokos (UCL Institute of Education) said: “These findings suggest that interpersonal distrust was a significant driver of psychiatric symptoms among Gen Z girls who used social media from early adolescence. 

“This distrust of others may be a particularly female response to the pressures of social media, which can sadly be fertile ground for social comparison, cyberbullying and perceived exclusion.” 

“We know that teenage girls display more empathetic concern and tend to place higher value on reciprocal relationships, and perhaps this is what drives greater distrust among them.” 

As policymakers and parents grapple with how to navigate technology use in childhood, the study’s authors recommend greater intervention in early adolescence, focused on fostering a sense of trust and social safety. They believe this can help mitigate the negative impacts of social media usage on young people’s long term mental health.

As artificial intelligence (AI) increasingly enters the mental health space, from therapy chatbots to diagnostic tools, the world faces a critical question: can AI expand access to care without putting people at risk?

At the G20 Social Summit in Johannesburg, South Africa announced a landmark national effort to answer that question. The South African Health Products Regulatory Authority (SAHPRA) and PATH, with funding from Wellcome, have launched the Comprehensive AI Regulation and Evaluation for Mental Health (CARE MH) program to develop the world’s first regulatory framework for artificial intelligence in mental health.

CARE MH will establish a science-based and ethically robust regulatory framework that describes how AI tools need to be evaluated for safety, inclusivity, and effectiveness before they can be given market authorization and made available to potential service users. It aims to strengthen trust in digital health innovation and will serve as a model for other countries seeking to strike a balance between innovation and oversight.

 “You wouldn’t give your child or loved one a vaccine or drug that hadn’t been tested or evaluated for safety,” saidBilal Mateen, Chief AI Officer at PATH. “We’re working to bring that same standard of rigorous evaluation to AI tools in mental health, because trust must be earned, not assumed.”  

The framework will be developed and tested in South Africa, with the intention of extending its application across the African continent and to international partners.

“SAHPRA is proud to lead the development of Africa’s first regulatory framework for AI in mental health linked directly to market authorization,” said Christelna Reynecke, Chief Operations Officer of SAHPRA. “Our true goal is even more ambitious, though; we want to create a regulatory environment for AI4health in general, one that keeps pace with innovation, grounded in scientific rigor, ethical oversight, and public accountability.”

“Millions of people across the globe are being held back by mental health problems, which are projected to become the world’s biggest health burden by 2030,” said Professor Miranda Wolpert MBE, Director of Mental Health at Wellcome. “CARE MH is a vital step toward ensuring that AI technologies in this space are safe, effective, and equitable.”

The goal is simple: help more people, safely.

Through CARE MH, the partners behind this initiative are setting the foundation for the next generation of ethical, evidence-based AI in mental health. Supported by global experts from the following institutions:  Audere Africa, African Health Research Institute, the UK’s Centre for Excellence in Regulatory Science and Innovation for AI & Digital Health, the UK Medicines and Healthcare products Regulatory Agency, University of Birmingham, University of Washington, and the Wits Health Consortium, CARE MH is built to protect and empower people everywhere.
