Young Adults Using AI for Health Questions Are More Likely to Screen Positive for Anxiety and Depression A University of Florida survey of nearly 100,000 young adults found that those who used generative AI tools like ChatGPT or Claude for health-related questions had 52% greater odds of screening positive for clinically significant anxiety and 46% greater odds for depression, compared with people who did not use AI this way. This was a cross-sectional survey study, so it cannot say whether AI use causes distress or whether worried young people simply turn to AI for reassurance — the researchers say both directions are possible. Source: News-Medical Depression During Pregnancy Linked to Higher ADHD and Autism Risk in Children Researchers at the University of Glasgow followed more than 167,000 children born in Wales between 2009 and 2016, linking mothers' medical records to children's school records. Children of mothers who experienced depression during pregnancy had higher rates of special educational needs, including autism and ADHD diagnoses, than children of mothers without depression — regardless of antidepressant use, though medication exposure was tied to a small additional increase. The authors caution the extra risk may reflect more severe depression rather than the drugs themselves, and stress that treatment decisions should stay between women and their doctors.

The home-MCT group saw significant reductions in anxiety, depression, and post-traumatic stress symptoms, building on earlier evidence that the same therapy works in group settings — suggesting patients can get real mental-health benefits from an at-home format.
