In a comprehensive register-based study published in The British Medical Journal (BMJ), researchers at the Karolinska Institute followed 2.7 million people born in Sweden between 1985 and 2020. The results show that 2.8 per cent were diagnosed with autism, and that sex differences in prevalence had largely vanished by young adulthood. This challenges the prevailing view that autism is primarily a condition affecting boys.
