A large study from Sweden found that autism diagnosis rates may be equal for males and females by adulthood. The study analyzed national health records of over 2.7 million individuals born between 1985 and 2022.

Autism has traditionally been thought to affect mainly boys. However, a recent study suggests that this might not be entirely true. Researchers from Sweden studied the diagnosis rates of autism in over 2.7 million people born between 1985 and 2022. They found that while males were more likely to be diagnosed with autism during childhood, females showed a strong increase in diagnoses during adolescence. By around age 20, the ratio of males to females diagnosed with autism approached 1:1.

The study also found that the overall rise in autism diagnosis rates over the past 30 years is linked to broader diagnostic definitions and social factors. Until now, experts believed that girls tend to have stronger social and communication skills, which can make autism harder to identify. However, this study suggests that females are often diagnosed later than males.

The researchers emphasized the need to better understand why females receive diagnoses later than males. They also highlighted the importance of improving diagnostic practices to ensure that autistic individuals receive accurate diagnosis and appropriate treatment.

This study's findings have significant implications for our understanding of autism and its diagnosis. It suggests that we may need to rethink our assumptions about who is most likely to be diagnosed with autism and why.
