A recent study conducted in Sweden challenges the longstanding belief that boys are more likely to be diagnosed with autism than girls. This study, involving 2.7 million children born between 1985 and 2020, found that by the age of 20, women were almost as likely to receive an autism diagnosis as men. This suggests that younger girls may be underdiagnosed, potentially missing out on critical care.
The research, published in the BMJ, spanned a 35-year period and utilized a vast dataset, making it a significant contribution to the understanding of autism diagnosis trends. According to David Mandell, a professor of psychiatry at the University of Pennsylvania, the study is well-executed and provides valuable insights into the prevalence of autism among women.
Gina Rippon, a professor emeritus of cognitive neuroimaging at Aston University, also praised the study for its rigor and the quality of the data collected. She emphasized that the findings may actually underestimate the true prevalence of autism among women, as the study relied on clinical diagnoses.
The study raises questions about the reasons behind the early diagnosis gap between boys and girls. Some experts suggest that systemic biases in diagnosis and the tendency of girls to mask their symptoms may contribute to underdiagnosis in girls. This can have serious consequences, as delayed diagnoses may lead to misdiagnosis with other conditions like anxiety or ADHD.
Overall, the study is seen as a positive step towards addressing the underdiagnosis of autism in girls. By shedding light on the recognition of autistic women, the study may help improve diagnostic practices and ensure that individuals receive the appropriate care and support they need.
