Recent statistics reveal a notable increase in autism diagnoses in the United States, with cases rising by 175% from 2011 to 2022.
Traditionally, autism has been perceived as a condition affecting more males than females. But recent studies indicate a shift in understanding.
Research suggests that many young girls are not receiving timely diagnoses or adequate treatment.
While it’s true that autism spectrum disorder (ASD) is often diagnosed more frequently in boys, the situation changes by the time individuals reach adulthood, where the rates for men and women appear to balance out.
The findings from a study examining over 2.7 million medical records of Swedes indicate that the number of undiagnosed girls is declining, highlighting that they may be diagnosed later in life.
Although boys are diagnosed at higher rates in childhood, this gap narrows significantly by around age 20.
This trend implies that autism might not primarily be a male condition; rather, it suggests a delay in proper diagnosis for girls.
Lead researcher Caroline Fife from Sweden’s Karolinska Institute noted that the sex ratio of autism diagnoses may be less skewed than previously believed, particularly evident in adulthood.
Why this discrepancy exists is still somewhat unclear, though some signs of autism manifest differently in girls compared to boys, especially in early childhood.
For instance, research from Stanford University has shown that girls with autism tend to display fewer repetitive behaviors than their male counterparts.
Expectations based on earlier data might cause parents, caregivers, and even health professionals to overlook the potential for autism in females due to ingrained biases.
There’s increasing evidence that suggests women and girls with autism may feel let down by the existing diagnostic and treatment framework.
Previous research has also uncovered neurological differences, such as thicker areas in the cortex of girls diagnosed with autism, but the root causes of these differences remain largely unknown.
At New York University Langone Health, researchers pointed out that genetic factors, pollution exposure, and access to healthcare likely play roles in autism diagnoses.
Since treatments for autism spectrum disorders can vary widely, early diagnosis is crucial for addressing specific needs effectively.
