More than 80 years since autism’s first clinical description, researchers have built a wealth of information and scientific consensus around boys on the autism spectrum—but comparatively little is known about autistic girls.
It’s a matter of statistics, says James McPartland, PhD, Harris Professor in Yale Child Study Center and director of the Yale Center for Brain and Mind Health (CBMH). “Around the world, there are three or four boys diagnosed with autism for every girl,” he says. “So, when we do a study, we're learning 75% more about boys than girls.”
Historically, McPartland notes, that has also meant major gaps in diagnosis and care for autistic girls and women.
On Sept. 25, Yale CBMH and the Matthew Hillman Fisher Foundation gathered 22 researchers from across the United States and Europe in New Haven to pinpoint where those gaps exist and identify opportunities for future progress. They were joined by people with autism, caregivers, advocates, and others personally impacted by a condition that often goes undiagnosed or misdiagnosed in girls and women.
