Autism Spectrum Disorder (ASD) affects 1 in 54 adults, but research on High-Functioning Autism (HFA) in adults is scant due to limited funding and awareness. This dearth of knowledge results in misdiagnosis, underdeveloped support services, and social isolation for adults with HFA. To improve their quality of life, enhanced funding, awareness campaigns, tailored diagnostic tools, and trained service providers are crucial. Collaborating with adults with HFA in research and developing accommodations for aging adults with autism are also essential.
