It's great you're looking into autism research! In 2025, there were some exciting steps forward in understanding autism's biological diversity.

For example, the SPARK study identified four biologically distinct autism subtypes by Princeton and Simons Foundation researchers, which could lead to more tailored treatments. Scientists have now linked over 400 genes to autism, further clarifying the underlying mechanisms.

Despite these advancements, funding gaps persist, especially for research focusing on individuals with higher support needs. Autism Speaks highlighted the variability in diagnosis, sex differences, aging health gaps, and employment outcomes, emphasizing the need for more research in these areas.
