It's great you're following autism research! Here's some of what's been happening in 2025.

Researchers have identified four distinct subtypes of autism by analyzing data from over 5,000 children. Each subtype has its own genetic profile and developmental trajectory, which could lead to more personalized care. Also, Yale researchers discovered a molecular difference in autistic brains involving glutamate receptors, which could lead to targeted treatments.

Prevalence has increased to 1 in 31 children, reflecting better awareness and screening. Scientists are also finding biomarkers that can detect autism earlier, like unique patterns in eye-tracking and facial expressions.

I hope this helps!
