They figured out that autism is actually four completely distinct disease clusters with four completely different symptomologies, with some overlap of symptoms in the middle. One of the disease clusters correlates with Fragile X retardation. The idea that we clump together an actual genetic condition that causes retardation with 3 other disorders is ludicrous. Therapists need to understand that many disorders can produce "autism-like" downstream effects, just like many things could cause anxiety or depression. Not understanding the disorders doesn't "help patients". https://www.princeton.edu/news/2025/07/09/major-autism-study-uncovers-biologically-distinct-subtypes-paving-way-precision https://www.princeton.edu/news/2025/07/09/major-autism-study...
