There's currently an important debate happening about whether the autism spectrum should be divided by severity levels. While some argue this could help tailor support needs better, others worry it could lead to harmful hierarchies that devalue those with higher support needs (PBS, Independent). The discussion was reignited after Health Secretary Kennedy called autism an "epidemic" and focused on environmental causes (NEPM). Many in the autism community caution against splitting the spectrum, as it risks oversimplifying the diverse experiences of autistic individuals (ASAT). The National Institute of Mental Health continues to research autism as a spectrum disorder with varying support needs (NIMH).
