Why terminology and assumptions around autism need more careful understanding

A lot of confusion online comes from how people try to categorize autism into “high-functioning” and “profound” without fully understanding what those terms actually mean in real life. In many cases, what gets called high-functioning autism is associated with average to above-average IQ scores, partly because standard IQ tests tend to measure certain types of cognitive and problem-solving skills more effectively. But IQ alone does not define autism, and it doesn’t reflect the full picture of how someone experiences the world or what kind of support they may need. Even when someone is described as high-functioning, that does not mean they are free from challenges. Many still experience difficulties with executive functioning, sensory processing, and communication and may also have co-occurring conditions. Autism is not a single linear scale, and functioning labels often miss the complexity of individual needs. On the other side, profound autism typically involves significantly higher support needs, which may include non-speaking individuals, intellectual disability, and the need for lifelong assistance with daily living. These are not just “more intense versions” of the same experience; they can be fundamentally different lived realities that require a very different level of understanding and care. There are also traits and co-occurring conditions that can appear across the spectrum. For example, alexithymia, which affects emotional awareness and identification, is more common in autistic people. Some individuals may also experience synesthesia. These conditions vary widely and are not universal, but they help show how diverse autism presentations can be. Because of this complexity, it’s important that conversations, especially about profound autism are grounded in accurate understanding rather than assumptions. Misusing terms or relying on stereotypes can unintentionally create confusion or offense, even when that’s not the intention. Taking a little time to understand the differences in terminology and lived experience helps make discussions more respectful and more accurate, especially when talking about individuals with high support needs who are often misunderstood or overlooked.
