5. Obsessive Behavior
Sometimes people with sensory processing disorder will display other obsessive-seeming behaviors as an associated symptom, although this isn’t a symptom that occurs in all cases of SPD. Sometimes this will involve behaviors that go together with something textile-like they will try to touch something that they find interesting or pleasant and go to great lengths to do it even when it’s completely inappropriate to do it.
In older children and many adults, it can oftentimes be misinterpreted by other people as the person being “rude”, but instead be a sign of an underlying or undiagnosed disorder – especially when appearing with other symptoms on this list.
They also might display obsessive behavior due to another condition that might be related to SPD, including ADHD and the autism spectrum. In many cases, this is a major fact that makes a diagnosis of both SPD and related conditions easier for medical professionals.
