Sensory processing problems can be mistaken for psychosis. Depersonalization is one good example. Acute hearing (hyperacusis) can also be interpreted as auditory hallucinations, especially if the person cannot describe it very well.

Executive dysfunction is another. It is common in both AS and schizophrenia. Often this is seen as "negative symptoms" in the latter. Laziness, tardiness, forgetfulness and disorganization are some issues commonly seen in ED.

I was given the Psychosis NOS label, based on what I have mentioned here. My insight and lack of delusional thought protected my from a schizophrenia diagnosis.

The last time, I went to see a psychiatrist, she noted, that I had blunted affect or the inability to express feelings (adequately and appropriately) verbally and nonverbally.
