What’s the difference between positive and negative symptoms?

    Last Updated: October 25, 2023

    Positive symptoms refer to behaviors or emotions that are added to “normal” thought processes. For example, a person with schizophrenia may have hallucinations where they hear voices or see objects that are not perceivable by others.

    Negative symptoms refer to behaviors or emotions that are subtracted from “normal” thought processes. In this situation, a person with schizophrenia may display a "flat affect" or no emotion at all.
