Positive vs Negative Symptoms

Definition

Positive and negative symptoms are terms used to describe the two main categories of symptoms associated with schizophrenia and other psychotic disorders. Positive symptoms refer to the presence of abnormal behaviors or experiences, such as hallucinations, delusions, and disorganized thinking, which add to the individual's experience. Negative symptoms, on the other hand, denote the absence or reduction of normal functions or behaviors, such as lack of motivation, emotional flatness, and social withdrawal, reflecting a deficit in the individual's capacity to function normally.
