Why are They Called Positive & Negative Symptoms in Schizophrenia

Common Positive Symptoms of Schizophrenia

Hallucinations

Hallucinations are a common positive symptom of schizophrenia. These are deceptive sensory experiences that do not actually exist in the external world. The most prevalent forms are visual hallucinations, meaning seeing things, or auditory hallucinations, meaning hearing voices. In addition, people with the condition might hallucinate a smell, taste, or touch. Psychotic hallucinations happen when you are awake fully with the effects of illicit substances or alcohol. [2]
