Schizophrenia Positive Symptoms

Positive symptoms in schizophrenia refer to an excess or distortion or normal function. Positive symptoms are the ones most typically associated with schizophrenia or psychosis. These include hallucinations,  which are often auditory (often hearing voices). These symptoms are the ones that generally cause people to lose touch with reality. Positive symptoms of schizophrenia can come and go and may not be noticeable at times (see 10 Early Warning Signs of Schizophrenia).

Schizophrenia positive symptoms include:

Delusions – falsely held beliefs usually due to a distorted perception or experience. Delusions are the most common symptom of schizophrenia.Thought disorder – difficulty organizing and expressing thoughts. This might result in stopping mid-sentence or speaking nonsensically; including the making up of words.Disorganized behavior – unusual and inappropriate behavior. This might be childlike behavior or unpredictable agitation.Movement disorder – agitated or repeated movements. Catatonia (non-moving and non-responsive) is also possible.

Positive symptoms often respond more successfully to antipsychotic treatment.
