In schizophrenia, positive symptoms reflect an excess or distortion of normal functions. These active, abnormal symptoms may include:

DELUSIONS– These beliefs are not based in reality and usually involve misinterpretation of perception or experience. They are the most common of schizophrenic symptoms.

HALLUCINATIONS– These usually involve seeing or hearing things that don’t exist, although hallucinations can be in any of the senses. Hearing voices is the most common hallucination among people with schizophrenia.

THOUGHT DISORDER– Difficulty speaking and organizing thoughts may result in stopping speech midsentence or putting together meaningless words, sometimes known as word salad.

DISORGANIZED BEHAVIOUR– This may show in a number of ways, ranging from childlike silliness to unpredictable agitation.
