Schizophrenia symptoms can be categorized into three main groups: positive, negative, and disorganized symptoms.                                                                                                                                                               Positive symptoms include hallucinations (seeing or hearing things that aren’t there) and delusions (false, fixed beliefs).                                                                                                                                                                                         Negative symptoms involve a decrease in normal functions, like reduced emotional expression or motivation.                                                                                    Disorganized symptoms include confused thinking and speech, as well as unusual or bizarre behavior.
