The symptoms for schizophrenia are normally divided into three major categories. The first category is what is referred to as positive symptoms, followed by negative symptoms and lastly the cognitive symptoms.
These are psychotic behaviors that are not clearly evident in healthy people. Patients with positive schizophrenia symptoms tend to lose touch with their reality and unlike the other broad categories of symptoms of schizophrenia; the positive symptoms will often appear and disappear. During the on again off again periods, the symptoms can be very severe, and sometimes they can be hardly noticeable. The severity of the symptoms is depended on whether one is under treatment. Some of the symptoms falling under this category include hallucinations and delusions.
These are the symptoms that are linked to disruptions from normal behavior and emotions. These symptoms are the hardest to tell as part and parcel of schizophrenia, and most people often mistake them for symptoms of other disorders such as depression. They include inability to start or sustain a scheduled activity, lack of pleasure in day-to-day life, withdrawal from normal activities, someone experiencing what is described as a “flat effect” i.e. not showing any movement signs when talking or assuming a monotonous or dull voice when talking.
The last category of symptoms of schizophrenia is the subtle symptoms which, just like their negative counterparts, can be very difficult to identify as part of schizophrenia. These symptoms are mostly associated with the disorder when other tests are done. They include inability to pay attention or remain focused, poor judgmental skills, inability to digest and use information when one learns.
