Signs and symptoms

The presentation of schizophrenia is often highly varied between individuals, making a clear delineation of symptoms difficult. However there are a range of signs and symptoms identified which comprise the schizophrenia diagnosis. These include positive, negative, and disorganised symptoms, as well as cognitive symptoms incorporating both social and neuropsychological dysfunction. Social dysfunction may include emotion processing, lack of illness insight and altered theory of mind, while neuropsychological dysfunction may include problems with attention, executive functioning, learning, decision making and memory. Click on the tabs below to access all the topics, or browse via the drop-down menu on the left..
