This chapter describes schizophrenia and its symptoms in more detail. Schizophrenia is a disease of the brain that affects about one percent of the population, usually occurring between adolescence and young adulthood. Its symptoms vary, but they are by nature disruptive to brain functions, and can include such issues as delusions, slow or confused thinking and movements, hallucinations, and so on. These symptoms can be classified into three categories: positive, negative, and cognitive. Positive symptoms are the presence of sensations, beliefs, and behaviors that would not normally occur. Negative symptoms are characterized by a lack of important abilities, usually those dealing with motivation and socialization. Finally, cognitive symptoms refer to difficulties with concentration and memory.

Keywords:   symptoms, disease of the brain, positive symptoms, negative symptoms, cognitive symptoms, schizophrenia
