Schizophrenia

Basic Characteristics

  • Description

Schizophrenia is a mental illness affecting approximately 1% of the population worldwide that is marked by the abnormal perception and expression of reality. The illness typically manifests itself in young adulthood in the form of auditory hallucinations, paranoid or bizarre delusions, and disorganized speech and thinking. Schizophrenia has been known to negatively affect social interactions, vocational and instrumental fucntioning, self care, and recreation. The specific symptoms of schizophrenia may fall into three general categories: postive symptoms, negative symptoms, and cognitive symptoms.Positive symptoms include abnormal thoughts or perceptions such as hallucinations and dellusions as well as disorders of movement. Negative symptoms are typically a lack of speech, emotion, and pleasure in everyday life which are sometimes confused with depression. Cognitive symptoms are deficits in attention, memory, and executive functioning. To date, there are five varieties of schizophrenia comprised of specif combinations of symptoms as determined by the DSM IV: disorganized, catatonic, residual, paranoid, and undifferentiated. Treatment for Schizophrenia is centered around the elimination of symptoms since the specific causes of the mental illness are still unknown. A variety of antipsychotic medications greatly improve the lives of people suffering with the illness although most will struggle with the disorder their entire life.

  • History

Schizophrenia was first identified as a mental illness by Emile Kraeplin in the 1800s. He used the term "dementia praecox" to label people suffering with what we now consider symptoms of schizophrenia. Eugen Blueler coined the label schizophrenia in 1911 beacause found the term "dementia praecox" misleading as the disease did not always occur late in life and did not always lead to mental deterioration. The word "schizophrenia" is Greek in origin, schiz (split) and phrene (mind), meaning split mind as to describe the disagreeing thoughts of those with the disorder.
