  2. A severe and chronic psychological disorder characterized by disturbances in thinking, perception, emotions and behavior. • Schizophrenia has Greek roots meaning “split brain”. Schizophrenia

  3. Affects about 1 in 100 people in the U.S. • There are an estimated 2.5 million people diagnosed with schizo. and 1/3 of these people are hospitalized. • Treatment of schizo. Accounts for 75% of the nation’s mental health hospitalization Stats

  4. It is a psychotic disorder- a disorder in which people confuse reality with fantasy, seeing and hearing things that aren’t there (hallucinations and delusions). • Auditory hallucinations (hearing voices) is most common. • Delusions can take different shapes, but most dwell on themes of persecution Symptoms of Schizophrenia

  5. People with schizo. may • Show bizarre/incoherent speech • Illogical thinking • May not know the time of day • May not know what day or year it is • May not know where they are • May not know who they are Symptoms Continued

  6. Thought Disorder- a Breakdown in the logical structure of thinking and speech characterized by loose associations between expressed ideas. • Our thoughts follow a logical sequence (one thought followed by the next) • In schizo. there is a lack of logical connection of thoughts (speech may even become incomprehensible) Symptoms Continued Again

  7. Positive Symptoms- Hallucinations, delusions, bizarre behavior and thought disorder (tend to fade). • Negative Symptoms- Extreme withdrawal or social isolation, apathy and lack of facial expression of emotions (usually are more enduring). Positive and Negative

  11. Genetic Factors • Genetics plays an important role • Adopted children who have biological parents w/ schizo are more likely to develop schizo • What about identical twins? Causes of Schizophrenia

  12. Biochemical Imbalances • Biochemical imbalances in the nerve pathways in the brain that utilize the neurotransmitter dopamine contribute in the development of schizo. • Brains of schizo people have an excess number of dopamine receptors (could also be over sensitive) Causes of Schizophrenia
