15.8.3 Schizophrenia: Early Warning Signs

Early detection and treatment of conditions such as heart disease and cancer have improved survival rates and quality of life for people who suffer from these conditions. A new approach involves identifying people who show minor symptoms of psychosis, such as unusual thought content, paranoia, odd communication, delusions, problems at school or work, and a decline in social functioning—which are coined prodromal symptoms—and following these individuals over time to determine which of them develop a psychotic disorder and which factors best predict such a disorder. A number of factors have been identified that predict a greater likelihood that prodromal individuals will develop a psychotic disorder: genetic risk (a family history of psychosis), recent deterioration in functioning, high levels of unusual thought content, high levels of suspicion or paranoia, poor social functioning, and a history of substance abuse (Fusar-Poli et al., 2013). Further research will enable a more accurate prediction of those at greatest risk for developing schizophrenia, and thus to whom early intervention efforts should be directed.

Forensic Psychology

In August 2013, 17-year-old Cody Metzker-Madsen attacked 5-year-old Dominic Elkins on his foster parents’ property. Believing that he was fighting goblins and that Dominic was the goblin commander, Metzker-Madsen beat Dominic with a brick and then held him face down in a creek. Dr. Alan Goldstein, a clinical and forensic psychologist, testified that Metzker-Madsen believed that the goblins he saw were real and was not aware that it was Dominic at the time. He was found not guilty by reason of insanity and was not held legally responsible for Dominic's death (Nelson, 2014). Cody was also found to be a danger to himself or others. He will be held in a psychiatric facility until he is judged to be no longer dangerous. This does not mean that he "got away with" anything. In fact, according to the American Psychiatric Association, individuals who are found not guilty by reason of insanity are often confined to psychiatric hospitals for as long or longer than they would have spent in prison for a conviction.

Most people with mental illness are not violent. Only 3–5% of violent acts are committed by individuals diagnosed with severe mental illness, whereas individuals with severe mental illnesses are more than ten times as likely to be victims of crime (MentalHealth.gov, 2017). The psychologists who work with individuals such as Metzker-Madsen are part of the subdiscipline of forensic psychology. Forensic psychologists are involved in psychological assessment and treatment of individuals involved with the legal system. They use their knowledge of human behavior and mental illness to assist the judicial and legal system in making decisions in cases involving such issues as personal injury suits, workers' compensation, competency to stand trial, and pleas of not guilty by reason of insanity.
