THE BIOMEDICAL MODEL OF MENTAL ILLNESS • Mental disorders are caused by abnormal biochemical processes in the brain. • Genetic evidence for the biomedical model
SYMPTOMS OF SCHIZOPHRENIA Schizophrenic patients are “split off” or “broken off” from a firm sense of reality. positive symptoms of schizophrenia: delusional thinking, hallucinations (usually auditory), dulled emotions, inappropriate verbal expressions, odd body postures (catatonia).
ANTIPSYCHOTIC DRUG TREATMENT • First-generation antipsychotic drugs: Thorazine, Haldol, Mellaril, Stelazine • Second-generation antipsychotic drugs: Clozaril, Zyprexa, Risperdal • Third-generation antipsychotic drugs: Abilify
SIDE EFFECTS OF ANTIPSYCHOTIC DRUGS • First-generation drugs: Parkinson-like symptoms, tardive dyskinesia • Clozaril: Agranulocytosis in 1-2 percent of patients • Zyprexa and Risperdal: Significant weight gain and development of diabetes, dementia among elderly patients
ANTIPSYCHOTIC DRUGS AND THE BRAIN • In general, antipsychotic drugs are altering the level of stimulation of dopamine-sensitive receptors in the brain. • Subtypes of dopamine-sensitive receptors are differentially affected by various antipsychotic drugs. • Third-generation antipsychotic drugs stabilize (modulate) the level of D2 receptors
Psychiatrists, Children and Drug Industry’s Role By GARDINER HARRIS, BENEDICT CAREY and JANET ROBERTS Published: May 10, 2007 “When Anya Bailey developed an eating disorder after her 12th birthday, her mother took her to a psychiatrist at the University of Minnesota who prescribed a powerful antipsychotic drug called Risperdal.” http://www.nytimes.com/2007/05/10/health/10psyche.html?fta=y
“In 2006, the Food and Drug Administration received reports of at least 29 children dying and at least 165 more suffering serious side effects in which an antipsychotic was listed as the “primary suspect.” That was a substantial jump from 2000, when there were at least 10 deaths and 85 serious side effects among children linked to the drugs. Since reporting of bad drug effects is mostly voluntary, these numbers likely represent a fraction of the toll.” http://www.nytimes.com/2007/05/10/health/10psyche.html?pagewanted=4&fta=y

ANTIDEPRESSANTS AND NEUROTRANSMITTERS • MAO-inhibitors raise functioning levels of norepinephrine and serotonin. • SSRIs raise functioning levels of serotonin. • Third-generation antidepressants raise functioning levels of norepinephrine and serotonin.
DRUGS FOR OTHER TYPES OF MENTAL DISORDERS Mania and bipolar disorders: Lithium, Depakote, Symbyax, Abilify Autism: Risperdal Mild depression: St. John’s wort
