  1. Thinking About Psychology: The Science of Mind and Behavior Charles T. Blair-Broeker Randal M. Ernst

  2. Biomedical Therapies Module 31

  3. Biomedical Therapies • Treatment of psychological disorders that involve changing the brain’s functioning by using prescribed drugs, electroconvulsive therapy, or surgery

  4. Drug Therapies Module 31: Biomedical Therapies

  5. Pre-Drug Therapy • Prior to the discovery of psychological drugs, hospitals had few options with which to treat patients • Most early treatment techniques are today considered archaic and sometimes cruel

  6. Early Treatment of Mental Disorders • Insert “Early Treatment of Mental Disorders” Video #36 from Worth’s Digital Media Archive for Psychology. • Instructions for importing the video file can be found in the ‘Readme’ file on the CD-ROM.

  7. Post-Drug Therapy • With the discovery of effective drug treatments, patients were able to leave the institutions (deinstitutionalization).

  8. Deinstitutionalization • The release of patients from mental hospitals to the community at large • The development of drug therapies led to an 80% decline in the number of hospitalized mental patients from 1950 to 2000. • Many of the former patients became part of the homeless population.

  9. Drug Therapies: Antipsychotic Drugs Module 31: Biomedical Therapies

  10. Antipsychotic Drugs • A category of medications used primarily to treat schizophrenia • Reduces the levels of hallucinations and delusions and distorted thinking • Drugs work by blocking the activity of dopamine

  11. Thorazine • One of the first antipsychotic drugs • Side effects include: dry mouth, blurred vision, constipation, and tardive dyskinesia • Tardive dyskinesia – a permanent condition of muscle tremors

  12. Clozaril and Risperdal • Clozaril: less side effects than thorazine but can cause damage to white blood cells therefore patients need to be tested • Risperdal: no damage to white blood cells • Both Clozaril and Risperdal are very expensive.

  13. Schizophrenia Drug Therapy • Insert “Schizophrenia” Video #34 from Worth’s Digital Media Archive for Psychology. • Instructions for importing the video file can be found in the ‘Readme’ file on the CD-ROM.

  14. Schizophrenia Drug Therapy • Play “Schizophrenia: Pharmacological Treatment” (6:33) Module #28 from The Brain: Teaching Modules (2nd edition).

  15. Drug Therapies: Antianxiety Drugs Module 31: Biomedical Therapies

  16. Antianxiety Drugs • A category of medication used to treat people with anxiety disorders or suffering stress • Work by boosting levels of the neurotransmitter GABA • Can produce dependency • Include: Valium, Librium, and Xanax • Can cause death if mixed with alcohol

  17. Drug Therapies: Antidepressant Drugs Module 31: Biomedical Therapies

  18. Antidepressant Drugs • A category of medications used primarily to treat major depression • Work by influencing levels of serotonin in the brain • Many take about a month before they become fully effective

  19. Selective Serotonin Reuptake Inhibitors • Classification of antidepressants which work by blocking the reuptake of serotonin after it has been released • Includes: Prozac, Zolof, and Paxil

  20. Antidepressants • Play “Mood Disorders: Medication and Talk Therapy” (12:29) Segment #33 from The Mind: Psychology Teaching Modules (2nd edition).

  21. Lithium • Medication used primarily to treat bipolar disorder • Not known how or why lithium works but a large number of bipolar patients report improvement with the drug

  22. Electroconvulsive Therapy Module 31: Biomedical Therapies

  23. Insulin Therapy • Depressed patients are given an overdose of insulin to cause a convulsion. • Difficulties in determining the proper dosage of insulin led to a decline in use of this therapy. • Was replaced by Electroconvulsive Therapy (ECT)

  24. Electroconvulsive Therapy (ECT) • A therapy for major depression in which a brief electrical current is sent through the brain of an anesthetized patient • The current causes a convulsion. • Was preceded by insulin therapy. • Sometimes called “shock therapy.”

  25. ECT Facts • Used when antidepressants fail • Most (80%) patients report improvement • Side effect is memory loss • How and why the process works is unknown

  26. ECT

  27. Electroconvulsive Therapy • Insert “Electroconvulsive Therapy” Video #37 from Worth’s Digital Media Archive for Psychology. • Instructions for importing the video file can be found in the ‘Readme’ file on the CD-ROM. • This segment is also included in The Mind series clip.

  28. ECT • Play “Treating Depression: Electroconvulsive Therapy (ECT)” (5:45) Segment #34 from The Mind: Psychology Teaching Modules (2nd edition). • Parts of this video clip are in the Worth Digital Media Archive CD-ROM.

  29. Psychosurgery Module 31: Biomedical Therapies

  30. Lobotomy • A form of psychosurgery where the nerves connecting the frontal lobes of the brain to the deeper emotional centers are cut • Used to try to calm uncontrollably emotional or violent patients • Regularly done before the advent of antipsychotic drugs • Rarely used today
