Presentation Transcript

  1. Biological Explanations and Treatments for OCD • BATs • Outline (D/E) and evaluate (C+)the Biological Approach to OCD • Outline biological therapies for OCD (D) • Evaluate the appropriateness and effectiveness of Biological therapies for OCD • (B+)

  2. What causes OCD? • Researchers are split over the cause of OCD • One one hand it is thought to be a Psychological disorder • On the other hand some think it may be the result of abnormalities in the brain

  3. What causes OCD? • At AS ,in the stress and Abnormality topics, you learned that anxiety and fear are natural and adaptive responses (i.e the behaviour had an advantage for survival) • This suggests anxiety and fear have a Biological basis • We might then expect that abnormal fears and anxieties are biologically based http://www.youtube.com/watch?v=ToSNC8levLg&feature=related

  4. Biological Explanations for OCD • In pairs research and make notes or do a presentation about either genetic factors or the Evolutionary approach to OCD • You will then teach the other group • Finish off by doing a summary sheet p206-207 and OCD workbook

  5. Plenary • Complete the ‘Target and Challenge’ worksheet

  6. Biological Therapies • The main biological therapies for OCD are chemotherapy (drugs) and psychosurgery • They are usually used in conjunction with Psychological therapies because they reduce anxiety levels to enable the patient to engage in Psychotherapy • The American Psychiatric Association in 2007 recommended that drugs should only be used in severe cases or in conjunction with psychotherapy

  7. Biological Therpaies • Psychosurgery is a controversial therapy for OCD - see the case study of Mary Lou Zimmerman on p 211 • A fairly recent treatment is less invasive - Transcranial Magnetic Stimulation • In pairs find out about either Chemotherapy or Psychosurgery http://www.youtube.com/watch?v=XJtNPqCj-iA tms http://www.youtube.com/watch?v=hMJJ3DpzXdk&feature=related TMS http://www.youtube.com/watch?v=a1xdB1jNBu8&feature=related deep brain and parkinsons http://www.youtube.com/watch?v=izKL1mVXF7c&feature=related deep brain anim

  8. Evaluating Biological therapies • For each therapy evaluate its.. • appropriateness • effectiveness • What synoptic points are related to this type of therapy?

  9. Plenary • Create a leaflet to inform OCD patients of possible Biological therapies. • or do the Biological Breakdown worksheet to help you write an essay about Biological explanations for OCD - see p 207 for a question.
