  • 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+)
what causes ocd
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
what causes ocd1
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

biological explanations for ocd
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

plenary
Plenary
  • Complete the ‘Target and Challenge’ worksheet
biological therapies
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

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

evaluating biological therapies
Evaluating Biological therapies
  • For each therapy evaluate its..
  • appropriateness
  • effectiveness
  • What synoptic points are related to this type of therapy?
plenary1
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.
