Biological therapies assume that the causes of abnormality are physical, so the treatment should be too. Psychosurgery involves deliberately damaging the brain in an attempt to relieve mental symptons, Electroconvulstive therapy involves triggering seizures with electric currents applied through the brain, and drugs interfer with the brain's natural neurotransmitter chemicals.
Only drugs and ECT are mentioned in the spec, but we spent Thursday's lesson looking at psychosurgery as this is useful for evaluating the approach in general, and for comparison with the other two approaches which we will deal with next week. There is a slide of questions at the end of the psychosurgery part of the presentation - answering these with the help of your textbook will give you plenty of detail for the exam (you don't need all the detail about cingulotomies etc).
