Biological approach (ECT)
|Electro Convulsive Therapy||Electric shocks to the non dominant part of the brain at between 70-130 volts for about half a second whilst under anesthetic & muscle relaxant|
|Strengths|| - quicker than anti depressants or counselling|
- reasonable success rate
|Weaknesses|| - ethical abuse|
- terrible side effects before muscle relaxants
- memory loss
- not clear why it works
|Khalilian||18 participants. 3 groups: clozapine alone, ECT alone and a combination. Anaesthetic was used so that no one knew who had had the ECT and who hadn't. Combination therapy was superior to either on their own.|
|Pridmore|| Compared rTMS to ECT. ECT slightly better.|
+ couldn't be any investigator effects as no one knew who had ECT and who had rTMS.
- Only 32 patients.
