What is the most common form of biological therapy?
Drugs
What is the aim of drugs?

What is the main drug used for treatment of OCD and what do they do?
Antidepressants, such as SSRIs (selective serotonin reputable inhibitors) which elevate levels of serotonin and cause the orbital frontal cortex to function at more normal levels. Treatment usually lasts between 12 and 16 weeks
What are the two other drugs that could be used to treat OCD and what do they do?
- Anxiolytics drugs- they are used due to their lowering anxiety properties
- Antipsychotic drugs- they have a dopamine lowering effect
What are three strengths of using the biological approach to treat OCD?
- Drugs reduce obsessive thoughts and compulsive behaviour to such a level that a more normal lifestyle can be achieved
- Drugs are relatively cheap and don’t require a therapist. They are also user friendly as people are used to taking medicine for other illnesses
- Julien reported that although SSRIs do not cause symptoms to full disappear, between 50 and 80% of patients improve allowing them to live a fairly normal life which they wouldn’t be able to do without the treatment
