| EVALUATION of drug therapies | - meta-analysis combining 17 studies comparing SSRIs to placebos. Found that SSRIs significantly reduce symptoms of OCD compared to placebo
- CBT is more time consuming while drug therapy is less expensive and does not require multiple sessions
-drug therapy can have a range of potential side effects like nausea and headache and insomnia |

| what approach is used to explain OCD | biological |
| genetic explanations for OCD | - OCD is inherited, genetic analysis has revealed around 230 seperate candidate genes were found more frequently for people with OCD.
- the SERT gene affects reuptake in serotonin system
- due to large # of candidate genes OCD is considered polygenic |
| neural explations for OCD | - low serotonin levels : low levels of serotonin is likely due to it being removed too quickly from the synapse before it has been transmitted.
- decision making systems : some cases of OCD seems to be associated with impaired decision making. This is linked to abnormal functioning of the frontal lobe of the brain |
| evaluation of genetic explanations | - research support : there is a lot of evidence like twin studies, dizygotic twins have 31% concordance rate and monozygotic twins have 68% concordance rate.
- environmental studies : limitation of genetic model is that it does not take into account the environmental risk factors. this suggests the genetic explanation is a partial explanation for OCD |
| evaluation of neural explanations | - research support : antidepressants that work to increase serotonin levels rare also effective in reducing OCD symptoms
- serotonin and OCD's link may not be due to OCD, many of whom have OCD also have depression so the low serotonin levels could be a symptom of that
- correlational not causational? |
| treating OCD | with drug therapy |
| drug therapies | used to control symptoms of OCD using SSRIs |
| alternatives to SSRIs | SNRI |
| SSRI | Selective Sertonin Rreuptake Inhibitors
- slow down the reuptoke process of serotonin, this increases sertonin level in brain. and decreases anxiety |
| SNRI | increase levels of serotonin and noradrenaline |
