Biological Treatments of OCD
- As the biological approach explains OCD through the biological makeup of the individual, it also explains the treatments of OCD through biological treatments
- The main biological treatment is the use of drug treatments, which affect the functioning of the brain and neurotransmitter levels
Drug therapy
SSRIs (Selective Serotonin Reuptake Inhibitors)
- The work solely on the neurotransmitter serotonin which is associated with OCD
- They inhibit the re-uptake/ absorption of serotonin, which happens too fast in people with OCD
- By preventing the reabsorption of and breakdown of serotonin, SSRIs effectively increase levels of serotonin in the synapse, which results in the neurotransmitter remaining active in influencing the post-synaptic neuron
- The average time for SSRIs to take effect is 4 months, before they impact on symptoms
Alternative drugs
- SNRI's (Serotonin-Noradrenaline Reuptake Inhibitors), these work in a similar way to SSRIs, but as well as increasing levels of serotonin, they also increase another neurotransmitter called noradrenaline
- Tricyclics, is reserved for those that SSRIs do not work for: It is an older antidepressant and has more severe side effects than SSRIs, so is usually only used on those that other drug therapies have not worked
