Treating OCD: Biological Approach (Drug Therapy)

HideShow resource information

Drug Therapy

- Drug therapy is used to increase or decrease levels of neurotransmitters in the brain or to increase/decrease their activity.

-Drugs can be used alongside other types of therapy, for example cognitive behaviour therapy (CBT). The drugs help to reduce a patient's emotional symptoms which means they might engage more effetively with the CBT. Some people respond better with CBT alone, so it isn't for everybody.

SSRIs

- Is a type of antidepressant called selective seretonin reuptake inhibitor. Trade names include: Prozac, Zoloft + Paxil. Antidepressants increase the levels of serotonin and normalise the worry circuit.

- They prevent the re-absorption + breakdown of serotonin and this increases its level in the synapse and thus continues to stimulate the postsynaptic neuron. This compensates for whatever is wrong with the serotonin system in OCD.

-Dosage depends on the type of SSRI
