Resumo de Recurso
the biological approach to treating OCD
Drug Therapy
aims to increase or decrease levels of neurotransmitters
SSRI
work on the serotonin system in the brain
how? serotonin
serotonin - released by presynaptic neurons, travels across synapse
neurotransmitter conveys the signals to postsynaptic neurons
then reabsorbed by presynaptic neuron (then broken down and reabsorbed)
how? SSRI
prevents reabsorption of presynaptic neuron
increases level in synapse
3 -4 months of daily use
combining SSRIs & CBT
drugs reduce emotional symptoms
can engage in CBT better
