Relationship between etiology and therapeutic approach Disclaimer: No 1 treatment works for everyone Identifying a specific cause is reductionist Can one truly treat symptoms when the “causes” are unknown Primary therapeutic approach aimed to reduce greatest risk factor Culture affects beliefs about causes and treatments Gender Desire to locate causes is a highly western phenomenon Eclectic approach works well
Relationship between etiology and therapeutic approach Cont’d Low levels of Serotonin are present in PTSD victims Use of SSRIs to help Serotonin stay in the synapse longer would be one way etiology would cause a therapeutic approach Low education about PTSD and an inability to cope with the traumatic event Use of Prolonged Exposure (PE) to educate patient and then enhance their ability to face the traumatic event so that they can move on with daily life Low levels of cortisol are also present Glucocorticoid provides a dose of corticosterone to boost cortisol levles and has worked in rats There are many different relationships that exist and since PTSD is complex and relatively new. Researchers have not found an optimal treatment for PTSD, AND SYMPTOMS ARE WHAT ARE ULTIMTELY REDUCED RATHER THAN THE MENTAL ILLNES ITSELF
