Aging and Trauma: Post Traumatic Stress Disorder Among Korean War Veterans
Pharmacotherapy
There is very little empirical evidence guiding pharmacologic approaches to PTSD in older veterans. This population is at increased risk for many comorbidities, and pharmacologic treatments many require dosage adjustments, as is the case for any geriatric patient. Selective serotonin reuptake inhibitor (SSRI) and serotonin norepinephrine reuptake inhibitor (SNRI) medications have been proposed for some cases of PTSD.59,60 Health care providers may consider the SSRIs escitalopram or sertraline preferentially given their decreased potential for drug-drug interactions, anticholinergic effects, or cardiac toxicity compared with that of other drugs in this class.60,61 As venlafaxine can increase blood pressure, especially at higher doses, prescribers may choose duloxetine as an alternative if a SNRI is indicated.60 For veterans when prazosin is being considered for nightmare control, monitoring for hypotension, orthostasis, and the administration of other antihypertensives or prostatic hypertrophy medications is necessary.61 The use of benzodiazepines, while not recommended for PTSD, should be viewed with even greater trepidation in a geriatric population given enhanced risk of falls and confusion in the geriatric veteran population.60,62
Conclusions
Many of the oldest veterans (aged > 80 years) are from the Korean War era. The harsh and unique nature of the war, as well as the differences in context and support from the US public, and the outcome of the war, may have all contributed to and elevation of “combat fatigue” and PTSD among combat veterans from the Korean War. As the “forgotten war” cohort also has been forgotten by researchers, relatively little is known about posttraumatic stress sequelae of these veterans in the decades following the war.
From available evidence, we can readily surmise that problems were underrecognized and suboptimally diagnosed and treated. There is tentative evidence supporting the use of standard interviews and rating scales, such as the CAPS, M-PTSD, and PCL, but lower cut-scores than applied with Vietnam and later veteran cohorts are generally recommended to avoid excessive false negative errors. In terms of psychotherapy treatment, there is again a stark paucity of systematic research, but the limited evidence from studies of PTSD treatment in older adults from the general population tentatively support the acceptability and potential efficacy of recognized evidence-based trauma-focused psychotherapies for PTSD. Research on medication treatment is similarly lacking, but the general recommendations for the use of SSRI or SNRI medications seem to be valid, at least in our clinical experience, and the general rules for geriatric psychopharmacology definitely apply here—start low, go slow.
There are several important avenues for future research. Most pressing among these are establishing the effectiveness of existing treatments, and the modifications that may be needed in the broader context of the above factors, as well as the physical and cognitive changes associated with advanced age. Further research on the phenomenologic aspects of PTSD among Korean War and subsequent cohorts are also needed, as the information obtained will not only guide more effective personalized treatment of the Korean War veterans who remain with us, but also inform future generations of care in terms of the degree and dimensions of variability that may present between cohorts and within cohorts over the life span.
