Nonpathologic Postdeployment Transition Symptoms in Combat National Guard Members and Reservists

The rigid dichotomy between combat deployment and postdeployment environments necessitates a multitude of cognitive, behavioral, and emotional adjustments for National Guard members and reservists to resume postdeployment civilian lifestyles successfully. Reacclimating to the postdeployment world is not a quick process for these veterans because of the time required to adjust from a deeply ingrained military combat mentality to civilian life. The process of this reintegration into the civilian world is known as postdeployment transition.

More than half of post-9/11 combat veterans report at least some difficulty with postdeployment transition.^1,2 Frequently encountered symptoms of this period include impaired sleep, low frustration tolerance, decreased attention, poor concentration, short-term memory deficits, and difficulty with emotional regulation.^1,3,4 Veterans will have difficulty reintegrating into the family unit and society without successful coping strategies to address these symptoms. If transition symptoms are prolonged, veterans are at risk for developing chronic adjustment difficulty or mental health issues.

Although there is significant attention paid to postdeployment adjustment by military family advocacy groups, there is little information in the medical literature on what constitutes common, nonpathologic postdeployment reactions among combat veterans. Frequently, when postdeployment transition symptoms are discussed, the medical literature tends to explain these in the context of a mental health disorder, such posttraumatic stress disorder (PTSD) or a cognitive injury, such as traumatic brain injury.^5-8 Without a balanced understanding of normal postdeployment transitions, a health care provider (HCP) inappropriately may equate transition symptoms with the presence of mental health disorders or cognitive injury and medicalize the coping strategies needed to promote healthy adjustment.

The purpose of this article is to promote HCP awareness of common, nonpathologic postdeployment transition symptoms in combat veterans who are National Guard members or reservists. Such knowledge will enable HCPs to evaluate transition symptoms among these combat veterans reentering the civilian world, normalize common transition reactions, and recognize when further intervention is needed. This article reflects the author’s experience as a medical director working in a VA postdeployment clinic combined with data available in the medical literature and lay press.

Postdeployment Transition Symptoms

Dysregulation of emotional expression in returning combat veterans potentially can be present throughout the postdeployment period of adjustment. Although individual experiences vary widely in intensity and frequency, during postdeployment transition veterans often note difficulty in adjusting emotional expression to match that of nonmilitary counterparts.^1,9-11 These difficulties usually fall into 2 broad categories: (1) relative emotional neutrality to major life events that cause nonmilitary civilians great joy or sadness; and (2) overreaction to trivial events, causing significant irritation, anger, or sadness that normally would not produce such emotional reactions in nonmilitary civilians. The former is largely overlooked in medical literature to date except in relation to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) categories, and the latter is often described in limited terms as increased irritability, restlessness, and low frustration tolerance. This emotional dysregulation creates confusing paradoxes for veterans. For example, a veteran might feel no strong emotion when notified of the death of a close relative and yet cry uncontrollably while watching a sad scene in a fictional movie.

Sleep difficulties are intrinsic to the postdeployment period.^9-12 Sleep-wake cycles often are altered, reflecting residual effects of the rigid schedules required by military duties and poor sleep hygiene in the combat theater. Inadequate, nonrestful sleep is frequently reported on return to the civilian world. Difficulty falling asleep or difficulty staying asleep also commonly occurs. Nightmares may be present.

Transient difficulty with concentration and attention is often prominent within the postdeployment transition period.^9-11,13 Manifestations are variable, but problems with focusing on minor tasks are commonly reported. A more intense effort to master new concepts may be required. Learning styles developed during predeployment phases may be altered so that more conscious effort is required to comprehend and retain new information.

Short-term memory frequently may be affected during postdeployment transition.^9-11,13 Veterans often report postdeployment difficulty in recalling appointments or tasks that must be completed even if they had a keen sense of memory during predeployment or deployment. Veterans also may have difficulty recalling the details of specific routines that were done without hesitation during deployment. Compared with predeployment time frames, veterans may exert greater effort to recall newly learned material.

Automatic behaviors necessary for survival in a combat theater still may be prominent in the postdeployment period.^10,11,14 Aggressive driving required to avoid deployment ambush may be problematic during the postdeployment transition. Steering clear of any roadside trash may be a residual instinctive drive postdeployment because of the risk of improvised explosive devices concealed by debris in the combat theater. Veterans may avoid sitting with their back to the exit as the result of military safety training. Carrying weapons to ensure safety may be a compelling urge, because being armed and ready at all times was necessary for survival during deployment. Avoiding large crowds may be another strong tendency, because throngs of people were associated with potential danger in the combat theater.

Decision making may be challenging to resume in the postdeployment phase.^9-11,15 In the deployment theater, time is relativel structured with rules in place, whereas at home veterans face a myriad of choices and decisions that must be made in order to complete the responsibilities of everyday living. As a result, making decisions about what item to buy, which clothes to wear, or what activities to prioritize, though relatively minor, can be a source of significant frustration. It may be difficult to independently navigate a realm of options available for new employment, schooling, or benefits, especially when there is little or no prior experience with these issues.
