As the conflict in Iraq continues, public health authorities in the United States anticipate that many returning soldiers will suffer from posttraumatic stress disorder (PTSD). Initially, most of these veterans are likely to consult their primary care physicians about health problems. However, the diagnosis of PTSD is often missed in primary care settings. The author encourages physicians to become better prepared to recognize this disorder in their patients and initiate proper treatment or appropriate referral. Current diagnostic approaches and treatment modalities for combat-related PTSD are reviewed—with an emphasis on clinical procedures for the primary care physician.

In a study involving 746 veterans, Magruder et al¹ found that physicians in primary care clinics recognized PTSD in only 40 (46.5%) of 86 patients who were identified with this diagnosis by the Clinician Administered PTSD Scale for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition).

The present article reviews mental health problems that are commonly seen by primary care physicians as a result of patients' participation in combat, focusing on approaches to the diagnosis and management of PTSD, which is the most prominent of these disorders.

American soldiers face a number of stressors that may contribute to the development of PTSD, many of which are unique to modern warfare. Stressful war experiences described by veterans returning from the conflict in Iraq include the following:

• combat exposure—including such experiences as firing weapons and being fired upon; being in danger of injury or loss of life; seeing destroyed villages and refugees; and being exposed to the sights, sounds, and smells of human death
  
• life-threatening events, including fear and sustained anticipatory anxiety about exposure to combat
  
• concerns about possible exposure to biological, chemical, and radiological weapons, including fears about the long-term health effects of such exposures
  
• difficult living and working conditions, including lack of desirable food, lack of privacy, poor living arrangements, uncomfortable weather, cultural differences, long working hours, and boredom
  
• concerns about how deployment may adversely affect career, family, and other personal matters
  
• unpredictability of length of deployment, including the possible ongoing redeployment for National Guard and US Army Reserve troops
  
• sexual and gender harassment, particularly among enlisted women
  
• ethnocultural stressors for minority soldiers, particularly those of Arabic descent or faith²
  

In addition to these stressors, soldiers also face concerns regarding terrorist tactics. As widely noted in the public media, soldiers in these settings often have difficulty determining whether the civilians they encounter are would-be suicide bombers.³ Because of the changing nature of warfare in the 21st century,⁴ the "frontline" has subsumed individuals in many active-duty support roles that, when compared to combat-ready troops, had previously been considered "safe" (eg, truck drivers, medical personnel).² Finally, soldiers currently serving in the Middle East combat theater also confront the potential of abuse or execution if captured as well as the possible mutilation and desecration of their bodies by the hands of enemy combatants.

	Psychiatric Disorders Resulting From Exposure to Military Conflict

Modern warfare—with its atmosphere of confusion, uncertainty, and the always-present potential for injury and death—could easily result in mental distress and mental disorders for soldiers. A survey of more than 11,400 veterans of the 1991 Persian Gulf War revealed that approximately 10% of returning veterans had symptoms of PTSD.⁵ In a 2004 US Army study of more than 3,600 veterans returning from Afghanistan or Iraq, researchers found that the percentage of veterans meeting screening criteria for major depression, generalized anxiety, or PTSD was 9.3% for those who served in Afghanistan and 17.1% for those who were stationed in Iraq.⁶

The psychiatric differential diagnosis for military patients is broad and varies depending on several factors, including the type and severity of traumatic exposure and the time that has passed since the precipitating event.⁷ Following exposure to severe trauma, mental disorders tend to occur in three sequential phases.⁷ In the immediate phase—during or immediately after traumatic events—individuals may experience feelings of anxiety, confusion, disbelief, fear, and numbness. Such problems as acute stress disorder, adjustment disorders, brief psychotic disorder, substance abuse, and exacerbation of preexisting mental illness are considerations.⁷ In the delayed phase (generally up to 2 weeks after trauma), individuals may experience apathy, autonomic arousal, grief, intrusive thoughts, social withdrawal, or somatic symptoms. Differential diagnoses at this point include anxiety disorders, depressive disorders, psychotic disorders, somatoform disorders, and substance abuse, as well as early PTSD.⁷ Later, in the chronic phase (months to years after precipitating events), patients may report feelings of disappointment, resentment, sadness, and persistent intrusive symptoms. Diagnoses to consider in this phase include PTSD; depression, dysthymia, and other mood disorders; schizophrenia and other psychotic disorders; and substance abuse or dependence.⁷

Veterans seeking treatment in the civilian sector will usually be in the chronic phase of illness.⁷ Thus, the present article focuses on PTSD and related disorders, which are the most common mental health problems expected to occur in this cohort.⁷ Although this article focuses on treatment of veterans of modern warfare, the same principles of diagnosis and treatment may apply to any patient with PTSD, regardless of the type of stressor that induced the disorder.

Response to traumatic stress varies from person to person. Yet, under sufficient stress, anyone can succumb to mental disturbance. It is normal to have time-limited posttraumatic stress responses that do not persist or impair functioning.⁷ Such responses are often necessary for survival. However, when catastrophic stress overwhelms adaptive coping responses, posttraumatic psychiatric disorders result.⁷

Acute Stress Disorder
In the acute phase of abnormal response to trauma (<4 weeks after trauma), the cluster of symptoms is referred to as acute stress disorder.⁸ This disorder is rarely seen by primary care physicians. Based on the criteria established in the Text Revision of the DSM-IV,⁸ a patient diagnosed with acute stress disorder must, following a traumatic event, have at least three dissociative symptoms (eg, depersonalization or derealization, dissociative amnesia), one or more symptoms of reexperiencing the trauma (eg, flashback episodes), symptoms of anxiety or increased arousal (eg, exaggerated startle response), and marked avoidance of stimuli-arousing recollections of the trauma. These symptoms must cause clinically significant difficulties in functioning and persist from 2 days to 4 weeks.⁸ Acute stress disorder is considered a precursor to PTSD.⁸

Posttraumatic Stress Disorder
When the pathologic response to trauma lasts more than 4 weeks, it is referred to as PTSD.⁸ Patients with PTSD develop symptoms in three categories: reexperiencing the trauma, avoiding stimuli associated with the trauma, and increased autonomic arousal.⁸ Trauma may be reexperienced as distressing recollections and dreams, flashbacks (in which the patient may feel and act as if the trauma were recurring), and psychologic or physiologic stress reactions upon exposure to stimuli associated with the trauma. Symptoms of avoidance include efforts to refrain from thoughts or activities related to the trauma, reduced capacity to remember events related to the trauma, anhedonia, blunted affect, feelings of detachment or derealization, and a sense of a foreshortened future. Symptoms of increased arousal include exaggerated startle response, hypervigilance, insomnia, irritability, and outbursts of anger.⁸ To be diagnosed with PTSD, a patient must exhibit at least one symptom of reexperiencing, three symptoms of avoidance, and two symptoms of increased arousal—and these symptoms must persist for more than 1 month.⁸ In addition, the diagnosis of PTSD requires that the patient's disturbance cause "clinically significant distress of impairment in social, occupational, or other important areas of functioning."⁸ The DSM-IV-TR criteria for a diagnosis of PTSD are shown in Figure 1.

The four-question Primary Care Posttraumatic Stress Disorder (PTSD) Screen developed by the United States Department of Veteran Affairs' National Center for PTSD9 to enable physicians to detect this disorder in their patients quickly. Endorsement of any two items on the screen indicates a likelihood of a diagnosis of PTSD.

Patients with PTSD may seek consultation in a variety of ways. Although some patients will want to talk about their experiences, most patients will have difficulty discussing their thoughts and feelings about what happened to them.² It is important not to press traumatized patients too soon or too intensely to talk about their experiences. Rather, patients should be allowed to discuss their traumatic experiences when they are ready to do so. The National Center for PTSD² recommends that physicians begin the assessment process by concentrating on the immediate needs of the patient and by being prepared to explore the traumatic exposure later in the assessment process. Thus, assessment should start with stabilization and proceed in the following sequence²:

1. Address symptoms that require emergency intervention, such as suicidal or homicidal thoughts or acute psychotic symptoms.
   
2. Address symptoms that are most disruptive to the patient, such as those that interfere with psychosocial functioning.
   
3. Develop a case formulation and a comprehensive treatment plan. Several psychosocial and pharmacologic interventions may be considered.²
   

	Treatment Modalities and Psychosocial Interventions

Top Stressors Faced By Soldiers... Psychiatric Disorders Resulting... Assessment of PTSD in... Treatment Modalities and... Other War-Related Mental... Ongoing Support for Patients... Conclusions References

 
Psychologic and social interventions may be the treatment of first choice for many patients with PTSD. In some cases, these interventions are more valuable than medications.¹⁰ In most cases, they should be an important part of the patient's treatment. Establishing a trusting relationship between the patient and healthcare provider is always the first step in the initiation of any treatment, but developing such a relationship may be especially challenging with those patients who have experienced traumatic stress. Physicians should work from a patient-centered perspective to determine the current concerns of the patient.¹⁰ Practical help with specific issues can then be offered.¹⁰

Education for the Whole Patient: Psychoeducational Interventions
Unfortunately, patients may have misconceptions about mental illness and PTSD that can interfere with their ability to accept and adhere to effective treatment regimens. Patient education can help to remove many misconceptions and improve patients' levels of self-understanding and symptom recognition, as well as reduce the level of fear and shame they may feel about their symptoms.^10,11 Education empowers patients, providing them with knowledge about the causes of his or her symptoms, of what will happen in treatment, and of how recovery is expected to proceed. Patient education should stress the concept that many symptoms of PTSD are the result of reactions to stress. Patients should be encouraged to interpret their reactions as a response to overwhelming stress rather than as a personal weakness. This approach will often lessen the patient's fears about entering or maintaining treatment.^10,11

Coaching in alternative coping mechanisms may provide patients with practical techniques to deal with the intense emotional problems that they might be having. Coping skills that are commonly taught to patients with PTSD include anger management, anxiety management, communication improvement, and relaxation techniques.^10,11 Such training helps patients regain a sense of control over their emotions and related physical symptoms.

Families are intricately involved in the lives of traumatized patients. Both families and patients may benefit from family counseling, as well as couples counseling, parenting classes, and training in conflict resolution.^10,11 Family members may also be able to provide relevant patient history (eg, emotionality, drug abuse, sleep habits, socialization) that the patients themselves are unable or unwilling to report.

Cognitive restructuring is designed to help patients review and correct erroneous trauma-related beliefs by providing education about the relationships between thoughts and emotions, by exploring common negative thoughts held by traumatized patients, by identifying personal negative beliefs, by developing alternative interpretations, and by practicing new ways of thinking.^10,11 This treatment modality also involves individual self-monitoring of thoughts and the practice of learned techniques in real-life settings.^10,11 Finally, cognitive restructuring may help veterans deal with changed perceptions of personal identity caused by participation in combat.

Exposure therapy may be considered after patients are prepared to confront their trauma-related emotions and painful memories. This form of therapy is based on repeated verbalization of traumatic memories by patients.¹¹ Patients are repeatedly exposed to their own individualized fear stimuli until their fear responses are consistently diminished.¹¹ It is important that physicians providing this form of treatment have proper training and experience, however, because it has been found that a patient's condition may deteriorate if this type of therapy is used improperly.¹¹

Psychopharmacologic Intervention
The observation of physiologic alterations (eg, adrenergic hyperactivity), as well as psychologic alterations, associated with PTSD has led to the use of pharmacologic agents to treat patients with this disorder.¹² Pharmacotherapy should not be considered the primary modality for managing PTSD; it is one option among other potential treatment courses previously discussed. The most effective intervention for PTSD may involve a combination of pharmacotherapy and psychotherapeutic modalities.¹⁰ Several medications have been used to treat patients with PTSD, some of them based on well-designed clinical trials and others apparently based solely on anecdotal evidence.¹² Although, to date, only the antidepressants sertraline hydrochloride and paroxetine have been approved by the US Food and Drug Administration (FDA) for the treatment of patients with PTSD, clinical observation of psychophysiologic alterations associated with the disorder has led to the study of other antidepressants, mood-stabilizing agents, adrenergic-inhibiting agents, and antipsychotic agents.¹²

Antidepressants—The most frequently prescribed and most carefully studied pharmacologic agents used to treat patients with PTSD.¹² A growing body of literature provides evidence to consider antidepressants the pharmacologic treatment of first choice for managing the disorder.¹² Virtually every antidepressant available has been used in some context to attempt to manage the clinical symptoms of PTSD.¹²

Selective Serotonin Reuptake Inhibitors: The medications in this class of antidepressants inhibit the reuptake of serotonin by neurons, resulting in increased amounts of serotonin in synapses and improved functioning of serotonin in the central nervous system.^12,13 Serotonin has a regulatory effect on norepinephrine activity through the locus ceruleus, helping to modulate excessive external stimuli and reduce feelings of fear. Research and clinical practice have shown that selective serotonin reuptake inhibitors (SSRIs) are effective for managing anxiety, depression, and panic attacks.¹²

There are several reasons that SSRIs are the current medications of choice for managing PTSD.¹³ They ameliorate all three PTSD symptom categories. They are effective in managing the psychiatric disorders that often occur comorbidly with PTSD (eg, depression, panic disorder, social phobia). They may reduce such clinical symptoms as aggressive, impulsive, and suicidal behaviors that often complicate management of PTSD, and they cause relatively few adverse effects.¹³

Open-label and double-blind trials have demonstrated that the SSRIs citalopram hydrobromide, fluoxetine, fluvoxamine maleate, paroxetine, and sertraline are all effective in the treatment of patients with PTSD.¹³ In addition, paroxetine and sertraline have been assessed in large multisite double-blind controlled trials, and, as previously mentioned, the FDA has approved each of these medications for treatment of patients with major symptom clusters of PTSD.¹⁴

The adverse effects of paroxetine, sertraline, and other SSRIs are generally more tolerable for patients than those of other categories of antidepressants.¹² Escitalopram oxalate, a relatively new SSRI, may also eventually prove beneficial for patients with PTSD, but clinical experience using this drug to manage PTSD is limited at this time.¹⁵

Tricyclic Antidepressants: In addition to antidepressant effects, tricyclic antidepressants (TCAs) have antipanic effects.^16-18 Because of the resemblance between panic attacks and severe PTSD arousal symptoms, TCAs may be helpful for managing PTSD. Small controlled clinical trials have been conducted using the TCAs amitriptyline hydrochloride, imipramine, and desipramine.^16-18 Amitriptyline, compared with placebo, in 46 veterans with PTSD resulted in better outcomes on the Hamilton Depression, Hamilton Anxiety, Clinical Global Impression, and Impact of Event scales after 8 weeks of treatment.¹⁶ A study of 34 veterans with PTSD who were treated with imipramine, the monoamine oxidase inhibitor (MAOI) phenelzine, or placebo showed global assessment improvement in 75% of patients taking imipramine, 64% of patients taking phenelzine, and 27% of patients taking placebo.¹⁷ An investigation of 18 veterans with PTSD who were treated with desipramine showed improvement in symptoms of depression but of no other symptoms related to PTSD.¹⁸

Tricyclic antidepressants carry the risk of cardiac conduction disturbances, sedation, and overdose.^16-18 Because SSRIs and other antidepressants that cause much fewer adverse effects than TCAs are now available, TCAs are no longer commonly prescribed for depression or related mental disturbances.^12,13

Monoamine Oxidase Inhibitors: Like TCAs, MAOIs produce antipanic effects. They have been used to treat patients with mixed conditions of anxiety and depression.¹⁹ A quantitative analysis by Southwick et al,¹⁹ which included 15 mostly open-label clinical trials of TCAs and MAOIs, found that 82% of patients with PTSD who were treated with the MAOI phenelzine reported a reduction in intrusive symptoms, compared with 45% of patients treated with a TCA. Unfortunately, MAOIs must be used with caution because of the risk of hypertensive crisis.¹⁹ Thus, they currently are rarely prescribed.

Moclobemide, a reversible inhibitor of monoamine oxidase type-A, is associated with less risk of hypertensive crisis and has been shown in clinical studies to reduce symptoms in all three PTSD symptom categories.²⁰ However, moclobemide is not yet available in the United States.

Other Antidepressants: Several other antidepressants have been investigated for the treatment of patients with PTSD. For example, nefazodone and trazodone hydrochloride are potentially useful because they increase serotonin activity, though not selectively. In six open-label trials reported by Hidalgo et al,²¹ nefazodone was found to reduce anxiety, nightmares, and global ratings in patients with PTSD. In addition, it was found to possibly help reduce PTSD-related sleep disturbance.²¹ As of 2001, however, the FDA has required manufacturers and pharmacists to use a black box warning label on nefazodone because of potential risk for hepatotoxicity and liver failure.²² Trazodone has not been proven significantly effective in management of the core symptoms of PTSD.¹⁴ Furthermore, because it has a somewhat sedative effect, some clinicians prescribe it in low dosages to treat patients with insomnia.¹⁴

Bupropion, duloxetine hydrochloride, mirtazapine, and venlafaxine hydrochloride are other antidepressants that are potentially useful for treating patients with PTSD.²³ However, none of these medications have been tested in clinical trials for PTSD. Neither are they approved by the FDA for treatment of patients with PTSD.

Mood-Stabilizing Agents—The sensitization and kindling of the limbic system has been hypothetically proposed as a cause of physiologic changes in PTSD.²⁴ In this model, repeated traumatic stress leads to sensitization and kindling, with a spontaneous limbic discharge resulting from sensitization.²⁴ Mood-stabilizing agents (ie, medications commonly used as anticonvulsants) have the potential to prevent this sensitization and kindling or to modulate these phenomena after they occur. Therefore, they may ameliorate PTSD symptoms.

Investigations involving mood-stabilizing medications for PTSD management have been limited primarily to open-label studies.^14,25,26 Carbamazepine has strong antikindling properties and has been effective in PTSD management in several small open-label clinical trials.²³ Gabapentin, lamotrigine, lithium carbonate, topiramate, and valproate sodium have also shown effectiveness in PTSD management in at least one open-label study each.^14,26 Thus, despite a strong theoretical basis, there has been only a small amount of systematic investigation to demonstrate the value of mood stabilizers for the treatment of patients with PTSD.

Adrenergic Inhibitors—Autonomic dysregulation is thought to explain many of the physiologic changes seen in patients with PTSD.²⁷ Patients with the disorder have elevated levels of plasma norepinephrine at rest, substantial norepinephrine increases when exposed to trauma-related stimuli, and down regulation (ie, decrease in sensitivity) of norepinephrine receptors in platelets due to increased circulation of norepinephrine.²⁷ Sustained periods of increased norepinephrine levels are thought to increase the risk of PTSD by contributing to overconsolidation of memories of the traumatic event.²⁸

Medications that decrease adrenergic (ie, norepinephrine-mediated) activity may reduce anxious arousal in patients with PTSD. Propranolol hydrochloride and other ß-adrenergic blockers reduce the peripheral effects of norepinephrine.^29,30 Propranolol has been shown to improve PTSD symptoms in one small clinical trial,²⁹ but it was not helpful in another small trial.³⁰ Because 2-adrenergic receptor agonists (eg, clonidine, guanfacine hydrochloride) act at noradrenergic autoreceptors to inhibit the firing of cells in the locus ceruleus, they may also be responsible for reducing the release of norepinephrine in the brain.³¹ In small open-label clinical trials, clonidine showed promise in reducing symptoms among patients with PTSD.³¹ The use of prazosin hydrochloride, an 1-adrenergic receptor antagonist, resulted in robust improvement of several PTSD symptoms, particularly sleep quality and reduction of nightmares, in a double-blind crossover protocol by Raskind et al.³²

Antianxiety Agents—Benzodiapines and buspirone hydrochloride are among the medications that are not currently recommended for treating patients with PTSD.

Benzodiazepines: Frequently prescribed to reduce anxiety and promote sleep in patients.³³ However, their efficacy in managing the specific symptoms of PTSD has not been established. In fact, they may worsen the disorder by virtue of their dissociative and disinhibitory properties.³³ In addition, their potential for abuse through addiction remains a major area of concern.³³ Therefore, benzodiazepines cannot be recommended for patients with PTSD.

Buspirone: A nonaddictive medication widely used to treat patients with anxiety.³⁴ However, like benzodiazepines, the effectiveness of buspirone for managing the core symptoms of PTSD remains to be established.

Antipsychotic Medications—Although psychotic symptoms are not included in the diagnostic criteria for PTSD, some patients with PTSD may experience brief psychotic episodes and also have psychotic symptoms as part of a comorbid disorder.⁴ Use of older, "conventional" antipsychotic medications (eg, haloperidol) is not recommended because of the risk of adverse effects and the availability of more suitable alternatives.³⁵ Preliminary results suggest that the newer, atypical antipsychotic drugs (eg, olanzapine, quetiapine fumarate, risperidone) may be useful for patients with PTSD and psychotic symptoms to augment treatments with first- or second-line medications.³⁵ Such patients include those experiencing agitation, dissociation, hypervigilance, intense paranoia, or brief psychotic reactions associated with PTSD. Atypical antipsychotic medications may cause serious adverse effects, including tardive dyskinesia and neuroleptic malignant syndrome, though these effects are less likely than with conventional antipsychotic medications.³⁵ Most atypical antipsychotic drugs may also cause weight gain.³⁵

The goal of the pharmaceutical management of PTSD is symptom reduction and stabilization. Even if all symptoms do not completely resolve, patients may still benefit from medications by getting a good night's sleep and being less anxious and irritable. Figure 3 summarizes some of the medications that have proven effective or that are potentially effective for the clinical management of PTSD. Acute PTSD responds better to pharmaceutical management than does chronic PTSD, and, generally, the earlier treatment begins, the better.^10,12,33

View larger version (47K): [in this window] [in a new window]   Figure 3. Medications with proven or potential effectiveness in the management of posttraumatic stress disorder (PTSD).12 The effectiveness of selective serotonin reuptake inhibitors (SSRIs) has been proven in large clinical trails. Tricyclic antidepressants (TCAs) have produced moderate improvement in symptoms in small controlled clinical trails. The effectiveness of mood stabilizers has been suggested in small open-label clinical trails. Adrenergic inhibitors have shown promise in small open-label or controlled trials. The effectiveness of antianxiety agents has not yet been established in clinical trials. Preliminary results indicate that atypical antipsychotic medications may be useful to augment treatment with other medications. *This medication is approved by the US Food and Drug Administration for the management of PTSD. This medication is not recommended for treating patients with PTSD because of risk of dependency.

In all cases, physicians need to be aware of potential adverse effects associated with the medications prescribed. Appropriate patient monitoring is also essential. Pharmacotherapy should be used in combination with psychosocial treatment modalities as well as other treatment options to ensure a comprehensive approach to patient care.

Osteopathic Manipulative Treatment and PTSD
To date, there have been no studies investigating the effectiveness of osteopathic manipulative treatment (OMT) in patients with PTSD. Nevertheless, it seems logical that OMT could benefit these patients. One might hypothesize that patients with posttraumatic stress are likely to have increased sympathetic nervous system activity and associated somatic dysfunction, particularly in the thoracolumbar region. Uncomfortable paravertebral muscle spasm may accompany these dysfunctions. Thus, in my view, addressing these dysfunctions with appropriate osteopathic manipulative techniques could aid in the healing process—as well as help improve patient-physician rapport and patient compliance with supplemental therapeutic modalities.

Posttraumatic stress disorder is the primary war-related mental disorder seen in veterans who returned from the 1991 Persian Gulf War.⁵ However, other mental disorders may occur in the context of combat and should be given appropriate consideration. With PTSD, comorbidity is the rule, not the exception.⁸ Prior to a conclusive diagnosis of PTSD, patients should receive a thorough psychiatric and medical examination to rule out other possible problems. As previously noted, a number of psychiatric disorders may occur in the postcombat setting, including anxiety and mood disorders, personality disorders, psychosis, and substance abuse.^2,5-8,36 In addition, general medical conditions—including anemia, arthritis, asthma, back pain, diabetes, kidney disease, lung disease, and ulcers—are common among patients with PTSD.³⁷ In many cases, the comorbid conditions likely prompt initial requests for treatment, especially in the primary care setting. These complaints should be properly assessed and never assumed to be exclusively psychogenic in origin.

A number of mental disorders, including depression, mania, panic disorder, and schizophrenia, commonly have an age of onset between the late teens and early 30s—the same age range of many individuals engaged in the nation's current military conflicts.^2,5-8 In a person who is susceptible to a particular disorder, that disorder could be precipitated by the stresses of combat situations. In addition, mental disorders already present, but in latent or controlled states, could worsen as a result of the impact of such trauma.^2,5-8 Thus, it is important for primary care physicians to consider the full range of possible psychiatric disorders before making a diagnosis.

Combat veterans with PTSD may present a unique challenge to primary care physicians, with psychiatric consultation usually being necessary. Referral to a Veterans Affairs (VA) medical center may be an early consideration for many patients. The US Department of Veterans Affairs has many physicians with treatment expertise in PTSD, and virtually all veterans returning from the current conflicts will be eligible for VA treatment. Because PTSD interferes with social functioning, it is important to encourage these patients to avoid social isolation and withdrawal. Veterans often report that the opportunity to connect with and be supported by other veterans is a valued experience.¹⁰ Such an experience may be difficult to accomplish outside a VA facility or other setting devoted to the needs of returning veterans.

A number of helpful online resources on PTSD are available for both physicians and veterans. A list of these resources is presented in Figure 4.

Primary care physicians who see patients that have returned to the United States after military service in Afghanistan and Iraq should consider the possibility that active-duty stressors have contributed to patient symptoms. With these events in mind, physicians should make respectful and gentle inquiries as to patient history so that appropriate treatment can be initiated and necessary referrals provided quickly.

The principles discussed in the current article are presented primarily in the context of combat-related PTSD. However, the same principles can apply to the treatment of all patients with PTSD—regardless of the nature of the trauma. Some examples of noncombat-related causes of PTSD include physical assault, exposure to natural disasters, and terrorist attacks. Patients who have experienced such trauma may benefit from the same types of interventions provided to military veterans with PTSD.
