Posttraumatic stress disorder (PTSD) occurs in an estimated 8% of men and 20% of women who are exposed to traumatic events. PTSD is a trauma- and stress-related disorder associated with significant psychosocial morbidity, substance abuse, and other negative physical health outcomes. The hallmarks of PTSD include exposure to a traumatic event; reexperiencing the event or intrusion symptoms; avoidance of people, places, or things that serve as a reminder of the trauma; negative mood and thoughts associated with the trauma; and chronic hyperarousal symptoms. Self-report questionnaires can assist clinicians in identifying anxiety problems associated with traumatic events. For patients who meet criteria for PTSD, trauma-focused psychotherapy and pharmacotherapy improve symptoms. Benzodiazepines and atypical antipsychotics are not recommended because studies have shown that adverse effects outweigh potential health benefits. Primary care physicians should monitor patients with PTSD for comorbid conditions such as substance abuse, mood disorders, and suicidality, and should refer patients to behavioral health specialists and support groups when appropriate.

Posttraumatic stress disorder (PTSD) is a trauma- and stress-related disorder that has historically been diagnosed in combat veterans, but also occurs after many other types of traumatic events (Figure 1). It is under-recognized and undertreated in primary care practices.1,2 To improve outcomes in patients with PTSD, this article provides a practical approach to the recognition, diagnosis, and multidisciplinary treatment of PTSD.

Diagnostic Criteria

PTSD is characterized by exposure to a traumatic event and the subsequent development of four general symptom domains: reexperiencing the event or intrusion symptoms; avoidance of people, places, or things that serve as a reminder of the trauma; negative changes in mood and thoughts associated with the event; and chronic hyperarousal symptoms (Table 1).3 Traumatic events generally involve threats to life, sense of personal safety or security, or physical integrity. A related condition, acute stress disorder, is distinguished from PTSD by the presence of similar symptoms (with the addition of dissociation) that last for less than one month.4 PTSD is diagnosed only if symptoms persist beyond one month after the event.

Table 1.

Diagnostic Criteria for Posttraumatic Stress Disorder in Persons Older Than Six Years

A. Exposure to actual or threatened death, serious injury, or sexual violence in one (or more) of the following ways:

1. Directly experiencing the traumatic event(s).

2. Witnessing, in person, the event(s) as it occurred to others.

3. Learning that the traumatic event(s) occurred to a close family member or close friend. In cases of actual or threatened death of a family member or friend, the event(s) must have been violent or accidental.

4. Experiencing repeated or extreme exposure to aversive details of the traumatic event(s) (e.g., first responders collecting human remains; police officers repeatedly exposed to details of child abuse).

Note: Criterion A4 does not apply to exposure through electronic media, television, movies, or pictures, unless this exposure is work related.

B. Presence of one (or more) of the following intrusion syndromes associated with the traumatic event(s), beginning after the traumatic event(s) occurred:

1. Recurrent, involuntary, and intrusive distressing memories of the traumatic event(s).

Note: In children older than six years, repetitive play may occur in which themes or aspects of the traumatic event(s) are expressed.

2. Recurrent distressing dreams in which the content and/or affect of the dream are related to the traumatic event(s).

Note: In children, there may be frightening dreams without recognizable content.

3. Dissociative reactions (e.g., flashbacks) in which the individual feels or acts as if the traumatic event(s) were recurring. (Such reactions may occur on a continuum, with the most extreme expression being a complete loss of awareness of present surroundings.)

Note: In children, trauma-specific reenactment may occur in play.

4. Intense or prolonged psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event(s).

5. Marked physiological reactions to internal or external cues that symbolize or resemble an aspect of the traumatic event(s).

C. Persistent avoidance of stimuli associated with the traumatic event(s), beginning after the traumatic event(s) occurred, as evidenced by one or both of the following:

1. Avoidance of or efforts to avoid distressing memories, thoughts, or feelings about or closely associated with the traumatic event(s).

2. Avoidance of or efforts to avoid external reminders (people, places, conversations, activities, objects, situations) that arouse distressing memories, thoughts, or feelings about or closely associated with the traumatic event(s).

D. Negative alterations in cognitions and mood associated with the traumatic event(s), beginning or worsening after the traumatic event(s) occurred, as evidenced by two (or more) of the following:

1. Inability to remember an important aspect of the traumatic event(s) (typically due to dissociative amnesia and not to other factors such as head injury, alcohol, or drugs).

2. Persistent and exaggerated negative beliefs or expectations about oneself, others, or the world (e.g., “I am bad,” “No one can be trusted,” “The world is completely dangerous,” “My whole nervous system is permanently ruined”).

3. Persistent, distorted cognitions about the cause or consequences of the traumatic event(s) that lead the individual to blame himself/herself or others.

4. Persistent negative emotional state (e.g., fear, horror, anger, guilt, or shame).

5. Markedly diminished interest or participation in significant activities.

6. Feelings of detachment or estrangement from others.

7. Persistent inability to experience positive emotions(e.g., inability to experience happiness, satisfaction, or loving feelings).

E. Marked alterations in arousal and reactivity associated with the traumatic event(s), beginning or worsening after the traumatic event(s) occurred, as evidenced by two (or more) of the following:

1. Irritable behavior and angry outbursts (with little or no provocation) typically expressed as verbal or physical aggression toward people or objects.

2. Reckless or self-destructive behavior.

3. Hypervigilance.

4. Exaggerated startle response.

5. Problems with concentration.

6. Sleep disturbance (e.g., difficulty falling or staying asleep or restless sleep).

F. Duration of the disturbance (Criteria B, C, D, and E) is more than one month.

G. The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

H. The disturbance is not attributable to the physiological effects of a substance (e.g., medication, alcohol) or another medical condition.

Specify whether:

With dissociative symptoms: The individual's symptoms meet the criteria for posttraumatic stress disorder, and in addition, in response to the stressor, the individual experiences persistent or recurrent symptoms of either of the following:

1. Depersonalization: Persistent or recurrent experiences of feeling detached from, and as if one were an outside observer of, one's mental processes or body (e.g., feeling as though one were in a dream; feeling a sense of unreality of self or body or of time moving slowly).

2. Derealization: Persistent or recurrent experiences of unreality of surroundings (e.g., the world around the individual is experienced as unreal, dreamlike, distant, or distorted).

NOTE: To use this subtype, the dissociative symptoms must not be attributable to the physiological effects of a substance (e.g., blackouts, behavior during alcohol intoxication) or another medical condition (e.g., complex partial seizures).

Specify if:

With delayed expression: If the full diagnostic criteria are not met until at least six months after the event (although the onset and expression of some symptoms may be immediate).

Of note, the recently published fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) had several changes to the exposure criteria. The previous version of the DSM required the individual to directly experience or witness the event and to experience a sense of helplessness. However, recent evidence showed that persons working in military and first responder occupations did not report the typical responses of fear, helplessness, or horror that are common in persons who have experienced traumatic events.5,6 In response to these findings, the DSM-5 removed the helplessness requirement and broadened the definition to include the types of repetitive threats experienced by persons in these professions.3

Onset and Course

Emotional and physical responses vary considerably after acute exposure to traumatic stressors, with some persons not becoming symptomatic until years after the event. Spontaneous recovery usually occurs. However, if coping mechanisms are inadequate, psychological distress can intensify over time, leading to the development of PTSD. Although there is no clear timeline for symptom development, studies in military populations returning from combat zones have shown an increase in symptoms three to six months after return.7 Additionally, several studies have indicated that approximately one-third of persons with PTSD will develop chronic symptoms.8,9

Epidemiology and Risk Factors

The lifetime risk of being exposed to a traumatic stressor is high (60.7% for men, 51.2% for women), but only an estimated 8% of exposed men and 20% of exposed women develop PTSD.9 The overall lifetime prevalence of PTSD in the United States is 8%.9 However, prevalence estimates for combat veterans and survivors of severe natural or man-made disasters are much higher.9 Identification and treatment are further complicated by the fact that most persons with PTSD do not seek mental health assistance.10

Risk factors associated with progression to chronic PTSD are not well understood. Although there may be a genetic component in a small percentage of cases, environmental and biologic factors (e.g., poor psychosocial support, history of trauma, history of mental health problems) are also important risk factors.11 Resiliency development and positive psychology programs have been emphasized for persons with high-risk professions, but there is no evidence that these programs prevent PTSD.12

Diagnostic Approach

Early identification and treatment are important in improving the prognosis.13,14 Clinicians should have a high index of suspicion for PTSD in patients at risk, including those with a history of sexual assault or military service in a combat zone, and survivors of natural disasters. Although most persons do not develop PTSD after trauma exposure and screening has not been shown to improve health outcomes, guidelines from the U.S. Departments of Defense and Veterans Affairs recommend that all new patients with a history of trauma exposure be screened for symptoms of PTSD initially, and then on an annual basis or more frequently if indicated.14 There is insufficient evidence to recommend specific screening for persons of any ethnicity, race, or sex.14

Self-report questionnaires can assist clinicians in identifying anxiety associated with traumatic events. The most commonly used tools are the Primary Care PTSD Screen15 and the 17-item PTSD Checklist (available on pages 209 and 210, respectively, of the Department of Defense and Veterans Affairs guideline at http://www.healthquality.va.gov/ptsd/cpg_PTSD-FULL-201011612.pdf), and the Short Screening Scale for PTSD.16 However, there is insufficient evidence to recommend one tool over another.14  These tools are not diagnostic for PTSD, but indicate the presence of symptoms consistent with the disorder (Table 213). If the results are positive, a more thorough assessment should be conducted.13,14 Clinicians should assess the time of onset; frequency, course, and severity of symptoms; level of distress; and degree of functional impairment.

PTSD is associated with several comorbid physical and psychiatric conditions that can adversely affect treatment response unless they are addressed. The most common psychiatric comorbidities include substance abuse, mood disorders, and anxiety disorders.9 In addition, physicians should screen for suicidal ideation; as many as one in five patients with PTSD may attempt suicide.14,17 Generalized physical symptoms are also common among persons exposed to trauma.18,19 Physical injuries from the traumatic event are risk factors for PTSD.

Management

The physician should educate the patient and his or her family about PTSD symptoms, other potential consequences of trauma exposure, and any comorbid conditions.13,14,20,21 Because patients often are reluctant to discuss traumatic events and may avoid treatment as a result, it is important to elicit patient preferences for treatment interventions. Other factors that influence treatment choices include locally available resources, individual physicians' comfort level and experience, and severity of symptoms.

Trauma-focused psychotherapy and pharmacotherapy are first-line treatment options, but often must be combined with management of comorbid medical problems, such as chronic pain or sleep disturbance. Many persons with PTSD will attempt self-treatment methods, such as substance use. Physicians should have a low threshold for involving behavioral health specialists in PTSD management in the presence of comorbid substance abuse or psychiatric conditions. Patients who have substance use disorders should attempt a detoxification program, if necessary, and should be referred to a substance abuse or dual-diagnosis treatment program.

PSYCHOLOGICAL INTERVENTIONS

Although there is insufficient evidence that psychotherapy is more effective than medical therapy in the treatment of PTSD, most patients should be offered psychotherapy to address the specific symptoms of PTSD and any comorbid conditions. Trauma-focused psychotherapies that include narrative exposure, in vivo exposure (i.e., directly confronting anxiety triggers), cognitive restructuring, and relaxation techniques are the most effective.14,2025 Some examples of therapies that include these components are prolonged exposure, cognitive processing therapy, and eye movement desensitization and reprocessing. Other potentially effective therapies include imagery rehearsal, brief psychodynamic therapy, and hypnosis.14 Psychoeducation and supportive interventions are also important components of therapy. PTSD can have significant effects on the spouses, children, and families of persons affected; therefore, referral to a marital or family therapist may also be indicated.14

PHARMACOTHERAPY

Table 3 lists medications available for the treatment of PTSD.14,2633 [corrected] General guidelines include optimizing monotherapy; continuing the dosage for four weeks if the patient responds to treatment and tolerates the medication; switching to another agent if the patient does not tolerate the medication; and increasing the dosage or switching to another medication if no improvement is noted after eight weeks of therapy.14 Treatment effectiveness is measured by subjective and objective symptom reduction.

Antidepressants. Selective serotonin reuptake inhibitors and serotonin–norepinephrine reuptake inhibitors have the most evidence supporting their use in the treatment of PTSD; sertraline (Zoloft) and paroxetine (Paxil) are approved by the U.S Food and Drug Administration for this use.26,27 Selective serotonin reuptake inhibitors and serotonin–norepinephrine reuptake inhibitors may be prescribed as first-line therapy because there is no direct evidence that psychotherapy is more effective.14 These medications help with most PTSD symptoms, including intrusive thoughts and flashbacks, irritability and anger, problems concentrating, hyperarousal, chronic restlessness and anxiety, and depressed mood.13,14,26,27 Patients should be counseled that it may take six to eight weeks to achieve full therapeutic benefit,34 and that suddenly stopping therapy can result in a discontinuation syndrome that may include anxiety, insomnia, depression, irritability, mood lability, vivid dreams, tremors, fatigue, lethargy, and dizziness.34 These symptoms may be mistaken as a worsening of PTSD symptoms. Other antidepressants may also be effective, including mirtazapine (Remeron), nefazodone, tricyclic antidepressants, and monoamine oxidase inhibitors.28 Safety considerations, adverse effects, and psychiatric and medical comorbidities make these second-line medication choices.13,14,29

Augmenting Agents. Augmentation with other medications may be necessary if symptoms persist despite first-line pharmacotherapy. The alpha-adrenergic blocker prazosin (Minipress) alleviates sleep disturbance caused by nightmares.14,30,31 The effectiveness of other alpha-adrenergic blockers, alpha2 agonists (e.g., clonidine [Catapres], guanfacine [Tenex]), and beta antagonists (e.g., propranolol, atenolol [Tenormin]) in the treatment of PTSD is unknown.14,30

Benzodiazepines have been used to treat symptoms of hyperarousal in patients with PTSD. However, they can worsen other PTSD symptoms and should be avoided.14,30,35 Because of their potential for abuse, dissociative effects, and disinhibiting properties, benzodiazepines have been associated with adverse effects in PTSD.

Antihistamines or hypnotics (e.g., zolpidem [Ambien], zaleplon [Sonata]) may be used for short-term treatment of insomnia in persons with PTSD, and the antidepressant trazodone may be used on a longer-term basis.14,30 There is insufficient evidence to support the use of buspirone (Buspar) as an adjunctive or single agent in the treatment of PTSD.14,30

Mood stabilizers are used to treat mood swings, irritability, impulsivity, and violent behaviors in persons with bipolar disorder, and have been postulated to be effective for the target symptoms of PTSD. However, study results have been mixed.14,29 Thus far, there is only limited support for the adjunctive use of lithium, valproate (Depacon), carbamazepine (Tegretol), lamotrigine (Lamictal), topiramate (Topamax), gabapentin (Neurontin), or second-line agents in the treatment of PTSD, and some guidelines recommend against their use because of their risks and monitoring requirements.14,30,32

Initially, several open-label and controlled studies supported the use of adjunctive atypical antipsychotics in the treatment of severe and refractory PTSD.36 However, a recent large multisite trial of risperidone (Risperdal) reported no benefit over placebo for the treatment of PTSD.37 Consequently, antipsychotics are not recommended.10,14

OTHER ASPECTS OF MANAGEMENT

In addition to the treatments above, other therapies may improve treatment adherence and address certain symptoms adjunctively (e.g., anxiety, chronic pain, sleep disturbance). Acupuncture and yoga have shown promising results, although larger studies are needed.14,38,39 Mobile applications can also be used to manage PTSD symptoms.33

Patients may benefit from a referral to a minister or chaplain to address spiritual needs. Peer-to-peer and family support groups in local communities can augment ongoing treatment. Websites such as the National Center for PTSD (http://www.ptsd.va.gov/public/index.asp), the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury (http://www.dcoe.mil/psychologicalhealth.aspx), and the National Child Traumatic Stress Network (http://www.nctsnet.org) provide useful information for patients and physicians.
