I. Introduction

Exposure to a traumatic event is normally accompanied by distress. For most individuals such distress resolves spontaneously without the onset of any psychiatric illness. Among a subset of people, the type, severity, and duration of symptoms that develop following trauma will meet criteria for either acute stress disorder (ASD) or post-traumatic stress disorder (PTSD).

ASD is not as well studied as PTSD. Some trauma researchers feel ASD is on a continuum with PTSD and that the cut-off times for the two disorders are arbitrary. Therefore, a more detailed description of trauma and its treatment is provided in Section II: Post-Traumatic Stress Disorder.

Trauma can affect both psychological and physical functioning. Some research has suggested that the physical effects of trauma have been related to significant health problems, such as diminished functioning of the immune system and increased susceptibility to infections. The psychological effects of PTSD may manifest in increased risk-taking behavior, such as substance use, poor eating habits, or unsafe sexual activity. In addition, patients with PTSD may suffer from depression, social isolation, impairments in trust and attachments, and feelings of anger. Patients with HIV/AIDS may be affected by past trauma to the point that it manifests in problems with disease management, such as disrupted or negative interactions with medical personnel and/or medication non-adherence.


Key Point

Exposure to traumatic events can lead to increased risk-taking behavior, including substance use, unsafe sexual practices, and difficulty forming therapeutic relationships with medical personnel.


II. Post-Traumatic Stress Disorder (PTSD)

PTSD can result from a single traumatic event, such as a car accident, rape, or experience of a natural disaster, or from an ongoing pattern of traumatic experiences, such as childhood abuse (physical and/or sexual), domestic violence, homelessness, military duty or combat, or severe chronic illness. Because the psychological symptoms that commonly occur following a traumatic event may remit spontaneously over time for most people, some researchers conceptualize PTSD as a disorder of recovery.


Key Point

The likelihood of a patient developing PTSD varies according to the vulnerability of the affected person and the severity of the stressor.


A history of previous traumatic experiences increases a person's vulnerability to developing PTSD upon exposure to subsequent trauma. Previous traumatic experiences may impair his/her ability to handle future stressors. The more severe the trauma is, the greater the likelihood will be that the patient will develop PTSD.

The rate of PTSD following exposure to a particular trauma ranges from 12% to 70%, with the higher rates occurring in populations exposed to traumas that involve interpersonal violence (e.g., rape, sexual abuse, torture). Women have higher rates of PTSD than men. Among women, sexual assault is the most common precipitating trauma, whereas among men, the most common trauma is combat exposure.

Although PTSD has a lifetime prevalence rate of approximately 1.3% to 7.8% in the general population, the rates of PTSD in the HIV-infected population are higher. The prevalence of PTSD in HIV-infected individuals may be as high as 42%.1 Although onset of a severe, life-threatening illness (such as HIV/AIDS) can sometimes in itself be a traumatic experience leading to PTSD, more often a history of physical or psychological trauma (and diagnosis of PTSD) co-occurs with an individual's HIV status. Among people with the most severe mental illnesses, specifically schizophrenia, schizoaffective disorder, and bipolar disorder, comorbid PTSD is an important predictor of HIV infection.2


A. Presentation

Patients with PTSD may show a variety of symptoms, which must persist for more than 1 month to meet the criteria for PTSD. The symptoms may be straightforward or may vacillate between overwhelming emotions caused by memories of the event and emotional numbness and dissociation. Dissociation is a disruption in the ordinary integration of consciousness, memory, or identity. It can present as flashbacks, depersonalization, derealization, and/or episodes of lost time.


B. Diagnosis

Recommendations:

The primary care clinician should screen for PTSD annually or more often as clinically indicated.

Clinicians should use the criteria listed in the DSM-IV for a diagnosis of PTSD in patients with HIV/AIDS (see Table 1).

Clinicians should screen patients with PTSD or significant trauma histories for clinical depression, anxiety disorders, or alcohol or other substance use disorders.


Key Point

Patients with PTSD may have dissociative symptoms, which may be mistaken for HIV-related dementia or other HIV-related neuropsychiatric disorders.


In patients with a history of traumatic experience, it is important to assess for the presence of PTSD by asking about the experience of the trauma and reviewing the symptoms. PTSD is diagnosed when symptoms have been present for more than 1 month and an individual meets the other criteria listed in Table 1.


Table 1: Diagnostic Criteria for Post-Traumatic Stress Disorder

A. The person has been exposed to a traumatic event in which both of the following were present:

  1. The person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death, serious injury, or a threat to the physical integrity of self or others
  2. The person's response involved intense fear, helplessness, or horror

B. The traumatic event is persistently re-experienced in one (or more) of the following ways:

  1. Recurrent and intrusive distressing recollections of the event, including images, thoughts, or perceptions
  2. Recurrent distressing dreams of the event
  3. Acting or feeling as if the traumatic event were recurring (e.g., a sense of reliving the experience, illusions, hallucinations, and dissociative flashback episodes, including those that occur upon awakening or when intoxicated)
  4. Intense psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event
  5. Physiological reactivity upon exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event

C. Persistent avoidance of stimuli associated with the trauma and numbing of general responsiveness (not present before the trauma) as indicated by three (or more) of the following:

  1. Efforts to avoid thoughts, feelings, or conversations associated with the trauma
  2. Efforts to avoid activities, places, or people that arouse recollections of the trauma
  3. Inability to recall an important aspect of the trauma
  4. Markedly diminished interest or participation in significant activities
  5. Feeling of detachment or estrangement from others
  6. Restricted range of affect (e.g., unable to have loving feelings)
  7. Sense of a foreshortened future (e.g., does not expect to have a career, marriage, children, or a normal life span)

D. Persistent symptoms of increased arousal (not present before the trauma) as indicated by two (or more) of the following:

  1. Difficulty falling or staying asleep
  2. Irritability or outbursts of anger
  3. Difficulty concentrating
  4. Hypervigilance
  5. Exaggerated startle response

E. Duration of the disturbance (symptoms in criteria B, C, and D) is more than 1 month

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

C. Management of Survivors of Trauma

Recommendations:

Clinicians should refer patients with symptoms of PTSD to a mental health professional as soon as possible for evaluation for psychotherapy or other forms of psychiatric treatment. The goal of treatment should be to reduce symptoms and fully reintegrate a safe sense of self.

If specialized services are unavailable, the primary care clinician should prescribe medications (see Appendix II) and monitor the degree of improvement achieved with this strategy alone.

During the acute phase of treatment, clinicians should assess the patient's risk for harm to him/herself or others.

Some patients respond to medication and brief supportive interventions; most require psychotherapy and specialized mental health intervention. However, if such services are not available, the primary care clinician should prescribe medication and monitor the degree of improvement achieved with this strategy alone.

There is no single medication that treats all of the symptoms of PTSD. Currently, sertraline and paroxetine are the only FDA-approved medications for PTSD. Paroxetine should be avoided in patients less than 18 years old because of its possible association with increased suicide risk. All SSRIs (in the same doses used for depression) are helpful in treating symptoms of depression and anxiety. Moreover, controlled and open studies of various SSRIs as well as other classes of antidepressants have shown benefit in treating PTSD symptoms.3 Open trial studies of mood stabilizers have also shown some benefits. Long-term benzodiazepine use is not a preferred treatment. If benzodiazepines are prescribed, careful monitoring is required due to the potential for abuse and concerns about disinhibition in those with significant dissociative symptoms.


Key Point

Although patients with PTSD may seek help for associated somatic symptoms, they may perceive medical intervention as intrusive and thus re-traumatizing.


Empirically validated psychotherapy treatments include exposure therapy, anxiety management programs, and cognitive therapy. These treatments modify fear and false cognitions created in response to single or multiple traumas and improve coping skills in the face of new stressors. Treatment is offered through individual and group modalities. Several studies show that psychodynamic treatments can also be helpful. Early evidence supports concurrent treatment of PTSD and addiction.
