1Post Traumatic Stress Disorder David A. Brady, D.O.Midlothian, Virginia
2AnxietyAnxiety is a normal reaction to stress. It helps us deal with stressful situations, makes us more aware, increases focus and concentration.Anxiety becomes a problem when it becomes an excessive, irrational dread of a situation, event, or object.
3Anxiety DisordersThere are five major types of anxiety disorders. Each has different symptoms but all symptoms cluster around excessive, irrational fear, and dread.Generalized Anxiety DisorderObsessive-Compulsive DisorderPanic DisorderPosttraumatic Stress DisorderSocial Phobia (Social Anxiety Disorder)
4RelevanceLifetime prevalence of PTSD is 1% - 15% in the U.S. population.[In high-risk groups, such as combat veterans and victims of violent crimes, prevalence ranges from 3% to 58%.]
5RelevancePTSD is more prevalent among war veterans than among any other group.The National Vietnam Veterans Readjustment Survey reports that approximately 25% of U.S. veterans, men and women, were suffering from PTSD in the early 1990s.
6Traumatic Events War Mugging Rape Torture Kidnapping Held captive Child abuseAccidents (work related, MVA)Acts of terrorTrain wrecksShip wrecksAir plane crashesBombingsNatural disastersMedical Procedures (Surgeries, ICU / CCU Stays, Chemotherapy, Burn Treatments)
7Posttraumatic Stress Disorder “The complex somatic, cognitive, affective and behavioral effects of psychological trauma.”It is characterized by intrusive thoughts, nightmares and flashbacks of past traumatic events, avoidance of reminders, hypervigilance, and sleep disturbance, which lead to social, occupational and interpersonal dysfunction.
8Posttraumatic Stress Disorder “Neurobiological research has helped us to understand that PTSD is not an “emotional” or “psychological” disorder, but a physiological condition that effects the entire body, including cardiovascular functioning, hormone system balance, and immune functioning.”Hoge
9Posttraumatic Stress Disorder Many people exposed to trauma will experience distress with similar symptoms associated with PTSD.PTSD is a subset of people who are significantly impaired of a period of time greater than 1 month.
10Epidemiology Lifetime prevalence 6.8-12.3 percent Estimated 11 to 17 percent of US veterans returning from active duty in Afghanistan and IraqOnset at any ageFemales > males (4X more likely to develop sx)Susceptibility may run in familiesAssociated with drug and alcohol abuse and/or dependenceLook for one or more of the other anxiety disordersPTSD is associated with increased median annual health care costs (38 to 104%)
11Epidemiology Risk factors Lack of social support = dissociation associated with the traumaExtent of injury is strongly correlated with PTSD (those in combat)Lower socioeconomic statusParental neglectFamily or personal history of psychiatric illnessInitial severity of reaction to traumatic eventPrevious exposure to trauma
12Pathophysiology Unclear pathophysiology MRI studies have shown decreased hippocampal volume in patients with PTSD.Increased central norepinephrine levels with down-regulated central adrenergic receptors, chronically decreased glucocorticoid levels with up regulation of receptors.Hemispheric lateralizationAbnormalities in amygdalaexaggerated response of the amygdala, resulting in impaired regulation by the medial prefrontal cortexpatients with PTSD have diminished activation of the medial prefrontal cortex during the processing of fearInsufficient cognitive resources to engage appropriate cognitive strategies
13Clinical Presentation Marked cognitive, affective, and behavior responses to stimuli, leading to flashbacks, severe anxiety and fleeing or combative behavior.Individuals compensate by avoiding triggers and generally shutting down.Emotional numbing and diminished interest in everyday activities with detachment from others.Sense of a foreshortened futurePsychiatric comorbidity is high:Depression, anxiety, substance abuse, and somatization disorders
14Anger / Irritability“Anger is an emotion, an immediate internal reaction to a situation.”“A problem in our society, and in the approach to anger “management”, is that anger - the emotion - is often confused with other responses.”“It is not the anger that needs managing, but the various behaviors that can arise from it.”Hoge
15FlashbacksFlashbacks consist of images, sounds, smells, or feelings triggered by ordinary events (Examples: car backfires, door slams).
20Symptoms“Every “symptom” included in the definition can also reflect normal responses to life-threatening events or the normal way the body responses to extreme stress.”Hoge
21SymptomsSymptoms are usually worse if the traumatic event was triggered by another person (examples: rape, terror, mugging, direct contact in war).
22Mental Status ExamGeneral appearance may be affected (disheveled / poor personal hygiene).Behavior may be altered. Agitated, extreme startle reaction.Orientation is sometimes affected. The patient may not know the current place or time.Patients may report forgetfulness, especially concerning the specific details of the traumatic event.Concentration is poor.Impulse control is poor.Speech rate and flow may be altered.Mood and affect may be changed. Patients may have feelings of depression, anxiety, guilt, and/or fear.Patients may be more concerned with the content of hallucinations, delusions, suicidal ideation, phobias, and reliving the experience. Certain patients may become homicidal.
23Diagnosis 6 categories: Subjective and objective components of exposure to traumaReexperiencing of the traumaPersistent avoidance of the traumaIncreased arousalDuration > 1 monthDisturbance causes social and vocational impairment…
24DSM IV criteriaThe person has been exposed to a traumatic event in which both of the following have been present: the person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or othersthe person's response involved intense fear, helplessness, or horror. Note: In children, this may be expressed instead by disorganized or agitated behavior.B. The traumatic event is persistently reexperienced in one (or more) of the following ways: recurrent and intrusive distressing recollections of the event, including images, thoughts, or perceptions. Note: In young children, repetitive play may occur in which themes or aspects of the trauma are expressed.recurrent distressing dreams of the event. Note: In children, there may be frightening dreams without recognizable content.acting or feeling as if the traumatic event were recurring (includes a sense of reliving the experience, illusions, hallucinations, and dissociative flashback episodes, including those that occur upon awakening or when intoxicated). Note: In young children, trauma-specific reenactment may occur.intense psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event.physiological reactivity on exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event.
25DSM IV CriteriaC. Persistent avoidance of stimuli associated with the trauma and numbing of general responsiveness (not present before the trauma), as indicated by 3 or more of the following: efforts to avoid thoughts, feelings, or conversations associated with the trauma efforts to avoid activities, places, or people that arouse recollections of the trauma inability to recall an important aspect of the trauma markedly diminished interest or participation in significant activities feeling of detachment or estrangement from others restricted range of affect (e.g., unable to have loving feelings) 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 2 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 responseE. 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.
26Imaging in PTSDMRI studies of the brain suggest that the amount of hippocampal atrophy correlates with the intensity of PTSD symptoms, but MRI is still not a recommended diagnostic test. Some studies in monozygotic twins show that a small hippocampus may be a predisposing factor to the later development of PTSD in the face of a stressor.
27Amygdala hyperactivity combined with hippocampal atrophy seems to be consistent with diagnosis of PTSD.TBI that has destroyed amygdala function will prevent PTSD.

29Differential Diagnosis Acute stress disorderTraumatic Brain InjuryAdjustment disorderMalingering (must be excluded)Mood disorder with or without psychotic featuresPsychotic disorders caused by a general medical conditionSubstance induced disorders
30Implications in Primary Care The diagnosis of PTSD can be missed in a primary care setting, as patients frequently present with somatic complaints or depression and are often reluctant to discuss their traumatic experiences.
32Treatment of PTSDTreatment is often best accomplished with a combination of pharmacologic and nonpharmacologic therapies.Medications may be required to control the physiological symptoms, which can enable the patient to tolerate and work through the highly emotional material in psychotherapy.SSRI’s are first choice in medical managementPrazosin for nightmaresAtypical antipsychoticsIf present, alcohol or substance abuse problems should be the initial focus of treatmentHyperarousal symptoms can be treated with B-blockers
33Treatment of PTSD Exposure Therapy Group Therapy Support Groups Don’t insult the patientNever tell the patient: Don’t talk about your trauma, talk about your feelings…Virtual RealitySexual Issues (psychological and physiological)Physical Issues
34Treatment of PTSDDon’t forget the forgotten (spouses, children, mothers, fathers, brothers, sisters, friends, neighbors, ministers, healthcare providers…)Close medical follow-upExerciseRecreationRoutine (Sleep)Vocational RehabilitationEducationSpiritual Issues
35PrognosisPTSD is a chronic condition with 1/3 of patients recovering at one year and 1/3 symptomatic at 10 years…
36“I hold it to be a fundamental truth of human nature, that when someone withholds something traumatic it can cause great damage. When you share something with someone it helps to place it in perspective, but when you hold it inside, as one of my students once put it, “it eats you alive from the inside out.” Furthermore, there is great therapeutic valve in the catharsis that comes with lancing these emotional boils. The essence of counseling is that pain shared is pain divided…”Grossman
