Epidemiology
• Epidemiological Catchment Area Study (1987)– Lifetime prevalence: 1-2%
• Urban sample of HMO enrollees (1991)– 11.3% of women
• National Comorbidity Study (1995)– 7.8% of responders
![Page 3: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/3.jpg)
Diagnosis
• Exposure of self or others to an “extreme”
stressor (“the trauma”)
– Avoidance
– Re-experiences
– Hyperarousal
![Page 4: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/4.jpg)
Avoidance or Numbing
• Avoidance of associated thoughts, feelings, activities, or places
• Diminished interest
• Detachment
• Restricted range of affect

• The “Great Imposter”
• Management Update
![Page 9: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/9.jpg)

• Exposed to event that involved serious
injury, or a threat to the physical integrity of
self or others
• The person’s response involved intense
fear, helplessness or horror (change from
DSM-IIIR)
![Page 10: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/10.jpg)
Trauma and PTSD in the community,
The 1996 Detroit area survey of trauma
Breslau N, Kessler RC, et. al. Arch Gen Psychiatry, July
1998;55:626-632• A representative sample (2181) persons aged 18-45 years old in the Detroit metropolitan area screened for traumatic events
• 90% of respondents had experienced one or more traumas
• Most prevalent trauma: the unexpected death of a loved one
• Contingent risk for PTSD (all traumas)– women: 13% men: 6.2%
![Page 11: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/11.jpg)

• Personally experienced assaultive violence – 37.7%
• Other personally experience injury or shocking experience – 59.8%
• Learning about traumas to others– 62.4%
• Sudden unexpected death of a loved one – 60.0%
![Page 12: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/12.jpg)

Bullets
• PTSD is a civilian disease
• Non-assaultive trauma is a common and
real stressor in the genesis of PTSD
![Page 14: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/14.jpg)
The “Great Imposter”
• Depression
• Panic attacks
• Substance abuse
• Personality
• Physical symptoms (somatization)
![Page 15: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/15.jpg)
Concurrent Psychiatric Illness in Inpatients with PTSD
• 374 inpatients at a VA Medical Center
• 16.8% have PTSD diagnosis
• Mean number of diagnoses– 1.4 diagnoses non-PTSD– 2.9 diagnoses PTSD
• Alcohol abuse; unipolar depression; atypical psychosis and intermittent explosive disorder
![Page 16: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/16.jpg)
Depression and PTSD
• Significantly associated
• Posttraumatic depression may occur without PTSD
• Depression more likely later in the course of PTSD
• Later in the course the patient may no longer meet criteria for PTSD but may still have major depression
![Page 17: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/17.jpg)
Panic and PTSD
• Panic attack may be a marker for PTSD– Incidence is 69%
• PTSD more common in patients with Major Depression and Panic disorder
• Benzodiazepines are effective in Panic but not in PTSD
![Page 18: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/18.jpg)
Substance Abuse and PTSD
• At least 2 possible courses:– PTSD before the Substance Abuse– PTSD after the Substance Abuse
• Substance Abuse and PTSD likely to be hospitalized more than Substance Abuse alone
• In veterans the incidence of concurrent substance abuse is 60-80%
![Page 19: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/19.jpg)
Personality and PTSD
• PTSD is very common but not universal in
Borderline Personality Disorder
• Early trauma associated
• Repeated or chronic trauma associated
![Page 20: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/20.jpg)
“Complex” PTSD - Herman
• Occurs after prolonged and repeated trauma
• Three broad areas of disturbance– Multiplicity of symptoms
– Characterological changes
– Repetition of harm
![Page 21: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/21.jpg)

Management
• Treatments
– Psychopharmacology
– Psychotherapy
• Setting
– Specialty Mental Health
– Primary Care
![Page 23: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/23.jpg)
Psychopharmacology
• SSRIs (e.g. sertraline)
• Tetracyclics (i.e. trazadone and nafazadone)
• Tricyclics (i.e.imipramine and amitriptyline)
• MAOIs (e.g. phenelzine)
• Benzodiazepines
• Mood stabilizers
• Antipsychotics
![Page 24: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/24.jpg)
Which to choose?
SSRIs are first line treatment
• TCAD: side effects and lethal in suicide
• Benzodiazapines: no RCT showing efficacy and some evidence that PTSD deteriorates with treatment.
• MAOIs: only second line
• Neuroleptics: no RCT to support, the newer novel antipsychotics would be used first and found to have unique clinical application
![Page 25: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/25.jpg)
Medication trail
• 8-12 weeks of SSRI
• If no response then another antidepressant
• If partial response and:– Sleep disturbance then tetracyclic– Irritability then mood stabilizer– Peripsychosis then antipsychotic
![Page 26: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/26.jpg)
Psychotherapies
• Education and supportive
• Cognitive therapy
• Behavioral therapy (relaxation techniques)
• Exposure therapy
• EMDR (eye movement desensitization reprocessing)
![Page 27: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/27.jpg)
Primary Care Setting
• Only 38% of cases receive treatment
• 28% of cases and 75% in treatment are seen in the
primary care setting
– 10% of all PTSD and 25% of those treated are in
the specialty mental health sector
• “did not have a problem requiring treatment” was
the most common reason of the 62% of PTSD
patients not receiving treatment
![Page 28: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/28.jpg)
Management Bullets
• Screen for “worst traumas”
• Suggest and use psychotherapies early
• SSRIs are the first line treatment
• Start low and go slow
• Combine other medications if symptoms persist
![Page 29: New Approaches to Posttraumatic Stress Disorder Robert K. Schneider, MD Assistant Professor Departments of Psychiatry and Internal Medicine The Medical.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649d9f5503460f94a8aa71/html5/thumbnails/29.jpg)
Conclusions
• A civilian disease
• The “trauma” may be non-assaultive
• Often masquerades as another illness
• SSRIs are the treatment of choice
• Combine psychotherapy and medications
• Most PTSD is treated in primary care
