The treatment of post-traumatic stress disorder.

This report reviews treatment studies of post-traumatic stress disorder (PTSD). Much of the literature is descriptive and concentrates on particular treatment modalities without attempting to integrate these different approaches into the wider body of knowledge about PTSD. No study has randomly assigned patients to experimental and control groups. The treatment of 56 patients with PTSD is described, highlighting issues which influence the choice of approach and focus of therapy. These issues are seldom mentioned in the PTSD literature and include the unusual difficulties involved in developing a therapeutic alliance, the role of non-specific elements and the treatment of coexistent psychiatric disorders which are frequently present. The need to consider separately the degree of disturbed attention and arousal, the nature of the traumatic preoccupation and the patient's social and occupational functioning are stressed. The lack of knowledge about the natural history of PTSD and the different effectiveness of treatments in the acute and chronic stages are other uncertainties about the treatment of PTSD. Consideration of these points has led to a series of recommendations for future studies of the treatment of PTSD.

Issues and controversies in the understanding and diagnosis of compassion fatigue, vicarious traumatization, and secondary traumatic stress disorder.

Understanding the effects of prolonged contact, in a professional role, with trauma victims has led to conceptualizations of helper stress. Various terms such as compassion fatigue, vicarious traumatization, secondary traumatic stress reactions, empathic strains, burn out, and Type land Type II countertransference have been proposed These terms required conceptual classification to make a proper diagnosis and classification of their impact on the helping process. It is proposed that Traumatoid States is a more inclusive and accurate term to define sub-types of occupationally-related stress response syndromes (OSRS).

Open trial of citalopram in adults with post-traumatic stress disorder.

The selective serotonin reuptake inhibitors (SSRIs) are rapidly emerging as preferred first-line drugs in the pharmacological management of post-traumatic stress disorder (PTSD). Citalopram, an SSRI with highly potent and selective serotonin reuptake inhibition, may be a useful agent for treating the intrusive, avoidance, and arousal symptoms that characterize PTSD. Fourteen adult subjects (12 with civilian-related post-traumatic stress disorder, and 2 with combat-related post-traumatic stress disorder) were entered into an 8 wk, open- label, fixed-dose trial of citalopram, commencing with 20 mg/d, and increasing to 40 mg/d after 2 wk. Eleven subjects completed 8 wk treatment and were included in the data analysis. Based on the Clinician-Administered Post-traumatic Stress Disorder Scale (CAPS-2), there was significant reduction in all core PTSD symptoms (re-experiencing, hyperarousal, and avoidance) by week 8. Nine of the 11 completers were classified as 'responders' on Clinical Global Impression Improvement scores. Secondary measures of depression (Montgomery-Asberg Depression Rating Scale) and anxiety (Hamilton Anxiety Scale) also improved significantly by week 8. Citalopram was tolerated well, and there were no dropouts due to adverse effects. Data from this preliminary open trial suggests that citalopram, an SSRI, may be effective for reducing the key symptoms of PTSD, however, these findings need confirmation in double-blind, placebo-controlled trials.

Resilience-recovery factors in post-traumatic stress disorder among female and male Vietnam veterans: hardiness, postwar social support, and additional stressful life events.

Structural equation modeling procedures were used to examine relationships among several war zone stressor dimensions, resilience-recovery factors, and post-traumatic stress disorder symptoms in a national sample of 1,632 Vietnam veterans (26% women and 74% men). A 9-factor measurement model was specified on a mixed-gender subsample of the data and then replicated on separate subsamples of female and male veterans. For both genders, the structural models supported strong mediation effects for the intrapersonal resource characteristic of hardiness, postwar structural and functional social support, and additional negative life events in the postwar period. Support for moderator effects or buffering in terms of interactions between war zone stressor level and resilience-recovery factors was minimal.

Sleep in post-traumatic stress disorder and panic: convergence and divergence.

Disturbed sleep is a common clinical problem in anxiety disorders, particularly in patients with post-traumatic stress disorder (PTSD) and panic disorder (PD). Several studies have attempted to validate the subjective sleep complaints of these disorders using laboratory polysomnography. These attempts, typically focusing on PTSD or PD independently, have demonstrated inconsistent results. To our knowledge, no such studies have attempted to directly compare and contrast sleep disturbances in PTSD and PD together. Our review of the studies of subjective sleep disturbances, sleep architecture, and sleep-related biologic phenomena suggests that a comparative characterization of sleep disturbances in these two disorders is timely. Such an inference is based on our identification of several areas of convergence and divergence between PTSD and PD found in the published literature, as well as our own preliminary investigations. Specifically, PTSD and PD seem to converge on several sleep-related parameters, namely, sleep quality, presence of episodic parasomnias, and movement time. They also appear to diverge in other important sleep-related areas such as respiratory disturbances and the particular phenomenological nature of episodic parasomnias, namely nightmares or nocturnal panic attacks. Investigations focusing on such overlapping phenomena may provide groundwork for further elucidation of central fear systems underlying these two disorders. Additionally, such sleep studies have the potential to provide important insights into ongoing efforts to develop a cohesive conceptual framework into the patho-physiologies of these disorders.

Estimating post-traumatic stress disorder in the community: lifetime perspective and the impact of typical traumatic events.

BACKGROUND: Community surveys have assessed post-traumatic stress disorder (PTSD) in relation to traumatic events designated by respondents as the worst they have ever experienced. An assessment of PTSD in relation to all reported traumas would impose too great a burden on respondents, a considerable proportion of whom report multiple traumas. The 'worst event' method is efficient for identifying persons with PTSD, but may overestimate the conditional probability of PTSD associated with the entire range of PTSD-level traumas. In this report, we evaluate this potential bias. METHOD: The Detroit Area Survey of Trauma (n = 2181) estimated the PTSD risk from two samples of traumas: (1) a representative sample of traumas formed by selecting a random trauma from each respondent's list of traumas; and (2) traumas designated by respondents as the worst (the standard method). RESULTS: Both estimation methods converged on key findings, including identifying trauma types with the highest probability of PTSD and sex differences in the risk of PTSD. Compared to the random events, the 'worst event' method yielded a moderately higher conditional probability for PTSD (0.136 v. 0.092). The bias was due almost entirely to the deviation of the distribution of the worst events from expected values, if all event types had equal prior selection probabilities. Direct adjustment, setting the distribution equal to expected values and applying the observed probabilities of PTSD associated with individual event types brought the estimate close to the unbiased estimate, based on the randomly selected traumas. CONCLUSIONS: Only the 'worst event' method can be used as a short-cut to assessing all traumas. The bias in the estimated risk of PTSD is modest and is attenuated by direct adjustment.

Neutrophil beta2-adrenergic receptor coupling efficiency to Gs protein in subjects with post-traumatic stress disorder and normal controls.

The symptomatology of post-traumatic stress disorder (PTSD) involves sympathetic hyperarousal. Several of these sympathetic symptoms are mediated through end-organ beta2-adrenergic receptors (beta2AR). Increased sympathetic activity in PTSD could therefore be due to increased betaAR function. This study investigated betaAR function in 30 healthy controls and 20 drug-free PTSD patients. BetaAR binding studies were conducted using antagonist-saturation and agonist-displacement experiments. Measures of beta2AR coupling to Gs protein were derived from agonist-displacement experiments. PTSD patients had significantly higher beta2AR density particularly in the high-conformational state and higher beta2AR coupling than controls, as reflected in a higher percentage of receptors in the high conformational state and a higher ratio of the agonist dissociaton constant from the receptor in the low/high-conformational state. Increased betaAR function in PTSD is consistent with the symptomatology of this disorder. Increased betaAR density and coupling may be consistent with downregulation of betaAR density and uncoupling by antidepressants and may underlie their partial efficacy in PTSD. Dysregulation in Gs protein function is postulated and, agonist-mediated regulation of betaAR expression and/or betaAR kinase activity in PTSD should be investigated in future studies.

Post-traumatic stress disorder in the community: an epidemiological study.

Post-traumatic stress disorder (PTSD) was studied in the Piedmont region of North Carolina. Among 2985 subjects, the lifetime and six month prevalence figures for PTSD were 1.30 and 0.44% respectively. In comparison to non-PTSD subjects, those with PTSD had significantly greater job instability, family history of psychiatric illness, parental poverty, child abuse, and separation or divorce of parents prior to age 10. PTSD was associated with greater psychiatric comorbidity and attempted suicide, increased frequency of bronchial asthma, hypertension, peptic ulcer and with impaired social support. Differences were noted between chronic and acute PTSD on a number of measures, with chronic PTSD being accompanied by more frequent social phobia, reduced social support and greater avoidance symptoms.

Myocardial infarction and post-traumatic stress disorder: frequency, outcome, and atherosclerotic mechanisms.

BACKGROUND: Post-traumatic stress disorder (PTSD) may develop in the aftermath of an acute myocardial infarction (MI). Whether PTSD is a risk factor for cardiovascular disease (CVD) is elusive. The biological mechanisms linking PTSD with atherosclerosis are unclear. DESIGN: A critical review of 31 studies in the English language pursuing three aims: (i) to estimate the prevalence of PTSD in post-MI patients; (ii) to investigate the association of PTSD with cardiovascular endpoints; and (iii) to search for low-grade systemic inflammatory changes in PTSD pertinent to atherosclerosis. METHODS: We located studies by PubMed electronic library search and through checking the bibliographies of these sources. RESULTS: The weighted prevalence of PTSD after MI was 14.7% (range 0-25%; a total of 13 studies and 827 post-MI patients). Two studies reported a prospective association between PTSD and an increased risk of cardiovascular readmission in post-MI patients and of cardiovascular mortality in combat veterans, respectively. In a total of 11 studies, patients with PTSD had increased rates of physician-rated and self-reported cardiovascular diseases. Various cytokines and C-reactive protein were investigated in a total of seven studies suggesting that PTSD confers a pro-inflammatory state. CONCLUSIONS: Increasing evidence suggests that PTSD specifically related to MI develops considerably frequently in post-MI patients. More research is needed in larger cohorts applying a population design to substantiate findings suggesting PTSD is an atherogenic risk factor and to understand better the suspected behavioural and biological mechanisms involved.

Sexual violence, post-traumatic stress disorder and dementia.

Little is known of Post-Traumatic Stress Disorder (PTSD) in older people. No literature exists on this disorder in older women exposed to sexual assault. A case of apparent PTSD in a demented woman raises questions of the anatomy and phenomenology of this disorder. Difficulties in diagnosis in a demented population may cloud the issues or prevent a proper therapeutic outcome.

Lifetime sexual and physical victimization among male veterans with combat-related post-traumatic stress disorder.

Because of the high prevalence of post-traumatic stress disorder (PTSD) among veteran men and the limited research on victimization in this group, we recruited 133 male veterans with combat-related PTSD from a psychiatric inpatient unit and assessed them for lifetime physical and sexual trauma. Results indicated that 96% of the sample had experienced some form of victimization over their lifetimes; 60% reported childhood physical abuse, 41% childhood sexual abuse, 93% adulthood physical assault, and 20% adulthood sexual assault. In the preceding year alone, 46% experienced either physical or sexual assault. These findings support the need for routine inquiry into the histories of noncombat victimization in this cohort. Determining the lifetime history of trauma exposure may have implications for vulnerability to subsequent development of PTSD and the risk of future violence.

The Trauma Symptom Inventory: factors associated with invalid profiles in a sample of combat veterans with post-traumatic stress disorder.

The assessment of combat-related post-traumatic stress disorder (PTSD) relies upon self-reported symptoms and the need for indicators of valid reporting is critical. The Trauma Symptom Inventory (TSI) is a testing instrument specific to PTSD which includes validity scales. In a pilot study examining the use of the TSI with combat veterans, 50 male veterans diagnosed with PTSD were administered the TSI. Nineteen percent of the profiles were invalid, all but one based on the Atypical Response Scale. Differences between veterans with valid and invalid TSI profiles are examined in terms of demographic and historical factors, TSI profiles, and individual scale items. The model best able to predict invalid profiles included high scores on subscales measuring dissociative experiences and tension reduction behaviors. Implications for the interpretation of TSI validity scales in assessing combat-related PTSD are discussed.

Assessment of post-traumatic stress disorder and comorbidity.

The symptoms of lifetime post-traumatic stress disorder (PTSD) and comorbid diagnoses were compared among 502 combat-experienced soldiers under examination for compensation-related purposes to confirm or deny the diagnosis of PTSD and 196 soldiers with combat experience without any psychiatric disorder. The two groups were matched with regard to duration of combat experience, time between combat experience and the study, age, marital status, and education. PTSD was diagnosed by psychiatrists with a structured clinical interview according to the research version of the International Classification of Diseases and the Diagnostic and Statistical Manual of Mental Disorders. The psychologists applied the Mississippi Scale for Combat-Related PTSD, Watson's criteria for PTSD, the Minnesota Multiphasic Personality Inventory version 201, and the Trauma Questionnaire. Also, a very detailed heteroanemnestic questionnaire was completed by social workers. Medical documentation and data from the combat services were provided during the examination for compensation-related purposes. After psychiatric and psychological assessment, 20% of the combat-experienced soldiers under examination for compensation-related purposes were diagnosed with lifetime PTSD, 47% were diagnosed with PTSD and comorbid disorders, 6% were diagnosed with PTSD and enduring personality change, and 5% were diagnosed with adjustment disorder. Twelve percent did not fulfill any diagnostic psychiatric criteria, and 10% fulfilled diagnostic criteria for other psychiatric disorders, although they had previous medical documentation confirming PTSD diagnoses. Correlation coefficients between psychiatric and psychological assessment were significant, indicating their complementarity in reaching the final diagnosis. It is necessary to include many different assessment methods in the examination for forensic or compensation-related purposes to obtain a more objective assessment.

Evaluation of the hippocampus and the anterior cingulate gyrus by proton MR spectroscopy in patients with post-traumatic stress disorder.

PURPOSE: Previous studies have shown that post-traumatic stress disorder (PTSD) is associated with lymbic system dysfunction. The purpose of this study is to evaluate whether or not the neuronal integrity in hippocampus and anterior cingulate gyrus is affected in PTSD as assessed by proton magnetic resonance spectroscopy. MATERIALS AND METHODS: Single voxel MRS was performed in 10 PTSD patients and 6 healthy subjects in two cerebral areas highly involved in the pathophysiology of PTSD (the hippocampus and the anterior cingulate gyrus). Spectra were obtained using PRESS sequence. Voxel sizes were 3.7 cm3 (hippocampus) and 6-7.2 cm3 (anterior cingulate gyrus). Metabolite ratios of NAA/Cr and Cho/Cr were calculated and compared to the control subjects. The severity of PTSD in the patient group was evaluated by Clinician-Administered PTSD Scale. RESULTS: Analysis of the proton MR spectra showed reductions in NAA/Cr ratio in bilateral hippocampus of PTSD subjects as compared to normal controls (p < 0.001), whereas Cho/Cr ratios were increased (p < 0.001). Reductions in NAA/Cr ratio were found in the the anterior cingulate gyrus of PTSD subjects as compared to normal controls (p < 0.01), whereas Cho/Cr ratios did not differ significantly (p > 0.05). CONCLUSION: Changes in the metabolite ratios provide support for either neuronal dysfunction or neuronal loss both in the hippocampus and the anterior cingulate gyrus and may be associated with reduced neuronal integrity. Further studies with MRS in larger patient populations are needed to clarify the relationship between brain structures and neurobiology of PTSD.

Post-traumatic stress disorder and GI endoscopy: a case study.

Post-traumatic stress disorder (PTSD) can be caused by experiencing or witnessing a variety of harsh traumatic events. Rape, burglary, war, torture, violence, and other catastrophic events have been known to precipitate flashbacks, nightmares, and inability to cope with the demands of daily life. The symptoms associated with PTSD can interfere with work, sleep, appetite, relationships, and health. In a Veterans Administration hospital population, PTSD is not an uncommon patient problem: it usually results from witnessing and/or participating in war or military service-related circumstances. This case study describes a 42-year-old man who was a prisoner of war in Vietnam. The form of torture his Vietnamese captors subjected him to presented a challenging situation when he required an endoscopic examination of the upper gastrointestinal tract. The purpose of this case study is to offer suggestions to the GI and endoscopy nursing staff who care for these patients, and to make GI health care providers aware of the special needs of this patient population.

Post-traumatic stress disorder in pre-school aged children after a gas explosion.

UNLABELLED: To evaluate the sensitivity of diagnostic criteria for post-traumatic stress disorder (PTSD) in pre-school aged children involved in a gas explosion, post-traumatic symptoms of the children were investigated four times after the accident, immediately, 10 days, 6 months, and 1 year later. Using symptoms at 6 months after the accident, sensitivity of diagnostic criteria was assessed by comparing the fourth edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and the alternative criteria for infants and young children [10]. In addition, the published Child Post-Traumatic Stress Disorder Reaction Index (CPTSD-RI) and its modified version proposed by us were also evaluated their sensitivity to rate the symptoms. Girls had a tendency to show more post-traumatic symptoms than boys. Although no children met DMS-IV criteria for PTSD, 8 children out of 32 were diagnosed as having PTSD with alternative criteria. With our modified CPTSD-RI, all eight children were decidedly more statistically distinguishable from those without PTSD than with original index. CONCLUSION: our data indicate that the sensitivity of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (4th edition) and the Child Post-Traumatic Stress Disorder Reaction Index in rating symptoms of pre-school aged children is not sufficient. The alternative criteria of the former and modified version of the latter would be the better choice in this age group.
