Automatism and post-traumatic stress disorder.

A soldier with post-traumatic stress disorder (PTSD) who committed a criminal act during a dissociative episode is described. This report and other published cases indicate that criminal acts can occur during dissociative episodes among people who suffer from PTSD. However, the evidence suggests that such incidents are rare and may be overemphasised. There often seems to be little relationship between the crimes committed by war veterans and their war experiences.

Stability of recall of military hazards over time. Evidence from the Persian Gulf War of 1991.

BACKGROUND: War time traumatic events are related to subsequent psychological and physical health, but quantifying the association is problematic. Memory changes over time and is influenced by psychological status. AIMS: To use a large, two-stage cohort study of members of the UK armed forces to study changes in recall of both traumatic and 'toxic' hazards. METHOD: A questionnaire-based follow-up study assessed 2370 UK military personnel, repeating earlier questions about exposure to military hazards. RESULTS: The k statistics for reporting of hazards were good for some exposures, but very low for others. Gulf veterans reported more exposures over time (no significant rise in the Bosnia cohort). In the Gulf cohort only, reporting new exposures was associated with worsening health perception, and forgetting previously reported exposures with improved perception. We found no association between physical health, psychological morbidity or post-traumatic stress disorder symptoms and endorsement or non-endorsement of exposures. CONCLUSIONS: Reporting of military hazards after a conflict is not static, and is associated with current self-rated perception of health. Self-report of exposures associated with media publicity needs to be treated with caution.

Quetiapine as an adjunctive treatment for post-traumatic stress disorder: an 8-week open-label study.

This study evaluated the effectiveness of quetiapine for subjects with post-traumatic stress disorder (PTSD) who were already on a stable dose of a selective serotonin reuptake inhibitor (SSRI) but had significant PTSD symptoms. Fifteen subjects were enrolled in an 8-week open-label trial for PTSD in which quetiapine was added to an SSRI. Subjects were on a stable dose of the SSRI for at least 6 weeks before study entry and had a Clincian-Administered PTSD Scale (CAPS) score of greater than or equal to 50 at study baseline. The mean age of subjects was 49 years (eight men and seven women). The average duration of PTSD was 29 years, one-third of subjects had combat-related PTSD, and two-thirds had noncombat PTSD. The mean dose prescribed in the study was 216 mg per day. The initial median CAPS score was 80, indicating severe PTSD. The addition of a modest dose of quetiapine provided significant relief from PTSD symptoms with a 42% overall improvement in PTSD symptoms based on the CAPS and significant improvement along each dimension of symptoms: re-experiencing (Z=-3.24, P=0.0012), hyperarousal (Z=-3.30, P=0.001) and avoidance (Z=-2.13, P=0.03). Subjects rated themselves as 45% improved on average on the Davidson Trauma Scale and reported a 44% decrease in their level of disability and impairment as reflected by the Sheehan Disability Scale. Subjects with PTSD who had significant PTSD symptoms when on an SSRI benefited from the addition of quetiapine. Patients improved significantly on all three clusters of PTSD symptoms: re-experiencing, hyperarousal and avoidance.

Glucocorticoid receptor polymorphisms and post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is reported in some studies to be associated with increased glucocorticoid (GC) sensitivity. Two common glucocorticoid receptor (GR) polymorphisms (N363S and BclI) appear to contribute to the population variance in GC sensitivity. There is some evidence that there may be a genetic predisposition to PTSD. Hence we studied 118 Vietnam war veterans with PTSD for (i) GR polymorphisms, particularly the N363S and the BclI polymorphisms which are thought to be GC sensitising, and (ii) two measures of GC sensitivity, the low-dose 0.25 mg dexamethasone suppression test (LD-DST) and the dermal vasoconstrictor assay (DVVA). The DST and GR polymorphisms were also performed in 42 combat exposed Vietnam war veterans without PTSD. Basal plasma cortisol levels were not significantly different in PTSD (399.5+/-19.2 nmol/L, N=75) and controls (348.6+/-23.0 nmol/L, N=33) and the LD-DST resulted in similar cortisol suppression in both groups (45.6+/-3.2 vs. 40.8+/-4.1%). The cortisol suppression in PTSD patients does not correlate with Clinician Administered PTSD Scores (CAPS), however there was a significant association between the BclI GG genotype and low basal cortisol levels in PTSD (P=0.048). The response to the DVVA was similar to controls (945+/-122, N=106 vs. 730+/-236, N=28, P=0.42). PTSD patients with the GG genotype, however, tended to be more responsive to DVVA and in this group the DVVA correlated with higher CAPS scores. The only exon 2 GR polymorphisms detected were the R23K and N363S. Heterozygosity for the N363S variant in PTSD, at 5.1% was not more prevalent than in other population studies of the N363S polymorphism in Caucasians (6.0-14.8%). The GG genotype of the BclI polymorphism found to be associated with increased GC sensitivity in many studies showed a tendency towards increased response with DVVA and correlated with higher CAPS scores. In conclusion, the N363S and BclI GR polymorphisms were not more frequent in PTSD patients than controls and reported population frequencies. Our PTSD group did not display GC hypersensitivity, as measured by the LD-DST and DVVA. In a subset of PTSD patients with the BclI GG genotype, CAPS scores and basal cortisol levels were negatively correlated.

Gender Differences in service connection for PTSD.

BACKGROUND: Mentally ill female veterans obtain a smaller proportion of their care from Department of Veterans Affairs (VA) facilities than mentally ill male veterans do, possibly because women are less likely than men to be service connected for psychiatric disabilities. "Service connected" veterans have documented, compensative conditions related to or aggravated by military service, and they receive priority for enrollment into the VA healthcare system. OBJECTIVES: To see if there are gender discrepancies in rates of service connection for posttraumatic stress disorder (PTSD) and, if so, to see if these discrepancies could be attributed to appropriate subject characteristics (eg, differences in symptom severity or impairment). RESEARCH DESIGN: Mailed survey linked to administrative data. Claims audits were conducted on 11% of the sample. SUBJECTS: Randomly selected veterans seeking VA disability benefits for PTSD. Women were oversampled to achieve a gender ratio of 1:1. RESULTS: A total of 3337 veterans returned usable surveys (effective response rate, 68%). Men's unadjusted rate of service connection for PTSD was 71%; women's, 52% (P < 0.0001). Adjustment for veterans' PTSD symptom severity or functional impairment did not appreciably reduce this discrepancy, but adjustment for dissimilar rates of combat exposure did. Estimated rates of service connection were 53% for men and 56% for women after adjusting for combat exposure. This combat preference could not be explained by more severe PTSD symptoms or greater functional impairment. CONCLUSIONS: Instead of a gender bias in awards for PTSD service connection, we found evidence of a combat advantage that disproportionately favored men. The appropriateness of this apparent advantage is unclear and needs further investigation.

Lifetime trauma exposure in veterans with military-related posttraumatic stress disorder: association with current symptomatology.

OBJECTIVE: This study examined whether trauma exposure before, during, and/or after military service contributed to current levels of post-traumatic stress disorder (PTSD) and adjustment. Further, we investigated whether trauma exposure before military service was mediated or moderated by military trauma in its effects on current PTSD and adjustment. METHOD: In this retrospective study, archival data from the medical records of 422 male veterans diagnosed with PTSD between December 2001 and July 2004 at a Veterans Administration Medical Center PTSD clinic were analyzed. Measures included the Clinician-Administered PTSD Scale interview as well as self-report measures assessing trauma history, health problems, and general psychopathology (including PTSD). RESULTS: Findings indicated that nonmilitary-related trauma was prevalent in this sample (90%). Regression analyses for PTSD symptom severity revealed that age, greater combat exposure, and a history of physical assault after military service were significantly associated with more severe PTSD symptoms. Childhood physical abuse, adult sexual trauma, and a history of being physically assaulted during military service were also significantly associated with PTSD symptom severity. Mediational analyses indicated that childhood trauma was associated with both adult trauma and increased symptomatology on various outcome measures. Moderational analyses indicated that adult trauma exposure moderated the effect of childhood trauma exposure on health complaints. CONCLUSIONS: Results suggest that several variables, including age, greater combat exposure, and premilitary and postmilitary traumas, are associated with increased PTSD symptomatology. This finding underscores the importance of conducting a thorough assessment of trauma when diagnosing PTSD.

Smaller hippocampal volume predicts pathologic vulnerability to psychological trauma.

In animals, exposure to severe stress can damage the hippocampus. Recent human studies show smaller hippocampal volume in individuals with the stress-related psychiatric condition posttraumatic stress disorder (PTSD). Does this represent the neurotoxic effect of trauma, or is smaller hippocampal volume a pre-existing condition that renders the brain more vulnerable to the development of pathological stress responses? In monozygotic twins discordant for trauma exposure, we found evidence that smaller hippocampi indeed constitute a risk factor for the development of stress-related psychopathology. Disorder severity in PTSD patients who were exposed to trauma was negatively correlated with the hippocampal volume of both the patients and the patients' trauma-unexposed identical co-twin. Furthermore, severe PTSD twin pairs-both the trauma-exposed and unexposed members-had significantly smaller hippocampi than non-PTSD pairs.

Psychiatric casualties of World War II.

AIMS: To observe the natural history of traumatised war veterans. METHODS: A clinical audit of 147 World War II psychiatric war pensioners. RESULTS: Of these veterans only 37% have a clinically sustainable DSM diagnosis of chronic post traumatic stress disorder (PTSD). Trauma-related and somatic symptoms of severity attributable to active war service, were volunteered by 48%. These symptoms were insufficient to fulfil DSM diagnosis criteria for PTSD. CONCLUSIONS: PTSD is a robust clinical entity, yet many victims of trauma appear to suffer chronic sub-syndromal PTSD. The clinical spectrum of trauma response is more variable than is currently diagnostically acceptable by DSM criteria.

Swedish UN soldiers in Cyprus, UNFICYP: their psychological and social situation.

Two Swedish rifle batallions serving as UN soldiers in Cyprus (UNFICYP) have been investigated with respect to their demographic background and motives for application for UN service. The comparison of symptoms of stress in general, of posttraumatic stress disorder specifically, and some other variables of reaction with various studies of Swedish UN soldiers in different settings has given the following results. Very few interviewees experienced 'personal nervous breakdown' (0.5%). The soldiers reported in general very few psychological or psychosomatic complaints in the short time perspective. There seemed, however, to be two groups of persons at risk, namely those who were repatriated and those with a high consumption of alcohol.

Psychiatric morbidity in medical and surgical patients evacuated from the Persian Gulf War.

Acute treatment records of all medical and surgical patients evacuated to Walter Reed Army Medical Center in Washington, D.C., from the Persian Gulf theater (N = 161) were examined to better understand the relationship of injury to psychiatric symptoms. A total of 110 (68 percent) sustained a traumatic injury. They were significantly more likely to have an axis I disorder or psychiatric symptoms of concern than participants in the Persian Gulf War who did not sustain traumatic injuries but who were evacuated for medical conditions. The results indicate that traumatically injured veterans are at greater risk of psychiatric symptoms than veterans who are not injured and that they should be referred for psychiatric evaluation.

Post-traumatic stress disorder and the MMPI-2.

This study compared the MMPI-2 profiles of 27 veterans diagnosed with post-traumatic stress disorder with a non-PTSD comparison group of 27 veteran patients receiving inpatient treatment for other mental disorders. Three multivariate analyses of variance were conducted comparing the two groups on the 10 traditional clinical scales, the 12 supplemental scales and the 15 new content scales on the MMPI-2. The PTSD group obtained a mean profile with peak elevations on the F validity scale and on clinical Scales 2 (D) and 8 (Sc). The multivariate analysis of variance comparing the PTSD and non-PTSD groups across the 10 traditional clinical scales was not significant. The multivariate analyses of variance comparing the two groups on the 12 supplemental scales and the 15 content scales were significant. Significant univariate supplemental scale differences were found on the Keane PTSD scale (PK) and the Post-Traumatic Stress Disorder (PS) scale with the PTSD group scoring higher on PK and PS. Significant univariate content scale differences were found for the Anger (ANG) scale with the PTSD group scoring higher. A cut-off score of 28 on the PK scale correctly classified 76% of the overall sample, 67% of the PTSD group and 85% of the non-PTSD-comparison group.

Treatment preferences of Vietnam veterans with posttraumatic stress disorder.

This study attempted to examine patterns over time in treatment preferences of 65 veterans who completed a 4 month inpatient posttraumatic stress disorders (PTSD) program in order to reveal potentially more beneficial types of treatment. Veterans rated the severity of their symptoms and degree of benefit of 35 different treatment components at discharge, and at 4 and 12 months follow-up. Veterans rated their symptoms as having not changed at discharge, and worsening by 4 months. Veterans initially perceived components that were high in Vietnam content, exploratory in purpose, verbal in modality, and personally focused as most effective, but by 12-month follow-up they perceived these as less effective than components that were low in Vietnam content, educative, action oriented, and externally focused. These effects were strongest among veterans with higher levels of PTSD symptomatology. Combat exposure, childhood abuse, and race were generally not significant predictors of response. These results underscore the importance of further inquiry into the relative value of rehabilitative-oriented and psychotherapeutic-oriented treatments for veterans with severe and chronic PTSD.

Single session effects of treatment components within a specialized inpatient posttraumatic stress disorder program.

This study examined the potential contributions of individual treatment components within one inpatient posttraumatic stress disorders (PTSD) program. Fifteen treatment components were assessed by a self-report instrument administered to a cohort of veterans just before and immediately after each session approximately halfway through the program. Components with an external focus, action modality, and, secondarily, little Vietnam content were associated with more improvement than components with an internal focus, verbal modality, or high Vietnam content. Improvement was greatest in veterans with fewer PTSD symptoms. Short-term improvement was not correlated with veterans' ratings at discharge of component effectiveness. These results were later confirmed on a second cohort. This study supports the potential roles of distraction and physical release, as opposed to exploratory verbal discussion, in the treatment of chronic combat-related PTSD.

Low urinary cortisol excretion in Holocaust survivors with posttraumatic stress disorder.

OBJECTIVE: The authors' objective was to compare the urinary cortisol excretion of Holocaust survivors with posttraumatic stress disorder (PTSD) (N = 22) to that of Holocaust survivors without PTSD (N = 25) and comparison subjects not exposed to the Holocaust (N = 15). METHOD: Twenty-four-hour urine samples were collected, and the following day, subjects were evaluated for the presence and severity of past and current PTSD and other psychiatric conditions. RESULTS: Holocaust survivors with PTSD showed significantly lower mean 24-hour urinary cortisol excretion than the two groups of subjects without PTSD. Multiple correlation analysis revealed a significant relationship between cortisol levels and severity of PTSD that was due to a substantial association with scores on the avoidance subscale. CONCLUSIONS: The present findings replicate the authors' previous observation of low urinary cortisol excretion in combat veterans with PTSD and extend these findings to a non-treatment-seeking civilian group. The results also demonstrate that low cortisol levels are associated with PTSD symptoms of a clinically significant nature, rather than occurring as a result of exposure to trauma per se, and that low cortisol levels may persist for decades following exposure to trauma among individuals with chronic PTSD.

Long-term effects of trauma: post-traumatic stress among civilian internees of the Japanese during World War II.

This study examined predictors and health-related effects of post-traumatic stress among 129 civilian internees of the Japanese during World War II. Post-traumatic stress disorder was noted in 36.7% within the 6 months after their release and in 15.0% within the most recent 6 months. Women were more likely than men to indicate post-traumatic stress disorder within the 6 months after their release. Higher incomes were associated with lower levels of post-traumatic stress within the most recent 6 months. After controlling for demographic and internment-related factors, higher levels of post-traumatic stress were associated with poorer physical health. This association was stronger among older internees than among their younger counterparts. Implications of the findings for clinical gerontology are discussed.

Delusional psychoses associated with unpatriotic conduct during World War II: a long-term follow-up study.

Of a large sample of patients with paranoid psychoses consecutively admitted to the Psychiatric Department, University of Oslo, during a period after World War II, 10 patients (6.3%, 9 women and 1 man) became ill through accusations of unpatriotic conduct during the war. The psychosis seemed precipitated in connection with legal procedures against the patient in 3 cases, and against close relatives in 2 patients. In 2 cases mixed precipitating events were present, while the psychosis in 3 cases had a connection with the woman being intimate with occupation soldiers. Discharge diagnosis according to DSM-III was schizophrenia (n = 2), schizophreniform disorder (n = 4), schizoaffective disorder (n = 1), major depressive disorder (n = 1), mania (n = 1), and atypical psychosis (n = 1). The patients have been followed up twice, with a mean 31 years of observation. Course and outcome varied, mostly according to the diagnosis. Most patients had a favorable global outcome, although they had a tendency to keep up their social isolation. None of the patients felt they had done anything wrong or regretted their behavior during the war.

Change of diagnosis of post-traumatic stress disorder related to compensation-seeking.

AIM: To explore the change in the diagnosis of posttraumatic stress disorder (PTSD) related to the implementation of the new national regulation on compensation-seeking by war veterans in Croatia. METHODS: The study included 225 compensation-seeking war veterans who were psychiatrically assessed and diagnosed on three different occasions. The first diagnosis was made by a local psychiatrist when a veteran sought psychiatric help for the first time. The second psychiatric diagnosis was established during the veteran's psychiatric treatment, and the third one was made by an independent expert team in charge of the psychiatric assessment for compensation purposes. The expert examination included structured diagnostic procedure and analysis of military service data. The diagnoses established on three different points were compared. RESULTS: There were significant differences between the diagnoses of mental disorders made at three different occasions in compensation-seeking war veterans. Six different diagnostic categories of mental disorders were confirmed. The diagnosis changed in 134 (59.5%) out of 225 veterans, mainly in the categories of PTSD and personality changes due to catastrophic experience, during their psychiatric treatment in the 2000-2002 period, when the new regulation for compensation was implemented. PTSD diagnosis remained unchanged at all three psychiatric assessments in only 7.5% of the veterans, whereas the diagnosis of a mental disorder remained unchanged in 37 (16.4%) veterans. Experts' confirmation of PTSD or PTSD comorbid with other mental disorders positively correlated with the number of hospitalizations. CONCLUSION: Inconsistencies in the diagnosis of PTSD could be related to the different diagnostic criteria and the course of illness. Psychiatric examination for compensation purposes should be independent and integrate all relevant data for making a complete assessment. Compensation-seeking policy, represented by new regulations, could be a source of bias in diagnostic outcome.

Anniversary reactions in Gulf War veterans: a naturalistic inquiry 2 years after the Gulf War.

The goal of this study was to assess the occurrence of anniversary reactions in Gulf War veterans 2 years after the conclusion of Operation Desert Storm. Subjects were administered questionnaires and asked to identify specific months of best and worst functioning, and months of least or most symptoms of posttraumatic stress disorder (PTSD). Negatively experienced months were compared to documented dates of exposure to traumatic events during the war. Anniversary reactions occurred with a frequency greater than chance and were seen most in individuals exposed to a greater number, and to more severe types, of traumatic events. This suggests that anniversary reactions are etiologically linked to traumatic events and may be a part of the syndrome of PTSD.
