Selected AbstractsMemory and prefrontal functions in earthquake survivors: differences between current and past post-traumatic stress disorder patientsACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2009E. Eren-Koçak Objective:, Many studies reported deficits in cognitive functions in post-traumatic stress disorder (PTSD). Most were, however, conducted on man-made trauma survivors. The high comorbidity of alcohol use and depression with PTSD in these studies further complicated the interpretation of their results. We compared prefrontal lobe functions and memory in three earthquake survivor groups: current PTSD, past PTSD and no PTSD. We hypothesized that prefrontal performances of the current and past PTSD groups would be worse than that of control group. Method:, Survivors of the 1999 earthquakes in Turkey were evaluated for current and lifetime PTSD. Memory and prefrontal functions were assessed by a neuropsychological test battery. Results:, Current PTSD patients performed worse on attention, verbal memory, verbal fluency, and psychomotor speed. Past PTSD group was similar to the controls on most cognitive measures, except for their vulnerability to proactive interference and low performance in verbal fluency for animal names. Conclusion:, Our findings indicate that the prefrontal organization and monitorization of verbally processed information are defective in earthquake-related PTSD patients, more so in the current PTSD group. [source] Short-term treatment of post-traumatic stress disorder with naltrexone: an open-label preliminary studyHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2002Gad Lubin Abstract Eight patients (6 men and 2 women) with chronic post-traumatic stress disorder (PTSD) were treated with naltrexone 100,200,mg/day. Seven patients completed 2 weeks of treatment. A subtle and clinically insignificant improvement was noted in intrusive and hyperarousal symptoms (p,<,0.05 for both), but not in avoidance symptoms. All patients demonstrated side effects which limited the targeted dose. It is suggested that the subtle positive effect of naltrexone and the hypersensitivity of these patients to its side effects do not encourage the use of naltrexone in the treatment of PTSD patients.

[source] Effects of three PTSD treatments on anger and guilt: Exposure therapy, eye movement desensitization and reprocessing, and relaxation training,JOURNAL OF TRAUMATIC STRESS, Issue 1 2006Jennifer A. Stapleton This study sought to investigate the efficacy of prolonged exposure, eye movement desensitization and reprocessing, and relaxation training on trait anger and guilt and on trauma-related anger and guilt within the context of posttraumatic stress disorder (PTSD) treatment. Fifteen PTSD patients completed each treatment and were assessed at posttreatment and at 3-month follow-up. All three treatments were associated with significant reductions in all measures of anger and guilt, with gains maintained at follow-up. There were no significant treatment differences in efficacy or in the proportion of patients who worsened on anger or guilt measures over the course of treatment. Between-treatment effect sizes were generally very small. Results suggest that all three treatments are associated with reductions in anger and guilt, even for patients who initially have high levels of these emotions. However, these PTSD therapies may not be sufficient for treating anger and guilt; additional interventions may be required. [source] Effects of Brief Eclectic Psychotherapy in patients with posttraumatic stress disorder: Randomized clinical trialJOURNAL OF TRAUMATIC STRESS, Issue 3 2005Ramón J.L. Lindauer Brief Eclectic Psychotherapy (BEP) is a manualized psychotherapy for posttraumatic stress disorder (PTSD) which has proven effective for police officers. This article reports on a randomized clinical trial using BEP to treat other types of PTSD patients recruited from an outpatient clinic. Twenty-four patients were randomly assigned to a treatment or a waitlist group. Assessment of PTSD was made before and after the treatment period (4 months). No significant differences between the groups were observed at pretest. By posttest, BEP had effectively reduced PTSD as well as general anxiety symptoms in the treated group of outpatients as compared to the waitlist group. [source] Fear activation and habituation patterns as early process predictors of response to prolonged exposure treatment in PTSDJOURNAL OF TRAUMATIC STRESS, Issue 5 2002Agnes van Minnen Abstract Improved (n = 21) and nonimproved (n = 13) PTSD patients (a mixed trauma population) were compared for fear activation and habituation patterns during and between the 1st and 2nd prolonged exposure sessions. Drop-outs (n = 11) were also evaluated. Nonimproved patients had significantly higher ratings of anxiety at the start of the first exposure session. Improved patients showed more within-session habituation during the self-exposures at home and more between-session habituation. Even after controlling for initial PTSD and depression symptom severity, habituation between the first and second exposure sessions was significantly related to treatment outcome. Patients who dropped out of the treatment were found not to differ from completers on fear activation and within-session habituation during the first exposure session. [source] Polysomnography in patients with post-traumatic stress disorderPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2010Sinan Yetkin MD Aims:, The purpose of the present study was to investigate sleep structure in post-traumatic stress disorder (PTSD) patients with and without any psychiatric comorbidities. The relationship between sleep variables and measurements of clinical symptom severity were also investigated. Methods:, Sleep patterns of 24 non-medicated male PTSD patients and 16 age- and sex-matched normal controls were investigated on polysomnography on two consecutive nights. Six PTSD-only patients and 15 PTSD patients with major depressive disorder (MDD) were also compared to normal controls. Sleep variables were correlated with PTSD symptoms. Results:, Compared to the normal controls, the PTSD patients with MDD had difficulty initiating sleep, poor sleep efficiency, decreased total sleep time, decreased slow wave sleep (SWS), and a reduced rapid eye movement (REM) sleep latency. The PTSD patients without any comorbid psychiatric disorders had moderately significant disturbances of sleep continuity, and decreased SWS, but no abnormalities of REM sleep. REM sleep latency was inversely proportional to the severity of startle response. SWS was found to be inversely correlated with the severity of psychogenic amnesia. Conclusions:, PTSD patients have disturbance of sleep continuity, and SWS deficit, without the impact of comorbid depression on sleep. The relationship between SWS and the inability to recall an important aspect of trauma may indicate the role of sleep in the consolidation of traumatic memories. The relationship between the severity of the startle response and REM latency may suggest that REM sleep physiology shares common substrates with the symptoms of PTSD. [source] Abnormal cerebellum density in victims of rape with post-traumatic stress disorder: Voxel-based analysis of magnetic resonance imaging investigationASIA-PACIFIC PSYCHIATRY, Issue 3 2010Shuang-Ge Sui MD MBA Abstract Introduction: Based on early studies of non-motor function in the cerebellum and dysfunction in the cerebellum of post-traumatic stress disorder (PTSD) patients, we presumed that the cerebellum was involved in the neuropathology of cognitive and emotional processing of PTSD patients, while the density of some sub-areas of the cerebellum of PTSD patients was most likely abnormal. Methods: Eleven female victims of rape with PTSD and 12 age-matched female normal controls received 1.5 T 3D magnetic resonance imaging (MRI) scan. The scans were then analyzed using the voxel-based morphometry 2 (VBM2) toolbox. Results: Victims of rape with PTSD showed increased cerebellum density on the left side compared with normal controls (P<0.001), especially in the pyramis (x=,9, y=,72, z=,36; k=519; t=4.70), uvula (x=,4, y=,66, z=,35; k=256; t=4.02), declive (x=,6, y=,69, z=,30; k=213; t=3.84) and nodule (x=,4, y=,63, z=,31; k=147; t=3.93). In addition, compared with normal controls, the PTSD group showed significant differences in gray matter density of other brain areas, including the frontal lobe, parietal lobe, occipital lobe (P<0.001), insula, posterior cingulate, amygdala and hippocampus (P<0.005). Discussion: These finding suggest that the cerebellum may be involved in the neuropathology and functional compensation in the neurocircuitry of PTSD. [source] |
