RESUMO

Poor integration and landmark views make opposing claims regarding the relationship between post-traumatic stress symptoms and trauma memory integration. This study tested these approaches using an event cluster paradigm. In total, 126 participants (Nptsd = 61; Nnon-ptsd = 65) remembered memories from the same story as trauma, positive and neutral memories and reported whether each memory was directly retrieved or generated. Moreover, the retrieval time (RT) was recorded. Finally, the participants completed the Centrality of Event Scale (CES) and Post-traumatic Stress Disorder Symptom Scale-Self Report (PSS-SR). The results demonstrated that participants with post-traumatic stress disorder (PTSD) recalled their clusters of memories more slowly and less directly than those without PTSD. However, the CES predicted PTSD severity more strongly than RT and retrieval strategy. These results suggest that traumatic memories are more disorganised but perceived as more central in PTSD.

RESUMO

OBJECTIVE: We aimed to examine white matter microstructure and connectivity in individuals with obsessive-compulsive disorder (OCD) and their unaffected siblings, relative to healthy controls. METHODS: Diffusion-weighted magnetic resonance imaging (dMRI) scans were acquired in 30 patients with OCD, 21 unaffected siblings, and 31 controls. We examined white matter microstructure using measures of fractional anisotropy (FA), radial diffusivity (RD), and axial diffusivity (AD). Structural networks were examined using network-based statistic (NBS). RESULTS: Compared to controls, OCD patients showed significantly reduced FA and increased RD in clusters traversing the left forceps minor, inferior fronto-occipital fasciculus, anterior thalamic radiation, and cingulum. Furthermore, the OCD group displayed significantly weaker connectivity (quantified by the streamline count) compared to controls in the right hemisphere, most notably in edges connecting subcortical structures to temporo-occipital cortical regions. The sibling group showed intermediate streamline counts, FA and RD values between OCD and healthy control groups in connections found to be abnormal in patients with OCD. However, these reductions did not significantly differ compared to controls. CONCLUSION: Therefore, siblings of OCD patients display intermediate levels in dMRI measures of microstructure and connectivity, suggesting white matter abnormalities might be related to the familial predisposition for OCD.

RESUMO

Clinical correlates of obsessive-compulsive symptoms (OCS) were evaluated in 100 adult consecutive outpatients with epilepsy, using the Obsessive-Compulsive Inventory (OCI-R), Beck Depression Inventory (BDI), Dissociative Experiences Scale (DES-II), and the Schizotypal Personality Questionnaire (SPQ). Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) was applied to determine the types and severity of OCS to the 45 patients with epilepsy who were over 21 points on the OCI-R scale and 30 patients who were with diagnosed obsessive-compulsive disorder (OCD) among the patients in the psychiatry outpatient clinic, as a control group. As a result, it was found that patients with epilepsy with OCS tend to have more symmetry/exactness obsessions and compulsions, whereas patients with OCD had significantly more contamination/cleaning and aggressiveness obsessions and compulsions. In addition, OCS was found to be significantly higher in temporal lobe epilepsy (TLE) and extratemporal epilepsy than generalized epilepsy. However, OCS were correlated with depression, dissociation, and schizotypy in patients with epilepsy, while only depression was predictive when regression analysis was performed for OCS. This study is the first study to compare patients with OCD with patients with epilepsy in terms of the nature of OCS and first identified the differences in OCS dimensions between patients with epilepsy with OCS and patients with OCD.

RESUMO

OBJECTIVE: To investigate effectiveness of two different high-frequency repetitive transcranial magnetic stimulation (rTMS) protocols on pain, fatigue, quality of life (QoL) and depression in female patients with fibromyalgia. METHODS: Thirty patients were randomized into three groups. Fifteen sessions of 10 Hz (90% resting motor threshold-RMT, 1200 pulses) rTMS were applied to left primary motor cortex and left dorsolateral prefrontal cortex (DLPFC) in Group M1 (n:10) and Group DLPFC (n:10), respectively. Group sham (n = 10) received 15 sessions of sham rTMS over 3 weeks. Visual Analogue Scale, Fibromyalgia Impact Questionnaire, Fatigue Severity Scale, Short-form 36, and Beck Depression Inventory were assessed at baseline and at the end of the treatments by a blinded-experienced assessor. RESULTS: Significant improvements in pain, QoL, and depression scores were observed in three groups. However, improvements in depression, physical functioning, physical role functioning, and general health perceptions were greater in active rTMS groups than in sham group. Emotional role functioning was only improved in Group M1. The decrease in VAS scores was significantly greater in Group M1 when compared to sham group. Change in physical role functioning was significantly greater in Group DLPFC than in Group M1. CONCLUSIONS: Significant improvements in physical role functioning, physical functioning, depression, and general health perceptions were achieved in active rTMS groups. Further clinical studies on larger samples involving both sexes with longer follow-up durations are needed.

RESUMO

We aimed to examine the whole-brain white matter connectivity and local topology of reward system nodes in patients with alcohol use disorder (AUD) and unaffected siblings, relative to healthy comparison individuals. Diffusion-weighted magnetic resonance imaging scans were acquired from 18 patients with AUD, 15 unaffected siblings of AUD patients and 15 healthy controls. Structural networks were examined using network-based statistic and connectomic analysis. Connectomic analysis showed a significant ordered difference in normalized rich club organization (AUD < Siblings < Controls). We also found rank ordered differences (Control > Sibling > AUD) for both nodal clustering coefficient and nodal local efficiency in reward system nodes, particularly left caudate, right putamen and left hippocampus. Network-based statistic analyses showed that AUD group had significantly weaker connectivity than controls in the right hemisphere, mostly in the edges connecting putamen and hippocampus with other brain regions. Our results suggest that reward system network abnormalities, especially in subcortical structures, and impairments in rich-club organization might be related to the familial predisposition for AUD.

RESUMO

A growing body of research evidence documents the substantial associations between obsessive-compulsive disorder (OCD) and dissociation. This article describes the development and preliminary psychometric properties of the Van Obsessional Dissociation Questionnaire (VOD-Q). Obsessional dissociation is defined as a tendency to dissociate in reaction to distressing, unwanted and intrusive thoughts, images and impulses. The screening tool is conceptualized to tap obsessional dissociation across three dimensions: obsessional absorption, obsessional depersonalization/ derealization and obsessional amnesia. The VOD-Q, the Padua Inventory-Revised (PI-R), the Dissociative Experiences Scale (DES), and the Obsessive Belief Questionnaire (OBQ-44) were administered in this study. The results showed that the VOD-Q had excellent test-retest reliability (ranging from 0.73 to 0.90) and internal consistency (ranging from 0.90 to 0.97). The VOD-Q total and subscale scores were significantly associated with measures of obsessive-compulsive symptoms and dissociative experiences. OCD patients scored significantly higher on the VOD-Q than community participants. Based on the present findings, the VOD-Q appears to be a reliable and valid instrument for the measurement of obsessional dissociative experiences.

RESUMO

BACKGROUND: Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a promising scale for assessing frequency and severity of symptom dimensions. The main objective of the study was to assess the psychometric properties of the DY-BOCS in a large sample of children and adolescents from Turkey. METHODS: We studied 143 children and adolescents, 7-18years, with well characterized DSM-IV-R OCD, ascertained from seven collaborating university or state hospital sites. We compared the DY-BOCS scores with the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), the Children's Depression Inventory (CDI), the Yale Global Tic Severity Scale (YGTSS) and the Child Behavior Checklist 6-18years (CBCL 6-18). RESULTS: The internal consistency of the DY-BOCS symptom dimensions and inter-rater agreement of component scores were excellent. The agreement between global DY-BOCS score and the total CY-BOCS score was highly significant (Pearson's r=0.55, p<0.0001). Severity scores for individual symptom dimensions were independent of one another, only modestly correlating with the global ratings, and were also differentially related to ratings of depression, anxiety and tic severity. CONCLUSION: The DY-BOCS is a reliable and valid instrument for assessing multiple aspects of OCD symptom severity in children and adolescents from Turkey.

RESUMO

OBJECTIVE: Our aim was to investigate cognitive models of OCD via the influence of mothers' cognitive appraisals on children's cognitions and OCD symptoms. METHOD: Our sample consisted of 21 adolescents with OCD, their mothers and 27 parent-child dyads for control group without OCD. Subjects with OCD and their mothers were administered The Beck Depression Inventory (BDI), The Thought-Action Fusion Scale (TAFS), The White Bear Suppression Inventory (WBSI), The Padua Inventory-Revised (PI-R) and The Penn Inventory of Scrupulosity (PIOS). RESULTS: While the BDI (t=2.18, p<0.05) and TAF Morality (t=2.18, p<0.05) scores of the mothers of OCD subjects were significantly higher than the mothers of control subjects, the comparisons for the PI, TAF likelihood and PIOS scores of groups were not significant. Intradyadic correlation revealed significant relationships for PI-Rumination, PI-Checking and WBSI scales between the scores of parent and child in OCD dyads, (respectively, r=0.49, P=0.11; r=0.37, P=0.045; and r=0.47, P=0.014). There was no significant relationship in the control group. CONCLUSION: Our results partially supported that mothers' cognitive appraisals are associated with the cognitive appraisal of adolescents. A cognitive intradyadic interaction between mother and child might be more likely in the presence of OCD in adolescents.

RESUMO

A moral/religious subtype of obsessive compulsive disorder has been termed as scrupulosity by mental health professionals. Since ultimate feared consequence in scrupulous individuals is religious or moral in nature, it also presents interesting and difficult issue for religious authorities. This article focuses on various aspects of scrupulosity that have until now been poorly conceptualized in Islamic world and provides a conceptual cognitive framework and analysis of scrupulosity according to Islamic sources.

RESUMO

OBJECTIVE: Seasonality is one of the most interesting but still elusive issue in suicide research. Linkages of seasonality in suicides to possible contributors such as gender, type of method used, and climatic factors have received attention in different cultures. We aimed at evaluating seasonal trends in suicidal behaviour according to demographic characteristics, reasons for self-destructive behaviour and means preferred in suicide. METHODS: Our aim was to assess the seasonal variation in self-destructive behaviour in terms of completed and attempted suicides in a 3-year time period from 2008 to 2010 in Van, Turkey. A total of 1448 cases were registered over a 3-year time period in the city. Seasonal deviations in demographic characteristics, reasons for suicide, and methods of suicide were evaluated. RESULTS: Seasonal distribution of both completed and attempted suicides by gender did not significantly deviate. On the other hand, we found a significant decline in self-destructive behaviours among those who were single and student in the spring. We found a peak in self-destructive behaviours in the autumn among Individuals who suffer from psychological problems. CONCLUSIONS: Subjects with psychological difficulties were more prone to commit suicide in autumn. Seasonal differences in methods of suicide used by suicidal subjects were not significant.

RESUMO

OBJECTIVE: There is mounting evidence indicating that oxidative and inflammatory processes may have an important role in the pathogenesis of panic disorder (PD). PD is a heterogeneous disease, and panic attacks are divided according to the different symptom clusters as respiratory, nocturnal, non-fearful, cognitive, or vestibular subtypes. The aim of this study was to compare whole-blood and serum superoxide dismutase (SOD), glutathione peroxidase and adenosine deaminase activities in PD patients with/without nocturnal, respiratory subtypes and healthy subjects. METHODS: The study was conducted including 60 patients with PD and 30 healthy control subjects. The Panic Attack Symptom Checklist, Panic and Agoraphobia Scale, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale were administered to the patients. Biochemical analyses were performed after all the blood samples were collected. RESULTS: We found that whole-blood SOD and glutathione peroxidase activities of patients were significantly lower and adenosine deaminase activities of patients were higher than those of healthy controls. There were no statistically significant differences between respiratory and nocturnal subtypes. In addition, there were no marked relationships between the duration of illness and panic-agoraphobia scores of patients with nocturnal subtypes. Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale scores of patients with the nocturnal subtype were markedly higher than those of patients without the nocturnal subtype. CONCLUSION: The results suggest that oxidative and inflammatory processes may play a role in the pathophysiology of PD. These findings may support the idea that both nocturnal and respiratory subtypes of PD have different symptom clusters of the same disease.

RESUMO

OBJECTIVE: Previous studies have indicated that obsessive compulsive disorder (OCD) is associated with childhood traumatic experiences and higher levels of dissociation. Dissociative tendency may arise when individual attempt to incorporate adverse experiences into cognitive schema. METHODS: We investigated the possible links among childhood trauma, dissociation, and cognitive processes. We evaluated 95 patients with OCD using the Beck Depression Inventory (BDI), Thought-Action Fusion Scale (TAFS), Metacognitions Questionnaire (MCQ-30), White Bear Suppression Inventory (WBSI), Dissociative Experiences Scale (DES), and Childhood Trauma Questionnaire (CTQ-28). RESULTS: The CTQ-28 total scores were not associated with Y-BOCS total, Y-BOCS insight, BDI, TAFS, MCQ-30, and WBSI scores. The TAFS Total, MCQ-30, WBSI, and BDI scores were significantly associated with DES scores. Regression analysis revealed that MCQ-30 and WBSI scores significantly predicted the DES scores. CONCLUSIONS: These results suggest that in spite of pathological connotation of dissociative experiences, dissociation may primarily constitute a cognitive trait which is strongly associated with cognitive processes.

RESUMO

Little is known about the underlying neurobiological mechanisms in patients with obsessive-compulsive disorder (OCD). We aimed to examine cortical thickness and surface area in individuals with OCD and their unaffected siblings, comparing them to healthy controls. 30 patients with OCD, 21 unaffected siblings (SIB) and 30 controls underwent structural magnetic resonance imaging. Structural images were analyzed using the FreeSurfer software package (version 6.0). Compared to healthy controls, both OCD and SIB groups showed significantly lower cortical thickness in the right anterior insula. Surface areas of the superior frontal gyrus, paracentral gyrus and precuneus of the right hemisphere were also reduced in OCD patients compared to controls. There were no significant differences in cortical thickness and surface area between the OCD and SIB groups. We did not detect any significant differences in subcortical volumes between groups. Lower cortical thickness in the right anterior insula in both OCD patients and unaffected siblings may represent a potential structural endophenotype for OCD.

RESUMO

OBJECTIVE: The aim of the present study was to investigate the relationship between nightmares and acute myocardial infarction (AMI) occurring during sleep, and also to evaluate the influence of several related factors. METHOD: The sample comprised AMI patients who had been admitted to the coronary care unit. The patients were grouped into two categories; the asleep-AMI group consisted of 36 patients who had the onset of symptoms of AMI during sleep, and the awake-AMI group included 183 patients who had AMI while they were awake. The sleep quality and dream anxiety for the 1-month interval before AMI were assessed with Pittsburgh Sleep Quality Index (PSQI) and Van Dream Anxiety Scale (VDAS), respectively. RESULTS: Asleep-AMI patients reported significantly poorer subjective sleep quality, significantly higher global PSQI scores, and displayed significantly higher nightmare frequency, difficulty in falling asleep after a nightmare, higher autonomic hyperactivity, dream recall frequency, daytime anxiety, psychological problems, and higher global dream anxiety scores than awake-AMI patients. CONCLUSION: The present study suggests that sleep anxiety and related emotions are associated with AMI during sleep.

RESUMO

OBJECTIVE: To investigate the comparative efficacy of aripiprazole and risperidone as augmenting agents in the treatment of obsessive-compulsive disorder (OCD) patients who did not show a ≥35% decrease in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) after 12-week monotherapy with selective serotonin reuptake inhibitors (SSRIs). METHODS: The study consists of two different periods of treatment: a 12-week prospective period to determine resistance to SSRI treatment and an 8-week single-blind addition period for refractory patients only. Ninety patients were randomly assigned to receive one of the SSRI treatments. Sixty-nine patients (76.6%) completed the 12-week SSRI monotherapy period. Forty-one patients (59.4%) were considered refractory and were randomised to receive either risperidone (20 patients, 3 mgr daily) or aripiprazole (21 patients, 15 mgr daily) as augmentation to SSRI treatment. Sixteen patients (76.2%) in the aripiprazole group and 18 patients (84%) in the risperidone group completed the 8-week treatment period. RESULTS: Eight patients (50%) in aripiprazole and 13 patients (72.2%) in risperidone group met response criteria of Y-BOCS decrease ≥35% at the end of the study. The risperidone group showed a significant improvement in Y-BOCS obsession scores compared with aripiprazole. CONCLUSIONS: The present findings suggest that risperidone may be more effective than aripiprazole.

RESUMO

OBJECTIVE: We aimed to assess whether cognitive processes change over time in patients with obsessive-compulsive disorder (OCD) receiving selective serotonin reuptake inhibitors without cognitive behavioral therapy and to investigate the factors associated with probable cognitive changes. METHODS: During the 16 weeks of the study, 55 patients who met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for OCD received open-label treatment with sertraline (100-200 mg/d) or fluoxetine (40-80 mg/d) and were assessed using the Yale-Brown Obsessive-Compulsive Scale, Beck Depression Inventory (BDI), Thought-Action Fusion Scale (TAFS), Metacognitions Questionnaire (MCQ-30), and White Bear Suppression Inventory (WBSI). RESULTS: The Yale-Brown Obsessive-Compulsive Scale (P < .001), BDI (P < .001), TAFS morality (P < .005), MCQ-30 (P < .01), and WBSI (P < .005) scores at follow-up were significantly lower than baseline scores. When we excluded OCD patients with depressive disorder (n = 12), statistical significance in paired comparisons for MCQ and WBSI disappeared. Similarly, when OCD patients with religious obsessions (n = 16) were excluded, paired comparisons for MCQ and TAF morality were not statistically significant. Changes in BDI, TAFS morality, MCQ-30, and WBSI (P < .005) were significantly correlated with changes in severity of obsessions, but not that of compulsions. After controlling for the change in depression severity, significant correlations between changes in obsessive and cognitive scales did not continue to have statistical significance. The BDI changes (P < .05) significantly explained the changes in symptom severity in a linear regression model. CONCLUSIONS: Our findings suggest that selective serotonin reuptake inhibitors can change appraisals of obsessive intrusions via their effects on negative emotions.

RESUMO

OBJECTIVE: The present study examined whether obsessive beliefs change over time in the OCD patients receiving selective serotonin reuptake inhibitors (SSRIs) and the impact of obsessive beliefs in treatment response. METHODS: In the first part of a two-stage study comparing the efficacy of antipsychotics as augmenting agent in SSRI-resistant OCD patients, 57 patients were interviewed with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Hamilton Depression Rating Scale (HDRS) and Obsessive Beliefs Questionnaire-44 (OBQ-44) before and after 12-week of SSRI treatment period. RESULTS: All OBQ-44 subscale scores significantly decreased with SSRI treatment. The mean changes in OBQ-44 Importance and Control of Intrusive Thoughts (I/CT) subscale and HDRS total scores of responders were significantly higher than those of SSRI-resistant patients. The baseline OBQ-44 P/C and Y-BOCS obsession subscale scores significantly predicted the treatment resistance in a logistic regression model. CONCLUSIONS: The alleviation of negative mood by SSRIs may help the sufferer to disengage from dysfunctional appraisals. Since individuals with highly obsessive beliefs about P/C are more likely to be resistant to SSRI treatment, the treatment of OCD can be made more effective when focusing on altering appraisals about P/C.

RESUMO

Recent theories suggest a shift from model-based goal-directed to model-free habitual decision-making in obsessive-compulsive disorder (OCD). However, it is yet unclear, whether this shift in the decision process is heritable. We investigated 32 patients with OCD, 27 unaffected siblings (SIBs) and 31 healthy controls (HCs) using the two-step task. We computed behavioral and reaction time analyses and fitted a computational model to assess the balance between model-based and model-free control. 80 subjects also underwent structural imaging. We observed a significant ordered effect for the shift towards model-free control in the direction OCD > SIB > HC in our computational parameter of interest. However less directed analyses revealed no shift towards model-free control in OCDs. Nonetheless, we found evidence for reduced model-based control in OCDs compared to HCs and SIBs via 2nd stage reaction time analyses. In this measure SIBs also showed higher levels of model-based control than HCs. Across all subjects these effects were associated with the surface area of the left medial/right dorsolateral prefrontal cortex. Moreover, correlations between bilateral putamen/right caudate volumes and these effects varied as a function of group: they were negative in SIBs and OCDs, but positive in HCs. Associations between fronto-striatal regions and model-based reaction time effects point to a potential endophenotype for OCD.

RESUMO

Background and Objectives: There is growing research indicating that event centrality strongly predicts posttraumatic stress disorder (PTSD). However, there is not much research on what makes a traumatic event central to one's life story. One reason a traumatic memory becomes a reference point for one's life story is that it brings about significant changes in one's life. This study investigated the relationships between transitional impact of an event, event centrality, and PTSD symptoms. Specifically, it tested whether higher negative changes were associated with higher levels of event centrality and PTSD symptoms. It also investigated whether event centrality mediated the relationship between transitional impact and PTSD severity.Methods: 101 individuals diagnosed with PTSD completed the Transitional Impact Scale (TIS), Centrality of Event Scale, and Impact of Event Scale-Revised regarding their traumatic experiences. Furthermore, they responded to the Posttraumatic Stress Disorder Symptom Scale-Self Report (PSS-SR), Traumatic Events Checklist (TELC), and Beck Anxiety Inventory (BAI).Results and Conclusions: Results indicate that (a) the TIS had valid and reliable psychometric properties in a PTSD sample, (b) most of the traumatic events received high negative psychological and material change scores, and (c) event centrality mediated the relationship between transitional impact and PTSD severity.

RESUMO

OBJECTIVE: Obsessive compulsive disorder (OCD) is an illness that considerably influences the family, academic, occupational and social functioning of patients. In this study, we aimed to investigate the impact of psychopharmacological treatment on quality of life in patients with OCD. METHOD: Using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Hamilton Depression Rating Scale (HDRS) and the World Health Organization Quality of Life Measurement Instrument Short Form, Turkish Version (WHOQOL-Bref TR) we assessed 53 patients who met the DSM-IV criteria for OCD to establish baseline values. The patients were consecutively assigned to receive either sertraline (100-200 mg/day), fluvoxamine (200-300 mg/day) or paroxetine (40-80 mg/day). We reassessed 36 (68%) of the initial group after 12 weeks. RESULTS: The scores of obsession, compulsion and depression severity at follow-up were significantly lower than those of baseline scores. There is no significant difference between the pre and post-treatment quality of life domain scores. While psychological health scores at follow-up was significantly associated with baseline HDRS scores (r=-0.35, p<0.05), social relationship scores at follow-up was significantly associated with baseline social relationship scores (r=0.63, p<0.001) and compulsion scores (r=-0.37, p<0.05). Regression analyses revealed that social relationship scores at follow-up was associated with baseline compulsion severity whereas other follow-up quality of life domain scores were not predicted by any baseline variable. CONCLUSIONS: Clinical viewpoint and objective evaluations should be essential in the evaluation of treatment outcome, and quality of life researches may be important complement to clinical researches.
