RESUMO

OBJECTIVE: The present study aimed to investigate the association between self-reported awake/sleep bruxism, and orofacial pain with post-traumatic stress disorder (PTSD). METHODS: A case-control study with a convenience sample was designed. Participants were recruited from a university-based Trauma Ambulatory. The diagnosis of PTSD was established through a clinical interview and the Structured Clinical Interview (SCID-I/P). Thirty-eight PTSD patients and 38 controls completed the Research Diagnostic Criteria for Temporomandibular Disorders Axis-II to categorize awake/sleep bruxism and orofacial pain. Following this, we performed a short clinical examination of the temporomandibular joint and extraoral muscles. RESULTS: Adjusted logistic regression analysis showed that awake bruxism was associated with PTSD (OR = 3.38, 95% CI = 1.01-11.27, p = 0.047). Sleep bruxism was not associated with any covariate included in the model. In a Poisson regression model, PTSD (IRR = 3.01, 95% CI = 1.38-6.55, p = 0.005) and the muscle pain/discomfort (IRR = 5.12, 95% CI = 2.80-9.36, p < 0.001) were significant predictors for current orofacial pain. CONCLUSIONS: PTSD was associated with self-reported awake bruxism and low-intensity orofacial pain. These conditions were frequent outcomes in patients previously exposed to traumatic events. CLINICAL RELEVANCE: We suggest including a two-question screening for bruxism in psychiatry/psychology interviews to improve under-identification and to prevent harmful consequences at the orofacial level.

RESUMO

Delivering electroconvulsive therapy (ECT) during the reconsolidation of traumatic memories may enhance the treatment efficacy in posttraumatic stress disorder (PTSD). To test this, 14 patients with severe and refractory PTSD were randomly allocated to receive ECT sessions either after retrieving the traumatic (n=8) or a neutral (n=6) memory. We found that delivering ECT after retrieving the traumatic memory enhanced the improvement of PTSD symptoms and the reduction of subjective reactivity to the traumatic memory. Reduction in anxiety and mood symptoms and physiological reactivity to the traumatic memory were observed in the sample as a whole regardless of memory retrieval.

RESUMO

BACKGROUND: Post-traumatic stress disorder (PTSD) is a prevalent mental health condition that is often associated with psychiatric comorbidities and changes in quality of life. Prolonged exposure therapy (PE) is considered the gold standard psychological treatment for PTSD, but treatment resistance and relapse rates are high. Trial-based cognitive therapy (TBCT) is an effective treatment for depression and social anxiety disorder, and its structure seems particularly promising for PTSD. Therefore, we evaluated the efficacy of TBCT compared to PE in patients with PTSD. METHODS: Ninety-five patients (77.6% females) who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria for PTSD were randomly assigned to receive either TBCT (n = 44) or PE (n = 51). Patients were evaluated before and after treatment, and at follow-up 3 months after treatment. The primary outcome was improvement in PTSD symptoms as assessed by the Davidson Trauma Scale (DTS). Secondary outcomes were depression, anxiety, and dysfunctional attitudes assessed by the Beck Depression/Anxiety Inventories and Dysfunctional Attitudes Scale, as well as the dropout rate. RESULTS: A significant reduction in DTS scores was observed in both arms, but no significant difference between treatments. Regarding the secondary outcomes, we found significant differences in depressive symptoms in favor of TBCT, and the dropout rate was lower in the TBCT group than the PE group. CONCLUSION: Our preliminary results suggest that TBCT may be an effective alternative for treating PTSD. Further research is needed to better understand its role and the mechanisms of change in the treatment of this disorder.

RESUMO

BACKGROUND: Evidence suggests that extinction during memory reconsolidation diminishes the return of defensive responses. In order to translate these effects to the clinical setting, we tested whether retrieving a traumatic memory and delivering a brief two-sessions imaginal exposure intervention during its reconsolidation would produce stronger decreases in reactivity to these memories than standard imaginal exposure method. METHODS: Participants with Post-Traumatic Stress Disorder (PTSD) had either their traumatic (n = 21) or a neutral (n = 21) memory retrieved 1 h before an imaginal exposure session for two consecutive days. One day before and one day after, participants were exposed to script-driven imagery of their traumatic event, during which skin conductance responses were measured and, immediately after, subjective responses were assessed by means of Visual Analogue Scales. RESULTS: Traumatic retrieval improved the physiological, but not the subjective effects of imaginal exposure intervention on over-reactivity to traumatic memories. CONCLUSIONS: Our results suggest that delivering extinction-based treatments over the reconsolidation of traumatic memories may enhance its effects. These results suggest that this is a promising path toward the development of new therapeutic techniques.
