[Mindfulness-Oriented Recovery Enhancement (MORE): integrative treatment for chronic pain]. / Mindfulness-Oriented Recovery Enhancement (MORE) : traitement intégratif pour la douleur chronique.

Chronic pain requires an integrative approach. The prescription of opioids is increasing in Europe, including Switzerland, for the -treatment of chronic pain, despite their modest effectiveness. Mindfulness-based interventions have demonstrated their effectiveness in the management of chronic pain. The MORE program (Mindfulness-Oriented Recovery Enhancement) is an integrative therapy that uses mindfulness practices to help patients develop new positive beliefs and regain meaning, motivation and pleasure. The MORE program has been proven effective in reducing opioids and increasing well-being in patients suffering from chronic pain and thus constitutes a promising therapeutic approach.

La douleur chronique nécessite une approche intégrative. La prescription des opiacés augmente de plus en plus en Europe, y compris en Suisse, pour le traitement de la douleur chronique, malgré leur efficacité modeste. Les interventions basées sur la méditation de pleine conscience ont démontré leur efficacité quant à la prise en charge de la douleur chronique. Le programme MORE (Mindfulness-Oriented Recovery Enhancement) est une thérapie intégrative qui utilise des pratiques de pleine conscience afin d'aider les patients à développer des nouvelles croyances positives et de retrouver le sens, la motivation et le plaisir. Ce programme a été prouvé ­efficace quant à la réduction des opiacés et l'augmentation du bien-être chez les patients souffrant de douleurs chroniques. Il constitue ainsi une approche thérapeutique prometteuse.

Eye-gaze processing in the broader bipolar phenotype revealed by electrical neuroimaging.

Previous studies have documented atypical brain responses to faces in individuals with bipolar disorder (BD) and in their relatives. In view of previous findings of atypical face processing in youths at risk for BD, the aim of this study was to examine whether BD patients and offspring would show differential activation in networks of the social brain when processing eye-gaze. Data from 18 euthymic BD patients and 18 offspring, as well as 36 age-matched healthy controls, were collected using a delayed face-matching paradigm, event related potentials and electrical neuroimaging methods. The P200 component, which is implicated in facial cues decoding, differentiated the BD groups from their age-matched controls. P200 source reconstruction indicates impairments conveyed by eye-contact in a network involved in experiencing others' social intentions in BD patients (supplementary motor cortex, precentral gyrus, inferior parietal lobe), and the engagement of compensatory prefrontal mechanisms for modulating these functions in BD offspring. When viewing faces that had an averted gaze, BD patients and offspring showed a hypo-activation, compared to controls, particularly in regions involved in experiencing others' feelings (post-central gyrus in BD patients / ventral premotor cortex in offspring). Therefore, the neural mechanism for decoding shifts in eye-gaze may be a familial characteristic of BD.

Psychiatric disorders among offspring of patients with Bipolar and Borderline Personality Disorder.

OBJECTIVE: As part of a larger study investigating biological risk factors for bipolar disorder (BD) and borderline personality disorder (BPD), we investigated the prevalence of psychiatric diagnoses presented by young BD or BPD offspring. With respect to the scarcity of studies interested in psychiatric disorders among BPD offspring, we have chosen to report these results despite the small sample size for a prevalence study. METHOD: We recruited 21 BD and 22 BPD offspring and 23 control subjects. All subjects were assessed with a structured interview. RESULTS: Our main finding suggests that BPD offspring present a higher rate of psychiatric disorders compared to BD offspring. Attention deficit and hyperactivity disorder was the most prevalent disorder. CONCLUSION: Our results contribute to the evidence that offspring of patients with BPD, are at high risk with regard to their mental health and deserve both more research and special attention at the clinical level.

Rumination related activity in brain networks mediating attentional switching in euthymic bipolar patients.

INTRODUCTION: Mood disorder patients have a tendency to be more internally oriented, with difficulties in switching attentional focus, which might result in the generation of negative thoughts, such as rumination. The present study explored self-referential neural activity correlating with rumination tendency and attentional switching capacity in bipolar disorder. METHODS: Twenty euthymic bipolar patients and twenty matched healthy controls underwent a novel introspection task of switching between internally and externally focused attention during a word processing task, while their brain activity was assessed using functional MRI. RESULTS: During internal focus, higher activity in self-related regions (mPFC, PCC) was found in euthymic bipolar patients as compared to controls, verifying the hypothesis of exaggerated recruitment of self-referential processes in bipolar subjects. Switching from internal to external focus revealed higher parahippocampal activity in patients as compared to controls, additionally more pronounced when switching away from negative as compared to positive self-referential information. Furthermore, rumination traits correlated with activity in PCC, subgenual and pregenual ACC, and bilateral anterior insula during repetition of internal focus, specifically when evaluating negative words. Finally, we used ACC subregions that correlated with tendency to ruminate as seeds for a whole brain connectivity analysis. Patients showed stronger connectivity between sgACC (seed), pgACC, dPFC, and anterior insula during internal focus, whereas pgACC (seed) was more strongly connected to parahippocampal gyrus when switching from internal to external focus. CONCLUSIONS: These findings reveal an overactive rumination-related network whose activity is enhanced by negative information in euthymic bipolar patients, which could possibly contribute to impaired switching of thoughts away from internal attention.

Anxiety disorders and childhood maltreatment as predictors of outcome in bipolar disorder.

BACKGROUND: Comorbid anxiety disorders and childhood maltreatment have each been linked with unfavourable outcomes in people with bipolar disorder. Because childhood maltreatment is associated with anxiety disorders in this population, their respective predictive value remains to be determined. METHODS: In 174 adults with bipolar disorder, we assessed childhood maltreatment using the Childhood Trauma Questionnaire and lifetime anxiety disorders with the MINI International Neuropsychiatric Interview. We constructed an overall index of severity of bipolar disorder as a sum of six indicators (unemployment, psychotic symptoms, more than five manic episodes, more than five depressive episodes, suicide attempt, and hospital admission). We tested the relationship between childhood maltreatment, the number of anxiety disorders and the overall severity index using ordered logistic regression. RESULTS: The number of lifetime anxiety disorders was associated with the overall severity index (OR = 1.43, 95%CI = 1.01-2.04, p = 0.047). This relationship was only slightly attenuated when controlled for childhood maltreatment (OR = 1.39, 95%CI = 0.97-2.00, p = 0.069). The relationship between childhood maltreatment and the overall severity index was not statistically significant (OR = 1.26, 95%CI = 0.92-1.74, p = 0.151). Secondary analyses revealed that childhood maltreatment was associated with suicide attempts (OR = 1.70, 95%CI = 1.15-2.51, p = 0.008) and obsessive compulsive disorder was associated with the overall severity index (OR = 9.56, 95%CI = 2.20-41.47, p = 0.003). LIMITATIONS: This was a cross-sectional study with a moderate-sized sample recruited from a specialist program. CONCLUSIONS: While comorbid anxiety disorders are associated with the overall severity of bipolar disorder, childhood maltreatment is specifically associated with suicide attempts. Clinicians should systematically assess both factors. Interventions to improve outcomes of people with bipolar disorder with comorbid anxiety disorders and history of childhood maltreatment are needed.

Dysfunctional gaze processing in bipolar disorder.

Gaze conveys emotional information, and humans present sensitivity to its direction from the earliest days of life. Bipolar disorder is a disease characterized by fluctuating states of emotional and cognitive dysregulation. To explore the role of attentional control on face processing in bipolar patients (BP) we used gaze direction as an emotion modulation parameter in a two-back Working Memory (WM) task while high-density EEG data were acquired. Since gaze direction influences emotional attributions to faces with neutral expressions as well, we presented neutral faces with direct and averted gaze. Nineteen euthymic BP and a sample of age- and gender-matched controls were examined. In BP we observed diminished P200 and augmented P300 evoked responses, differentially modulated by non-repeated or repeated faces, as well as by gaze direction. BP showed a reduced P200 amplitude, significantly stronger for faces with direct gaze than averted gaze. Source localization of P200 indicated decreased activity in sensory-motor regions and frontal areas suggestive of abnormal affective processing of neutral faces. The present study provides neurophysiological evidence for abnormal gaze processing in BP and suggests dysfunctional processing of direct eye contact as a prominent characteristic of bipolar disorder.

Self-Reported Long-Term Benefits of Mindfulness-Based Cognitive Therapy in Patients with Bipolar Disorder.

OBJECTIVES: This study focused on patients with bipolar disorder (BD), several years after their participation in mindfulness-based cognitive therapy (MBCT). It aimed at documenting sustained mindfulness practice, perceived long-term benefit from the program, and changes regarded as direct consequences of the intervention. DESIGN: This cross-sectional survey took place at least 2 years after MBCT for 70.4% of participants. LOCATION: It was conducted in two specialized outpatient units for BDs that are part of the Geneva University Hospitals (Switzerland) and the Sainte-Anne Hospital in Paris (France). SUBJECTS: Eligibility criteria were a diagnosis of BD according to DSM-IV and participation in at least four MBCT sessions. Response rate was 66.4%. The final sample included 71 outpatients (71.8% bipolar I, 28.2% bipolar II). OUTCOME MEASURES: A questionnaire retrospectively assessed patient-perceived change, benefit from MBCT, and current mindfulness practice. RESULTS: Proportions of respondents who practiced mindfulness at least once a week were 54.9% for formal practice (body scan, sitting meditation, mindful walking, or movements) and 57.7% for informal practice (mindful daily activities). Perceived benefit for the prevention of relapse was moderate, but patients acknowledged long-lasting effects and persistent changes in their way of life. Formal mindfulness practice at least once a week tended to be associated with increased long-lasting effects (p = 0.052), whereas regular informal practice and mindful breathing were significantly associated with persistent changes in daily life (p = 0.038) and better prevention of depressive relapse (p = 0.035), respectively. The most frequently reported positive change was increased awareness of being able to improve one's health. CONCLUSIONS: Despite methodological limitations, this survey allowed documenting mindfulness practice and perceived sustained benefit from MBCT in patients with BD. Participants particularly valued increased awareness that they can influence their own health. Both informal and formal practices, when sustained in the long term, might promote long-lasting changes.

Childhood maltreatment and comorbid anxiety in people with bipolar disorder.

BACKGROUND: Comorbid anxiety disorders and a history of childhood maltreatment are important determinants of outcome in bipolar disorder, but the relationship between these two factors is unclear. METHODS: In 174 outpatients with bipolar disorder, we assessed history of childhood maltreatment with the Childhood Trauma Questionnaire (CTQ) and lifetime diagnosis of anxiety disorders with the M.I.N.I. International Neuropsychiatric Interview. We used ordinary logistic regressions to test associations between childhood maltreatment and the number of comorbid anxiety disorders, controlling for age, sex and the type of bipolar disorder. RESULTS: Ninety (51.7%) participants had no anxiety disorder, 50 (28.7%) had one anxiety disorder and 34 (19.5%) had two or more anxiety disorders. Childhood maltreatment, indexed by a higher CTQ total score, was associated with more lifetime anxiety disorders (OR=1.5; 95% CI=1.01 to 2.14; p=0.04). Of the CTQ subscales, emotional abuse (OR=1.68; 95% CI=1.13 to 2.49; p=0.01) and physical abuse (OR=1.43; 95% CI=1.02 to 2.01; p=0.04) were associated with anxiety disorders. Of the anxiety disorders, panic disorder was most strongly associated with childhood maltreatment (OR=2.27; 95% CI=1.28 to 4.02; p=0.01). LIMITATIONS: The study is limited by a moderate sample size and the retrospective assessment of childhood maltreatment. CONCLUSIONS: Exposure to maltreatment in childhood is associated with comorbid anxiety disorders among individuals living with bipolar disorder. Bipolar disorder with comorbid anxiety may constitute a separate aetiological type with a greater contribution of early environment.

Comorbidity between attention deficit hyperactivity disorder (ADHD) and bipolar disorder in a specialized mood disorders outpatient clinic.

BACKGROUND: Comorbidity between ADHD and Bipolar Disorder (BD) is associated with greater severity of BD. The current study aims at investigating, in a specialized mood disorders clinic, the percentage of comorbid ADHD-BD subjects and assessing the impact of ADHD on the severity of BD. METHODS: Out of 539 mood disorders subjects, the medical records of 138 BD subjects were scrutinized in terms of their clinical and demographic characteristics, and their scores at the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist were logged. Those positively scoring at the ASRS-v1.1 underwent clinical assessment by a senior psychiatrist specialized in ADHD. Comorbid ADHD-BD subjects were then compared with BD sufferers without ADHD. RESULTS: Sixty-three (45.65%) of the participants were screened positive at the ASRS-v1.1. 49 were clinically assessed for the presence of ADHD. Only 27 (55%) received a diagnosis of ADHD. Comorbid ADHD-BD subjects were found to be younger at the onset of BD, showed higher numbers of depressive episodes, more anxiety and substance use disorders, more borderline personality traits and greater cyclothymic temperament. Comorbid BD-ADHD subjects reported more childhood emotional abuse. LIMITATIONS: Some subjects were unreachable and thus not clinically assessed for ADHD. CONCLUSIONS: More than 20% of BD subjects were suffering from ADHD. The comorbidity of the two disorders was associated with worse outcomes, possibly resulting from stressful early-life events. More than 40% of the subjects who scored positively at the ASRS-v1.1 did not suffer from ADHD, which suggests that this scale should be used with caution in BD subjects.
