Abstract
OBJECTIVE Nightmares are dysphoric dreams present in both clinical and non-clinical populations. Physiological activity underlies their emotional reactivity. Therefore, the objective of this study was to investigate the role of interoceptive processes (interoceptive sensibility and nociception) in nightmares in the general population. METHOD 542 French participants were recruited from the general population to complete an online survey. Interoceptive sensibility, nociception, nightmare frequency and nightmare distress were assessed through online scales and questionnaires. Network analysis, regression and mediation analyses were conducted to assess the relationship between these variables. RESULTS The results showed the existence of associations between certain dimensions of interoceptive sensibility, nociception, nightmare frequency and nightmare distress. The regression analysis highlighted the involvement of interoceptive dimensions in predicting the nightmare distress score. Mediation analysis highlighted that nociception was a mediating variable in the relationship between nightmare frequency and nightmare distress. CONCLUSION This study provides initial evidence in favour of the involvement of interoceptive processes in the understanding of nightmares. These results offer a new window of understanding the etiology of nightmares but also present the interest to target interoceptive processes in the management of nightmares.

The ACAMTO study-impact of add-on osteopathic treatment on adolescent patients with anorexia nervosa: study protocol for a randomized controlled trial. Trials 2021; 22:839. [PMID: 34819116 PMCID: PMC8611636 DOI: 10.1186/s13063-021-05810-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 11/09/2021] [Indexed: 11/10/2022] Open
Abstract
Background Anorexia nervosa (AN) mainly affects women (sex ratio 1/10) and most often starts during adolescence. The prognosis of AN remains poor (10% of deaths and high risk of chronicity). Body dissatisfaction, disturbances in recognition and identification of body sensations are some of the key symptoms of AN. However, there is a contrast between this consensual observation of body image disorders in AN, and the relative deficit of specifically targeted body treatments. Our proposal for a body approach specifically dedicated to AN is based on the understanding that posture, breathing, muscle tension and body perception are closely linked to our psychological and emotional state and are therefore disturbed in patients with AN. The purpose of this monocentric randomized controlled trial is to evaluate if a targeted osteopathic protocol treatment for AN in addition to treatment as usual (TAU) is significantly more effective than TAU alone. Methods In total, 72 patients meeting the inclusion criteria will be randomly assigned to one of the two treatment groups: one receiving the specific osteopathic treatment targeted for AN in addition to the TAU (group A) and the other one, receiving TAU only (group B). The patients in group A will receive 5 30-min osteopathic treatment sessions. Soft specific palpatory techniques on the diaphragm, digestive system and cervical region will be performed. The TAU is defined by the multidisciplinary approach recommended by the French health high authority. The primary outcome is the evaluation of interoceptive sensibility and secondary outcomes include clinical and psychopathology-related symptoms with assessment of somatic dysfunctions’ evolution. A qualitative study will also be carried out, applying the Interpretative Phenomenological Analysis method. Patients will be included for a maximum of 14 weeks between the inclusion time and the last evaluation. Discussion If the results of the study are positive (statistically significant efficacy of this osteopathic treatment protocol), the study will provide arguments in favor of osteopathic sessions as a possible non-invasive additional treatment option in the multidisciplinary care approach for patients with AN.

Insula shows abnormal task-evoked and resting-state activity in first-episode drug-naïve generalized anxiety disorder. Depress Anxiety 2020; 37:632-644. [PMID: 32196828 DOI: 10.1002/da.23009] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 02/27/2020] [Accepted: 03/10/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Interoception is associated with neural activity in the insula of healthy humans. On the basis of the somatic symptoms in generalized anxiety disorder (GAD), especially abnormal heartbeat perception, we hypothesized that abnormal activity in the insula was associated with interoceptive awareness in patients with GAD. METHODS We investigated the psychological correlates of interoceptive awareness in a sample of 34 patients with first-onset, drug-naïve GAD and 30 healthy controls (HCs). Furthermore, we compared blood oxygenation level-dependent responses between the two groups during a heartbeat perception task to assess task-evoked activity and its relationship with psychological measures. We also examined between-group differences in insular subregions resting-state functional connectivity (rsFC), and its relationship with anxiety severity. RESULTS Patients with GAD had significantly higher body perception scores than HCs. They also exhibited greater task-evoked activity in the left anterior insula, left posterior insula, and right anterior insula during interoceptive awareness than HCs. Left anterior insula activity was positively correlated with body awareness in patients with GAD, and rsFC between the left anterior insula and left medial prefrontal gyrus was negatively correlated with somatic anxiety severity. CONCLUSIONS Investigating a sample of first-episode, drug-naïve patients, our study demonstrated abnormal interoceptive awareness in patients with GAD and that this was related to abnormal anterior insular activity during both rest and task. These results shed new light on the psychological and neural substrates of somatic symptoms in GAD, and they may serve to establish abnormal interoceptive awareness as a neural and psychological marker of GAD.
