Guidelines for Rigorous and Reproducible Research on Other Specified Feeding or Eating Disorder: Commentary on Dang et al. (2024).

Dang et al.'s review concludes that atypical anorexia nervosa (atypical AN), purging disorder (PD), and night eating syndrome (NES) are clinically significant and severe eating disorders (EDs). However, findings are unlikely to alter their status in future editions of the DSM due to limitations in the literature to date. Guidelines are offered to promote rigorous and reproducible research on other specified feeding or eating disorder OSFED. First, published research diagnostic criteria for atypical AN, PD, and NES should be consistently used to ensure findings across studies reflect the same conditions. Second, operational definitions are recommended for "recurrent" as at least twice within a 3-month period, minimum duration as at least 1 month, and "significant weight loss" as >5% BMI reduction within 1 month. Third, Thomas's and Gydus's trumping scheme for differential diagnosis of OSFED subcategories is endorsed but should prioritize identifying treatment targets based on medical morbidity over mirroring existing diagnostic algorithms. Fourth, a systematic approach for establishing clinical significance is recommended that explicitly notes medical risk associated with malnutrition, purging and nonpurging behaviors, and relevance of marked distress related to binge eating and body image disturbance. Adoption of these guidelines will facilitate necessary research on clinical utility.

Study of Rates and Factors Associated to Psychosomatic Syndromes Assessed Using the Diagnostic Criteria for Psychosomatic Research across Different Clinical Settings

Introduction: Diagnostic Criteria for Psychosomatic Research (DCPR) serve as an instrument for identifying and classifying specific psychosomatic syndromes that are not adequately encompassed in standard nosography. The present study aimed at measuring the prevalence of DCPR syndromes in different clinical settings and exploring factors associated to such diagnoses. Methods: A cross-sectional and nationwide study recruited 6,647 patients in different clinical settings: 306 were diagnosed with fibromyalgia (FM), 333 with irritable bowel syndrome, 1,109 with migraine, 2,550 with coronary heart disease (CHD), and 2,349 with type 2 diabetes (T2D). Participants underwent DCPR diagnostic interview and were assessed for depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder 7-Item Scale), and subjective well-being (World Health Organization-5 Well-Being Index). The PsychoSocial Index was used to evaluate global well-being, stress, and abnormal illness behavior. The prevalence of DCPR diagnoses was calculated, and factors associated to such diagnoses were analyzed by logistic regression. Results: Alexithymia (64.47%), irritable mood (20.55%), and demoralization (15.60%) were the most prevalent psychosomatic syndromes, with demoralization being most common in FM (49.02%). The factors associated to DCPR diagnoses encompassed high anxiety or abnormal illness behavior, and poor well-being. Notably, stress was found to be associated specifically to FM and T2D, with OR of 1.24 (95% CI: 1.06–1.46) and 1.26 (95% CI: 1.18–1.36), respectively. Conclusion: DCPR is a clinically helpful complementary assessment tool in need of being widely implemented in clinical settings in order to have a comprehensive picture of the patients.

Refining Research Diagnostic Criteria for Catatonia Among Delirium, Medical, Affective, and Psychosis Patient Groups.

The authors proposed catatonia diagnostic criteria that require the presence of three neuropsychiatric symptom clusters, rated over 24 hours; this system differs from other symptom clustering proposals and is intended to increase diagnostic rigor over Bush-Francis Catatonia Rating Scale (BFCRS) or DSM-5 criteria. By applying new BFCRS item score thresholds, symptoms were clustered into three categories to comprise the Research Diagnostic Criteria for Catatonia (RDCC): akinesia (criterion A), unusual motor signs (criterion B), and behavioral signs (criterion C). RDCC symptom clusters were analyzed in four prospectively evaluated patient groups (delirium, medical, affective, and psychosis) (N=341). Use of the RDCC, compared with the DSM-5-TR and BFCRS, resulted in far fewer diagnoses of catatonia in the four patient groups: medical, N=1 out of 42 (2%); affective, N=1 out of 45 (2%); psychosis, N=3 out of 53 (6%); and delirium, N=0 out of 201. Permutations of the RDCC with more relaxed criteria were assessed, requiring either symptom thresholds or numbers of symptoms to meet criteria, resulting in catatonia rate gradations between those obtained with the RDCC and those obtained with current systems. The Cochrane Q test found that the DSM-5-TR was not dissimilar to the RDCC, if fulfilling numerical thresholds for criteria A-C, although any level of symptom severity was allowed. Confirmatory factor analysis with three goodness-of-fit indexes validated the RDCC. The RDCC requires akinetic symptoms on the basis of literature demonstrating their high BFCRS prevalence and exploratory factor analysis co-loadings, plus symptoms from unusual motor and behavioral signs. Compared with current lenient diagnostic approaches, having the symptoms required by the RDCC produced lower catatonia rates in the psychosis, affective, and medical groups and revealed no patients with catatonia in the delirium group. Subdividing DSM-5-TR symptoms into several different criteria may improve diagnosis. RDCC symptom clusters are both research data-based and amenable to further research for validation.

Impact of baseline body mass index on antidepressant response: A study in newly diagnosed patients at a tertiary care center in Kolkata

Background: Depression, affecting 350 million globally, poses significant morbidity and mortality. The correlation between major depressive disorder (MDD) and obesity is noted, with studies indicating poorer treatment outcomes among obese individuals. Measuring weight and body mass index (BMI) could aid in predicting depression treatment outcomes, influencing drug efficacy due to their ease of measurement, amid the shared public health burden of MDD and obesity. Aims and Objectives: The aims and objectives of the study are to evaluate baseline BMI’s impact on antidepressant response in newly diagnosed outpatient department (OPD) patients at a tertiary care center. Materials and Methods: This longitudinal observational study was conducted with OPD patients at a tertiary care center, aged 18–65 years with newly diagnosed MDD. Assessment tools included the Diagnostic Criteria for Research accompanying the ICD-10, the Hamilton Rating Scale for Depression, and physical measurement devices. Sample size determination considered BMI groups: Normal to underweight (N1=120), overweight (N2=120), and obese (N3=70). The methodology involved patient history, examination, and follow-up assessments after 6 weeks, analyzing antidepressant response statistically. Results: Obese patients exhibited reduced treatment response rates compared to normal and overweight counterparts. Responders had lower mean BMI. Gender disparities in obesity prevalence were noted. Limitations: The study’s limitations include a small sample size of 310 cases, single-center design, and potential selection bias in a tertiary care setting. Conclusion: The findings underscore the complex relationship between BMI, depression severity, and treatment response. Obese individuals demonstrated higher initial depression scores and poorer treatment response, echoing previous research. The study highlights the need for personalized treatment approaches that consider individual BMI levels to optimize depression management strategies effectively.

Characterizing Neurobehavioral Dysregulation Among Former American Football Players: Findings From the DIAGNOSE CTE Research Project.

Neurobehavioral dysregulation (NBD), a core clinical feature of traumatic encephalopathy syndrome, encompasses neuropsychiatric symptoms reported among individuals with a history of repetitive head impact exposure, including contact sport athletes. The objective of this study was to examine the construct and subconstructs of NBD through a series of factor and cluster analyses. Six clinician-scientists selected self-report questionnaire items relevant to NBD from seven available neuropsychiatric scales through a blinded voting process. These items were subjected to confirmatory factor analyses in a sample of 178 former college and professional American football players and 60 asymptomatic individuals without a history of repetitive head impact exposure. All participants were enrolled in the Diagnostics, Imaging, and Genetics Network for the Objective Study and Evaluation of Chronic Traumatic Encephalopathy Research Project. Factor scores were generated on the basis of the optimal expert-informed model for NBD. Construct validity was assessed with neuropsychiatric scales not included in generation of the factor scores. Cluster analyses with NBD factor scores were used to examine symptom profiles. Factor analyses confirmed that NBD was composed of four subconstructs: explosivity, emotional dyscontrol, impulsivity, and affective lability. Cluster analyses indicated four distinct symptom profiles of NBD in this group of former football players: asymptomatic (N=80, 45%), short fuse (N=33, 19%), high affective lability (N=34, 19%), and high NBD (N=31, 17%). These findings characterize NBD as a multifaceted clinical construct with a heterogeneous presentation, providing a foundation for empirical work on the diagnostic criteria for traumatic encephalopathy syndrome and research on the neurobiological underpinnings of NBD.

Association between obstructive sleep apnea and temporomandibular disorders: A meta-analysis.

Obstructive sleep apnea (OSA) is a very common condition in patients with temporomandibular disorders (TMD). However, there is little evidence of a connection between them. The aim of this systematic review and meta-analysis is to assess the association between OSA and TMD in adult population. Case-control, cross-sectional and cohort studies on the association between TMD and OSA were searched in the EMBASE, LILACS, LIVIVO, PubMed/MEDLINE, Scopus, Web of Science, Google Scholar, Open Grey and Pro Quest databases. TMD should be assessed using Research Diagnostic Criteria (RDC/TMD) or Diagnostic Criteria (DC/TMD) and OSA using polysomnography (PSG) and/or a validated questionnaire. The risk of bias was evaluated using the Joanna Briggs Institute Critical Assessment Checklists; and an association meta-analysis was performed. The effect measure included the odds ratio (OR) in dichotomous variables and a 95% confidence interval (CI). Certainty of evidence was determined by analysing groups using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Out of the 1024 articles screened, 7 met the inclusion criteria for the qualitative synthesis, and 6 for quantitative analysis. All articles were classified at low risk of bias. A positive association with OSA was found in patients with TMD (OR = 2.61; 95% CI = 2.31, 2.95). A significant association was also found irrespective to the OSA diagnostic methods applied (for studies using PSG + validated questionnaires: OR = 2.74; 95% CI = 2.11, 3.57; for studies using validated questionnaires only: OR = 2.55; 95% CI = 2.22, 2.92). GRADE was moderate. Patients with TMD presented a significant association with OSA regardless of the OSA diagnostic method (PSG and/or validated questionnaires). OSA screening should be part of the TMD examination routine. Furthermore, due to the different OSA assessment methods used and the small number of studies included, there is a need to include a larger number of studies using PSG to better elucidate this association.

Lifespan of Splints in a Sample of German Soldiers Hospitalised with Post-traumatic Stress Disorder (PTSD) in Combination with Sleep Bruxism and Painful Temporomandibular Disorder (TMD).

This cross-sectional longitudinal observational study aimed to clarify the question of whether painful temporomandibular disorders (TMD) in psychiatrically confirmed patients hospitalised for post-traumatic stress disorder (PTSD) therapy after using splint therapy (ST) show long-term therapeutic effects in the case of functional disorders. One hundred fifty-three (153) inpatients (123 male and 20 female soldiers, age 35.8 ± 9.2 years, 26.6 ± 2.2 teeth) with confirmed PTSD (Impact of Event Scale - Revised ≥33), grade 3 to 4 chronic pain according to von Korff's Chronic Pain Scale and the research diagnostic criteria of painful TMD (RDC-TMD) were recorded. All participants received a maxillary occlusal splint that was worn at night. Control check-ups of the therapeutic effect of the splint were conducted for up to 9 years during psychiatric follow-ups. TMD pain worsened in 22 (14.4%) patients within the first 6 weeks and led to the removal of the splint. The pain intensity (PI) at BL was reported to be a mean of VAS 7.7 ± 1.1. Six weeks after ST (n = 131), the average PI was recorded as VAS 2.6 ± 1.3. Based on the last examination date of all subjects, the average PI was recorded as 0.7 ± 0.9. Seventy-two (72) patients used a second stabilisation splint in the maxilla after 14.4 ± 15.7 months, and 38 patients used between 3 and 8 splints during their psychiatric and dental treatment time (33.7 ± 29.8 months). The presented data shows that therapeutic pain reduction remained valid in the long term despite continued PTSD. The lifespan of a splint seems to be dependent on individual factors. Long-term splint therapy appears to be accepted by the majority of patients with PTSD and painful TMD.

Stigma and its Correlation in Patients with Schizophrenia

ABSTRACT The aim of the present study was to assess the stigma in patients with schizophrenia attending a tertiary referral government hospital. This was a cross-sectional research involving 60 schizophrenia patients at a government tertiary referral hospital. ICD-10 research diagnostic criteria were used for mental assessment. Statistics were analyzed using relevant tests. Of the 30 males, 21 (70%) experienced moderate stigma, two (6.67%) had mild stigma, and seven (23.33%) had severe stigma. The 30 females got 20 (66.67%) moderate ratings, one (3.33%) got a light grade, and nine (30%) had severe stigma grades associated with stigma disclosure. Twenty of 30 males (66.67%) reported moderate stigma, eight (26.67%) reported mild stigma, and two (6.66%) had severe stigma. With respect to positive stigma, 25 (83.33%) of 30 females exhibited moderate stigma. Also, four (13.33%) girls exhibited moderate stigma and one (3.33%) had severe stigma. Significant proportion of patients with schizophrenia experience stigma and stigma is associated with lower level of functioning. Better knowledge about illness is associated with a lower level of stigma.

Neurobehavioral Changes Resulting from Recurrent Head Injuries

In recent years, there has been a significant focus on the potential link between traumatic brain injury (TBI) due to recurrent head injuries (RHI) and the development of Traumatic Encephalopathy Syndrome (TES), whichcould lead to chronic traumatic encephalopathy (CTE). Recurrent head injuries may cause neurobehavioral changes, significantly impacting an individual's cognitive and behavioral functioning. These changes can lead to various challenges, including difficulties in social interactions, work performance, and overall quality of life. CTE is a progressive disease characterized by Axonal injury tau neurofibrillary tangles (NFTs) and, in some cases, transactive response DNA binding protein 43 (TDP43). This case report discusses a patient who experienced auditory verbal hallucinations (AVH) and cognitive symptoms with behavioral issues due to recurrent RHI. The aim is to investigate this presentation further to examine the relationship between recurrent head injury (RHI) and chronic traumatic encephalopathy (CTE) and to understand the psychological impact of physical brain trauma. A 43-year-old white male with a history of RHI from multiple sports-related concussions was admitted to the psychiatric unit for cognitive difficulties with auditory verbal hallucinations and associated mood symptoms for the past four years, impacting both his sleep and productivity at work. This article will discuss the different types of auditory hallucinations seen in patients with RHI and CTE, along with exploring the evidence to support our determination due to repeated RHI, which led to symptomatology suggestive of CTE. Differential diagnoses will be considered, and evidence is provided to rule them out based on the patient's history. This case report underscores the diagnostic challenges associated with CTE, which can manifest with a spectrum of psychiatric symptoms encompassing mood, cognition, and behavior. The medical diagnosis of Chronic Traumatic Encephalopathy (CTE) in living patients is still a challenge, as effective biomarkers for this condition have yet to be discovered. Although research diagnostic criteria have been proposed, there is no definitive way to diagnose CTE in living patients. Therefore, further investigation is necessary to develop accurate diagnostic tools and effective treatments for CTE.

Pain catastrophizing in Temporomandibular disorders patients

Background: Pain catastrophizing can be defined as a series of negative thoughts about an actual or potential painful experience. Temporomandibular dysfunction (TMD) is a collective term for a painful musculoskeletal syndrome, temporomandibular joint and the associated structures. Aim: Evaluate the level of pain catastrophizing in individuals with TMD. Methods: a total of 40 participants were evaluated and divided into two groups: a control group with 20 individuals without TMD and an experimental group with 20 individuals with TMD. Participants with TMD were evaluated through medical history and clinical examination considering their chief complaint and followed the Research Diagnostic Criteria for Temporomandibular Disorders. The Pain Catastrophizing Scale was applied to all participants in both groups. Results: Although women represented the largest group with TMD, they did not present higher levels of pain catastrophizing compared to men. Age was not statistically relevant, which contradicts some previously published studies. The group with TMD had a higher pain catastrophizing index (p ≤ 0.001), but no TMD subtype was related to this index. Rumination, magnification, and hopelessness were relevant in this study and showed high correlation with TMD. Conclusions: patients with TMD presented higher scores of pain catastrophizing than healthy individuals.

Evaluation of the effect of different kinds of treatment modalities for temporomandibular joint pain and its relevance to chronic cervical pain: A randomized controlled trial.

The aim of this study was to evaluate the effect of different treatment modalities for temporomandibular joint (TMJ) pain and their relevance to chronic cervical pain after 12 months. This was a randomized controlled trial. Forty-eight participants with chronic cervical and TMJ pain were selected using research diagnostic criteria and randomized into four groups (n = 12), which included control, soft splints, transcutaneous electrical nerve stimulation (TENS), and low-level laser (LLL). The cervical and TMJ pain was recorded using visual analog scale (VAS) scores at baseline, 3 months, 6 months, and 12 months. Occlusal equilibration was done for all groups except for the control. The mean pain scores were statistically analyzed using one-way analysis of variance and posthoc test. The mean VAS scores in TMJ pain patients between the four groups at baseline and at final follow-up were 7.27 ± 1.29 in Group 1, 7.53 ± 0.70 in Group 2, 7.76 ± 0.80 in Group 3, and 7.61 ± 0.61 in Group 4. The mean difference between Groups 1 and 3, Groups 1 and 4, and Groups 2 and 3 was statistically significant (P < 0.00). Pearson correlation test yielded a mild and negative correlation between TMJ and cervical pain. TENS and LLL were found to be equally effective in reducing pain in the jaw joint region, followed by soft splints, and there was no correlation between TMJ and cervical pain.

Internalized Stigma among Persons with Schizophrenia: A Study from Tertiary Care Center in the Northeastern Part of India

Abstract Background: Stigma relating to mental illness has mostly been studied in communities and families. Less research has been conducted in India to understand the current subjective experience of persons with mental illness in the tertiary care hospital setting in India. Aim and Objectives: This study aimed to assess the extent of internalized stigma among persons and to see the association between self-stigma, self-esteem, insight, and adherence. Methodology: The study used a cross-sectional design. The present study was conducted in the Outpatient Department of LGB Regional Institute of Mental Health, Tezpur, Assam. For the present study, 200 persons with schizophrenia were selected. Participants of this study were persons with a clinical diagnosis of schizophrenia according to the International Classification of Diseases-10 Diagnostic Criteria for Research. Sociodemographic and clinical data sheet, Brief Psychiatric Rating Scale, the Internalized Stigma of Mental Illness Scale, Morisky Adherence Scale, and Rosenberg Self-Esteem Scale were administered. The collected data were analyzed using descriptive and inferential statistics in Statistical Package for Social Science (SPSS) 21 version. Results: The findings show that 45% of the participants were having moderate internalized stigma and 21% of the participants were having severe internalized stigma. Self-Esteem Scale (B = −341, t = −2.940, P = 005), medication adherence (B = −701, t = −9.832, P = 000), and insight (B = −711, t = −6.496, P = 000) contributed significantly to the prediction of internalized stigma among persons with schizophrenia (F [3,63] =58.712, P = 000) accounting for 85.8% variance. Conclusion: The findings confirm that self-esteem, medication adherence, and insight contributed significantly to the prediction of internalized stigma among persons with schizophrenia.

EFFECT OF USING A RELAXATION SPLINT ON REDUCING CHRONIC NECK PAIN

Background: Approximately 80% of patients seeking dental care exhibit parafunctional manifestations of the temporomandibular joint (TMJ), while approximately 70% of patients with TMJ dysfunction experience pain in the cervical spine. It is noteworthy that neck pain is a socially significant phenomenon, as this condition can lead to a substantial decline in the patient's quality of life and disability.&#x0D; Aim: To determine the effect of using a relaxation mouthguard in patients with TMJ dysfunction on reducing chronic neck pain.&#x0D; Materials and methods: The study involved 16 individuals with manifestations of TMJ dysfunction, who were divided into 2 groups. The diagnosis was based on a questionnaire following the research diagnostic criteria for TMD, VAS, and the Oswestry cervical scale. Questionnaires and other examinations were conducted on all patients four times (before treatment, on days 8, 15, and 23 after treatment). Cervical spine mobility was assessed in all patients, and mandibular axiography was performed. Patients in the experimental group, comprising 8 individuals, were fitted with individual relaxation splints and prescribed manual massage of the masticatory and cervical muscles. Patients in the control group, also consisting of 8 patients, were instructed to perform manual massage of the masticatory and cervical muscles.&#x0D; Results: Patients in both study groups demonstrated a reduction in clinical symptoms. According to the study data, the reduction of pain in the experimental group from the beginning to the end of treatment was 62.86% (p &lt; 0.001) of the initial value, whereas in the control group, it was 13.75% (p &lt; 0.001). There was an increase in mobility of the cervical spine in both study groups (p &lt; 0.001). The index of cervical spine disability in the experimental group improved by 225% compared to the control group.&#x0D; Conclusions: The use of a relaxation mouthguard in patients with TMJ dysfunction and existing neck pain symptoms can alleviate chronic pain manifestations in the cervical spine.

Cannabidiol Intervention for Muscular Tension, Pain, and Sleep Bruxism Intensity-A Randomized, Double-Blind Clinical Trial.

Background: Temporomandibular disorders (TMDs) are the most prevalent non-dental pain issues in the maxillofacial region. Despite advancements, diagnosing and managing TMDs continues to pose challenges. This study aimed to assess the efficacy of cannabidiol (CBD) formulations, with different concentrations, in patients experiencing sleep bruxism and muscle-related TMDs, with a particular emphasis on their myorelaxant, pain-relieving, and bruxism-reducing properties. Methods: The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMDs) was utilized as the diagnostic framework. Sixty patients completed the study, which followed a parallel-group, three-arm, randomized, double-blind clinical trial design, with a 1:1:1 allocation ratio across three groups: 1a, 1b, and 2. Groups 1a and 1b received CBD formulations at concentrations of 10% and 5%, respectively, while Group 2 received a placebo formulation. The trial consisted of four main visits, namely screening, baseline, first follow-up after 14 days, and second follow-up after 30 days, during which surface electromyography (sEMG), the visual analogue scale (VAS) for pain assessment, and Bruxoff examinations were conducted. Results: The reduction in pain, as measured by the visual analogue scale (VAS), among patients using the 10% CBD formulation was 57.4% (p < 0.05), accompanied by a decrease in sEMG activity by 42.1% (p < 0.05). Conversely, individuals using the 5% CBD formulation experienced a 40.8% (p < 0.05) decrease in pain. Regarding the decrease in the sleep bruxism index, users of the 10% CBD formulation saw the highest reduction of 51% (p < 0.05). These findings underscore the efficacy of the proposed treatment in both experimental groups, with a notable advantage observed in Group 1a. Conversely, the outcomes of the selected variables for the control group did not exhibit significant differences throughout the study. Conclusions: The intraoral use of CBD formulations in patients with TMDs have proven to be a successful treatment for reducing pain, muscle tension, and bruxing activity in individuals with sleep bruxism and muscle-related TMDs. Specifically, a concentration of 10% CBD has demonstrated superior results compared to 5% CBD.

Etiologic Factors of Temporomandibular Disorders: A Systematic Review of Literature Containing Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) from 2018 to 2022.

This study aims to conduct a systematic analysis of literature published between 1 January 2018 and 1 September 2022, exploring factors influencing the progression or development of temporomandibular disorders (TMD), diagnosed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) or Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Three electronic databases were reviewed to identify papers that examined TMD factors using DC/TMD or RDC/TMD. Inclusion criteria encompassed original research published in English between 1 January 2018 and 1 October 2022, online, and complete DC/TMD or RDC/TMD studies on human participants aged 18 or older. Two authors independently assessed the risk of bias using The Joanna Briggs Institute (JBI) Analytical cross-sectional studies' Critical Appraisal Tool. Of 1478 articles, 11 were included. The studies revealed strong associations between TMD and factors such as female, poor sleep quality, depression, oral parafunction, anxiety, somatization, and anatomical features. However, variables such as education, living conditions, socioeconomic status, marital status, chronic pain, and stress did not exhibit statistically significant correlations. Based on the obtained data, it can be concluded that the causes of TMD are largely related to psychological factors, which supports the biopsychosocial theory of the disorder.

Clinical Psychology in the Era of Research Diagnostic Criteria (RDoC): Reconciling Individually-Focused Practice with a Broader Biopsychosocial Context.

There is growing consensus that diagnostic labels are insufficient to describe the individual child's psychiatric profile, much less inform the precise combination of interventions that will minimize the impact of risk and/or bolster protective factors over the course of a particular child's development. Moreover, investigations of neurobiological and genetic mechanisms associated with psychopathology have revealed considerable cross-diagnostic overlap, undermining the validity of models that propose a 1:1 relationship between risk and psychiatric disorder. Accordingly, recent publications have advocated for neurodevelopmental models that utilize trait-based measurement, as well as increased emphasis on integration of biological and experiential mechanisms. Despite an expanding body of literature supporting this conceptual shift, the practical implications remain unclear. In this special issue, we compile a collection of novel empirical research papers and reviews that build on the trans-diagnostic principles of the RDoC framework.

Prevalence of mild behavioural impairment and its association with cognitive and functional impairment in normal cognition, mild cognitive impairment, and mild Alzheimer's dementia.

Mild behavioural impairment (MBI) is an emergent and persistent neuropsychiatric symptom (NPS) in subjects aged 50 and older who are at risk for cognitive decline. We examined the prevalence of MBI across the spectrum from cognitively normal (CN), mild cognitive impairment (MCI), to dementia, and further investigated the association between the MBI domain and cognitive and functional impairment. MBI was assessed in 2337 elderly patients in the Alzheimer's Disease Neuroimaging Initiative database (mean age, 73.04 years; 52.8% male). Among the subjects, 868 (37.1%) had normal cognition, 1066 (45.6%) had MCI, and 403 (17.2%) had mild Alzheimer's dementia (AD). MBI was evaluated in accordance with the Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment diagnostic criteria for MBI, utilising the Neuropsychiatric Inventory. We compared the prevalence of the MBI domain with CN using multinominal logistic regression analysis and further quantified the magnitude of the association between MCI/AD and the MBI domains by calculating the population attributable risk (PAR). We assessed the association between the MBI domains and cognitive and functional impairment using simultaneous linear regression analysis. The most common MBI domains in each diagnostic group were affective dysregulation followed by impulse dyscontrol, decreased motivation, social inappropriateness, and abnormal perception or thought content. The PARs for MBI domains in subjects with MCI or AD were respectively: 16.60% and 24.34% for affective dysregulation; 3.72% and 18.06% for impulse dyscontrol; 4.78% and 14.13% for decreased motivation, 1.91% and 2.29% for social inappropriateness; and 0.68% and 3.85% for abnormal perception or thought content. All MBI domains except for social inappropriateness were significantly associated with a higher 11-item Alzheimer's Disease Assessment Scale-Cognitive Subscale total score. All MBI domains were significantly associated with a higher Functional Activities Questionnaire total score. Our findings show that MBI is highly prevalent across subjects with CN, MCI, and AD and is associated with cognitive and functional decline. MBI could be a crucial clinical phenotype relevant to the risk of cognitive and functional impairment, and provides a useful dimension pertinent to diagnostic approaches.

Whiplash trauma did not predict jaw pain after 2 years: an explorative study

ObjectivesTo explore predictive factors for the development and maintenance of jaw pain over a 2-year period.MethodsOne hundred nineteen cases (73 women) and 104 controls (59 women), mean age 34.9 years (SD 13.9), attended baseline and 2-year follow-up examinations. The whiplash cases visited the emergency department at Umeå University Hospital, Sweden, with neck pain within 72 h following a car accident, and baseline questionnaires were answered within a month after trauma. Controls were recruited via advertising. Inclusion criteria were age 18–70 years, living in Umeå municipality and Swedish speaking. The exclusion criterion was neck fracture for cases and a previous neck trauma for controls. Validated questionnaires recommended in the standardized Research Diagnostic Criteria for temporomandibular disorders were used. Jaw pain was assessed by two validated screening questions answered with “yes” or “no.” A logistic regression analysis was used to predict the outcome variable jaw pain (yes/no) after 2 years.ResultsWhiplash trauma did not increase the odds of development of jaw pain over a 2-year period (OR 1.97, 95% CI 0.53–7.38). However, non-specific physical symptoms (OR 8.56, 95% CI 1.08–67.67) and female gender (OR 4.89, 95% CI 1.09–22.02) did increase the odds for jaw pain after 2 years.ConclusionThe development and maintenance of jaw pain after whiplash trauma are primarily not related to the trauma itself, but more associated with physical symptoms.Clinical relevanceThe development of jaw pain in connection with a whiplash trauma needs to be seen in a biopsychosocial perspective, and early assessment is recommended.

Self-reported bruxism in patients with post-traumatic stress disorder.

The present study aimed to investigate the association between self-reported awake/sleep bruxism, and orofacial pain with post-traumatic stress disorder (PTSD). 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. 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. 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. 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.
