Abstract
Introduction The link between anxiety disorders and joint hypermobility syndrome (now under hypermobility spectrum disorders, which include hypermobile Ehlers-Danlos syndrome) has been widely replicated over the past 30 years and has grown beyond the initial nosological limits. To integrate clinical and research progress in this field, a new neuroconnective endophenotype (NE) and its corresponding instrument, the Neuroconnective Endophenotype Questionnaire (NEQ), have been developed. This new clinical construct, created with the active participation of patients, includes both somatic and psychological dimensions and symptoms and resilience items. Methods The NE includes five dimensions: (1) sensorial sensitivity, (2) body signs and symptoms, (3) somatic conditions, (4) polar behavioral strategies, and (5) psychological and psychopathological dimensions. The NEQ information is collected through four self-administered questionnaires (sensorial sensitivity, body signs and symptoms, polar behavioral strategies, and psychological characteristics) and a structured diagnostic part that should be completed by a trained observer. This hetero-administered part incorporates (a) psychiatric diagnoses (using structured criteria, e.g., MINI), (b) somatic disorders diagnosis, using structured criteria, and (c) assessment of joint hypermobility criteria. Results In a sample of 36 anxiety cases with 36 matched controls, the NEQ obtained high scores for test-retest, inter-rater reliability, and internal consistency. As for predictive validity, cases and controls significantly differed in all five dimensions and hypermobility measurements. Discussion We can conclude that the NEQ has achieved acceptable reliability and validity values and, therefore, is ready to be used and tested in different samples. This original and consistent construct including somatic and mental items may improve clinical specificity, the search for more comprehensive therapies, and their genetic and neuroimaging bases.

The psychological burden associated with Ehlers-Danlos syndromes: a systematic review. J Osteopath Med 2022; 122:381-392. [PMID: 35420002 DOI: 10.1515/jom-2021-0267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Accepted: 03/16/2022] [Indexed: 11/15/2022]
Abstract
CONTEXT Ehlers-Danlos syndromes (EDS) are disorders of connective tissue that lead to a wide range of clinical presentations. While we are beginning to understand the association between EDS and psychological manifestations, it is critical that we further elucidate the relationship between the two. Understanding the correlation between EDS and mental health will better ensure swift diagnosis and effective treatment for patients. OBJECTIVES This study aims to systematically examine and report the prevalence of psychiatric disorders in the EDS population. METHODS The PubMed database was searched on June 14, 2021 for articles published from January 2011 to June 2021. We included original, evidence-based, peer-reviewed journal articles in English that reported information on psychiatric disorders among EDS patients. Psychiatric disorders and psychological conditions were limited to those included in the "psychology" and "mental disorders" Medical Subject Headings (MeSH) search terms defined by the National Library of Medicine. Publications identified utilizing this search strategy by M.K. were imported into the Covidence system, where they first underwent a title and abstract screening process by three independent reviewers (M.K., K.L., H.G.). During the full-text review, two independent reviewers read the full text of the questionable articles to assess their eligibility for inclusion. Studies were excluded if they did not meet our target objective or if they were not in English or if they were opinion pieces, conference abstracts, or review articles. Data were extracted from the shortlisted studies by reviewers. During the data extraction phase, the quality and risk of publication bias were assessed by two independent reviewers utilizing the National Institutes of Health (NIH) Study Quality Assessment Tools. Any disagreements in study selection, data extraction, or quality assessment were adjudicated via discussion between the two reviewers, utilizing a third reviewer as a decider if necessary. RESULTS Out of 73 articles identified, there were no duplicates. A total of 73 records were screened, but only 40 articles were assessed in full text for eligibility. A total of 23 articles were ultimately included, which collectively discussed 12,298 participants. Ten (43.5%) of the included studies were cross-sectional in design, three (13.0%) were case reports, and three (13.0%) were retrospective chart reviews. The remaining seven (30.4%) articles were either case-control, cohort, qualitative, controlled observational, or validation studies. Twelve (52.2%) of the studies reported data on depression disorders, six of which reported prevalence data. Nine (39.1%) of the studies reported data on anxiety disorders, five of which reported prevalence data. Studies that reported nonprevalence data presented odds-ratio, mean scores on psychiatric evaluations, and other correlation statistics. Psychiatric disorders that were most reported in these articles were mood disorders (n=11), anxiety disorders (n=9), and neurodevelopmental disorders (n=7). Although the reports varied, the highest psychiatric prevalence reports in EDS patients involved language disorders (63.2%), attention-deficit/hyperactivity disorder (ADHD) (52.4%), anxiety (51.2%), learning disabilities (42.4%), and depression (30.2%). CONCLUSIONS Although mood disorders were cited in more articles, the highest reported prevalence was for language disorders and ADHD. This discrepancy highlights the importance of performing more research to better understand the relationship between EDS and psychiatric disorders.

Functional somatic syndromes and joint hypermobility: A systematic review and meta-analysis. J Psychosom Res 2021; 148:110556. [PMID: 34237584 DOI: 10.1016/j.jpsychores.2021.110556] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Revised: 06/17/2021] [Accepted: 06/18/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE There have been multiple reports of increased joint hypermobility (JH) in functional somatic syndromes (FSS). We sought to evaluate the evidence for an association. METHODS A systematic search of the databases Medline and PsycINFO was conducted to identify all controlled studies from inception to February 2020 measuring the association of an FSS and JH. Records were identified and screened, and full-text articles assessed for eligibility by two independent authors. Meta-analysis was performed using random-effects modelling with the DerSimonian and Laird method. RESULTS We found 220 studies initially, which yielded 11 studies for inclusion in the qualitative review and 10 in the quantitative analysis - 5 studies on fibromyalgia, 3 on chronic fatigue syndrome and 3 on functional gastrointestinal disorder. Nine of the 11 studies found increased rates of JH in FSS compared to controls, though most studies were fair to poor in quality. Meta-analysis showed a weighted summary effect odds ratio of 3.27 (95% CI: 1.83, 5.84; p < 0.001) of JH in FSS, suggesting greater odds of FSS in individuals with JH than in those without. CONCLUSIONS There is some evidence for an association between FSS and JH, but this is limited by the generally poor quality of studies and the narrow range of FSS studied. Better research is needed to confirm these findings as well as evaluate causation using prospective cohort studies.

Abstract
Ehlers-Danlos syndrome (EDS) comprises a series of rare hereditary connective tissue diseases characterized by joint hypermobility, joint dislocation, and hyperextensibility of the skin, as well as cardiovascular involvement. EDS is often associated with chronic widespread physical pain, which can lead to psychological pain. Poor awareness and limited diagnosis of EDS and related symptoms result in decreased self-esteem and confusion regarding physical sensation. Furthermore, EDS imposes substantial psychological burden on patients due to exercise restriction, scars, keloids, and subcutaneous fat accumulation on the extremities, which leads to parental overprotection and bullying experiences from other children at school age. Recent large-scale studies have suggested that patients with EDS have a higher risk of mood disorders than the general population. Other cohort studies indicated high prevalence of anorexia nervosa, addiction, obsessive compulsive disorder, and anxiety disorder were found in patients with EDS. Case reports instead indicated that some psychiatric disorders were secondary symptoms due to physical problems from EDS. Therefore, psychiatrists must be more knowledgeable and proactive about EDS in their practice. We review the previous case reports and literature for patients with EDS, along with our own case of complicated psychiatric problems, which are strongly related to early stressful situations through childhood and adolescence. This is to aid general psychiatrists in the discussion of appropriate medical management in such infrequent, yet challenging conditions.

Pelvic Girdle Pain, Hypermobility Spectrum Disorder and Hypermobility-Type Ehlers-Danlos Syndrome: A Narrative Literature Review. J Clin Med 2020; 9:jcm9123992. [PMID: 33317183 PMCID: PMC7764306 DOI: 10.3390/jcm9123992] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 11/27/2020] [Accepted: 12/04/2020] [Indexed: 01/04/2023] Open
Abstract
Pelvic girdle pain (PGP) refers specifically to musculoskeletal pain localised to the pelvic ring and can be present at its anterior and/or posterior aspects. Causes such as trauma, infection and pregnancy have been well-established, while patients with hypermobile joints are at greater risk of developing PGP. Research exploring this association is limited and of varying quality. In the present study we report on the incidence, pathophysiology, diagnostic and treatment modalities for PGP in patients suffering from Hypermobility Spectrum Disorder (HSD) and Hypermobility-Type Ehlers-Danlos Syndrome (hEDS). Recommendations are made for clinical practice by elaborating on screening, diagnosis and management of such patients to provide a holistic approach to their care. It appears that this cohort of patients are at greater risk particularly of mental health issues. Moreover over, they may require a multidisciplinary approach for their management. Ongoing research is still required to expand our understanding of the relationship between PGP, HSD and hEDS by appropriately diagnosing patients using the latest updated terminologies and by conducting randomised control trials to compare outcomes of interventions using standardised patient reported outcome measures.

Abstract
There is a well-established relationship between joint hypermobility and anxiety in humans, that has not previously been investigated in other species. A population of 5575 assistance dogs were scored for both hip hypermobility and 13 behaviour characteristics using previously validated methods. Our results suggest a positive association between hip joint hypermobility and emotional arousal in domestic dogs, which parallel results found in people.

Abstract
Objectives: To describe a therapeutic education program for patients with hypermobile Ehlers-Danlos syndrome, called PrEduSED and to evaluate its feasibility and efficiency in terms of satisfaction and impact on disease management in daily life. Methods: Prospective observational study. Evaluation before, after and 6 months after PrEduSED, consisted in: CSQ-F, SF-12, HAD, QIC, FIS, Zarit, Quiz and Vignettes (knowledge and skills about the disease), satisfaction questionnaire, Goal Attainment Scales. Results: Nineteen (19) patients (89% women, mean age: 39.2) were included and 9 relatives (78% men, mean age: 44.1). Participants were generally highly satisfied with the content and the organization of PrEduSED. Knowledge about the EDS and skills significantly improved (p < 0.001 for patients, p = 0.016 for relatives). QIC score improved significantly (p = 0.047) and FIS score also for the relationships domain (p = 0.05). At the end of the program, 69% of participants thought they had achieved their goals (mainly about acquiring knowledge and managing their treatment) beyond what they had hoped for; at 6 months, 54% felt they had achieved them beyond what they hoped for. Conclusions: Real success of PrEduSED for patients with hypermobile EDS in terms of recognition, satisfaction, increase of knowledge about the disease and adaptative skills.

Pain and gastrointestinal dysfunction are significant associations with psychiatric disorders in patients with Ehlers-Danlos syndrome and hypermobility spectrum disorders: a retrospective study. Rheumatol Int 2019; 39:1241-1248. [PMID: 30923956 DOI: 10.1007/s00296-019-04293-w] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 03/20/2019] [Indexed: 12/20/2022]
Abstract
In this retrospective study, we investigate the frequency and types of psychiatric disorders and their relationship to systemic manifestations in a cohort of 391 Ehlers-Danlos syndromes (EDS) and hypermobility spectrum disorder (HSD) patients based on the current 2017 International Classification of EDS diagnostic criteria. A detailed, systematic retrospective chart review was undertaken for patients assessed for HSD or EDS at two Canadian health centres. Patients were diagnosed according to the Villefranche criteria and reclassified for this study according to the 2017 International Classification of EDS. Data validation and statistical analyses were conducted. Psychiatric disorders were very common, with 49.4% of the total cohort affected; 28.9% reported multiple psychiatric diagnoses. Mood (34.5%) and somatoform (28.6%) disorders were most common. Interestingly, attention-deficit/hyperactivity disorder (ADHD) was significantly enriched in the HSD, but not EDS cohort (p = 0.0002, 95% CI 3.48-9.00) compared to the general population. There were no differences in the systemic associations with having psychiatric manifestations in the HSD compared to the EDS subsets. Muscle/body pain (OR 1.99) and gastrointestinal dysfunction (OR 2.07) were significantly associated with having mood disorders, and gastrointestinal dysfunction (OR 2.61) and nerve-related pain (OR 3.27) were associated with having somatoform disorders across the cohort. The common systemic associations with the presence of psychiatric manifestations in both HSD and EDS reaffirm that the conditions should be treated as a spectrum rather than as wholly separate entities, particularly with respect to psychiatric management. EDS and HSD patients share common psychiatric presentations, though ADHD is more common with HSD.

Abstract
BACKGROUND Joint hypermobility syndrome (JHS) has been found to be associated with anxiety disorders in clinical and nonclinical populations, but to date no studies have evaluated this association in children. The main goal of this study is to evaluate JHS along with anxiety, somatic and behavioral measures in children to clarify if JHS is associated with any of these variables in this age range. METHODS A sample of 160 children (74 girls and 86 boys) ranging from 5 to 17 o were recruited from a Child-Adolescent Mental Health clinic to participate in the study. All children underwent a diagnostic interview using the Mini International Neuropsychiatric Interview for Children and Adolescents. Instruments used include the Child Behavior Checklist (CBCL), the Screening Questionnaire to detect Hypermobility (SQ-CH) and the Children Manifested Anxiety Scale (CMAS-R). RESULTS The prevalence of JHS in this sample was 22%, and this was significantly higher in girls (31%) than in boys (14%) (χ2=6.83; P=.001). The JHS group scored significantly higher in the CMAS-R total anxiety (F=4.51; P=.035), CMAS-R Physiological anxiety (F=7.19; P=.008) and the CBCL somatic complaints (F=8.46; 0.004) and regression analyses showed that these 3 variables were predictors of JHS (χ2=36.77; P<.001; r2=0.22). The JHS group also scored higher in some behavioral measures. CONCLUSION Children with JHS have higher frequency of anxiety disorders and higher intensity of physiological anxiety, somatic complaints, and therefore, JHS might be used as marker for this anxiety phenotype in youngsters.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) and generalized joint hypermobility (JH) are two separated conditions, assessed, and managed by different specialists without overlapping interests. Recently, some researchers highlighted an unexpected association between these two clinical entities. This happens in a scenario of increasing awareness on the protean detrimental effects that congenital anomalies of the connective tissue may have on human health and development. To review pertinent literature to identify possible connections between ADHD and GJH, special emphasis was put on musculoskeletal pain and syndromic presentations of GJH, particularly the hypermobile Ehlers-Danlos syndrome. A comprehensive search of scientific databases and references lists was conducted, encompassing publications based on qualitative and quantitative research. Impaired coordination and proprioception, fatigue, chronic pain, and dysautonomia are identified as potential bridges between ADHD and JH. Based on these findings, a map of the pathophysiological and psychopathological pathways connecting both conditions is proposed. Although ADHD and JH are traditionally separated human attributes, their association may testify for the dyadic nature of mind-body connections during critical periods of post-natal development. Such a mixed picture has potentially important consequences in terms of disability and deserves more clinical and research attention.

Abstract
BACKGROUND Anxiety disorders (AD) are very prevalent in the elderly, tend to compromise quality of life, and generate substantial costs. Considering that the prevention and early detection of anxiety may be relevant to increase health gains in older adults, it would be of great interest to identify whether the joint hypermobility syndrome (JHS) is also related to anxiety disorders in this age range. METHODS Cross-sectional data was collected in a sample of 108 subjects in a rural town in Spain. Instruments included Spielberger STAI, a modified Wolpe Fear Survey Schedule, General health Questionnaire (GHQ)-28, and the anxiety and mood disorders section of the SCID, to assess past year prevalence of anxiety disorders. JHS was evaluated by trained examiners using the "Hospital del Mar criteria". RESULTS Among the 108 subjects (55% women, 45% men) over 60 years old, 21.3% meet criteria for JHS. These subjects scored significantly higher in both State (F = 5.53; p = 0.02) and Trait (F = 4.68; p = 0.03) anxiety and the GHQ 28 (F = 6.29; p = 0.01). Compared with non JHS subjects, they had more AD (34.8% vs. 11.8%; x2 = 6.90; p = 0.02) and mood disorders (30.4% vs. 10.6%; x2 = 5.65; p = 0.041) in the past year prevalence. A multiple logistic regression analysis showed that both JHS (β = 0.196; p = 0.04) and fears (β = 0.34; p = 0.001) are predictors of AD (r2 = 188; p = 0.001) in this population. CONCLUSIONS Joint hypermobility syndrome is associated with anxiety in the elderly population, and it may be used as a physical marker for AD among subjects within this age range.

Abstract
BACKGROUND Joint hypermobility syndrome (JHS)/Ehlers-Danlos syndrome hypermobility type (EDS-HT) is the most common hereditary non-inflammatory disorder of connective tissue, characterized by a wide range of symptoms, mainly joint hyperextensibility and musculoskeletal symptoms. A majority of patients also experiences gastrointestinal (GI) symptoms. Furthermore, JHS/EDS-HT has specifically been shown to be highly prevalent in patients with functional GI disorders, such as functional dyspepsia and irritable bowel syndrome. PURPOSE The aim of this review was to examine the nature of GI symptoms and their underlying pathophysiology in JHS/EDS-HT. In addition, we consider the clinical implications of the diagnosis and treatment of JHS/EDS-HT for practicing clinicians in gastroenterology. Observations summarized in this review may furthermore represent the first step toward the identification of a new pathophysiological basis for a substantial subgroup of patients with functional GI disorders.

Abstract
There is increasing amount of evidence pointing toward a high prevalence of psychiatric conditions among individuals with hypermobile type of Ehlers-Danlos syndrome (JHS/hEDS). A literature review confirms a strong association between anxiety disorders and JHSh/hEDS, and there is also limited but growing evidence that JHSh/hEDS is also associated with depression, eating, and neuro-developmental disorders as well as alcohol and tobacco misuse. The underlying mechanisms behind this association include genetic risks, autonomic nervous system dysfunction, increased exteroceptive and interoceptive mechanisms and decreased proprioception. Recent neuroimaging studies have also shown an increase response in emotion processing brain areas which could explain the high affective reactivity seen in JHS/hEDS. Management of these patients should include psychiatric and psychological approaches, not only to relieve the clinical conditions but also to improve abilities to cope through proper drug treatment, psychotherapy, and psychological rehabilitation adequately coupled with modern physiotherapy. A multidimensional approach to this "neuroconnective phenotype" should be implemented to ensure proper assessment and to guide for more specific treatments. Future lines of research should further explore the full dimension of the psychopathology associated with JHS/hEDS to define the nature of the relationship. © 2017 Wiley Periodicals, Inc.

Abstract
Anxiety and somatic symptoms have a high prevalence in the general population. A mechanistic understanding of how different factors contribute to the development and maintenance of these symptoms, which are highly associated with anxiety disorders, is crucial to optimize treatments. In this article, we review recent literature on this topic and present a redefined model of mind-body interaction in anxiety and somatic symptoms, with an emphasis on both bottom-up and top-down processes. Consideration is given to the role played in this interaction by predisposing physiological and psychological traits (e.g., interoception, anxiety sensitivity, and trait anxiety) and to the levels at which mindfulness approaches may exert a therapeutic benefit. The proposed model of mind-body interaction in anxiety and somatic symptoms is appraised in the context of joint hypermobility syndrome, a constitutional variant associated with autonomic abnormalities and vulnerability to anxiety disorders.

Abstract
BACKGROUND Joint hypermobility syndrome (JHS) has repeatedly been associated with anxiety and anxiety disorders, fibromyalgia, irritable bowel syndrome and temporomandibular joint disorder. However, the neural underpinnings of these associations still remain unclear. This study explored brain responses to facial visual stimuli with emotional cues using fMRI techniques in general population with different ranges of hypermobility. METHODS Fifty-one non-clinical volunteers (33 women) completed state and trait anxiety questionnaire measures, were assessed with a clinical examination for hypermobility (Beighton system) and performed an emotional face processing paradigm during functional neuroimaging. RESULTS Trait anxiety scores did significantly correlate with both state anxiety and hypermobility scores. BOLD signals of the hippocampus did positively correlate with hypermobility scores for the crying faces versus neutral faces contrast in ROI analyses. No results were found for any of the other studied ROIs. Additionally, hypermobility scores were also associated with other key affective processing areas (i.e. the middle and anterior cingulate gyrus, fusiform gyrus, parahippocampal region, orbitofrontal cortex and cerebellum) in the whole brain analysis. CONCLUSIONS Hypermobility scores are associated with trait anxiety and higher brain responses to emotional faces in emotion processing brain areas (including hippocampus) described to be linked to anxiety and somatic symptoms. These findings increase our understanding of emotion processing in people bearing this heritable variant of collagen and the mechanisms through which vulnerability to anxiety and somatic symptoms arises in this population.

Joint hypermobility and the heritable disorders of connective tissue: clinical and empirical evidence of links with psychiatry. Gen Hosp Psychiatry 2015; 37:24-30. [PMID: 25459977 DOI: 10.1016/j.genhosppsych.2014.10.002] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2014] [Revised: 09/14/2014] [Accepted: 10/07/2014] [Indexed: 12/21/2022]
Abstract
OBJECTIVE The heritable disorders of connective tissue (HDCTs) are a group of genetic disorders affecting connective tissue matrix proteins. Fragility, laxity of tissues and joint hypermobility (JH) are commons features of HDCT for which the prognosis may range from benign to life threatening. JH and HDCTs, especially joint hypermobility syndrome, Ehlers-Danlos syndromes and Marfan syndrome, have been associated with psychiatric symptomatology. We explored the existing knowledge concerning this association in order to provide an overview of mental disorders linked to JH/HDCT, as well as the hypotheses proposed to explain such association. METHOD A comprehensive search of scientific online databases and references lists was conducted, encompassing publications based on quantitative and qualitative research, including case reports. RESULTS Psychiatric conditions in which there is some evidence of an association with JH/HDCT are anxiety disorders, depression, schizophrenia, neurodevelopmental disorders (autism, attention deficit/hyperactivity disorder, and developmental coordination disorder), eating disorders, personality disorders and substance use/misuse. CONCLUSION Despite the need of more research, the available data highlight the importance of examining psychiatric symptoms in those affected by JH/HDCT and the importance of providing interventions with a multidisciplinary approach. The relationship between JH/HDCT and mental disorders merits further attention in order to improve current knowledge and clarify a possible common etiology.

Neuroimaging and psychophysiological investigation of the link between anxiety, enhanced affective reactivity and interoception in people with joint hypermobility. Front Psychol 2014; 5:1162.

Abstract
Objective: Anxiety is associated with increased physiological reactivity and also increased “interoceptive” sensitivity to such changes in internal bodily arousal. Joint hypermobility, an expression of a common variation in the connective tissue protein collagen, is increasingly recognized as a risk factor to anxiety and related disorders. This study explored the link between anxiety, interoceptive sensitivity and hypermobility in a sub-clinical population using neuroimaging and psychophysiological evaluation. Methods: Thirty-six healthy volunteers undertook interoceptive sensitivity tests, a clinical examination for hypermobility and completed validated questionnaire measures of state anxiety and body awareness tendency. Nineteen participants also performed an emotional processing paradigm during functional neuroimaging. Results: We confirmed a significant relationship between state anxiety score and joint hypermobility. Interoceptive sensitivity mediated the relationship between state anxiety and hypermobility. Hypermobile, compared to non-hypermobile, participants displayed heightened neural reactivity to sad and angry scenes within brain regions implicated in anxious feeling states, notably insular cortex. Conclusions: Our findings highlight the dependence of anxiety state on bodily context, and increase our understanding of the mechanisms through which vulnerability to anxiety disorders arises in people bearing a common variant of collagen.

Abstract
Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Methods for the genetic analysis of such complex disorders is briefly reviewed, followed by a discussion of the comorbidity of anxiety with other psychiatric disorders and their possible common genetic etiology. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage scans for panic disorder (PD) susceptibility genes have suggested a locus on chromosome arm 7p, and association studies have highlighted many candidate genes. A highly significant association between phobias, panic disorder, and a duplication at chromosomal region 15q24-26 is one of the most exciting findings to date. Emerging molecular genetic technologies and the use of increasingly sophisticated animal models of anxiety provide great promise for the future of the field.

Does the association between mitral valve prolapse and panic disorder really exist? PRIMARY CARE COMPANION TO THE JOURNAL OF CLINICAL PSYCHIATRY 2011; 10:38-47. [PMID: 18311420 DOI: 10.4088/pcc.v10n0107] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2007] [Accepted: 06/13/2007] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Although the possible relationship between panic disorder and mitral valve prolapse (MVP) attracted considerable research interest in the 1980s and 1990s, the reported prevalence of MVP in these patients has been inconsistent and widely variable. Clinical and epidemiologic studies have produced controversial data on possible association or definite causal relationship between these 2 entities. The primary objective of the present review was to summarize the current state of knowledge on the association between panic disorder and MVP, including the influence of diagnostic criteria for MVP on the controversial results. DATA SOURCES We searched MEDLINE, LILACS, and EMBASE databases using the keywords panic and mitral. Inclusion criteria were articles concerning the reciprocal association of MVP and panic disorder, published from the earliest dates available through December 2006. STUDY SELECTION All relevant articles published in English, Spanish, or Portuguese and reporting original data related to the association of MVP and panic disorder were included. Forty articles fulfilling the criteria for inclusion in this review were identified. DATA SYNTHESIS Even though the reported prevalence of MVP in panic disorder varied from 0% to 57%, a significant association between the 2 disorders was documented in 17 of the 40 studies. Such inconsistent results were due to sampling biases in case or control groups, widely different diagnostic criteria for MVP, and lack of reliability of MVP diagnosis. None of the reviewed studies used the current state-of-the-art diagnostic criteria for MVP to evaluate the volunteers. Apparently, the more elaborate the study methodology, the lower the chance to observe a significant relationship between these 2 conditions. CONCLUSIONS Published results are insufficient to definitely establish or to exclude an association between MVP and panic disorder. If any relationship does actually exist, it could be said to be infrequent and mainly occur in subjects with minor variants of MVP. To clarify this intriguing issue, future studies should mainly focus on the observed methodological biases and particularly should use the current criteria for MVP as the standard for evaluation.

Abstract
OBJECTIVE To explore the frequency of Joint Hypermobility Syndrome (JHS) among university students and assess whether a relationship exists between this collagen condition and certain psychological variables. METHOD A cross-sectional sample of 365 undergraduates at a French university was assessed with the Brighton's criteria for JHS, Somatosensory Amplification Scale (SSAS), Liebowitz Social Anxiety Scale (LSAS), and Hospital Anxiety and Depression Scale (HADS). RESULTS 39.5% of the participants met Brighton's criteria for JHS. Scores of somatosensory amplification were higher among participants with JHS (t = -2.98; p = 0.03) independent of gender. Female participants with JHS had higher scores in depression (t = -2.01; p = 0.04) and general anxiety (t = -2.35; p = 0.01) than women without JHS. The percentage of males with a medium/high level of social anxiety was greater among participants with JHS (78.6% vs. 41.7%; chi2 = 6.18;p = 0.01). Logistic regression demonstrated that male sex and low level of somatosensory amplification are variables contrary to the presence of JHS. CONCLUSION JHS is a frequent condition among young people evaluated. JHS is associated with psychological distress and higher levels of somatosensory amplification.

Abstract
OBJECTIVE The objective of the study was to assess whether joint hypermobility syndrome (JHS) is a risk factor for developing anxiety disorders using a 15-year prospective cohort study. METHOD The initial cohort recruited 158 subjects aged 16 to 20 years from the general population in a Spanish rural town. The cohort was studied at baseline and at a 15-year follow-up. Joint hypermobility syndrome was assessed using Beighton's criteria, and the psychiatric disorders were assessed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Disorders. Subjects with anxiety disorders at baseline were excluded from the follow-up. RESULTS Joint hypermobility syndrome at baseline was found in 29 of 158 subjects (21.1%). Cumulative incidence of panic/agoraphobia disorder at follow-up, as main diagnosis, was significantly higher for the JHS group (41.4%) than for the control group (1.9%), with a relative risk of 22.3 [95% confidence interval (CI) 4.6-108.7, P<.0001] (Number Needed to Treat [NNT] 3, 95% CI 2.9-2.3). Incidence of social phobia and simple phobia was also significantly higher for the JHS group [relative risk (RR)=6.52, 95% CI 1.7-24.2, P<.001 and RR=3.31, 95% CI 1.1-9.6, P=.02, respectively]. Moreover, anxiolytic drug use was nearly fourfold higher among JHS compared to non-JHS subjects. CONCLUSION Joint hypermobility syndrome was associated with higher risk of developing anxiety disorders. If replicated, these findings may give enhanced value to JHS assessment in clinical and general population studies.

Abstract
BACKGROUND Panic attacks are heterogeneous with regards to symptom profile. Subtypes of panic attacks have been proposed, of which the most investigated is respiratory panic attacks (RPA). Limited information exists about RPA in the general population. METHOD The prevalence and correlates of RPA and non-respiratory panic attacks (NRPA) were examined in a subsample (n=8.796) of individuals participating in a cross-sectional survey of the adult general population of six European countries. Panic attacks, mental disorders, and chronic physical conditions were assessed with the Composite International Diagnostic Interview (CIDI) 3.0. Data on use of health services and disability were obtained. RESULTS The lifetime prevalence of RPA was 6.77 and the 12-month prevalence was 2.26. No robust associations of RPA with sociodemographic characteristics, mental disorders or physical conditions were found as compared to NRPA. RPA were associated with increased use of health services but similar disability in comparison to NRPA. LIMITATIONS Few direct data are available on the validity of the CIDI to assess RPA. Other definitions of RPA exist in the literature. CONCLUSIONS Our findings suggest that there are very few differences between RPA and NRPA and do not support the need of subtyping panic attacks in current classification systems.

Abstract
Joint hypermobility (JH) is considered a common benign, hereditary, overlap, connective tissue disorder with a prevalence in the general population of about 10% in European populations and 25% in other ethnic groups. JH shows an association with mitral valve prolapse and fibromyalgia. However, the most significant and important association between joint hypermobility syndrome (JHS) and any other disorder from a clinical point of view is with panic disorder. This article summarizes all published studies on JHS and anxiety, analyzing the main results and limitations. An overview of the etiologic explanation of the association between JH and anxiety, with special focus on genetic findings, is also included. The most relevant conclusions are the following: JHS is more prevalent in individuals with panic disorder/agoraphobia, and patients with JHS present with greater prevalence of panic disorder/agoraphobia. In addition, there is an association between JHS severity and severity of anxiety, and mitral valve prolapse plays a secondary role in the association between JHS and anxiety. New fields of research based on these data are suggested.

Abstract
30 subjects with BJHS (Hypermobile) ( M age = 32.3 yr., SD = 10.4) and two control groups, 25 healthy subjects (Healthy) ( M age = 33.9 yr., SD = 93) and 30 fibromyalgic patients (Fibromyalgic) ( M age = 32.2 yr., SD = 9.4), were given the Symptom Checklist-90-R, the Illness Behavior Questionnaire, the Female Functional Symptoms Frequency (FFF) and the Male Functional Symptoms Frequency (MFF), derived from the DSM-III–R, evaluating functional somatic disturbances and their intensity, and the Symptom Questionnaire. The mean scores for the Hypermobile group showed significant psychological distress and increased frequency and intensity of somatic symptoms. Scores on Anxiety and Somatic Symptoms, General Hypochondriasis, Disease Conviction, Affective Disturbance, Denial, and Irritability were significantly higher in the Hypermobile than in the Healthy group. Elevated scores were found for the Fibromyalgic group on the Illness Behavior Questionnaire subscales for Psychological vs Somatic Focus, Disease Affirmation, and Discriminating Factors when compared with the Hypermobile group. Considerable emotional symptoms were detected which should not be underestimated by physicians when establishing an integrated biopsychosocial therapy.

Abstract
OBJECTIVE To demonstrate the high frequency and lack of diagnosis of joint hypermobility syndrome (JHS) and the seriousness of vascular Ehlers-Danlos syndrome (VEDS). METHODS Two hundred forty-nine Chilean patients with hereditary disorders of the connective tissues (CTDs) and 64 control subjects were evaluated for the diagnoses of JHS and VEDS using the validated Brighton criteria, as compared with the traditional Beighton score. In addition, the presence of blue sclera was determined, with the degree of intensity graded as mild, moderate, or marked. RESULTS The frequency of hereditary CTDs was 35%, with diagnoses of JHS in 92.4% of subjects, VEDS in 7.2%, and osteogenesis imperfecta in 0.4%. The Beighton score proved to be insufficient for the diagnosis of JHS (35% of subjects had a negative score), whereas the Brighton criteria yielded positive findings (a diagnosis of JHS) in 39% of control subjects. Blue sclera was frequent, being identified in 97% of JHS patients and 94% of VEDS patients. Moderate osteopenia/osteoporosis was observed in 50% of patients with VEDS and 26% of those with JHS. Dysautonomia, dyslipidemia, and scoliosis were more frequent in VEDS patients than in JHS patients. The typical JHS facial appearance and the "hand holding the head sign" were identified. Raynaud's phenomenon was extremely rare in JHS patients (2%). Ruptured uterus and cerebral aneurysm occurred in 12% and 6% of VEDS patients, respectively. Spontaneous pneumothorax was more frequent in VEDS patients (11%) than in JHS patients (0.9%). CONCLUSION JHS is very frequent but usually undiagnosed. The Beighton score is an insufficient method for JHS diagnosis. We recommend that physicians learn to recognize the typical facial features of JHS and be able to identify blue sclera. We also propose that validated hypermobility criteria be routinely used. Further research is needed to determine why the prevalence of JHS is so high in Chile.

Abstract
Encouraged by the positive relationship between joint laxity and panic anxiety, our objective in this study was to compare widespread cultural fears in subjects with and without joint hypermobility syndrome and to assess whether this relationship is sustained for common fears as well. A sample consisting of 1,305 subjects from a rural town were assessed for joint hypermobility syndrome using Beighton's criteria. We assessed fear intensity and frequency using a modified version of the Fear Survey Schedule (FSS-III). Intense fears, defined with a score of 3-4, were compared between hypermobile and nonhypermobile subjects. The analysis was carried out separately for men and women. Nonparametric analysis was applied throughout. Joint hypermobility syndrome was found in 19.9% (141) of women and 6.9% (41) of men. Concerning the fear survey, when we compared the groups with and without joint hypermobility, the mean total scores for both genders were significantly higher for the hypermobile group. When we analyzed each item individually, 43 out of the 44 most severe fears in women and 36 out of the 39 in men, scores were significantly higher in the hypermobile group. We found significant differences between subjects with and without joint hypermobility when assessing specific fears, reinforcing the hypothesis that intensity of fears is greater in subjects with joint hypermobility syndrome. These results show that the association of joint laxity and phobic anxiety is sustained for intense fears and might represent a susceptibility factor for these anxiety conditions.

Abstract
The relationship between weather conditions and psychiatric disorders has been a continuous subject of speculation due to contradictory findings. This study attempts to further clarify this relationship by focussing on specific conditions such as panic attacks and non-panic anxiety in relation to specific meteorological variables. All psychiatric emergencies attended at a general hospital in Barcelona (Spain) during 2002 with anxiety as main complaint were classified as panic or non-panic anxiety according to strict independent and retrospective criteria. Both groups were assessed and compared with meteorological data (wind speed and direction, daily rainfall, temperature, humidity and solar radiation). Seasons and weekend days were also included as independent variables. Non-parametric statistics were used throughout since most variables do not follow a normal distribution. Logistic regression models were applied to predict days with and without the clinical condition. Episodes of panic were three times more common with the poniente wind (hot wind), twice less often with rainfall, and one and a half times more common in autumn than in other seasons. These three trends (hot wind, rainfall and autumn) were accumulative for panic episodes in a logistic regression formula. Significant reduction of episodes on weekends was found only for non-panic episodes. Panic attacks, unlike other anxiety episodes, in a psychiatric emergency department in Barcelona seem to show significant meteorotropism. Assessing specific disorders instead of overall emergencies or other variables of a more general quality could shed new light on the relationship between weather conditions and behaviour.

Abstract
OBJECTIVE The purpose of this study is to test the association between joint hypermobility syndrome (JHS) and panic disorder (PD) and to determine whether mitral valve prolapse (MVP) modifies or accounts in part for the association. METHOD A total of 115 subjects are included in this study in three groups. Group I (n = 42): panic disorder patients with MVP. Group II (n = 35): panic disorder patients without mitral valve prolapse. Group III (n = 38): control subjects who had mitral valve prolapse without any psychiatric illness. Beighton criteria were used to assess joint hypermobility syndrome. Two-dimensional and M-mode echocardiography was performed on each subject to detect mitral valve prolapse. RESULTS Joint hypermobility syndrome was found in 59.5% of panic disorder patients with mitral valve prolapse, in 42.9% of patients without mitral valve prolapse and in 52.6% of control subjects. Beighton scores was 4.93 +/- 2.97 in group I, 4.09 +/- 2.33 in group II, and 4.08 +/- 2.34 in group III. There was no significant difference between groups according to Beighton scores. CONCLUSION We did not detect a statistically significant relationship between panic disorder and joint hypermobility syndrome. Mitral valve prolapse and joint hypermobility syndrome are known to be etiologically related and we suggest that mitral valve prolapse affects the prevalence of joint hypermobility syndrome in the panic disorder patients.

Abstract
This study examines the association between joint hypermobility syndrome and anxiety in a nonclinical sample. Subjects (N = 526) receiving a medical check-up were assessed with the Hospital del Mar hypermobility criteria and the State-Trait Anxiety Inventory. Scores for trait anxiety, and to a lesser extent state anxiety, were significantly higher among subjects with joint hypermobility syndrome than among subjects without this syndrome (median trait anxiety scores for women: 17 versus 11; median scores for men: 13 versus 1). These findings indicate that the association of joint hypermobility syndrome and anxiety holds even for subjects with no psychiatric diagnosis. Therefore, it seems that this benign connective tissue disorder is a predisposing factor for trait anxiety. However, it is necessary to further explore and define the biological basis of this syndrome, as well as its associations and clinical expressions, which interact with great complexity.

Abstract
Anxiety disorders are complex and common psychiatric illnesses associated with considerable morbidity and social cost. We have studied the molecular basis of the cooccurrence of panic and phobic disorders with joint laxity. We have identified an interstitial duplication of human chromosome 15q24-26 (named DUP25), which is significantly associated with panic/agoraphobia/social phobia/joint laxity in families, and with panic disorder in nonfamilial cases. Mosaicism, different forms of DUP25 within the same family, and absence of segregation of 15q24-26 markers with DUP25 and the psychiatric phenotypes suggest a non-Mendelian mechanism of disease-causing mutation. We propose that DUP25, which is present in 7% control subjects, is a susceptibility factor for a clinical phenotype that includes panic and phobic disorders and joint laxity.

This study attempted to replicate previous reports of associations between panic disorder and joint hyperlaxity. The authors also examined possible associations between reacitivity to carbon dioxide (CO(2)), a model for panic vulnerability, and hyperlaxity in healthy volunteers. One hundred and one patients with DSM-IV panic disorder and 39 healthy volunteers were assessed for hyperlaxity by Beighton's criteria. Healthy volunteers also received two vital capacity inhalations of CO(2). Thirteen (13%) patients had five or more hyperlax joints. This rate did not differ from that in the healthy volunteers. Anxiety in healthy volunteers, as measured by the NIMH self-rating scale, DSM-IV panic symptom scores, and 100 mm visual analog scales of anxiety, increased after CO(2) from a mean of 1.8 to 2.8 (not significant); from 0.5 to 4 ( p < 0.001) and from 8.7 to 11.6 mm ( p < 0.1), respectively. There were no associations between responses to CO(2) and hyperlaxity. Copyright 2001 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE To test the hypothesis that joint hyperlaxity can play some role in the pathogenesis of pain in primary fibromyalgia. METHODS A total of 66 women with fibromyalgia (according to the 1990 American College of Rheumatology criteria) and 70 women with other rheumatic diseases were examined for joint laxity based on 5 criteria (The Non-Dominant Spanish modification). Individuals meeting 4 or 5 criteria were considered to be hyperlax. RESULTS Joint hyperlaxity was detected in 18 (27.3%) of the patients with fibromyalgia and 8 (11.4%) of those with another rheumatic disorder. The statistical analysis revealed significant differences (P < 0.05) between both groups. CONCLUSION The results of this study suggest that joint hypermobility and fibromyalgia are associated. Joint hyperlaxity may play a prominent role in the pathogenesis of pain in fibromyalgia.

Abstract
A case-control study was designed to test the association between joint hypermobility syndrome (JHS), an inherited disorder of collagen synthesis, and anxiety and phobic disorders. One hundred fourteen cases of JHS diagnosed at the rheumatology outpatient clinic of the Hospital del Mar (Barcelona) were compared to 59 control subjects randomly selected from patients seen at the same clinic. Both cases and controls were examined by a psychologist who used the Structured Clinical Interview for DSM-III-R and who was unaware of their medical diagnoses. DSM-III-R diagnoses of panic disorder, agoraphobia, and simple phobia, but not generalized anxiety disorder, dysthymic disorder, or major depression were found to be highly associated with JHS (age- and sex-adjusted odds ratio = 10.7). Mitral valve prolapse (MVP) was present only among JHS cases. Among cases of JHS, subjects with MVP were almost three times more likely to suffer from anxiety than subjects without MVP (odds ratio = 2.95), although the association was not statistically significant. The strong association between panic anxiety and JHS appears to occur at a higher level than the association between panic and MVP, and provides a new basis for further studies on the genetic background of panic-anxiety.
