As low-grade gliomas (LGG) are slow-growing brain tumours, the course of the disease is hard to predict. The aim of this study was to investigate the relatives' experiences of living close to a person with LGG (grade 2). It is based on semi-structured interviews with 15 family members (60% women, mean age 47 years). The interviews were conducted by telephone three and seven years after diagnosis.The thematic analysis resulted in one overarching and recurring theme, namely the difficulties of communicating openly about what the disease entails, as well as four related themes. LGG is perceived as a scary and mysterious disease requiring new priorities to be set up in families to fulfil the needs of the person with LGG. A tangible impact is an altered relationship due to a stealthy change in the person with LGG. Living with a person with LGG for many years can be likened to travelling a long and lonely road.The relatives expressed the concern that they receive insufficient support from the healthcare system. The key clinical implication is to meet the relatives' own right to support, as well as providing information about the changeability of the disease and possible personality changes.

This study is part of a longitudinal research program, in which patients diagnosed with low-grade gliomas (LGG: n = 13), as well as healthy controls (n = 13), were consecutively recruited and neuropsychologically followed for 7 years. The patients are followed up regardless of variations in treatment. A composite score is used (Global Deficit Score: GDS) included cognitive measures where at least five patients had a negative change: information processing speed, speed of naming, construction ability, verbal fluency, non-verbal thinking, and immediate non-verbal memory. The most important finding in this 7-year follow-up study is that two-thirds of the patients developed cognitive impairment. The remaining third of the patients showed stability in their cognitive ability and were still alive 17 years after diagnosis. Younger patients with tumors in the right frontal or posterior regions showed a more favorable development. Patients with frontal tumors and a declined GDS show also significant changes in executive functions. Given the limited number, no firm conclusions can be drawn regarding the impact of tumor localization. The impact of LGG on cognition and the survival time after diagnosis varies considerably between patients. However, most of the patients (69%) showed cognitive impairment during the seven years we followed them.

Introduction: Intriguingly, autism spectrum disorders (ASD) and symptomatic generalised joint hypermobility (S-GJH) (e.g. hypermobility spectrum disorders and Ehlers Danlos Syndrome) share several clinical manifestations including motor difficulties, sensory hypersensitivity and autonomic dysfunction. Moreover, many syndromic forms of ASD manifest a hypermobile phenotype. Despite the increased interest in the area, few systematic studies are available.

Objectives: This large cross-sectional comparative study aimed to examine the association between S-GJH and ASD in adults.

Methods: We assessed GJH by physical examination using the Beighton Scoring System (BSS) and collected data on musculoskeletal symptoms and skin abnormalities amongst 156 adult patients with ASD and 413 adult community controls. A proxy for S-GJH was created by combining a positive BSS with at least one additional musculoskeletal symptom or skin abnormality.

Results: The prevalence of S-GJH was significantly higher amongst patients with ASD than amongst controls (16.7% vs 4.8%, p< .001). A logistic regression model, adjusting for candidate covariates of GJH (age, sex, race), revealed a significant influence of ASD on S-GJH with adjusted odds ratio of 5.4 (95% CI 2.8-10.5, p< .001).

Conclusions: ASD and S-GJH are associated in adults. If recognised, musculoskeletal complications related to S-GJH can be relieved by physiotherapy. Clinicians should be familiar with that symptoms frequently occurring in GJH such as pain, fatigue and orthostatic intolerance may mimic or aggravate psychiatric symptoms (e.g. depression, anxiety). Knowledge about comorbidities may provide clues to underlying aethiopathological factors. Future research to clarify the mechanisms behind this association and to evaluate how comorbid S-GJH affects ASD outcome is warranted.

Autism spectrum disorder (ASD) and generalised joint hypermobility (GJH) share a number of clinical manifestations including proprioceptive impairment, motor difficulties, sensory hypersensitivity, and autonomic dysfunction. Clinical observations suggest that GJH is overrepresented in ASD. However, there are currently few systematic studies available. Knowledge about comorbidities may unfold common aetiopathological pathways underlying the association and improve the clinical management. The aim of this large, cross-sectional comparative study is to evaluate the relationship between ASD and GJH in adults. Data on joint hypermobility, symptoms associated with both hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS), lifetime psychiatric diagnoses, psychiatric rating scales for ASD and attention deficit hyperactivity disorder (ADHD), and socio-demographics was collected for 199 individuals with ASD and 419 non-ASD community controls. Logistic regression models adjusting for covariates (age, sex, ethnicity) revealed a significant relationship between ASD and GJH and between ASD and symptomatic GJH, with adjusted odds ratios of 3.1 (95% CI: 1.9, 5.2; p < 0.001) and 4.9 (95% CI: 2.6, 9.0; p < 0.001), respectively. However, the high prevalence of comorbid ADHD in the study sample reduces the generalizability of the results among individuals with ASD without comorbid ADHD. Possibly, an additional ADHD phenotype is the primary driver of the association between ASD and GJH. Furthermore, GJH with additional self-reported symptoms, suggestive of HSD/hEDS, showed a stronger association with ASD than did non-specified GJH, indicating that symptomatic GJH plays a greater role in the relationship than non-specified GJH does. Therefore, the current study underscores the need of careful sample subclassifications. ASD with GJH may represent a novel subgroup of ASD in terms of aetiopathology and clinical presentation. Future research should elucidate the aetiological factors behind the association between ASD and GJH and evaluate how the comorbidity of GJH affects ASD outcomes.

Introduction: There is growing evidence that generalised joint hypermobility (GJH) is associated with several psychiatric conditions. There are no previous studies on adult ADHD.

Objectives: To evaluate, in a large Swedish sample, if generalised joint hypermobility and adult ADHD are associated.

Methods: 431 adults with ADHD and 417 controls were included. GJH was assessed by the Beighton Score, a physical examination, and the 5PQ, a self-report screening tool. Exploratively, reported musculoskeletal symptoms and abnormal skin manifestations suggestive of symptomatic GJH (e.g. Ehlers-Danlos syndrome), were assessed to differentiate this group from the general GJH group. Logistic regressions determined the influence of an ADHD diagnosis and known covariates (age, sex and ethnicity) on GJH and symptomatic GJH respectively.

Results: ADHD was associated to GJH, as defined by the Beighton Score and the 5PQ, with adjusted odds ratios of 4.65 (CI 95% 3.01-7.18, p<.005) and 1.86 (CI 95% 1.39-2.48, p<.005), respectively. Likewise, ADHD and symptomatic GJH were associated withadjusted odds ratios of 6.94 (CI 95% 4.05-11.89, p<.005) and 2.66 (CI 95% 1.94-3.66, p<.005).

Conclusions: GJH and adult ADHD are associated conditions. Symptomatic GJH, defined as additional symptoms of pain and/or skin manifestations, has a considerably stronger link to adult ADHD than unspecific GJH has. GJH may represent a marker of an underlying systemic disorder with physical manifestations in connective tissue as well as behavioural manifestations including hyperactivity, impulsiveness and inattentiveness. Future studies should investigate if this represents a novel subtype of ADHD and if symptomatic GJH affects the ADHD management.

Growing evidence suggests an unexpected association between generalised joint hypermobility (GJH) and several psychiatric conditions, and a shared pathophysiology has been proposed. No previous studies on adult attention-deficit/hyperactivity disorder (ADHD) are available. This study aimed to evaluate the association between adult ADHD and GJH. A total of 431 adults with ADHD and 417 non-ADHD controls were included in this cross-sectional comparative study. GJH was assessed by physical examination following the Beighton scoring system (BSS). Furthermore, musculoskeletal symptoms and skin abnormalities were queried to create a proxy for symptomatic GJH (e.g., Hypermobility spectrum disorders and Ehlers-Danlos syndrome) to differentiate this from non-specified GJH defined by BSS only. Logistic regression examined the influence of ADHD and candidate covariates (age, sex, ethnicity) on GJH and symptomatic GJH, respectively. ADHD was significantly associated with GJH, as defined by the BSS, with adjusted odds ratios of 4.7 (95% confidence interval [CI] 3.0-7.2, p < .005). Likewise, ADHD was significantly associated with symptomatic GJH, as defined by the BSS and additional symptoms, with adjusted odds ratios of 6.9 (CI 95% 4.1-11.9, p < .005). Our results suggest that GJH may represent a marker for an underlying systemic disorder involving both connective tissue and the central nervous system. GJH with additional musculoskeletal symptoms and/or skin abnormalities has a considerable stronger link to adult ADHD than non-specified GJH has, and may need awareness in ADHD management. Future studies should investigate the mechanisms behind this association and how comorbid GJH affects ADHD outcome.

Background: Despite major research efforts, current recommendations of treatment interventions for adolescents with anorexia nervosa are scarce, and the importance of patient satisfaction for treatment outcome is yet to be established. The overall aim of the present study was to examine treatment interventions and patient satisfaction in a naturalistic sample of adolescents with anorexia nervosa or subthreshold anorexia nervosa and possible associations to outcome defined as being in remission or not at treatment follow-up.

Methods: Participants were identified through the Swedish national quality register for eating disorder treatment (SwEat). The samples consisted of 1899 patients who were follow-up registered 1 year after entering treatment and 474 patients who had completed a 1-year patient satisfaction questionnaire. A two-step cluster analysis was used for identifying subgroups of patients who received certain combinations and various amounts of treatment forms.

Results: Patients who received mainly family-based treatment and/or inpatient care were most likely to achieve remission at 1-year follow-up, compared to patients in the other clusters. They were also younger, in general. Individual therapy was the most common treatment form, and was most appreciated among the adolescents. At 1-year follow-up, many patients reported improvements in eating habits, but far fewer reported improvements regarding cognitive symptoms. Overall, the patients rated the therapist relationship in a rather positive way, but they gave quite low ratings to statements associated with their own participation in treatment.

Conclusions: The results indicate that young adolescents who receive mainly family-based treatment and/or inpatient care respond more rapidly to treatment compared to older adolescents who receive mainly individual therapy or mixed treatment interventions. At 1-year follow-up, the adolescents reported improvements in behavioral symptoms and seemed quite satisfied with the therapist relationship.

Introduction: Recently, schizotypal personality traits were measured in a multinational sample recruited from 14 countries, however no Scandinavian cohort was included. The aim of this study was, therefore, to measure schizotypal personality traits in Swedish-speaking populations, with and without psychiatric disorders, and to investigate the psychometric properties of the Swedish version of the Schizotypal Personality Questionnaire-Brief (SPQ-B).

Methods: The SPQ-B results from 50 psychiatric patients were compared to controls (n = 202). An additional sample of 25 controls completed the full SPQ twice and we calculated test-retest reliability for SPQ and SPQ-B. We estimated the internal consistency for SPQ-B and SPQ-B factors with omega. We compared the results of SPQ-B (M and SD) in patient and control groups to corresponding results worldwide.

Results: We found similarity between our SPQ-B scores and those from other published samples. SPQ-B showed good internal consistency and acceptable test-retest correlations. The results indicate that the Swedish version of the instrument is valid and can differentiate psychiatric cohorts from non-psychiatric controls.

Conclusion: The Swedish version of the SPQ-B exhibit good psychometric properties and is useful for assessing schizotypal traits in clinical and non-clinical populations.

BACKGROUND: The conventional way to identify generalised joint hypermobility is by a physical examination according to the Beighton Score. However, a physical examination is time-consuming in clinical practise and may be unfeasible in population-based studies. The self-assessment five-part questionnaire on hypermobility (5PQ) offers a more practicable way to identify GJH. The aim of this study was to test validity and reliability of the five-part questionnaire on hypermobility (5PQ) translated into Swedish on a non-clinical adult population.

METHODS: A structured procedure was used for the translation of the 5PQ into Swedish. The Beighton Score was used as reference standard for generalised joint hypermobility. Test-retest reliability was tested in a separate group who filled in the questionnaire twice with a ten-week interval. Participants consisted of a convenience sample recruited in Stockholm, Sweden (2017).

RESULTS: A total of 328 participants were included in the study, 297 participants in the validity group and 31 participants in the reliability group. When evaluated against a present Beighton Score with an age-dependent cut-off, the Swedish 5PQ attained a sensitivity of 91%, a specificity of 75% and an area under the curve of 0.87. The Swedish 5PQ showed substantial to almost perfect test-retest reliability.

CONCLUSIONS: The Swedish 5PQ is a valid and reliable instrument to screen for or to identify generalised joint hypermobility.

Background: It is well known that a wide range of psychiatric disorders co-occur with attention deficit hyperactivity disorder. In this study we aimed to examine the associations of psychiatric comorbidity in ADHD with symptom severity and level of functioning.

Methods: We used data from the Swedish National Quality Registry for ADHD Treatment Follow-up and identified comorbid diagnoses in a sample of 3246 Swedish children and adolescents with ADHD. We investigated the association of comorbidity with symptom severity and level of function by multiple linear regressions.

Results: Autism spectrum disorder, anxiety and affective disorders, oppositional defiant disorder or conduct disorder, learning disorders, and multiple comorbid disorders associate to lower levels of functioning compared to ADHD only. Multiple comorbidity, autism spectrum disorder, oppositional defiant or conduct disorders and tic disorders relate to ADHD symptom severity.

Conclusions: Comorbidity subgroups with ADHD differ in functional impairment and ADHD symptoms severity. Information on comorbidity profiles could be used for treatment planning more adapted to the individual. Especially those who have autism spectrum disorders and multiple comorbid disorders are at risk of severe ADHD symptoms and low level of functioning.
