The Contribution of Psychological Symptoms to Cognitive Difficulties in Youth With Postural Orthostatic Tachycardia Syndrome and Chronic Pain.

INTRODUCTION: Subjectively experienced cognitive difficulties are common in youth with postural orthostatic tachycardia syndrome. The pathophysiological and psychological contributions of these cognitive impairments remain unclear. METHOD: Participants were 96 adolescents and young adults diagnosed with postural orthostatic tachycardia syndrome and admitted to an intensive pain treatment program. Participants completed cognitive assessment and measures of postural orthostatic tachycardia syndrome symptoms, pain intensity, pain catastrophizing, anxiety, depression, and functional disability. RESULTS: Self-reported autonomic symptom intensity, but not severity of heart rate change, was associated with cognitive performance. Symptoms of depression were associated with decreases in most measures of cognitive functioning. Pain intensity, pain catastrophizing, and depression but not cognitive scores and physiological measures, were significant predictors of disability. CONCLUSION: Depression appears to be a significant contributor to the cognitive difficulties in youth with postural orthostatic tachycardia syndrome. These findings highlight the importance of assessing and treating affective symptoms in this population along with medical and lifestyle approaches to treating postural orthostatic tachycardia syndrome symptoms.

Stories in the Mind? The Role of Story-Based Categorizations in Motion Classification.

Categorization is fundamental for spatial and motion representation in both the domain of artificial intelligence and human cognition. In this paper, we investigated whether motion categorizations designed in artificial intelligence can inform human cognition. More concretely, we investigated if such categorizations (also known as qualitative representations) can inform the psychological understanding of human perception and memory of motion scenes. To this end, we took two motion categorizations in artificial intelligence, Motion-RCC and Motion-OPRA1 , and conducted four experiments on human perception and memory. Participants viewed simple motion scenes and judged the similarity of transformed scenes with this reference scene. Those transformed scenes differed in none, one, or both Motion-RCC and Motion-OPRA1 categories. Importantly, we applied an equal absolute metric change to those transformed scenes, so that differences in the similarity judgments should be due only to differing categories. In Experiments 1a and 1b, where the reference stimulus and transformed stimuli were visible at the same time (perception), both Motion-OPRA1 and Motion-RCC influenced the similarity judgments, with a stronger influence of Motion-OPRA1 . In Experiments 2a and 2b, where participants first memorized the reference stimulus and viewed the transformed stimuli after a short blank (memory), only Motion-OPRA1 had marked influences on the similarity judgments. Our findings demonstrate a link between human cognition and these motion categorizations developed in artificial intelligence. We argue for a continued and close multidisciplinary approach to investigating the representation of motion scenes.

Longitudinal assessment of behaviour in young children undergoing general anaesthesia.

BACKGROUND: Exposure to general anaesthesia in children might increase the risk of long-term behavioural problems. It is unclear if any behavioural changes in the short term after anaesthesia could be associated with long-term problems. The goal of the current study was to evaluate the short-term trajectory of parent-reported behaviour measured by the Behaviour Assessment System for Children, third edition (BASC-3) amongst children aged 2.5-6 yr who underwent general anaesthesia for elective surgery. METHODS: Children who were undergoing general anaesthesia for surgery were recruited for assessment of behaviour on two occasions: preoperatively (from 1 week to 1 day before anaesthesia), and 3 months postoperatively. To assess longitudinal changes in the parent-reported behaviour measured by BASC-3, linear mixed models were built with visit number included as a categorical variable and subject-specific random intercepts. RESULTS: Sixty-eight children (37 girls [54%]) were enrolled in the study and completed both assessments. At 3 months after anaesthesia, statistically significant improvements (decrease in T scores) in internalising problems (-2.7 [95% confidence interval -4.2 to -1.1]), anxiety (-2.5 [-4.4 to -0.5]), and somatisation (-3.0 [-5.2 to -0.9]) were found. There were no significant differences in scores between visits for other composites or scales. The pattern of results did not depend upon prior anaesthesia exposure. CONCLUSIONS: Anaesthesia for elective surgery in young children was associated with a small decrease in internalising problems but no changes in other areas of behavioural problems when assessed at 3 months postoperatively, including in children with prior exposure to anaesthesia.

Longitudinal assessment of cognitive function in young children undergoing general anaesthesia.

BACKGROUND: Exposure to general anaesthesia in children may be related to deficits in certain areas of cognition. It is unclear if these deficits could be measured in the immediate postoperative period in young children. The goal of the current study was to evaluate the trajectory of cognitive function in the domains of processing speed, working memory, and fine motor skills amongst children aged 2.5-6 yr who underwent general anaesthesia for elective surgery. METHODS: Children who were scheduled to receive general anaesthesia for surgery were recruited for assessment of cognitive function at three times: preoperatively, 1-2 weeks postoperatively, and 3 months postoperatively. Assessments included processing speed, working memory, and fine motor skills. To assess longitudinal changes in the cognitive outcomes, linear mixed models were built with visit number included as a categorical variable and subject-specific random intercepts. RESULTS: Sixty-one children (33 girls [54%]) enrolled in the study. Twenty-three children (38%) had received general anaesthesia previously. Significant improvements in picture memory, cancellation, and the processing speed composite were found at Visit 2. The improvement in cancellation and processing speed composite remained significant at Visit 3. Statistically significant improvement in Mullen fine motor score was noticed at Visit 3 compared with Visit 1. The pattern of results did not depend upon prior anaesthesia exposure. CONCLUSIONS: General anaesthesia for elective surgery in young children was not associated with declines in working memory, processing speed, and fine motor skills in the first 3 months postoperatively, including in children with prior exposure to anaesthesia.

Neuropsychological Functioning in Alexander Disease: A Case Series.

Limited information is known about neuropsychological outcomes in Alexander disease, a rare leukodystrophy. Two pediatric cases are summarized. Case 1 (evaluations at 6, 7, 9, and 12 years of age) represents Type I Alexander disease with associated seizures. Case 2 (evaluations at 12, 13, and 16 years of age) represents Type II Alexander disease without additional complications. Case 1 experienced declines in intellectual functioning, visual motor skills, receptive vocabulary, verbal memory, and academic achievement. Case 2 experienced variable neurocognitive change and academic functioning, with average word reading and spelling. Verbal memory also remained intact. Taken together, individuals with Alexander disease may experience cognitive decline to variable degrees. Type I Alexander disease, associated with earlier onset and additional neurological complications, may presage greater cognitive decline than Type II. Due to variability in functioning over time, it is critical to follow individuals across development to make recommendations for educational and treatment planning.

Assessment and Treatment of Noise Hypersensitivity in a Teenager with Autism Spectrum Disorder: A Case Study.

Noise hypersensitivity is a poorly understood symptom of Autism Spectrum Disorder (ASD). For some, problem behaviors co-occur with the aversive noise. Limited literature exists on treating noise hypersensitivity; however, noise hypersensitivity may be related to a specific phobia. This case study utilizes modified Cognitive Behavioral Therapy (CBT) to address anxiety, avoidance, and problem behaviors evoked by noise in a teen with ASD and mild Intellectual Disability (ID). Using multi-method assessment and individualized treatment, problem behaviors reduced, and independent coping strategies use occurred. Successful desensitization supports the efficacy of modified CBT as a treatment for noise-related anxiety and problem behaviors in individuals with ASD and ID. Outcomes are discussed considering intervention difficulties for noise hypersensitivity in a complex and diverse population.

These recommendations are based on the experiences of researchers who have spent time analyzing and working with both database systems and have developed a methodology for each. Manufacturers can leverage the suggested practices described in this article to address regulatory requirements.

Association of Comorbid Mood and Anxiety Disorders With Autism Spectrum Disorder.

Importance: It is critical to evaluate the risk of comorbid psychiatric diagnoses to meet the needs of individuals with autism spectrum disorder (ASD). Objective: To examine whether individuals with ASD are at greater risk for comorbid diagnoses of depression, anxiety, or bipolar disorder. Design, Setting, and Participants: This cohort study used data from a population-based birth cohort of 31 220 individuals born in Olmsted County, Minnesota, from January 1, 1976, to December 31, 2000. Patients with research-identified ASD were previously identified using a multistep process that evaluated signs and symptoms abstracted from medical and educational records. For each of the 1014 patients with ASD, 2 age- and sex-matched referents who did not meet criteria for ASD were randomly selected from the birth cohort (n = 2028). Diagnosis codes for anxiety, depression, and bipolar disorders were electronically obtained using the Rochester Epidemiological Project records-linkage system. Data analysis was performed from July 1, 2018, to April 1, 2019. Main Outcomes and Measures: Cumulative incidence of clinically diagnosed depression, anxiety, and bipolar disorder through early adulthood in individuals with ASD compared with referents. Results: A total of 1014 patients with ASD (median age at last follow-up, 22.8 years [interquartile range, 18.4-28.0 years]; 747 [73.7%] male; 902 [89.0%] white) and 2028 referents (median age at last follow-up, 22.4 years [interquartile range, 18.8-26.2 years]; 1494 [73.7%] male; 1780 [87.8%] white) participated in the study. Patients with ASD were significantly more likely to have clinically diagnosed bipolar disorder (hazard ratio [HR], 9.34; 95% CI, 4.57-19.06), depression (HR, 2.81; 95% CI, 2.45-3.22), and anxiety (HR, 3.45; 95% CI, 2.96-4.01) compared with referents. Among individuals with ASD, the estimates of cumulative incidence by 30 years of age were 7.3% (95% CI, 4.8%-9.7%) for bipolar disorder, 54.1% (95% CI, 49.8%-58.0%) for depression, and 50.0% (95% CI, 46.0%-53.7%) for anxiety. Among referents, cumulative incidence estimates by 30 years of age were 0.9% (95% CI, 0.1%-1.7%) for bipolar disorder, 28.9% (95% CI, 25.7%-32.0%) for depression, and 22.2% (95% CI, 19.3%-25.0%) for anxiety. Conclusions and Relevance: The findings suggest that individuals with ASD may be at increased risk for clinically diagnosed depression, anxiety, and bipolar disorder compared with age- and sex-matched referents. This study supports the importance of early, ongoing surveillance and targeted treatments to address the psychiatric needs of individuals with ASD.

Patterns of neuropsychological changes after general anaesthesia in young children: secondary analysis of the Mayo Anesthesia Safety in Kids study.

BACKGROUND: We hypothesised that exposure to multiple, but not single, procedures requiring general anaesthesia before age 3 yr is associated with a specific pattern of deficits in processing speed and fine motor skills. METHODS: A secondary analysis (using factor and cluster analyses) of data from the Mayo Anesthesia Safety in Kids study was conducted, in which unexposed, singly exposed, and multiply exposed children born in Olmsted County, MN, USA from 1994 to 2007 were sampled using a propensity-guided approach and underwent neuropsychological testing at ages 8-12 or 15-20 yr. RESULTS: In the factor analysis, the data were well fit to a five factor model. For subjects multiply (but not singly) exposed to anaesthesia, a factor reflecting motor skills, visual-motor integration, and processing speed was significantly lower [standardised difference of -0.35 (95% confidence interval {CI} -0.57 to -0.13)] compared with unexposed subjects. No other factor was associated with exposure. Three groups were identified in the cluster analysis, with 106 subjects (10.6%) in Cluster A (lowest performance in most tests), 557 (55.9%) in Cluster B, and 334 (33.5%) in Cluster C (highest performance in most tests). The odds of multiply exposed children belonging to Cluster A was 2.83 (95% CI: 1.49-5.35; P=0.001) compared with belonging to Cluster B; there was no other significant association between exposure status and cluster membership. CONCLUSIONS: Multiple, but not single, exposures to procedures requiring general anaesthesia before age 3 yr are associated with a specific pattern of deficits in neuropsychological tests. Factors predicting which children develop the most pronounced deficits remain unknown.

A unifying computational model of decision making.

Decision making has long been of interest as a descriptive phenomenon in psychology and as a generative one in artificial intelligence. Research ranges from general, descriptive models of heuristic decision making to detailed studies of decision parameters. This paper introduces a model that formalizes and integrates several descriptive models so that it can serve both as a framework for psychological models and as an algorithm for computational decision making. We set special focus on the instantiation of this model with respect to aggregating cue values by reviewing some methods from the field of computational social choice. To show its applicability in the context of artificial intelligence we present a case study of computational problem solving.

Neurocognitive Difficulties Among Youth with POTS within an Intensive Pain Rehabilitation Program.

OBJECTIVE: Adolescents and young adults (AYAs) with postural orthostatic tachycardia syndrome (POTS) commonly report cognitive difficulties, though there is limited information regarding the objective measurement of neurocognitive deficits in this population. This study described the rates of subjectively experienced and objectively measured neurocognitive difficulties and explored effects of medications on neurocognitive functioning among AYAs with POTS admitted to an intensive outpatient pain rehabilitation program. METHODS: Participants in a pain rehabilitation program diagnosed with POTS (N = 96; ages 12-22) were included in the study. Medical characteristics, reported cognitive complaints, and neurocognitive assessment results were collected through retrospective medical record review. We calculated descriptive statistics and Pearson's χ2 or Fisher's exact tests, where appropriate. RESULTS: While 96% of this sample reported subjective cognitive complaints, as a group, they performed in the Average range on standardized measures of intellectual functioning, attention, and memory. The majority did not demonstrate any normative (73%) or relative (54%) weaknesses in attention or memory. Those prescribed an antiepileptic (n = 19) were less likely to have visual-spatial memory weaknesses but more likely to have attention weaknesses. CONCLUSIONS: Despite a high frequency of reported cognitive difficulties, most AYAs with POTS did not demonstrate neurocognitive impairment on standardized, one-on-one assessment. Suggestions for further study of biopsychosocial contributors to neurocognitive difficulties and for clinical use of neurocognitive assessments in this population were provided.

Demonstration of Parent Training to Address Early Self-Injury in Young Children with Intellectual and Developmental Delays.

Individuals with intellectual and developmental disabilities (IDD) are at a high risk for engaging in self-injurious behavior (SIB). Prognosis is poor when SIB emerges early. Limited research exists on interventions teaching parents how to manage their young child's SIB. This investigation assessed the feasibility of adapting an applied behavior analytic parent training program with 11 parents of children 1-5 years of age with IDD and SIB. Quantitative and observational measures were used to assess outcomes; semi-structured interviews assessed caregiver satisfaction. Outcomes yielded preliminary data suggesting the adapted curriculum was feasible and acceptable to parents. Initial efficacy outcomes yielded decreases in SIB and observed negative parent-child interactions on pre- and post-measures. Qualitative data provided areas for further curriculum refinement.

A meta-analysis of indicated mental health prevention programs for at-risk higher education students.

This meta-analysis found empirical support for the effectiveness of indicated prevention programs for higher education students at risk for subsequent mental health difficulties based on their current subclinical levels of various presenting problems, such as depression, anxiety, or interpersonal difficulties. A systematic literature search identified 79 controlled published and unpublished interventions involving 4,470 college, graduate, or professional students. Programs were effective at post-intervention overall (ES = 0.49, CI [0.43, 0.55]), and for both targeted outcomes (ES = 0.58, CI [0.51, 0.64]) as well as additional nontargeted outcomes assessed in the studies (ES = 0.32, CI [0.25, 0.39]). Interventions compared with a no-intervention or a wait-list control (ES = 0.64, CI [0.57, 0.71], k = 68) demonstrated significantly larger effects overall than did interventions compared with an attention-placebo control (ES = 0.27, CI [0.11, 0.43], k = 11), although both were significant. Among the former group, modality and presenting problem emerged as significant moderators of intervention effectiveness, and among the 43 of these that assessed effectiveness at an average follow-up period of 35 weeks, the positive effects from intervention remained strong (ES = 0.59, CI [0.50, 0.68]). Overall, programs were fairly brief, attracted and retained students, were positively rated by students, and effective when administered by paraprofessionals as well as professionals. Current findings are promising and stimulate recommendations for improving future research, such as expanding the range of outcomes assessed, and clarifying moderators and mediators of intervention impact.

Explaining the pathway from familial and peer social support to disordered eating: Is body dissatisfaction the link for male and female adolescents?

OBJECTIVE: This study examined if familial and peer social support longitudinally predicted disordered eating for late adolescents in the transitional first year of college, and if body dissatisfaction mediated this relation. Gender differences between support types and disordered eating, and body dissatisfaction as a mediator, were also examined. PARTICIPANTS/METHODS: 651 late adolescent males and females (Mage=18.47) completed measures of social support at the end of the first semester of college and of disordered eating and body image approximately five months later, at the end of the first year. RESULTS: Lower levels of familial social support prospectively predicted greater disordered eating, but not greater body dissatisfaction, and lower levels of peer social support prospectively predicted greater body dissatisfaction but not greater disordered eating, above and beyond the other type of social support type, prior levels of body dissatisfaction, disordered eating, and BMI. Body dissatisfaction did not mediate the relation between familial social support and disordered eating; however, it did significantly mediate the non-significant relation between peer social support and disordered eating, which was further moderated by gender. CONCLUSION: These findings suggest that parental social support remains a significant predictor of disordered eating for late adolescents even after they transition to college, and has a stronger relation to disordered eating than peer support. In contrast, peer social support seems to be especially linked to feelings of body dissatisfaction and may be an avenue for intervention of this type of negative self-perception that is a risk factor for later disordered eating.

Modelling human problem solving with data from an online game.

Since the beginning of cognitive science, researchers have tried to understand human strategies in order to develop efficient and adequate computational methods. In the domain of problem solving, the travelling salesperson problem has been used for the investigation and modelling of human solutions. We propose to extend this effort with an online game, in which instances of the travelling salesperson problem have to be solved in the context of a game experience. We report on our effort to design and run such a game, present the data contained in the resulting openly available data set and provide an outlook on the use of games in general for cognitive science research. In addition, we present three geometrical models mapping the starting point preferences in the problems presented in the game as the result of an evaluation of the data set.

A Meta-Analysis of the Impact of Universal and Indicated Preventive Technology-Delivered Interventions for Higher Education Students.

The uses of technology-delivered mental health treatment options, such as interventions delivered via computer, smart phone, or other communication or information devices, as opposed to primarily face-to-face interventions, are proliferating. However, the literature is unclear about their effectiveness as preventive interventions for higher education students, a population for whom technology-delivered interventions (TDIs) might be particularly fitting and beneficial. This meta-analytic review examines technological mental health prevention programs targeting higher education students either without any presenting problems (universal prevention) or with mild to moderate subclinical problems (indicated prevention). A systematic literature search identified 22 universal and 26 indicated controlled interventions, both published and unpublished, involving 4763 college, graduate, or professional students. As hypothesized, the overall mean effect sizes (ESs) for both universal (0.19) and indicated interventions (0.37) were statistically significant and differed significantly from each other favoring indicated interventions. Skill-training interventions, both universal (0.21) and indicated (0.31), were significant, whereas non-skill-training interventions were only significant among indicated (0.25) programs. For indicated interventions, better outcomes were obtained in those cases in which participants had access to support during the course of the intervention, either in person or through technology (e.g., email, online contact). The positive findings for both universal and indicated prevention are qualified by limitations of the current literature. To improve experimental rigor, future research should provide detailed information on the level of achieved implementation, describe participant characteristics and intervention content, explore the impact of potential moderators and mechanisms of success, collect post-intervention and follow-up data regardless of intervention completion, and use analysis strategies that allow for inclusion of cases with partially missing data.

Examining stress and coping as a mediator for internalizing symptomatology: A comparison between sexual minority and majority first-year college students.

Sexual and gender minority (SGM) adolescents experience unique stressors and elevated internalizing symptoms. This study examines differences in coping styles between SGM and heterosexual adolescents and the potential mediating roles of stress and coping styles. Analyses indicated that SGM (N = 75) adolescents reported higher levels of internalizing symptoms (depression, anxiety, and distress), higher use of maladaptive coping styles (denial and blame), lesser use of adaptive coping styles (reframing and religion), and greater experiences of stress, compared to their heterosexual counterparts (N = 1702). Bootstrapping analyses revealed the relationship between sexual identity and internalizing symptoms measured approximately 3 months later was not mediated by stress and coping, adjusting for gender, age, and baseline symptomatology. Findings suggest that earlier adolescent differences in internalizing symptoms presage increasing symptomatology across the transition to college, and other mediators during the college transition explain the continued increases in internalizing symptoms.

Developmental Course and Determinants of Sleep Disturbances in Adolescents With Spina Bifida.

OBJECTIVES: To examine (1) trajectories of sleep disturbances in adolescents with spina bifida (SB) compared with a typically developing (TD) group over a 10-year period and (2) individual, family, and socioeconomic determinants of changes in sleep disturbances. METHODS: Participants were 68 families of youth with SB and 68 families of TD youth. Parent-report of adolescent sleep was collected every 2 years at 6 time points (T1: ages 8-9; T6: ages 18-19). Multiple informants and measures were used to examine internalizing, externalizing, and inattention symptoms, dyadic/family conflict, socioeconomic status (SES), and family income. RESULTS: Sleep disturbances increased over the 10-year period. Youth with SB had greater sleep disturbances during early adolescence. Greater preadolescent externalizing symptoms, greater parent-child and marital conflict, and lower SES predicted increased sleep disturbances. CONCLUSIONS: Sleep disturbances are common and persistent in adolescents with SB. Sleep assessment and management are important clinical and research priorities in this population.
