Sense of control, selective attention, cognitive inhibition, and psychosocial outcomes after Retraining and Control Therapy (ReACT) in pediatric functional seizures.

BACKGROUND: Differences in sense of control, cognitive inhibition, and selective attention in pediatric functional seizures (FS) versus matched controls implicate these as potential novel treatment targets. Retraining and Control Therapy (ReACT), which targets these factors, has been shown in a randomized controlled trial to be effective in improving pediatric FS with 82% of patients having complete symptom remission at 60 days following treatment. However, post-intervention data on sense of control, cognitive inhibition, and selective attention are not yet available. In this study, we assess changes in these and other psychosocial factors after ReACT. METHODS: Children with FS (N = 14, Mage = 15.00, 64.3% female, 64.3% White) completed 8 weeks of ReACT and reported FS frequency at pre and post-1 (7 days before and after ReACT). At pre, post-1, and post-2 (60 days after ReACT), all 14 children completed the Pediatric Quality of Life Inventory Generic Core Scales, Behavior Assessment System (BASC2), and Children's Somatic Symptoms Inventory-24 (CSSI-24), and 8 children completed a modified Stroop task with seizure symptoms condition in which participants are presented with a word and respond to the ink color (e.g., "unconscious" in red) to assess selective attention and cognitive inhibition. At pre and post-1, ten children completed the magic and turbulence task (MAT) which assesses sense of control via 3 conditions (magic, lag, turbulence). In this computer-based task, participants attempt to catch falling X's while avoiding falling O's while their control over the task is manipulated in different ways. ANCOVAs controlling for change in FS from pre- to post-1 compared Stroop reaction time (RT) across all time points and MAT conditions between pre and post-1. Correlations assessed the relationships between changes in Stroop and MAT performance and change in FS from pre- to post-1. Paired samples t-tests assessed changes in quality of life (QOL), somatic symptoms, and mood pre to post-2. RESULTS: Awareness that control was manipulated in the turbulence condition of the MAT increased at post-1 vs. pre- (p = 0.02, η2 = 0.57). This change correlated with a reduction in FS frequency after ReACT (r = 0.84, p < 0.01). Reaction time significantly improved for the seizure symptoms Stroop condition at post-2 compared to pre- (p = 0.02, η2 = 0.50), while the congruent and incongruent conditions were not different across time points. Quality of life was significantly improved at post-2, but the improvement was not significant when controlling for change in FS. Somatic symptom measures were significantly lower at post-2 vs. pre (BASC2: t(12) = 2.25, p = 0.04; CSSI-24: t(11) = 4.17, p < 0.01). No differences were observed regarding mood. CONCLUSION: Sense of control improved after ReACT, and this improvement was proportional to a decrease in FS, suggesting this as a possible mechanism by which ReACT treats pediatric FS. Selective attention and cognitive inhibition were significantly increased 60 days after ReACT. The lack of improvement in QOL after controlling for change in FS suggests QOL changes may be mediated by decreases in FS. ReACT also improved general somatic symptoms independent of FS changes.

Pain-Related Stigma and Its Associations With Clinical and Experimental Pain Severity in Youth With Chronic Musculoskeletal Pain Conditions.

OBJECTIVE: Many children with chronic musculoskeletal pain conditions experience stigma which can have negative downstream consequences. This study compares ratings of clinical pain (current pain intensity and pain interference), experimental pain (temporal summation, cold water tolerance, and cold pain intensity), and pain-related stigma among three groups of youth with rheumatic conditions. The relations among ratings of pain-related stigma and pain variables were explored. METHODS: Eighty-eight youth aged 8-17 years with a diagnosis of juvenile idiopathic arthritis (JIA = 32), juvenile fibromyalgia (JFM = 31), or non-specific chronic pain (NSCP = 25) completed measures of clinical pain ratings (average 7-day pain intensity, day of assessment pain (DoA), and pain interference), experimental pain (cold pain tolerance, cold pain intensity, and temporal summation of mechanical pain), and pain-related stigma. Data analysis compared pain-related stigma and pain ratings across the three groups and examined the relations among pain-related stigma and pain ratings. RESULTS: Youth with JFM reported higher ratings of clinical pain and pain-related stigma than their counterparts with NSCP or JIA. However, there were no differences in experimental pain. Pain-related stigma was associated with greater ratings of pain interference, particularly for those with JIA and NSCP. Pain-related stigma was also associated with greater average daily pain intensity but not DoA. CONCLUSION: Youth with medically unexplained pain report greater stigma and worse pain than their peers; thus, robust assessment of pain in this population is necessary. Future work should longitudinally explore the impact of pain-related stigma on pain outcomes and treatment responses.

Somatic Symptoms in Adolescents With an Ill Parent.

OBJECTIVE: Parent chronic illness may increase somatic symptomology risk in children. The current study examines this association in relation to a variety of chronic illnesses and also considers possible related parental and adolescent background factors. METHODS: Secondary analyses used longitudinal data from the University of North Carolina National Longitudinal Study of Adolescent to Adult Health. Interviews were used to assess demographics, adolescent somatic symptoms, living situation, and parental illness and general physical health. Somatic symptoms in adolescents with no ill parents (n = 2302 adolescents; Mage = 15.3) were compared with adolescents with ill mothers (n = 2336; Mage = 15.3), ill fathers (n = 1304; Mage = 15.3), or two ill parents (n = 3768; Mage = 15.3) using Poisson regression models. We also examined the role of living status, adolescent sex, and parent general physical health on somatic symptom outcomes. RESULTS: Elevated somatic symptoms were observed in adolescents with ill mothers (mean ratio [MR] = 1.15, p = .015) and with both parents ill (MR = 1.10, p < .001). Among adolescents with ill parents, females had more symptoms than males (ill mother: MR = 1.12, p < .001; ill father: MR = 1.23, p < .001; and both parents ill: MR = 1.23, p < .001). Poorer maternal physical health also increased somatic symptom risk (MR = 1.12, p = .02). Longitudinally, adolescents with ill mothers (MR = 1.14, p < .001), ill fathers (MR = 1.13, p < .001), or both parents ill (MR = 1.16, p < .001) had increased somatic symptom risk. Wave I somatic symptoms also increased future risk: ill mother (MR = 1.19, p < .001), ill father (MR = 1.22, p < .001), or both parents ill (MR = 1.20, p < .001). CONCLUSIONS: The results highlight that having an ill parent is a risk factor for adolescent somatic symptoms. In addition, other factors such as adolescent sex play an additional role in adolescent somatic symptoms.

Functional Neurological Symptom Disorder in Children and Adolescents within Medical Settings.

Pediatric functional neurological symptom disorder (FNSD or conversion disorder) is an often misunderstood but treatable condition that frequently presents in medical settings with unexplained symptoms. Although research regarding treatment of pediatric FNSD is increasing, it is still in its infancy and studies in pediatrics do not provide clear guidelines about which patients are most likely to benefit from various treatments. The role of pediatric psychologists may include consultation, assessment, treatment, program development, and providing education to patients, families, and healthcare colleagues in various disciplines. The purpose of this article is to provide a review of FNSD, discuss the importance of timely and accurate diagnosis, suggest how to present information to patients and families, and present options for treatment that are either supported by preliminary research or clinical experiences of the authors.

A Systematic Review of Somatic Symptoms in Children With a Chronically Ill Family Member.

OBJECTIVE: Somatization and functional somatic symptoms reflect conditions in which physical symptoms are not sufficiently explained by medical conditions. Literature suggests that these somatic symptoms may be related to illness exposure in the family. Children with a parent or sibling with a chronic illness may be particularly vulnerable to developing somatic symptoms. This study provides a systematic review of the literature on somatic symptoms in children with a chronically ill family member. METHODS: A systematic review (PROSPERO registry ID: CRD42018092344) was conducted using six databases (PubMed, EMBASE, PsychINFO, Scopus, CINAHL, and Cochrane) from articles published before April 5, 2018. All authors evaluated articles by title and abstract, and then by full-text review. Relevant data were extracted by the first author and reviewed by remaining authors. RESULTS: Twenty-seven unique studies met the criteria. Seventeen examined somatic symptoms in children with a chronically ill parent, and seven evaluated somatic symptoms in children with a chronically ill sibling. Three studies examined somatic symptoms in children with an unspecified ill relative. The strongest relationship between child somatization and familial illness was found with children with a chronically ill parent (13/17 studies). Evidence for somatic symptoms in children with an ill sibling was mixed (4/7 studies found a positive association). CONCLUSIONS: The literature on somatic symptoms in children suggests that parental illness is related to increased somatic symptoms in children. Research examining the effects of having a sibling with an illness on somatic symptoms is mixed. Several areas of future research are outlined to further clarify the relationship between familial chronic illness and somatic symptoms.

A review of functional neurological symptom disorder etiology and the integrated etiological summary model

Functional neurological symptom disorder (FNSD) is characterized by neurological symptoms that are unexplained by other traditional neurological or medical conditions. Both physicians and patients have limited understanding of FNSD, which is often explained as a physical manifestation of psychological distress. Recently, diagnostic criteria have shifted from requiring a preceding stressor to relying on positive symptoms. Given this shift, we have provided a review of the etiology of FNSD. Predisposing factors include trauma or psychiatric symptoms, somatic symptoms, illness exposure, symptom monitoring and neurobiological factors. Neurobiological research has indicated that patients with FNSD have a decreased sense of agency and abnormal attentional focus on the affected area, both of which are modulated by beliefs and expectations about illness. Sick role and secondary gain may reinforce and maintain FNSD. The integrated etiological summary model combines research from various fields and other recent etiological models to represent the current understanding of FNSD etiology. It discusses a potential causal mechanism and informs future research and treatment.

A Systematic Review of Sleep, Hypertension, and Cardiovascular Risk in Children and Adolescents.

PURPOSE OF REVIEW: Many of the risk factors for heart disease have recently been shown to develop during childhood such as left ventricular hypertrophy and fibrous plaque lesions. As risk for cardiovascular disease in children and adolescents has risen, sleep duration has decreased, and inadequate sleep in children and adolescents has been found to be associated with cardiovascular disease risk. The aims of this manuscript are to provide an updated systematic review of the literature assessing sleep, hypertension, and cardiovascular risk and evaluate the strength of the evidence based on the available research. RECENT FINDINGS: A systematic review was conducted using six databases from January 1, 2015 through March 9, 2018. We sought studies which looked at the relationship between sleep duration, sleep timing, or sleep quality and outcome variables of hypertension, inflammation, obesity, glucose or insulin, and lipids in children and adolescents. We found 24 studies which met our criteria. Nine studies included hypertension as an outcome variable; fifteen included obesity; thirteen included glucose or insulin; eight included lipids; and three included measures of inflammation. The existing literature on sleep and cardiovascular disease in children and adolescents is limited and relatively weak. Only one RCT was identified, and the overwhelming majority of studies had a high risk of bias. The strongest evidence of an association with sleep is with obesity, hypertension, and insulin sensitivity. Further research using more standardized methods and objective measures is needed to determine if a causal relationship truly exists between sleep and cardiovascular risk.

Assessment of Cardiovascular Health among Community-Dwelling Men with Incarceration History.

Returning to the community after incarceration is a particularly vulnerable time with significantly increased risk of death in the first 2 weeks. The elevated risk of death persists as long as 2 years, with cardiovascular disease (CVD) among the leading causes. African-Americans, especially African-American men, have higher rates of incarceration and community supervision (e.g., probation and parole) and an earlier onset of hypertension compared to Whites. Few studies have objectively assessed the cardiovascular health profile of criminal justice involved individuals. This study is designed to determine the cardiovascular health profile among men in community corrections and/or transitional housing, identify the prevalence of key CVD risk factors, and assess if risk varies by race/ethnicity. We recruited 100 adult men (mean age = 42.7, SD = 11.35, 60% White, 40% non-Hispanic White) with a history of incarceration in jail or prison of ≥ 6 months during their most recent incarceration and enrolled in a community corrections program. Using the American Heart Association's Life's Simple 7™ (LS-7), measures of each of the LS-7 components (body mass index, blood pressure, lipids, blood glucose, smoking, diet, and physical activity) were obtained, and LS-7 scores were generated for each measure using AHA-defined categories of poor (1 point), intermediate (2 points), and ideal (3 points) and summed to yield a total score ranging from poor for all (7 points) to ideal for all (21 points). Mann-Whitney U tests were performed to assess differences in LS-7 scores (poor, intermediate, ideal) by race/ethnicity. Additionally, an independent samples t test was conducted for race/ethnicity and LS-7 total score. Mann-Whitney U tests for LS-7 categories and race/ethnicity indicated a greater number of non-Whites had poor blood pressure (p < .01) and diet (p < .05) as compared to Whites. The independent samples t test demonstrated significantly lower LS-7 scores for non-Whites compared to Whites. To our knowledge, this is the first study to evaluate cardiovascular health among individuals with a history of incarceration using the LS-7 metric, which included objective measures for four of the seven LS-7 metrics. Non-Whites, which included African-Americans, Hispanics, and American Indians, were more likely than Whites to fall into the poor category for both diet and blood pressure and had significantly lower total LS-7 scores than Whites, indicating they have worse scores across all seven of the LS-7 measures. Similar to what is found among non-incarcerated samples, non-Whites with incarceration histories are at elevated risk for cardiovascular events relative to their White peers.

Optimizing outcomes when treating functional neurological disorder in acute care settings: case reports depicting the value of diagnostic precision and timely and appropriate psychological interventions using an interdisciplinary framework.

Introduction: Unexplained physical signs and symptoms represent a significant portion of patient presentations in acute care settings. Even in cases where a patient presents with a known medical condition, functional or somatic symptoms may complicate the diagnostic and treatment processes and prognostic outcome. One umbrella category for neurologically related somatic symptoms, functional neurological disorder (FND), presents as involuntary neurological symptoms incompatible with another medical condition. Symptoms may include weakness and/or paralysis, movement disorders, non-epileptic seizures, speech or visual impairment, swallowing difficulty, sensory disturbances, or cognitive symptoms (1). While FND presents as neuropsychiatric, providers commonly report feeling hesitant to diagnose these disorders. Inexperience or lack of appropriate education on relevant research regarding evidence-based practices or standard of practice (SOP) may result in over- or underperforming diagnostic workups and consultations, utilizing inappropriate medications, and failing to offer evidence-based psychological interventions. Being mindful of these challenges when treating patients presenting with functional symptoms in acute care settings can help to support and protect the patients and care team and appropriately control healthcare costs. Methods: The University of Alabama at Birmingham Medical Center identified cases representing categories of quality and safety problems that arise in treating FND in acute care settings. Patients signed a consent form to participate in the case report. The case information for each was presented without identifying information. Discussion: The cases highlight potential challenges when caring for patients presenting with FND in acute care settings. The challenges covered include over- or underutilization of diagnostic workups and consultation, over- or underutilization of psychopharmacological medications, and over- or undertreating a medical condition when a functional symptom is present. In each case, these lapses and errors caused the patient distress, additional treatments, care delays, and delayed symptom remission. Additionally, these challenges have direct and indirect fiscal costs, which can be mitigated with the appropriate education and training, resources, and protocols. Hospitals can benefit from system-wide SOP to improve the identification and management of FND to prevent harm to patients. An SOP commonly presents to specific specialties and ensures the appropriate diagnostic workup, consultations, and timely evidence-based interventions.

The effects of racial and socioeconomic disparities on time to diagnosis and treatment of pediatric functional seizures in the United States.

PURPOSE: The present study sought to assess the effects of racial and socioeconomic status in the United States on time to treatment and diagnosis of pediatric functional seizures (FS). METHODS: Eighty adolescents and their parent/guardian completed a demographics questionnaire and reported date of FS onset, diagnosis, and treatment. Paired samples t-tests compared time between FS onset and diagnosis, onset and treatment, and diagnosis and treatment based on race (White vs racial minority), annual household income (≤$79,999 vs ≥$80,000), maternal and paternal education (≤Associate's Degree vs Bachelor's Degree), and combined parental education (≤Post-graduate training vs Graduate degree). RESULTS: Adolescents with lower annual household income began treatment >6 months later than adolescents with greater annual household income (p = 0.049). Adolescents with lower maternal and paternal education (≤Associate's Degree vs Bachelor's Degree) began treatment >4 and ∼8.5 months later than adolescents with greater maternal and paternal education (p = 0.04; p = 0.03), respectively. Adolescents with lower maternal education also received a diagnosis >5 months later (p = 0.03). Adolescents without a mother or father with a graduate degree received a diagnosis and began treatment∼3 and >11 months later (p = 0.03; p = 0.01) than adolescents whose mother or father received a graduate degree, respectively. No racial differences were found. CONCLUSIONS: Adolescents with lower annual household income and/or parental education experienced increased duration between FS onset and treatment and diagnosis. Research is needed to clarify the mechanisms underlying this relationship, and action is needed to reduce these disparities given FS duration is associated with poorer prognosis and greater effects on the brain.

Effect of Sleep Restriction on Adolescent Cognition by Adiposity: A Randomized Crossover Trial.

Importance: Pediatric obesity is associated with impaired cognitive function; however, the mechanisms underlying this association demand assessment. Sleep may be a relevant moderator, as poor sleep predicts both increased adiposity and impaired cognitive function. Objective: To determine the effects of adiposity and sleep on adolescent cognitive function. Design, Setting, and Participants: This single-blind randomized crossover trial was conducted from September 2020 to October 2022. Parents or caregivers provided demographic information for adolescent participants. Body mass index percentile and bioelectrical impedance analysis assessed adiposity. Adolescents completed 2 actigraphy-confirmed sleep conditions, adequate and restricted, followed by in-person cognitive assessment. No additional follow-up was provided. Data collection for this population-based study took place in a behavioral medicine clinic in Birmingham, Alabama. A total of 323 participants were assessed for eligibility (ages 14-19 years and healthy). Of the 244 eligible adolescents, 157 declined participation. Eighty-seven were randomized and 26 dropped out postenrollment. The final sample included 61 adolescents, 31 with healthy weight and 30 with overweight or obesity. Data were analyzed from April to October 2023. Interventions: Following a 2-day washout period of adequate sleep, adolescents completed 2 sleep conditions: adequate (mean [SD] duration, 8 hours, 54 minutes [58.0 minutes]) and restricted (mean [SD] duration, 4 hours, 12 minutes [50.7 minutes]). Main Outcomes and Measures: The National Institutes of Health Cognitive Toolbox assessed global and fluid cognition, cognitive flexibility, working and episodic memory, attention, and processing speed. The Stroop Task assessed inhibition. Results: The final sample included 61 adolescents (mean [SD] age, 16.3 [1.6] years; 35 [57.4%] female). Restricted sleep predicted poorer global cognition scores (restricted mean [SD], 98.0 [2.8]; adequate mean [SD], 103.2 [2.9]), fluid cognition scores (restricted mean [SD], 94.5 [3.2]; adequate mean [SD], 102.0 [3.6]), and cognitive flexibility scores (restricted mean [SD], 84.8 [3.0]; adequate mean [SD], 92.8 [3.0]) for adolescents with overweight or obesity. No differences emerged for adolescents with healthy weight. Adolescents with overweight or obesity also had poorer attention scores (mean [SD], 80.0 [2.3]) compared to adolescents with healthy weight (mean [SD], 88.4 [SD, 2.3]) following restricted sleep. No differences emerged following adequate sleep. Findings were similar for total body fat percentage (TBF%); however, for adolescents with TBF% above 42, restricted sleep also predicted poorer processing speed, and the association between sleep and attention did not vary based on TBF%. Conclusions and Relevance: Adolescents with overweight or obesity may be more vulnerable to negative cognitive effects following sleep restriction. Improved sleep hygiene and duration in this group may positively impact their cognitive health. Trial Registration: ClinicalTrials.gov Identifier: NCT04346433.

Sleep and Inflammation during COVID-19 Virtual Learning in Adolescents with Overweight or Obesity.

(1) Background: Adolescents present as a high-risk group for a range of adverse physical health outcomes during the pandemic, including sleep and C-reactive protein (CRP) levels. As adolescents with overweight or obesity (OWOB) present as an even higher risk group, the present study assessed relationships between sleep and CRP levels before and during COVID-19 in adolescents with OWOB. (2) Methods: Fourteen adolescents with OWOB participated in a pre-COVID1, pre-COVID2, and during-COVID-19 lab visit, measuring sleep and CRP levels. The sample size was limited by the number of participants who provided data before COVID-19 and who were enrolled in virtual school during the recruitment phase. However, our power analyses indicated needing a minimum of 10 participants to achieve adequate power. Pre-COVID1, pre-COVID2, and during-COVID-19 normative expected CRP levels were calculated based on age, sex, race, and body mass index percentile-matched data. Analyses compared pre-COVID1 and pre-COVID2 sleep with during-COVID-19 sleep, during-COVID-19 sleep and during-COVID-19 CRP levels, during-COVID-19 CRP levels with normative expected during-COVID-19 CRP levels, change in CRP levels from pre-COVID1 and pre-COVID2 to during-COVID-19 with normative expected CRP levels during those time periods, and change in CRP levels before COVID-19 with change in CRP levels during COVID-19. (3) Results. During COVID-19, participants experienced decreased sleep efficiency (p = 0.001), later wake time (p < 0.001), longer time in bed (p = 0.021), and onset latency (p = 0.004), compared to pre-COVID1, and decreased sleep efficiency (p = 0.002), longer onset latency (p = 0.006), and later wake time (p < 0.001) and bedtime (p = 0.016) compared with pre-COVID2. During-COVID-19 CRP levels were positively correlated with during-COVID-19 wake times (p = 0.01) and times in bed (p = 0.008). During-COVID-19 CRP levels were greater than normative expected CRP levels (p < 0.001). CRP levels increased more from pre-COVID1 and pre-COVID2 to during-COVID-19 than normative expected changes in CRP levels (p < 0.003). Changes in CRP levels before and during COVID-19 were not significantly different. (4) Conclusions. These findings highlight the consequential effects of COVID-19, including impairments in sleep, on adolescents with OWOB. CRP levels increased more (~5 mg/L) during COVID-19 than normative expected change.

The Effects of COVID-19 Virtual Learning on Body Fat and Insulin Resistance in Adolescents with Overweight or Obesity.

(1) Background: COVID-19 virtual learning reduced structural supports for adolescent physical activity and diet, threatening metabolic health, especially in teens with overweight or obesity (OWOB). (2) Methods: Adolescents (N = 14) with OWOB completed fasting blood draws (measuring insulin resistance, IR) and Dual Energy X-Ray Absorptiometry (DXA, measuring total body fat percent, TBF%) pre-COVID-19 and during COVID-19. Changes in TBF% and IR were calculated (1) pre-COVID-19 and (2) from pre-COVID-19 to during COVID-19. Age and body mass index (BMI) percentile-matched data assessed normative changes across similar, non-COVID-19 time periods. Paired t-tests compared TBF% change pre- to during COVID-19 with (1) TBF% change pre-COVID19 and (2) TBF% normative change. Two ANCOVAs compared IR change pre- to during COVID-19 with (1) IR change pre-COVID-19 controlling for BMI z-score and difference in time between assessments and (2) normative change in IR controlling for sex/race. (3) Results: The TBF% change pre-COVID-19 and the normative change were similar. The TBF% increased more (~six percentage points) during COVID-19 compared to normative change (p < 0.01). During COVID-19, IR increased more (~2.5 units) than change pre-COVID-19 (p = 0.03) and increased more (~3.5 units) than normative change (p = 0.01). (4) Conclusions: TBF% and IR increased exponentially during COVID-19 in teens with OWOB compared to pre-COVID-19 and normative changes.

The Impact of Longitudinal Patterns of Adolescent Sleep Duration on Adult C-Reactive Protein (CRP), Waist-To-Height Ratio, and Body Mass Index (BMI) Among Black and White Individuals.

PURPOSE: To assess the impact of longitudinal adolescent sleep duration on adult C-reactive protein (CRP), waist-to-height ratio (WtHR), and body mass index (BMI) by race. METHODS: Participants (N = 2,399; Mage = 15.7; 40.2% male; 79.2% White, 20.8% Black; Grades 7-12 at Wave I) from the Add Health database provided self-reported sleep duration in Waves I-IV. During Wave V, CRP, WtHR, and BMI were objectively measured. Trajectory analysis was performed using a group-based modeling approach. Chi-square test determined racial differences between groups. General linear models determined relationships between trajectory group, race, and group/race interaction with Wave V CRP, WtHR, and BMI. RESULTS: Three sleep trajectories emerged: Group 1 "shortest" (24.4%), Group 2 "stable recommended" (67.6%), and Group 3 "varied" (8%). Black individuals and older individuals were more likely to be in Group 1 compared with Group 2. Regardless of race, individuals with patterns of sleep duration increasing to above what is recommended across waves (Group 3) had elevated CRP. Individuals with stable patterns of adequate sleep (Group 2) had lower WtHR. Black individuals with consistently stable patterns of adequate sleep duration had lower BMI compared to those with low sleep duration. DISCUSSION: Black individuals were more likely to obtain chronically short sleep during the transition from adolescence to adulthood, highlighting a significant health disparity. Poor longitudinal sleep predicted elevated CRP and WtHR. Sleep only impacted BMI for Black individuals. This may relate to racial differences in BMI measurement.

Treatment Approaches for Functional Neurological Disorders in Children.

Purpose of Review: Functional neurological disorder (FND) is a multi-network brain disorder that encompasses a broad range of neurological symptoms. FND is common in pediatric practice. It places substantial strains on children, families, and health care systems. Treatment begins at assessment, which requires the following: the medical task of making the diagnosis, the interpersonal task of engaging the child and family so that they feel heard and respected, the communication task of communicating and explaining the diagnosis, and the logistical task of organizing treatment. Recent Findings: Over the past decade, three treatment approaches-Retraining and Control Therapy (ReACT), other cognitive-behavioral therapies, and multidisciplinary rehabilitation-have been evaluated in the USA, Canada, and Australia. Of children treated in such programs, 63 - 95% showed full resolution of FND symptoms. The common thread across the programs is their biopsychosocial approach-consideration of biological, psychological, relational, and school-related factors that contribute to the child's clinical presentation. Summary: Current research strongly supports a biopsychosocial approach to pediatric FND and provides a foundation for a stepped approach to treatment. Stepped care is initially tailored to the needs of the individual child (and family) based on the pattern and severity of FND presentation. The level of care and type of intervention may then be adjusted to consider the child's response, over time, to treatment or treatment combinations. Future research is needed to confirm effective treatment targets, to inform the development of stepped care, and to improve methodologies that can assess the efficacy of stepped-care interventions.

Psychiatric and personality factors in pediatric functional seizures: A prospective case-control study.

PURPOSE: This study assessed psychiatric and personality characteristics in relation to pediatric functional seizures (FS). METHODS: In a 1:1 prospectively matched-control study design, children with documented FS (confirmed via video EEG; ages 13-18) were matched to controls (MCs) on income, sex, race, and age. Primary outcomes were Behavior Assessment System for Children, Second Edition (BASC-2) and Millon Adolescent Clinical Inventory (MACI). Secondary measures included questionnaires assessing trauma, somatization, body awareness and quality of life (QOL). T-tests investigated differences between groups on T-scores. Due to lack of significant outcomes, an experimental analysis was conducted assessing differences in number of clinically elevated BASC-2 and MACI scores between groups. Binary logistic regressions determined the influences of clinically elevated scores on likelihood participants have FS. T-tests assessed differences on secondary measures. RESULTS: Participants included 84 children, 42 with FS and 42 MCs (Children with FS: Meanage=15.4, Interquartile Rangeage=3; 73.5% female; 59.5% white). Children with FS had greater parent-reported somatization (t(23)=5.67, p<0.001) on BASC-2, greater somatization on CSSI-24 (t(35)=6.83, p<0.001), and poorer QOL (t(41)=-6.22; p<0.001) than MCs. There were no differences in clinically elevated BASC-2 or MACI scores compared to MCs and clinically elevated scores did not influence likelihood participants have FS. CONCLUSIONS: Children with FS had greater somatization and poorer QOL but similar rates of psychiatric symptoms, trauma, and maladaptive personality traits compared to MCs. Psychiatric or personality factors did not predict likelihood of FS. Explanations of pediatric FS should consider novel contributors to FS rather than relying solely on a psychiatric etiology.

Sense of control, selective attention and cognitive inhibition in pediatric functional seizures: A prospective case-control study.

PURPOSE: To date, laboratory-based experimental behavioral methods have not been used to identify factors associated with pediatric functional seizures (FS), leaving a critical gap for effective treatment development. METHODS: Children ages 13-18 with video-EEG-confirmed FS were matched to controls (MCs) based on income, sex, race, and age. A modified Stroop task which included a condition requiring participants to report the ink colors in which seizure symptom words were written (e.g., "shaking" in blue) measured selective attention and cognitive inhibition through response time. The magic and turbulence task assessed sense of control in three conditions (magic, lag, turbulence). Children with FS were asked to report premonitory symptoms predicting FS. RESULTS: Participants included 26 children with FS and 26 MCs (Meanage=15.2, 74% female, 59% white). On Stroop, children with FS had a slower reaction time (Mean=1193.83) than MCs (Mean=949.26, p = 0.022) for seizure symptom words. Children with FS had significantly poorer sense of control in the turbulence condition of the magic and turbulence task (Mean=-3.99, SD=8.83) than MCs (Mean=-11.51, SD=7.87; t(20)=-2.61, p =0.017). Children with FS (Mean=-1.80, SD=6.54) also had significantly poorer sense of control in the magic condition than MCs (Mean=-5.57, SD=6.01; p =0.028). Ninety-eight percent of patients endorsed premonitory symptoms. CONCLUSION: Compared with MCs, children with FS have (1) poorer selective attention and cognitive inhibition when presented with seizure-related information and (2) lower sense of control (i.e. poorer awareness that their control was manipulated). Premonitory symptoms were common. Sense of control, selective attention, and inhibition may be novel treatment targets for FS intervention.

One-year follow-up of treatment outcomes and patient opinions of Retraining and Control Therapy (ReACT) for pediatric functional seizures.

Retraining and Control Therapy (ReACT), a short-term treatment for pediatric functional seizures (FS), has been demonstrated to improve FS in children compared to supportive therapy. However, long-term maintenance of FS-reduction after ReACT is unclear. This study aims to assess seizure frequency 1 year after ReACT and determine patient and parents' opinions of ReACT. Children with functional seizures who previously completed ReACT and their parents were asked to report 30-day FS frequency 1 year after completing ReACT. They also reported if ReACT was helpful. Paired samples t-tests were used to compare FS frequency before ReACT to 1 year after and to compare FS frequency in 30 days after ReACT to 1 year after. Fourteen children (Meanage = 15.43) and their parents participated. Seven-day FS frequency for patients at 1-year follow-up (Mean = 0.15) was significantly lower than 7-day FS frequency pre-ReACT (Mean = 5.62; p = 0.005). No differences were found when comparing FS frequency during 30 days post-ReACT (Mean = 0.29) and in 30 days before 1-year follow-up (Mean = 0.71). This study confirms long-term maintenance of FS-reduction after ReACT and supports the efficacy of targeting FS directly as opposed to mood or stress for reducing FS. Additionally, children and parents believe ReACT is beneficial.

Identifying and evaluating novel treatment targets for the development of evidence-based interventions for functional neurological disorder.

Historically, functional neurological disorder (FND) has been described in psychodynamic terms as the physical manifestation of psychological distress. It is often explained to patients and caregivers as the result of anxiety, stress, trauma or other psychiatric comorbidities. However, recent evidence indicates that targeting mood and stress is not equivalent to the treatment of FND and may have limited to no effect on FND symptoms. Given the few randomized controlled trials for FND treatments and the limited evidence of mood and stress as effective treatment targets, the identification and evaluation of novel treatment targets or mediators is an area of great opportunity and should be the focus of future research. Identifying and targeting modifiable disease mechanisms directly as opposed to only treating psychiatric comorbidities may result in greater efficacy in treating FND symptoms, better patient outcomes and lower healthcare costs. Several novel mechanisms have been identified that warrant additional investigation as potential treatment targets including abnormal attentional focus on the affected area, beliefs and expectations about illness, impairments in habituation, and decreased sense of control over actions. Future intervention studies should take a mechanism-based approach and utilize valid and reliable measures or specific biomarkers to determine whether improvements in FND symptoms are associated with changes in the treatment targets. This transdiagnostic approach will allow researchers to translate the novel mechanistic outcomes emerging from neurophysiological and neuroscience studies into new or improved evidence-based approaches to FND treatment and prevention.

Changing the culture of care for children and adolescents with functional neurological disorder.

As members of a multidisciplinary team of professionals who treat children and adolescents with functional neurological (conversion) disorder (FND), we highlight the pressing need to develop an FND-informed culture of care that takes into account recent advances in our understanding of this group of patients. Stories of clinical encounters in health care settings from around the world-told by children and adolescents with FND, their parents, and health professionals-portray an outdated culture of care characterized by iatrogenic stigma, erosion of empathy and compassion within the clinician-patient relationship, and a lack of understanding of FND and its complex neurobiology. After a brief exploration of the outdated culture, we share our counterstories: how we and our colleagues have worked, and continue to work, to create an FND-informed culture in the health systems where we practice. We discuss the therapeutic use of child-friendly language. We also discuss a range of structural, educational, and process interventions that can be used to promote FND-informed beliefs and attitudes, FND-informed clinician-patient encounters, and FND-informed referral processes, treatment pathways, and therapeutic interventions.
