Inattention and hyperactivity in association with autism spectrum disorders in the CHARGE study

BackgroundAttention deficits in young children with autism spectrum disorder (ASD) are not well understood. This study sought to determine: 1) the prevalence of ADHD symptoms in young children with ASD, typical development (TD), and developmental delay (DD) and 2) the association between ADHD symptoms and cognitive and behavioral functioning in children with ASD.MethodADHD symptoms, defined according to Aberrant Behavior Checklist (ABC) hyperactivity subscale scores, were compared across children aged 2–5 from a large case-control study with ASD (n = 548), TD (n = 423), and DD (n = 180). Inattention and hyperactivity items within this subscale were also explored. Within the ASD group, linear and logistic regression were used to examine how ADHD symptoms were associated with cognition as assessed by the Mullen Scales of Early Learning and adaptive functioning as assessed by the Vineland Adaptive Behavior Scales.ResultsMean hyperactivity subscale scores were lowest in children with TD (mean = 3.19), higher in children with DD (12.3), and highest in children with ASD (18.2; between-group p < 0.001). Among children with ASD, significant associations were observed with higher ADHD symptoms and poorer adaptive and cognitive functioning (adjusted beta for hyperactivity score in association with: Vineland composite = −5.63, p = 0.0005; Mullen visual reception scale = −2.94, p = 0.02; for the highest vs. lowest quartile of hyperactivity score, odds of lowest quintile of these scores was approximately doubled). Exploratory analyses highlighted associations with inattention-related items specifically.ConclusionThese results suggest ADHD symptoms may play a key role in the functioning of young children with ASD.     

Social anxiety and self-concept in children with epilepsy: A pilot intervention study

PurposeThe purpose of this study was to assess the impact of a cognitive behavioral therapy (CBT) anxiety intervention on social phobia, social skill development, and self-concept.MethodFifteen children with epilepsy and a primary anxiety disorder participated in a CBT intervention for 12 weeks plus a 3-month follow-up visit. Children were assessed at baseline, week 7, week 12, and 3 months post treatment to measure changes in social phobia using the Screen for Child Anxiety Related Emotional Disorders (SCARED). Self-concept was also assessed by using the Piers-Harris Children's Self-Concept Scale II (Piers-Harris 2).ResultsThere was a significant reduction in symptoms of social phobia and improved self-concept at the end of the 12-week intervention and at the 3 month follow-up. Repeated measures ANOVA's of child ratings revealed significant change over time on the SCARED-Social Phobia/Social Anxiety subscale score (p = 0.024). In terms of self-concept, significant change over time was detected on the Piers-Harris 2-Total score (p = 0.015) and several subscale scores of Piers-Harris 2, including: Physical Appearance and Attributes (p = 0.016), Freedom from Anxiety (p = 0.005), and Popularity (p = 0.003).ConclusionThis pilot investigation utilized an evidenced based CBT intervention to reduce symptoms of social phobia, which in turn provided a vehicle to address specific social skills improving self-concept in children with epilepsy.     

Prenatal exposure to the organophosphate pesticide chlorpyrifos and childhood tremor

BackgroundThe organophosphate insecticide chlorpyrifos (CPF), widely used for agricultural purposes, has been linked to neurodevelopmental deficits. Possible motor effects at low to moderate levels of exposure have not been evaluated.MethodsPrenatal exposure to CPF was measured in umbilical cord blood in a sample of 263 inner-city minority children, who were followed prospectively. At approximately 11 years of age (mean age 10.9 ± 0.85 years, range = 9.0–13.9), during a neuropsychological assessment, children were asked to draw Archimedes spirals. These were rated by a senior neurologist specializing in movement disorders who was blind to CPF exposure level.ResultsCompared to all other children, those with prenatal CPF exposure in the upper quartile range (n = 43) were more likely to exhibit mild or mild to moderate tremor (≥1) in either arm (p = 0.03), both arms (p = 0.02), the dominant arm (p = 0.01), and the non-dominant arm (p = 0.055). Logistic regression analyses showed significant CPF effects on tremor in both arms, either arm, the dominant arm (p-values <0.05), and the non-dominant arm (p = 0.06), after adjustment for sex, age at testing, ethnicity, and medication.ConclusionPrenatal CPF exposure is associated with tremor in middle childhood, which may be a sign of the insecticide's effects on nervous system function.     

Assessment of COVID-19 trauma responses. Who has been more traumatized during the pandemic?

Background and ObjectiveTo evaluate the effect of cognitive and sociodemographic characteristics of healthcare and non-healthcare workers on their traumatic responses to the COVID-19 pandemic.MethodsData were collected using an online survey between August-September 2020. The survey included the following scales: Beck Anxiety Inventory (BAI), Anxiety Sensitivity Index (ASI), and Impact of Event Scale-Revised (IES-R). Traumatic responses were categorized into three types: avoidance (IES-R_A), intrusion (IES-R_I), and hyperarousal (IES-R_H).ResultsThe study included a total of 672 participants, comprised of 399 (59.4%) men, and 273 (40.6%) women with a mean age of 39.25 ± 933 years. The results indicated that women had higher IES-R_I (r = .5.78, p < 0.001), IES-R_A (r = 4.47, p < 0.001), and IES-R_H (r = .5.20, p < 0.001) scores compared to men. Patients with a history of psychiatric diseases had significantly higher IES-R_I (r = ?3.82, p < 0.001), IES-R_A (r = ?2.00, p < 0.05), and IES-R_H (r = ?4.06, p < 0.001) scores compared to patients with no history of psychiatric diseases. Non-healthcare workers had significantly higher IES-R_A (r = ?2.69, p < 0.01) scores compared to healthcare workers.ConclusionFemale gender and a positive history of psychiatric diseases were found to lead to an increase in the frequency of all three traumatic responses to COVID-19. Contrary to expectation, being a healthcare worker was not found as a factor facilitating trauma response formation in our study.     

The association of somatic arousal with the symptoms of upper airway resistance syndrome

ObjectivesWe tested the hypothesis that the symptoms of upper airway resistance syndrome (UARS) are manifestations of chronic stress. To accomplish this, we utilized the score on a self-report questionnaire for somatic arousal (a component of stress) to compare somatic arousal between UARS patients and healthy controls and, among all participants, to correlate the level of somatic arousal with the severity of UARS symptoms.MethodsWe administered the Mood and Anxiety Symptom Questionnaire anxious arousal subscale (MASQaas; a 17-item questionnaire with increasing levels of arousal scored 17–85) to 12 UARS patients and 12 healthy controls and compared scores between groups. For all participants, we correlated the MASQaas scores with scores for the Epworth Sleepiness Scale (ESS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) scale, Pittsburgh Sleep Quality Index (PSQI), SF-36 Health Survey, and Perceived Deficits Questionnaire (PDQ; assessing cognitive function).ResultsCompared to healthy controls, UARS patients demonstrated increased somatic arousal (MASQaas scores of 18 ± 2 and 28 ± 7, respectively; p < 0.0001). For all participants, the MASQaas scores correlated significantly with scores of the ESS (r = 0.64; p = 0.0008), the FACIT-Fatigue scale (r = −0.89; p < 0.0001), the PSQI (r = 0.70; p = 0.0002), SF-36 Physical component (r = −0.78; p < 0.0001), SF-36 Mental component (r = −0.74; p < 0.0001), and the PDQ (r = 0.89; p < 0.0001).ConclusionsOur findings suggest that UARS patients have increased levels of the stress component, somatic arousal, proportionate to the severity of their symptoms.     

Assessment of physical fitness and exercise tolerance in children with developmental coordination disorder

Children with developmental coordination disorder (DCD) have been shown to be less physically fit when compared to their typically developing peers. The purpose of the present study was to examine the relationships among body composition, physical fitness and exercise tolerance in children with and without DCD. Thirty-seven children between the ages of 7 and 9 years participated in this study. Participants were classified according to results obtained on the Movement Assessment Battery for Children (MABC) and were divided in 2 groups: 19 children with DCD and 18 children without DCD. All children performed the following physical fitness tests: The five-jump test (5JT), the triple-hop distance (THD) and the modified agility test (MAT). Walking distance was assessed using the 6-min walking test (6MWT). Children with DCD showed higher scores than children without DCD in all MABC subscale scores, as well as in the total score (p < 0.001). Participants with DCD were found to perform significantly worse on the MAT (p < 0.001), the THD (p < 0.001) and 5JT (p < 0.05). Moreover, children with DCD had poorer performance on the 6MWT than children without DCD (p < 0.01). Our results found significant correlations among body mass index (BMI), THD (r = 0.553, p < 0.05), 5JT (r = 0.480, p < 0.05) and 6MWT (r = 0.544, p < 0.05) only in DCD group. A significant correlation between MAT and 5JT (r = −0.493, p < 0.05) was found. Similarly, THD and 5JT (r = 0.611, p < 0.01) was found to be correlated in children with DCD. We also found relationships among 6MWT and MAT (r = −0.522, p < 0.05) and the 6MWT and 5JT (r = 0.472, p < 0.05) in DCD group. In addition, we found gender specific patterns in the relationship between exercise tolerance, explosive strength, power, DCD, and BMI. In conclusion, the present study revealed that BMI was indicative of poorer explosive strength, power and exercise tolerance in children with DCD compared to children without DCD probably due to a limited coordination on motor control.     

Sensorimotor function in preschool-aged children with expressive language disorder

AimThe aim of the study was to evaluate functional motor performance and haptic object recognition in 5-year-old children with mild expressive language disorder (ELD) in comparison with age- and gender-matched healthy children.MethodsThe subjects were classified by speech-language pathologist using The Reynell Developmental Language Scales III and Boehm Test of Basic Concepts: Preschool as children with mild ELD (n = 29, incl. 23 boys and 6 girls) and children with typical language development as controls (n = 29, incl. 23 boys and 6 girls). The children were examined for manual dexterity, ball skills, static and dynamic balance by Movement-ABC, haptic object recognition (HOR), hand-grip strength (HGS) and vertical jumping performance.ResultsChildren with mild ELD demonstrated significantly higher scores (i.e., inferior performance) in all subtests of M-ABC (all p values <0.05), in haptic object recognition (p < 0.01) and vertical jumping height (p < 0.05) compared to controls. However, no statistically significant differences (p > 0.05) emerged from HGS. Boys with mild ELD demonstrated higher results in impairment score (p < 0.001), ball skills (p < 0.01) and balance (p < 0.01) of M-ABC, as well as in HOR (p < 0.05). Girls with mild ELD showed higher impairment score (p < 0.05) with lower percentile (p < 0.05) in M-ABC, indicating inferior motor performance, and lower HGS for the non-dominant hand (p < 0.05). Seven out of 29 (24.1%) children with mild ELD had definite or borderline motor difficulties, while only one child in control group (3.4%) demonstrated borderline motor difficulties.ConclusionsChildren with mild expressive language disorder do not perform as well as controls in tests of functional motor skills, but their results in tests demanding maximal muscle force generation are in level with typically developing children. Boys and girls with mild ELD demonstrated higher impairment scores in M-ABC, indicating the need to follow their overall development more closely.     

Different attachment styles correlate with mood disorders in adults with epilepsy or migraine

PurposeInterpersonal relationships are viewed as important contexts within which psychopathology emerges and persists or desists. Attachment theory describes the dynamics of long-term relationships between humans especially in families and lifelong friendships. The present study was aimed at investigating attachment styles in adult patients with epilepsy as compared to subjects with migraine and their potential correlates with a history of mood disorders.MethodsA consecutive sample of 219 adult outpatients with epilepsy (117) or migraine (102) was assessed with the Attachment Style Questionnaire (ASQ).ResultsPatients with epilepsy and a lifetime history of mood disorders presented elevated scores for Need for approval (p < 0.001) and Preoccupation with relationships (p < 0.001). Age correlated with the Relationships as secondary (r = 0.322; p < 0.001) and Need for approval (r = 0.217; p = 0.019) subscales while age at onset correlated only with Relationships as secondary (r = 0.225; p = 0.015). Seizure-free patients presented lower scores for Need for approval (p = 0.003). Patients with migraine and a lifetime history of mood disorders presented lower scores in Confidence (p = 0.002) and higher scores in Discomfort with closeness (p = 0.026).ConclusionsAn anxious–preoccupied attachment correlated with mood disorders in epilepsy while it was an avoidant pattern in migraine. Our results bring further data on the role of psychological variables in mood disorders in epilepsy. Further studies will allow early identification of patients at risk and the development of preventive strategies.     

Risk factors associated with short sleep duration among Chinese school-aged children

ObjectivesTo examine risk factors regarding short sleep duration among Chinese school-aged children.MethodsA random sample of 20,778 children aged around 5–11 years participated in a cross-sectional survey, which was conducted in eight cities of China in 2005. A parent-administered questionnaire was used to collect information on children’s sleep duration and possible related factors from eight domains. Short sleep duration was defined as total sleep duration <9 h per day.ResultsIn all, 28.3% of the sampled children slept <9 h per day. The multivariate logistic regression identified, after adjusting for demographic and socioeconomic variables, factors associated with short sleep duration: more television viewing during weekdays (OR = 1.21, p = 0.004), more frequent computer/internet using (OR = 1.17, p = 0.006), earlier school starting time (OR = 1.10, p = 0.020), more time on homework during weekdays (OR = 1.66, p < 0.001) and weekends (OR = 1.14, p = 0.001), poor bedtime hygiene (e.g., having drinks with caffeine after 6:00PM [OR = 1.22, p < 0.001], doing exciting activities during bedtime [OR = 1.16, p < 0.001], and irregular bedtime [OR = 1.55, p < 0.001]), and shorter sleep duration of parents (mother: OR = 1.31, p < 0.001 for sleep duration <6 h and OR = 1.24, p = 0.006 for 6–8 h; father: OR = 1.52, p < 0.001 for <6 h and OR = 1.19, p < 0.001 for 6–8 h).ConclusionsFactors associated with sleep duration covered multidimensional domains among school-aged children. Compared to sleep environments and chronic health problems, school schedules, lifestyle patterns, and parents’ sleep habits had greater impact on children’s sleep duration, indicating the existing chronic sleep loss in school children could be, at least partly, intervened by reducing the use of visual technologies, by changing the school schedules, by improving the sleep hygiene routine, and by regulating parents’ sleep habits.     

Adult separation anxiety disorder in complicated grief: an exploratory study on frequency and correlates

IntroductionComplicated grief (CG) has been the subject of increasing attention in the past decades but its relationship with separation anxiety disorder (SEPAD) is still controversial. The aim of the current study was to explore the prevalence and clinical significance of adult SEPAD in a sample of help-seeking individuals with CG.Methods151 adults with CG, enrolled in a randomized controlled trial comparing the effectiveness of (CG) treatment to that of interpersonal therapy, were assessed by means of the Inventory of Complicated Grief (ICG), the Structured Clinical Interview for DSM-IV, the Hamilton Rating Scale for Depression (HAM-D), the Work and Social Adjustment Scale (WSAS), the Adult Separation Anxiety Questionnaire (ASA-27), the Grief Related Avoidance Questionnaire (GRAQ), the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), and the Impact of Events Scale (IES).Results104 (68.9%) individuals with CG were considered to have SEPAD (ASA-27 score ≥22). Individuals with SEPAD were more likely to have reported a CG related to the loss of another close relative or friend (than a parent, spouse/partner or a child) (p = .02), as well as greater scores on the ICG (p = <.001), PDEQ (p = .004), GRAQ (p < .001), intrusion (p < .001) and avoidance (p = <.001) IES subscales, HAM-D (p < .001) and WSAS (p = .006). ASA-27 total scores correlated with ICG (p < .0001), PDEQ (p < .001) GRAQ (p < .0001) scores and both the IES intrusion (p < .0001) and IES avoidance (p < .0001) subscale scores. People with SEPAD had higher rates of lifetime post-traumatic stress disorder (PTSD) (p = .04) and panic disorder (PD) (p = .01).ConclusionsSEPAD is highly prevalent among patients with CG and is associated with greater symptom severity and impairment and greater comorbidity with PTSD and PD. Further studies will help to confirm and generalize our results and to determine whether adult SEPAD responds to CG treatment and/or moderates CG treatment response.     

Orthorexia Nervosa in Turkish dietitians and dietetic students

ObjectivesOrthorexia Nervosa (ON) is characterized by a pathological obsession with healthy eating, and dietetic majors may have a potential risk of developing ON due to their occupation that necessitates consideration of optimal food choices. This study aimed to determine the prevalence of ON among a large sample of dietitians and dietetic students in Turkey and to investigate the association of ON with socio-demographic features and eating attitudes within the whole sample.MethodsParticipants (n = 1429) completed a self-administered online survey that featured socio-demographic characteristics, the Orthorexia Nervosa Questionnaire (ORTO-11), and the Eating Attitudes Test-26 (EAT-26). Scores on the ORTO-11 and EAT-26 determined the prevalence of ON and disordered eating behaviors, respectively.ResultsThe prevalence of ON among Turkish dietetic majors was 59.8% with a higher ratio in dietetic students (63.8%) than dietitians (52.9%) (P < 0.001). While graduation was associated with 33.1% lower odds of ON (P = 0.006), eating disorders could increase the ON risk approximately five times (P < 0.001). Furthermore, the greater total and subscale (dieting, bulimia, and oral control) scores of EAT-26 were associated with higher ON tendency (P < 0.001), even after adjustment for potential confounders.ConclusionsOur findings may shed light on the relevance of developing strategies to reduce the prevalence of ON in the dietetic population but need to be supported by further longitudinal and prospective studies.     

The executive profile of children with Benign Epilepsy of Childhood with Centrotemporal Spikes and Temporal Lobe Epilepsy

RationaleBenign Epilepsy of Childhood with Centrotemporal Spikes (BECTS) and temporal lobe epilepsy (TLE) represent two distinct models of focal epilepsy of childhood. In both, there is evidence of executive dysfunction. The purpose of the present study was to identify particular deficits in the executive function that would distinguish children with BECTS from children with TLE.MethodsWe prospectively evaluated 19 consecutive children and adolescents with TLE with hippocampal sclerosis (HS) (57.9% male; mean 11.74 years [SD 2.05]; mean IQ 95.21 [SD 15.09]), 19 with BECTS (36.8% male; mean 10.95 years [SD 2.33]; mean IQ 107.40 [SD 16.01]), and 21 age and gender-matched controls (33.3% male; mean 11.86 years [SD 2.25]; mean IQ 108.67 [15.05]). All participants underwent a neuropsychological assessment with a comprehensive battery for executive and attentional functions. We used ANOVA and chi-square to evaluate differences on demographic aspects among groups (BECTS, TLE-HS, and control groups). Group comparisons on continuous variables were complemented by MANOVA and Bonferroni posthoc comparisons.ResultsPatients with BECTS had worse performance than controls in: Matching Familiar Figures Test, time (p = 0.001); Matching Familiar Figures Test, time × errors index (p < 0.001); Verbal Fluency for foods (p = 0.038); Trail Making Test, part B time (p = 0.030); Trail Making Test, part B number of errors (p = 0.030); and WCST, number of categories achieved (p = 0.043). Patients with BECTS had worse performance than patients with TLE-HS on Matching Familiar Figures Test, time (p = 0.004), and Matching Familiar Figures Test, time × errors index (p < 0.001). Patients with TLE-HS had worse performance than controls on the following tests: Verbal Fluency for foods (p = 0.004); Wisconsin Card Sorting Test, the number of categories achieved (p < 0.001); and Wisconsin Card Sorting Test, the number of perseverative errors (p = 0.028). Patients with TLE-HS had worse performance than patients with BECTS on Digit Backward (p = 0.002); and the Wisconsin Card Sorting Test, the number of perseverative errors (p < 0.001).ConclusionsPatients with TLE and BECTS present distinct cognitive profiles. Patients with TLE-HS had worse performance in mental flexibility, concept formation, and working memory compared to BECTS. Patients with BECTS had worse inhibitory control compared to children with TLE-HS. Both TLE-HS and BECTS had a higher number of errors on an inhibitory control test. However, patients with BECTS had a slower mental processing even when compared to patients with TLE-HS. Rehabilitation programs for children with epilepsy must include children with benign epilepsies and must take into account the epileptic syndrome and its particular neurocognitive phenotype.     

Epilepsy,school readiness in Canadian children: Data from the National Longitudinal Study of Children and Youth (NLSCY)

PurposeUtilizing data from the National Longitudinal Survey of Children and Youth (NLSCY) we evaluated the association between childhood epilepsy and health impairments on measures of school readiness employed in the survey.MethodsStandard scores on the Peabody Picture Vocabulary Test-Revised (PPVT-R) were employed in a regression analysis to compare scores in children with and without epilepsy. We also examined the effect of impairments in any of the 8 domains of the Health Utilities index (HUI) on test scores.ResultsA total sample size of 39,130 children (20,044 males, and 19,086 female were included in the analysis, 33,560 children were administered the PPVT-R at a mean age of 4.5 years. There were 70 children with epilepsy, 21 had a score of 1 on the HUI, 21 were assessed to have a HUI < 1 (signifying health impairments in one or more of the 8 domains). In the remainder, the PPVT scores were missing. Using the Ordinary Least Squares (OLS) regression for continuous outcomes model for PPVT-R scores as the outcome variable, females scored 1.1 points higher (β = 1.1, 95%CI 0.755, 1.444, p = 0.000), children without epilepsy and HUI score of <1 scored 3.84 points lower (β = −3.843 95%CI −4.232, −3.452, p = 0.000). Children with epilepsy and a HUI score of 1 scored 9.90 points lower (β = −9.902, 95%CI −16.343, −3.461, p = 0.003) while those with epilepsy and HUI < 1 scored 17.30 lower (β = −17.308, 95%CI −23.776, −10.839, p = 0.000).ConclusionThe data provide objective evidence that children with epilepsy are at risk of scholastic underachievement at school entry, while those with additional health impairments as measured by the HUI are at greater risk of underachievement.     

Predictors of disclosure management behavior at the end of 1-year follow-up in Korean adults with newly diagnosed epilepsy

PurposeEpilepsy is a concealable stigmatizing condition. We investigated the factors predicting disclosure management behavior in Korean adults with newly diagnosed epilepsy.MethodsThis longitudinal multicenter study included Korean adults with newly diagnosed epilepsy. Using statistical analyses, we determined at the end of a 1-year follow-up whether Disclosure Management Scale (DMS) scores were predicted by demographic, clinical, and psychosocial variables, including felt stigma, stress coping style, personality traits, social support, and experienced discrimination from society.ResultsOf a total of 121 participants, 69% reported that they often or sometimes kept their diagnosis a secret from others and rarely or never talked to others about their epilepsy. The average DMS score was 5.8 (SD = 2.9, range 0–11). In univariate analyses, DMS scores were significantly associated with an emotion-focused coping style (r = 0.320, p < 0.001), social support (r = − 0.185, p < 0.05), and experienced discrimination (p < 0.05). Emotion-focused coping was the only independent predictor of a higher DMS score. Felt stigma, personality traits, and seizure freedom were not related to the DMS score.ConclusionsTwo-thirds of Korean adults with newly diagnosed epilepsy often or sometimes keep their epilepsy a secret. Emotion-focused coping is the most important predictor of concealment of epilepsy diagnosis at the end of a 1-year follow-up, although social support and episodes of experienced discrimination are also associated with disclosure management strategies.     

Restless legs syndrome in end-stage renal disease: Clinical characteristics and associated comorbidities

BackgroundDespite being frequently described in patients with end-stage renal disease (ESRD), clinical characteristics and comorbidities in association with restless legs syndrome (RLS) are still to be confirmed.ObjectivesThe aim of this study was to investigate clinical factors associated with RLS in ESRD patients in hemodialysis.MethodsThis is a cross-sectional study of 400 patients on hemodialysis, evaluating RLS, clinical features and other sleep abnormalities.ResultsOut of 400, 86 patients presented RLS (21.5%; mean age 48.8 ± 13.8 y), being more frequent in females (p < 0.005). Forty-eight individuals (12% mean age 50.7 ± 13.1 y) had moderate/severe RLS, 14 reported symptoms prior to hemodialysis, 13 described family history of RLS, and eight described symptoms as disturbing during dialysis. RLS cases showed lower hemoglobin (p < 0.005), poorer quality of sleep (Pittsburgh Sleep Quality Index >5, p = 0.002), higher scores on the Beck Depression Inventory Scale (p < 0.005), greater scores on the Charlson Comorbidity Index (p = 0.01) and the Epworth Sleepiness Scale (p = 0.001) and higher risk of obstructive sleep apnea (OSA; Berlin questionnaire, p = 0.01). Hypertension was more frequent in cases with moderate/severe RLS (p = 0.01) and remained after controlling for the risk of OSA (p = 0.02).ConclusionIn ESRD patients in hemodialysis, RLS is present in 21.5%; 16% report symptoms prior to hemodialysis and a family history of RLS. Symptoms are disturbing during hemodialysis in 9% of cases. RLS is associated with lower hemoglobin, worse sleep quality, excessive daytime sleepiness, depressive symptoms and higher risk of OSA. Hypertension is associated with moderate/severe RLS.     

Attention deficits in children with epilepsy: Preliminary findings

ObjectiveAttention difficulties are a common clinical complaint among children with epilepsy. We aimed to compare a range of attentional abilities between groups of children with two common epilepsy syndromes, Temporal Lobe Epilepsy (TLE) and Idiopathic Generalized Epilepsy (IGE), and to healthy controls. We also investigated whether epilepsy factors (laterality of seizure focus, epilepsy onset, duration, and severity) were related to attentional abilities.MethodsMultiple dimensions of attention (selective, sustained, and divided attention and attentional control) were assessed directly with standardized neuropsychological measures in 101 children aged 6–16 years (23 children with TLE, 20 with IGE and 58 healthy controls). Attention was also assessed indirectly, via a parent-report measure.ResultsChildren with TLE performed worse than children with IGE (p = 0.013) and healthy controls (p < 0.001) on a test of attentional control, but no between-group differences were apparent on tests of other attentional abilities. Compared to healthy controls, greater attention problems were reported by parents of children with TLE (p = 0.006) and IGE (p = 0.012). Left-hemisphere seizure focus and greater epilepsy severity were associated with poorer attentional control and sustained-divided attention, respectively, but no other epilepsy factors were associated with attentional abilities.SignificanceThese findings suggest that children with localization-related epilepsy, but not generalized epilepsy, may be at risk of deficits in attentional control. Interventions aimed at improving attentional control may be targeted at children with localization-related epilepsy, particularly those with a left-hemisphere seizure focus, who appear to be particularly susceptible to this type of attentional deficit.     

A four year follow-up of sleep and respiratory measures in elementary school-aged children with sleep disordered breathing

ObjectiveLittle is known of the long-term prognosis of children treated for sleep disordered breathing (SDB) and even less of children with milder forms of SDB who remain untreated. We aimed to investigate the long-term sleep and respiratory outcomes of children with a range of SDB severities.Methods41 children with SDB and 20 non snoring controls (mean age, 12.9 ± 0.2 y), underwent repeat overnight polysomnography (PSG) 4.0 ± 0.3 years after initial diagnosis. SDB severity, presence of snoring, sleep and respiratory parameters, sleep fragmentation index (SFI), the Pediatric Daytime Sleepiness Scale (PDSS), Sleep Disturbance Scale for Children (SDSC), and obstructive sleep apnea 18-item quality of life questionnaire were re assessed. Children with SDB were grouped into resolved (no snoring and obstructive apnea–hypopnea index [OAHI] <1) and unresolved (snoring or an OAHI ⩾1).ResultsAt follow-up OAHI was reduced in both SDB groups (p < 0.05); however, 54% (n = 22) of children still continued to snore, having either persistent or new OSA (n = 4). In this unresolved group, sleep was significantly disrupted; % nonrapid eye movement stage 1 (NREM1) sleep and SFI were increased (p < 0.05), and total sleep time (TST) and sleep efficiency were decreased compared to the resolved and control groups (p < 0.05). Overall, 29% of children were treated, and of these, 67% had resolved SDB. SDB groups had higher PDSS, SDSC, and OSA-18 scores compared to controls at follow-up (p < 0.01).ConclusionsOur study demonstrated that although SDB improved in the long-term, more than 50% of children had residual SDB (mostly primary snoring) and sleep disturbance. As even mild forms of SDB are known to have adverse cardiovascular, learning, and behavioral outcomes, which have implications for the health of these children.     

Perceived epilepsy stigma mediates relationships between personality and social well-being in a diverse epilepsy population

IntroductionPerceived epilepsy stigma and reduced social well-being are prevalent sources of distress in people with epilepsy (PWE). Yet, research on patient-level correlates of these difficulties is lacking, especially among underserved groups.Materials and methodsRacially/ethnically diverse adults with intractable seizures (N = 60, 62% female; 79% Black, 20% Hispanic/Latino, 8% White) completed validated measures of personality (NEO Five Factor Inventory, NEO-FFI-3), perceived epilepsy stigma (Epilepsy Stigma Scale, ESS), and quality of life (Quality of Life Inventory in Epilepsy, QOLIE-89). Controlling for covariates, ordinary least-squares (OLS) regression evaluated the total, direct, and indirect effects of NEO-FFI-3 neuroticism and extraversion scores on epilepsy-related social well-being (i.e., combination of QOLIE-89 social isolation and work/driving/social function subscales, α = 0.87), mediated through perceived stigma.ResultsIn separate models, higher levels of neuroticism (N) and lower levels of extraversion (E) were significantly and independently associated with greater perceived stigma (N path a = 0.71, p = 0.005; E path a = − 1.10, p < 0.005). Stigma, in turn, was significantly and independently associated with poorer social well-being (N path b = 0.23, p < 0.001; E path b = − 0.23, p < 0.001). Bias-corrected bootstrap confidence intervals (CIs) showed that neuroticism and extraversion were indirectly associated with social well-being through their respective associations with perceived stigma (N path ab = − 0.16, 95% CIs [− 0.347, − 0.044]; E path ab = 0.25, 95% CIs [0.076, 0.493]).ConclusionHigher neuroticism and lower extraversion covaried with stigma beliefs, and these may be markers of poor social outcomes in PWE. Mediation models suggest that targeting epilepsy stigma beliefs may be a particularly useful component to incorporate when developing interventions aimed at promoting social well-being in diverse PWE.     

Association of social support and quality of life among people with schizophrenia receiving community psychiatric service: A cross-sectional study

ObjectiveTo understand the needs of patients with schizophrenia for recovery, this study examined the type and level of social support and its association with quality of life (QOL) among this group of patients in the city of Kuala Lumpur.MethodA cross-sectional study was conducted on 160 individuals with schizophrenia receiving community psychiatric services in Hospital Kuala Lumpur (HKL). The WHOQOL-BREF, Brief Psychiatric Rating Scale (BPRS) and Multidimensional Scale of Perceived Social Support (MSPSS) were used to assess QOL, severity of symptoms and social support, respectively. The study respondents were predominantly Malay, aged less than 40, males, single, unmarried, had lower education levels and unemployed.ResultsAbout 72% of the respondents had poor perceived social support, with support from significant others being the lowest, followed by friends and family. From multiple regression analysis, social support (total, friend and family) significantly predicted better QOL in all domains; [B = 0.315 (p < 0.001), B = 0.670 (p < 0.001), B = 0.257 (p < 0.031)] respectively in Physical Domain; [B = 0.491 (p < 0.001), B = 0.735 (p < 0.001), B = 0.631 (p < 0.001)] in Psychological Domain; [B = 1.065 (p < 0.001), B = 0.670 (p < 0.017), B = 2.076 (p < 0.001)] in Social Domain and; [B = 0.652 (p < 0.001), B = 1.199 (p < 0.001), B = 0.678 (p < 0.001)] in Environmental Domain. Being married and having shorter duration of illness, lower BPRS (total) scores, female gender and smoking, were also found to significantly predict higher QOL.ConclusionSocial support is an important missing component among people with schizophrenia who are already receiving formal psychiatric services in Malaysia.     

Predictors of intellectual functioning after epilepsy surgery in childhood: The role of socioeconomic status

ObjectiveThe objective of this study was to evaluate the association between socioeconomic status and intellectual functioning in children with medically refractory epilepsy, before and after resective epilepsy surgery. Family environment is a strong contributor to cognitive development in children and has been recently shown to play a significant role in intellectual outcome after surgery in children with epilepsy.MethodsOne hundred children who had undergone resective epilepsy surgery and completed preoperative and postoperative assessments of IQ as part of clinical care were included in the study. We evaluated the impact of epilepsy-related variables, income quintile, and residence location on IQ.ResultsGreater improvements in IQ after surgery were associated with an older age at surgery (β = .235, p = .018). Higher IQ scores at follow-up were associated with an older age of seizure onset (β = .371, p < .001), older age at surgery (β = .356, p < .001), unilobar epileptogenic focus (β = .394, p < .001), and mesial temporal sclerosis (β = .338, p = .001) or tumor (β = .457, p < .001) in comparison with malformation of cortical development; age at seizure onset did not remain as a significant predictor in multivariable regression analysis. Income quintile, residence location, seizure control, and antiepileptic medication use were not significant predictors.ConclusionsEpilepsy-related variables were the strongest predictors of IQ and postoperative change in IQ. We were unable to identify a significant association between IQ and socioeconomic status. Future research should evaluate the impact of multiple aspects of family environment.
