- Personality Characteristics of Children and Adolescents with Anxiety Disorder from a Maternal Perspective: A Brief Report(2023) SANTOS, Erica da Cruz; LOPES, Maria-Cecilia; ASBAHR, Fernando Ramos; RODRIGUES, Camila Luisi; SAFFI, Fabiana; SPRUYT, Karen; SERAFIM, Antonio de Padua; ROCCA, Cristiana Castanho de AlmeidaThe present study assessed the personality characteristics of children and adolescents with anxiety disorder from a maternal perspective. A total of 48 children and adolescents aged between 8 and 17 years participated in this study, which was organized as follows: a clinical group (24 children and adolescents with anxiety disorders and their respective mothers) and a control group (24 children and adolescents without psychiatric diagnosis and their mothers). The participants were submitted to the WASI, CBCL, MASC-2, and EPQ-J tests and their mothers to the SRQ-20 and PIC-2 tests. The results showed higher rates of internalizing symptoms in the clinical group. In addition, patients showed less interest in hobbies, less adherence to social organizations, impairment in social activities, and commitment to school performance compared to the control group. There was a positive correlation between the mothers' symptoms and each of the following PIC-2 domains: somatic concern (p < 0.01) and psychological discomfort (p < 0.01). In conclusion, youths with AD showed a withdrawn and reserved personality profile, involving distrust of impulses and avoidance of interactions with peers. Furthermore, psychoemotional problems of mothers adversely influenced the perception followed by anxiety and adjustment characteristics. More studies are needed to assess the maternal personality in youths with anxiety.
- Attention deficit hyperactivity disorder and restless leg syndrome across the lifespan: A systematic review and meta-analysis(2023) MIGUEIS, D. P.; LOPES, M. C.; CASELLA, E.; SOARES, P. V.; SOSTER, L.; SPRUYT, K.This systematic review aims to assess the association between attention deficit hyperactivity disorder (ADHD) and restless legs syndrome (RLS) in accordance with the Preferred Reporting Items for Sys-tematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases were searched for original articles that reported prevalence data on ADHD and RLS until January 24th, 2023. Two independent reviewers evaluated the quality of the articles using the National Institutes of Health assessment tool. Among the 208 articles identified between 1996 and 2022, 29 were included. In large general population studies, 2.6-15.3% of participants met the RLS criteria, of which 3.2-17.4% presented with ADHD. In the ADHD group, RLS symptoms ranged from 11 to 42.9% in children and 20-33.0% in adults. This suggests a strong co-occurrence between RLS and ADHD. A common characteristic of these conditions is sleep fragmen-tation, as discussed in the reviewed papers. Although large-scale studies with comparable diagnostic criteria across the lifespan are required, our findings may advocate a possible common physiological pathway, including sleep fragmentation and dopaminergic system impairment.(c) 2023 Elsevier Ltd.

- Sleep and Daytime Complaints During Manic and Depressive Episodes in Children and Adolescents With Bipolar Disorder(2020) LOPES, Maria Cecilia; BOARATI, Miguel Angelo; FU-I, LeeIntroduction Depressive and manic episodes of bipolar disorder can interact with sleep complaints, followed by a worsened psychiatric condition. The aim of this study was to examine the interaction of sleep disorders with bipolar disorder in youths during depressive and manic episodes. Methods The target population was children and adolescents drawn from the Children and Adolescents Affective Disorder Program. Clinical assessment for current psychiatric diagnosis was done by direct clinical interview, Diagnostic Interview for Children and Adolescents (DSM-IV), and best-estimated clinical consensus. We applied sleep questionnaires from which we obtained sleep and daytime complaints during manic and depressive episodes. All statistical tests of significance were done using 2-tailed tests with alpha = 0.05. Results Participants in this study comprised 29 children (age = 10 +/- 3 years, boys = 23) and 43 adolescents (age = 15 +/- 2.4 years, boys = 30). Sleep complaints were observed in 66.4% of participants during manic episodes and 52.3% during depressive episodes. 37.9% of patients had sleep complaints in both episodes. Time in bed was longer during depressive episodes than manic episodes (p = 0.01). We found a high prevalence of nocturnal enuresis in depressive episodes in children and adolescents, which was statistically significant compared with manic episodes (p < 0.05). Unrested sleep was higher in adolescents in both episodes, and it was statistically significant during manic episodes (p < 0.05). Conclusion According to our analyses, the minority of patients had sleep complaints in both episodes. Our data showed that nocturnal enuresis occurred more frequently during depressive than manic episodes. Further research is necessary to understand the implications of these data.
- Cardiac autonomic control during non-REM and REM sleep stages in paediatric patients with Prader-Willi syndrome(2021) BRITO, Leandro C.; QUEIROGA, Thereza; FRANCO, Ruth R.; PASSONE, Caroline G. B.; LOPES, Maria-Cecilia; SHEA, Steven A.; BUENO, Clarissa; SOSTER, Leticia M. S. F. A.Cardiac death is the second most prevalent cause in Prader-Willi syndrome (PWS). Paediatric patients with PWS often present cardiac autonomic dysfunction during wakefulness, obesity and sleep-disordered breathing. However, the extent of cardiac autonomic modulation during sleep in PWS has not been documented. The objective of this study was to assess alterations in cardiac autonomic modulation of paediatric patients with PWS during different sleep stages. Thirty-nine participants in three groups: 14 PWS, 13 sex and age-matched lean controls (LG) and 12 obese-matched controls (OB). All participants underwent overnight polysomnography, including continuous electrocardiogram recordings. Heart rate variability (HRV) was analysed during representative periods of each sleep stage through time and frequency domains calculated across 5-min periods. Between-within ANOVAs were employed (p < .05). The results show that total HRV was lower in PWS than OB and LG during slow-wave sleep (SWS) (standard deviation of all NN intervals [SDNN] ms,p = .006). Parasympathetic modulation assessed by time-domain analysis was lower during SWS in PWS compared to both OB and LG (square root of the mean of the sum of the squares of differences between adjacent NN intervals [RMSSD] ms,p = .004; SDSD, standard deviation of differences between adjacent NN intervals [SDSD] ms,p = .02; number of adjacent NN intervals differing by >50 ms [NN50] ms,p = .03; proportion of adjacent NN intervals differing by >50 ms [pNN50] ms,p = .01). Sympathovagal balance assessed by frequency-domain analysis was lower during both N2 and SWS than during the rapid eye movement (REM) sleep stage, but not different among groups. In conclusion, this group of paediatric patients with PWS had impaired cardiac autonomic balance due to reduced parasympathetic modulation during SWS. This result could imply an underlying increased cardiovascular risk in PWS even during early age and independent of obesity.
conferenceObject NORMATIVE DATA OF CYCLIC ALTERNATING PATTERN ACROSS THE LIFESPAN(2022) MIGUEIS, Debora; LOPES, Maria-Cecilia; SPRUYT, Karen; LACERDA, Glenda- A systematic review and meta-analysis of the cyclic alternating pattern across the lifespan(2021) MIGUEIS, D. P.; LOPES, M. C.; IGNACIO, P. S. D.; THULER, L. C. S.; ARAUJO-MELO, M. H.; SPRUYT, K.; LACERDA, G. C. B.Background: Cyclic alternating pattern (CAP) is the electroencephalogram (EEG) pattern described as a marker of sleep instability and assessed by NREM transient episodes in sleep EEG. It has been associated with brain maturation. The aim of this review was to evaluate the normative data of CAP parameters according to the aging process in healthy subjects through a systematic review and meta-analysis. Methods: Two authors independently searched databases using PRISMA guidelines. Discrepancies were reconciled by a third reviewer. Subgroup analysis and tests for heterogeneity were conducted. Results: Of 286 studies, 10 submitted a total of 168 healthy individuals to CAP analysis. Scoring of CAP can begin at 3 months of life, when K-complexes, delta bursts, or spindles can be recognized. Rate of CAP increased with age, mainly during the first 2 years of life, then decreased in adolescence, and increased in the elderly. The A1 CAP subtype and CAP rate were high in school-aged children during slow-wave sleep (SWS). A1 CAP subtypes were significantly more numerous in adolescents compared with other groups, while the elderly showed the highest amounts of A2 and A3 CAP subtypes. Our meta-analysis registered the lowest CAP rate in infants younger than 2 years old and the highest in the elderly. Conclusions: This review summarized the normative data of CAP in NREM sleep during the aging process. The CAP rate increased with age and sleep depth, especially during SWS. Parameters of CAP may reflect gender hormonal effects and neuroplasticity. More reports on CAP subtypes are needed for their reference values establishment.
- Reduction in Parasympathetic Tone During Sleep in Children With Habitual Snoring(2019) LOPES, Maria-Cecilia; SPRUYT, Karen; AZEVEDO-SOSTER, Leticia; ROSA, Agostinho; GUILLEMINAULT, ChristianIntroduction: Changes in the autonomic nervous system due to Obstructive Sleep Apnea (OSA) during the life span have been described. Some pediatric studies have shown cardiovascular effects in children who do not fit the criteria for OSA; namely children with mild sleep disordered breathing. Objective: We investigated heart rate variability (HRV) during sleep in children with chronic snoring and flow limitation events during sleep. Methods: Ten children and adolescents with chronic snoring and an apnea hypopnea index < 1, associated to high Respiratory Index, and 10 controls matched for age, gender, and Tanner stage were monitored following one night of habituation in the sleep laboratory. HRV was studied at each sleep stage. The time and frequency domains were calculated for each 5-min period. Results: All patients were chronic heavy snorers. They presented an apnea hypopnea index = 0.8, respiratory disturbance index = 10.2/h with lowest O2 saturation 96.1 +/- 2.4%. The total power of HRV was decreased in all stages (p < 0.05). There was also a decrease in NN50 and pNN50 during all sleep stages compared to healthy controls (p = 0.0003 and p = 0.03, respectively). Conclusion: A reduction in parasympathetic tone was found in the patient group. This may represent an autonomic impairment during sleep in children with mild SDB. A reduction in HRV in children with habitual snoring could be associated with possible increases in cardiovascular risk in adulthood. Significance: The study indicates that children with habitual snoring have important parasympathetic tone changes during sleep.
