Barriers to early identification of autism in Brazil

Objective: Parents of children with autism spectrum disorders (ASD) seem to perceive that their child's development is not following the normal pattern as early as the first year of life. However, ASD children may not receive a diagnosis until they are of preschool age, especially in low- and middle-income countries. The objective of this study was to evaluate the pathway between initial parental concerns about atypical child development and ASD diagnosis in Brazil. Methods: Nineteen mothers whose children had been diagnosed with ASD participated and were interviewed. The ASD group consisted of two girls and 17 boys, with a mean age of 93.0 months (SD 48.4 monthsrange 39-197 months). Results: Mothers had their first concerns regarding ASD when children were 23.6 +/- 11.6 months old, but formal diagnosis occurred at a mean +/- SD age of 59.6 +/- 40.5 months, corresponding to a 3-year delay. Most mothers felt discouraged to address their concerns due to negative experiences with health professionals. Conclusion: In Brazil, mothers perceived the first signs of ASD in their children at an age similar to that reported in other countries, but the diagnosis of ASD seemed to be delayed. Consistent with the literature, mothers reported negative experiences with health professionals during the pathway to achieving ASD diagnosis.Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Univ Fed Sao Paulo UNIFESP, Dept Psiquiatria, Ambulatorio Cognicao Social Marcos Tomanik Mercad, Sao Paulo, SP, BrazilUniv Presbiteriana Mackenzie, Programa Posgrad Disturbios Desenvolvimento, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Ambulatorio Cognicao Social Marcos Tomanik Mercad, Sao Paulo, SP, BrazilWeb of Scienc

Lifetime psychopathology among the offspring of Bipolar I parents

BACKGROUND: Recent studies have demonstrated high rates of psychopathology in the offspring of parents with bipolar disorder. The aim of this study was to identify psychiatric diagnoses in a sample of children of bipolar parents. METHOD: This case series comprised 35 children and adolescents aged 6 to 17 years, with a mean age of 12.5 + 2.9 years (20 males and 15 females), who had at least one parent with bipolar disorder type I. The subjects were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime version (K-SADS-PL). Family psychiatric history and demographics were also evaluated. RESULTS: Of the offspring studied, 71.4% had a lifetime diagnosis of at least one psychiatric disorder (28.6% with a mood disorder, 40% with a disruptive behavior disorder and 20% with an anxiety disorder). Pure mood disorders (11.4%) occurred less frequently than mood disorders comorbid with attention deficit hyperactivity disorder (17.1%). Psychopathology was commonly reported in second-degree relatives of the offspring of parents with bipolar disorder (71.4%). CONCLUSIONS: Our results support previous findings of an increased risk for developing psychopathology, predominantly mood and disruptive disorders, in the offspring of bipolar individuals. Prospective studies with larger samples are needed to confirm and expand these results.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)NARSADKrus Endowed Chair in Psychiatry UTHSCSAFederal University of São Paulo Department of PsychiatryThe University of Texas Health Science Center Departments of Psychiatry and OrthodonticsUniversidade de São Paulo Faculdade de Medicina Department of PsychiatryUniversity of Texas Health Science CenterThe University of Texas Health Science Center Department of PsychiatryUNIFESP, Department of PsychiatryNARSAD: MH 69774NARSAD: RR 20571NARSAD: MH068280SciEL

Pre-verbal and verbal pattern as predictors for the implementation of the Picture Exchange Communication System (PECS) in autistic children

ABSTRACT Purpose: to investigate the preverbal and verbal patterns in autism spectrum disorder, to more easily predict the need for implementation of the Picture Exchange Communication System in autistic children who are about to start speech language therapy. Methods: a cross-sectional study with a sample consisted of 62 children aged 2 to 10 years, presented with autism spectrum disorder. The Vocal Behavior Assessment which analyzes the preverbal and verbal patterns through three parameters, that is, Mean Extension (mean verbal emission), Speech Characterization (number of atypical emissions) and Language Range (typical emissions of child development), was used. Sociodemographic data, intellectual quotient and non-adaptive behaviors were also analyzed, by using the logistic regression model. Results: there was a high sensitivity (0.915) and specificity (0.867) for the variables Speech Characterization (p=0,000) and Mean Extension (p=0,001). The other numerical variables, such as age, time of schooling, non-adaptive behaviors and intellectual quotient of children were tested but were not identified as potential predictors for the outcome of interest of the study. Conclusion: the indices of Speech Characterization and Mean Extension were identified as predictors for the indication of the Picture Exchange Communication System in children who are about to start speech language therapy

Profile of Service Use and Barriers to Access to Care among Brazilian Children and Adolescents with Autism Spectrum Disorders

Delayed diagnosis and a lack of adequate care for people with autism spectrum disorder (ASD) are related to worse outcomes and quality of life. This study aimed to identify the profile of service use, barriers to access care, and factors related to those barriers in Brazilian families with children with ASD. A total of 927 families with children with ASD (3-17 years) from five Brazilian regions completed an online version of the Caregivers Needs Survey. Results showed that the most used services were behavioral interventions and pharmacotherapy, while the most used professionals were neurologists, nutritionists, speech therapists, psychiatrists, psychologists, and pediatricians. The main barriers included waiting lists, costs, and the absence of services or treatment. Service use varied according to age, the region of residence, type of health care system used, and the parents/caregivers\u27 education. Access to behavioral interventions was more frequent among users of the private system/health insurance and families whose caregivers had higher education. The absence of specialized services/treatments was less frequent among residents of state capitals and families whose caregivers had higher levels of education. This study highlights how families with children/adolescents with ASD in Brazil face significant barriers to access care related to sociodemographic factors

Morphology of the subgenual prefrontal cortex in pediatric bipolar disorder

The subgenual prefrontal cortex (SGPFC) is an important brain region involved in emotional regulation and reward mechanisms. Volumetric abnormalities in this region have been identified in adults with bipolar disorder but thus far not in pediatric cases. We examined the volume of this brain region in subjects with pediatric bipolar disorder (PBD) and compared them to healthy controls

Validation of a Tool to Evaluate Drug Prevention Programs Among Students

Background: School-based prevention programs have been implemented worldwide with the intention of reducing or delaying the onset of alcohol and drug use among adolescents. However, their effects need to be evaluated, being essential to use validated and reliable questionnaires for this purpose. This study aimed to verify the semantic validity and reliability of an instrument developed to evaluate the results of a government drug prevention program for schoolchildren called #Tamojunto2.0.Methods: This is a mixed methods study with quantitative (test-retest, confirmatory factor analysis and non-response evaluation) and qualitative analyses (focus group and field cards). The self-administered questionnaires were used for a sample of 262 eighth-grade students (elementary school II) in 11 classes of four public schools in the city of São Paulo.Results: The level of agreement was substantial (Kappa 0.60–0.79) or almost perfect (Kappa > 0.8) for almost all questions about the use of marijuana, alcohol, cigarettes, cocaine, crack, and binge drinking. The model fit indices, for almost all secondary outcomes, indicated that the modls underlying each scale, constituted by observed and latent variables, had a good fit adjustument. The focus groups and field cards provided high-quality information that helped the researchers identify the main difficulties in applying and understanding the questions.Conclusion: The questionnaire showed high factorial validity, reliability and understanding by adolescents. After the necessary changes, identified in this study, the questionnaire will be suitable to evaluate the results of the #Tamojunto2.0 program in a randomized controlled trial

Prefrontal gray matter increases in healthy individuals after lithium treatment: A voxel-based morphometry study

The objective of this study was to test the hypothesis that 4 weeks of lithium administration would be associated with changes in brain gray and white matter volumes in healthy individuals. Thirteen right-handed healthy volunteers (6 females, mean age = 25.9 ± 10.0 y) were studied. 3D SPGR MRIs (TR = 25ms, TE = 5ms, slice-thickness = 1.5mm) were acquired using a 1.5 T GE Signa Imaging System, at baseline and after 4 weeks of lithium administration at therapeutically relevant doses. Optimized voxel based morphometry (VBM) analyses were conducted. Left and right dorsolateral prefrontal cortex and left anterior cingulate gray matter volumes increased significantly following lithium administration. Total white matter volume was increased, whereas total brain volume and total gray matter volume were not significantly changed following 4 weeks of lithium. Lithium treatment resulted in prefrontal regional gray matter volume increases in healthy volunteers, as well as increases in total white matter volume. Whether these changes are mediated by neurotrophic/neuroprotective or osmotic effects remains unknown
