Associated Factors of Attention-Deficit/Hyperactivity Disorder Diagnosis and Psychostimulant Use: A Nationwide Representative Study.

Background: Connections between epidemiological findings and children's and adolescents' mental health policies have not been properly made in Brazil, and such nationwide studies are scarce. This epidemiological study (1) estimated the prevalence and predictors of parent-reported attention-deficit/hyperactivity disorder (ADHD) (ADHD-report), (2) estimated the probable diagnosis and risk of ADHD based on Diagnostic and Statistical Manual of Mental Disorders, 5th edition, criteria (ADHD-probable), and (3) estimated current psychostimulant use (ADHD-pst) in a representative nationwide sample of Brazilian school-aged children and adolescents.

Methods: Data were obtained from 7114 school-aged children (49.

Resilience and vulnerability in adolescents with primary headaches: A cross-sectional population-based study.

Background: A scarcity of studies on the role of resilience resources (RRs) and vulnerability risk (VR) in children and adolescents with primary headache hampers the development of a risk-resilience model for pediatric headaches.

Objective: To examine the extent to which headache frequency and diagnosis are associated with RRs and VR and explore possible predictors of low RRs and high VR in a cross-sectional population-based study in adolescents.

Methods: This is a cross-sectional population study conducted in a small city in Brazil (Delfinópolis).

Psychometric properties and clinical utility of the executive function inventory for children and adolescents: a large multistage populational study including children with ADHD.

Executive functions (EF) are a set of high order mental abilities that regulate cognition, emotions, and behavior. This study aims to report the construction and validation of a rating scale instrument for EF in children and adolescents aged from 5 to 18 years (EFICA), as well as to report the results of a comparison between children with ADHD and their peers without it. Thus, we conducted a population-based cross-sectional study relying on a sample composed of 3,284 typical children and adolescents accessed to study the psychometric properties of the parents' inventory (EFICA-P) and the teacher's inventory (EFICA-T) within a Structural Equation Modeling framework (SEM).

Painful Temporomandibular Disorder Is Associated With Migraine in Adolescents: A Case-Control Study.

Some types of primary headaches and temporomandibular disorders (TMD) are comorbid in adults and highly prevalent in adolescents. Herein, we investigated the association of painful TMD with specific headache diagnoses (migraine, tension-type headache) and with headache frequency in adolescents. We also explored the association of headache diagnosis with the number of painful sites in the trigeminal area.

Recent advances in the management of chronic migraine in children.

Migraine is a chronic-recurrent disorder that progresses in some adults and also in many children. Chronic migraine (CM) is the clinical result of this process. Since migraine does not progress in most children, identifying the risk factors for progression is an important public health priority that should be matched by evidence-based treatment.

ADHD Is Comorbid to Migraine in Childhood: A Population-Based Study.

Recurrent headaches and ADHD are prevalent in the pediatric population. Herein, we assess if ADHD is comorbid to headaches overall, to headache subtypes (e.g.

Prenatal exposure to tobacco and alcohol are associated with chronic daily headaches at childhood: A population-based study.

The influence of prenatal events on the development of headaches at childhood has not been investigated and is the scope of our study. Of 2,173 children identified as the target sample, consents and analyzable data were provided by 1,440 (77%). Parents responded to a standardized questionnaire with a validated headache module and specific questions about prenatal exposures.

An epidemiologic study of headaches in Brazilian schoolchildren with a focus on pain frequency.

The purpose of this study was to assess the prevalence and frequency of the headaches in Brazilian schoolchildren. A cross-sectional study was conducted between March and November 2004 in São José do Rio Preto, São Paulo State, Brazil. A sample of 5,232 children from elementary schools was selected using proportional stratified sampling method.
