Summary
Attention-deficit/hyperactivity disorder (ADHD) affects 13% of Brazilian elementary students, a higher prevalence than previously reported. Boys were more commonly diagnosed with the combined subtype of ADHD.
Area of Science:
- Child and Adolescent Psychiatry
- Developmental Psychology
- Public Health
Context:
- Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder.
- Understanding ADHD prevalence in diverse populations is crucial for effective intervention strategies.
- Brazilian public elementary schools provide a key setting for identifying childhood behavioral and learning disorders.
Purpose:
- To determine the prevalence of attention-deficit/hyperactivity disorder (ADHD) among students in Brazilian public elementary schools.
- To analyze demographic patterns, including gender distribution and ADHD subtypes, within the studied population.
Summary:
- A prevalence study was conducted in four Brazilian public elementary schools involving students aged 6-12.
- Teachers initially screened students, followed by in-depth interviews and assessments for suspected cases.
- The study identified a 13% prevalence of ADHD, with a 2:1 male-to-female ratio and the combined subtype being most common.
Impact:
- The findings indicate a higher ADHD prevalence (13%) in this population compared to traditional estimates (3-5%).
- Results highlight the need for increased awareness and resources for ADHD diagnosis and management in Brazilian schools.
- The study confirms previous research on gender differences and subtype prevalence in ADHD.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
01:26Modeling in Therapy
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

01:08Prevalence and Incidence
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
