Objectives: There is a need to examine the utility of objective measures of attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Objective measures of ADHD symptoms, such as physical activity, may provide a more nuanced assessment of behavior that can be used to augment traditional cross-informant ratings of ADHD symptoms by…

Background: Attention deficit hyperactive disorder (ADHD) is a leading mental disorder among adolescents globally and is associated with premature mortality. Knowing the trends and key determinants of ADHD in youth are critical for earlier diagnosis and interventions. Methods: We retrospectively examined all hospitalizations in patients aged 11 to…

With the research reported on here we sought to determine whether children with attention-deficit/hyperactivity disorder (ADHD) displayed more symptoms of oppositional defiant disorder (ODD), conduct disorder (CD) and anger, which are categorised as externalising disorders, when contrasted to the control group and, also, whether gender and age…

The prevalence of autism spectrum disorder in South Africa is unknown and, to date, very little research has been performed within school systems that could inform the rates, distribution and profile of needs of children with autism spectrum disorder in education. We performed a comprehensive database search of all children with autism spectrum…

This study extends a body of research indicating a relationship between negative emotion and Attention Deficit-Hyperactivity Disorder (ADHD). Gender differences in the self-reporting of negative emotion among college students with ADHD were examined. Sixty-four college students (39 male, 25 female), with a diagnosis of ADHD, and 109 college…

Children with intellectual and developmental disabilities are at heightened risk for mental disorders. Using current diagnostic criteria, disruptive behavior disorders, specifically Attention-Deficit/Hyperactivity Disorder (ADHD), appear to be the most prevalent co-occurring disorders. However, the validity of ADHD as a diagnosis for children and…

Objective: Unresolved questions exist concerning diagnosis of ADHD. First, some studies suggest a potential overdiagnosis. Second, compared with the male-female ratio in the general population (3:1), many more boys receive ADHD treatment compared with girls (6-9:1). We hypothesized that this occurs because therapists do not adhere to "Diagnostic…

Students with attention-deficit/hyperactivity disorder (ADHD) exhibit chronic behavior difficulties that deleteriously impact their academic and social functioning in school settings. These difficulties not only impair student performance, but also present significant challenges to teachers, school psychologists, and other school professionals…

Objective: To investigate a potential relationship between coincidental increases in perinatal Pitocin usage and subsequent childhood ADHD onset in an attempt to isolate a specific risk factor as an early biomarker of this neurodevelopmental disorder. Method: Maternal labor/delivery and corresponding childbirth records of 172 regionally diverse,…

Poor handwriting has been shown to be associated with developmental disorders such as Developmental Coordination Disorder, Attention Deficit Hyperactivity Disorder, autism, and learning disorders. Handwriting difficulties could lead to academic underachievement and poor self-esteem. Therapeutic intervention has been shown to be effective in…

Background: Guidelines for assessment, diagnosis, and treatment of ADHD have been drawn from research focused primarily on Caucasian males generating, in part, the need to redress health disparities. Diagnostic criteria may therefore be limited, especially regarding gender differences and other associated cultural, familial, socio-environmental,…

For clinically referred children with Autism Spectrum Disorder (ASD) or Attention Deficit/Hyperactivity Disorder (ADHD) several early indicators have been described. However, knowledge is lacking on early markers of less severe variants of ASD and ADHD from the general population. The aim of the present study is to identify early indicators of…

This study investigated the readiness for self-directed learning of adults with Attention Deficit Hyperactivity Disorder (ADHD), as well as their overall educational experiences. Using Guglielmino's Self-Directed Learning Readiness Scale for Adults (SDLRS-A), the researcher investigated whether the following factors were significantly related to…

Background: The underlying mechanism of time perception deficit in long time intervals in attention-deficit/hyperactivity disorder (ADHD) is still unclear. This study used the time reproduction dual task to explore the role of the attentional resource in time perception deficits among children and adolescents with ADHD. Methods: Participants…

Like many childhood disorders, prevalence rates of AD/HD differ significantly across gender, with male-to-female ratios ranging from 2:1 to 9:1 depending on the sample (APA, 1994). Limited research has been conducted thus far in an effort to better understand these differential prevalence rates. However, it has been proposed that the current…
