objectives: tourette syndrome is a disorder with motor and vocal tics, which has many psychiatric comorbidities. attention deficit hyperactivity disorder (adhd) is one of co-morbid features of this syndrome. the aim of this research is studying tourette and co morbidity adhd in school age children. one of our purposes is to identify the range of adhd in iranian tourette patients. methods: thirt...

BACKGROUND Very preterm (VP) children are at particular risk for attention deficit/hyperactivity disorder (ADHD) of the inattentive subtype. It is unknown whether the neurodevelopmental pathways to academic underachievement are the same as in the general population. This study investigated whether middle childhood attention or hyperactivity/impulsivity problems are better predictors of VP adole...

A number of hypotheses have suggested that the principal neurological dysfunction responsible for the behavioural symptoms associated with Attention-Deficit/Hyperactive Disorder (ADHD) is likely rooted in abnormal phasic signals coded by the firing rate of midbrain dopamine neurons. We present a formal investigation of the impact atypical phasic dopamine signals have on behaviour by applying a ...

INTRODUCTION Idiopathic toe-walking (ITW) is described as a gait pattern with no contact between the heels and the ground in children older than 3years. The diagnosis is clinical, making it necessary to rule out other neurological and orthopaedic conditions. A relationship between ITW and vestibular dysfunction and/or proprioceptive sensibility has been proposed. Children with neurodevelopmenta...

PURPOSE This study aimed to explore the intelligence profiles of Chinese school-aged boys with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (ADHD). Additionally, differences in intelligence quotient (IQ) between the HFASD group and the ADHD group were examined. PATIENTS AND METHODS Thirty-two boys with HFASD, 58 boys with ADHD, and 39 typicall...

BACKGROUND Several recent behavioural and behavioural genetic studies have investigated the relationship between attention deficit hyperactivity disorder (ADHD) and mathematical ability. The aim of this systematic review was to provide an overview of these studies to date. An emphasis was placed on reviewing results that explored the association between mathematics and the two ADHD components o...

conclusions inattentive type and hyperactive-impulsive type of adhd are more prevalent in children with esrd undergoing capd. therefore screening methods for adhd is necessary in these patients. background attention-deficit/hyperactivity disorder (adhd) is the most common childhood psychiatric disorder. this disorder is more prevalent in some chronic disease. objectives the aim of this study wa...

Converging evidence suggests shared genetic underpinnings of attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Studies of infants at risk for ASD have proliferated over the past decade; the few studies that have followed these infants beyond age 3 report a range of difficulties facing a subset of these infants as they reach school age, including elevated levels...
