Background: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental pathology characterized by persistent degrees of inattention, and impulsivity - manifested in various spheres which the individual inserted associated with neural aspects prefrontal cortex. In this sense, directly affects learning development children.

Competing hypotheses for explaining the role of anxiety in the relation between attention-deficit/hyperactivity disorder (ADHD) symptoms and childhood aggression were evaluated. Two studies tested whether anxiety exacerbated, attenuated, or had no effect on the relation between ADHD and aggression subtypes among psychiatrically hospitalized children. In Study 1 (N = 99), children who scored abo...

British Journal of General Practice, April 2014 e243 Attention deficit hyperactivity disorder (ADHD) is characterised by inappropriate levels of inattention, hyperactivity, and impulsivity: the core symptoms. It is the most common neurobehavioural childhood disorder affecting 5% of children and 2–4% of adults worldwide.1 The National Institute of Health and Care Excellence (NICE)1 acknowledges ...

Although first identified in children in the 19th century, attention-deficit/hyperactivity disorder (ADHD) in adults was not described in the literature until 1976. The symptoms of adult ADHD resemble the symptoms of childhood ADHD, but symptom intensity, especially hyperactivity, may decrease over time. However, due to the challenges and responsibilities of adulthood, a normal day is extremely...

A mentally retarded 7-year-old male child presented with inattention and hyperactivity which was initially diagnosed as attention deficit hyperactivity disorder (ADHD). However, a careful evaluation of symptomatology along with clues provided by specific features of facial dysmorphism in this case along with genetic testing clinched the diagnosis of Smith-Magneis syndrome the behavioural phenot...

Abstract Injuries among children and young people are a leading cause of morbidity mortality in the UK globally. Attention-deficit/hyperactivity disorder (ADHD) is an important neurodevelopmental which can be present from preschool age but generally under-recognised. Children with ADHD at increased risk variety unintentional injuries. However, interventions to offer safety advice, asse...

Attention-Deficit/Hyperactivity Disorder A ttention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental (related to brain function) condition that is usually diagnosed in childhood. It can last into adulthood. Symptoms include difficulty staying focused or paying attention, excess motor activity (eg, fidgeting), and difficulty controlling impulsive behavior. Although most children hav...

We describe the first invertebrate model of attention deficit hyperactivity disorder (ADHD) that reproduces its major features, including hyperactivity, male predominance, marked exacerbation by simple carbohydrates, reversible response to dextroamphetamine, and a "paradoxical response" to stimulants. This model may offer new insight into ADHD pathogenesis and treatment. Furthermore, these find...

background attention deficit hyperactivity disorder (adhd) is a multi-factorial disorder that has defined by hyperactivity, impulsivity and attention deficits. various neurotransmitters such as dopamine can play a role in its pathophysiology. the aim of this study was to examine the association of two common single nucleotide polymorphisms in drd2 gene, taq i a (t/c) and taq i b (g/a), with adh...

the aim of this study was to determine melatonin effects on sleep patterns, symptoms of hyperactivity and attention deficiency in children with attention-deficit hyperactivity disorder (adhd).children with age range of 7-12 years who had a combined form of adhd were randomly divided in to 2 groups according to gender blocks. one group took melatonin (3 or 6mg) combined with methylphenidate (rit...
