Cognition can be defined as gaining knowledge and comprehension, including thinking, knowing, remembering, judging and problem solving. Subject Several causal pathway models have been proposed, trying to combine the findings of biological and cognitive abnormalities frequently found in ADHD. The cognitive models all have in common that deficits in executive functioning EF are one of the most prominent characteristics of ADHD.
Adderall - Clinical Pharmacology Pharmacodynamics Amphetamines are non-catecholamine sympathomimetic amines with CNS stimulant activity.
Amphetamines are thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space. The PK parameters Cmax, AUC0-inf of d-and l-amphetamine increased approximately three-fold from 10 mg to 30 mg indicating dose-proportional pharmacokinetics.
Norephedrine and 4-hydroxy-amphetamine are both active and each is subsequently oxidized to form 4-hydroxy-norephedrine. Alpha-hydroxy-amphetamine undergoes deamination to form phenylacetone, which ultimately forms benzoic acid and its glucuronide and the glycine conjugate hippuric acid. Although the enzymes involved in amphetamine metabolism have not been clearly defined, CYP2D6 is known to be involved with formation of 4-hydroxy-amphetamine.
Since CYP2D6 is genetically polymorphic, population variations in amphetamine metabolism are a possibility.
Amphetamine is known to inhibit monoamine oxidase, whereas the ability of amphetamine and its metabolites to inhibit various P isozymes and other enzymes has not been adequately elucidated. However, due to the probability of auto-inhibition and the lack of information on the concentration of these metabolites relative to in vivo concentrations, no predications regarding the potential for amphetamine or its metabolites to inhibit the metabolism of other drugs by CYP isozymes in vivo can be made.
Since amphetamine has a pKa of 9. Alkaline urine pHs result in less ionization and reduced renal elimination, and acidic pHs and high flow rates result in increased renal elimination with clearances greater than glomerular filtration rates, indicating the involvement of active secretion.
Consequently, both hepatic and renal dysfunction have the potential to inhibit the elimination of amphetamine and result in prolonged exposures. The symptoms must cause clinically significant impairment, e. The symptoms must not be better accounted for by another mental disorder.
For the Inattentive Type, at least six of the following symptoms must have persisted for at least 6 months: For the Hyperactive-Impulsive Type, at least six of the following symptoms must have persisted for at least 6 months: The Combined Type requires both inattentive and hyperactive-impulsive criteria to be met.
Special Diagnostic Considerations Specific etiology of this syndrome is unknown, and there is no single diagnostic test.
Adequate diagnosis requires the use not only of medical but of special psychological, educational, and social resources. Learning may or may not be impaired.
Drug treatment may not be indicated for all children with this syndrome. Appropriate educational placement is essential and psychosocial intervention is often helpful. When remedial measures alone are insufficient, the decision to prescribe stimulant medication will depend upon the physician's assessment of the chronicity and severity of the child's symptoms.

One type of processing speed is visual processing speed, this is the most common kind referred to. Visual processing speed is how fast your child can look at and process information on a task that does not take any more thinking than noticing the differences or sameness in the objects shown.

Contraindications Advanced arteriosclerosis, symptomatic cardiovascular disease, moderate to severe hypertension, hyperthyroidism, known hypersensitivity or idiosyncrasy to the sympathomimetic amines, glaucoma.
Patients with a history of drug abuse. During or within 14 days following the administration of monoamine oxidase inhibitors hypertensive crises may result.We are gamers in our family.
But a fair number of unschooling parents of children with autism report the side effect of dysphoria after their children play video games or play them for too long. ADD/ADHD in Children: Information and Solutions ADD – ADHD or attention deficit/hyperactivity affects almost 10% of children in the USA or close to 5 million children and adolescents from three to eighteen years of age.
Jul 09, · The current review highlights the key features of the presentation of ADHD across development, explores predictors of its developmental course at different stages in life, and discusses some clinical implications of a developmental view of this disorder.
research has identified a variety of predictors of developmental course of. The impact of attention-deficit hyperactivity disorder (ADHD), or hyperkinetic disorder (HKD), on many areas of life is an important consideration, especially as ADHD affects not only the lives of the patients themselves, but also their families and carers.
1,2. Introduction. Attention Deficit Hyperactivity Disorder (ADHD) is characterized by a triad of symptoms of inattention, hyperactivity and impulsivity. 1 The disorder is highly heritable and affects around % of school-aged children.
2,3 In recent decades, the cognitive problems of ADHD have been widely studied. Cognition can be defined as gaining . Cognitive skills in children with autism vary and improve, study finds Date: September 16, Source: Society for Research in Child Development.
