Attention-Deficit/Hyperactivity Disorder01:30

Attention-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.
Learning Disabilities01:25

Learning 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.

Adrenergic Agonists: Mixed-Action Agents01:28

Adrenergic Agonists: Mixed-Action Agents

Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
Adrenergic Agonists: Indirect-Acting Agents01:25

Adrenergic Agonists: Indirect-Acting Agents

Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

Area of Science:

  • Pediatric Psychiatry
  • Neurodevelopmental Disorders
  • Pharmacological Treatments

Background:

  • Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder in children.
  • Comorbid learning disabilities (LD) frequently occur in children with ADHD, complicating treatment.
  • Osmotic Release Oral System (OROS) methylphenidate is a long-acting formulation used for ADHD management.

Purpose of the Study:

  • To evaluate the efficacy of OROS methylphenidate in children with ADHD.
  • To compare treatment response in children with ADHD with and without comorbid learning disabilities (LD).

Main Methods:

  • Analysis of data from two 6-week, double-blind, randomized, placebo-controlled, crossover studies.
  • Inclusion of 135 children (ages 9-12) with ADHD, with or without LD (reading, math, or both).
  • Assessment using cognitive tests, academic tasks, and observed classroom behavior during OROS methylphenidate and placebo treatment phases.

Main Results:

  • OROS methylphenidate significantly improved ADHD Rating Scale scores in both ADHD with and without LD groups.
  • Participants showed enhanced performance on cognitive measures (e.g., Test of Variables of Attention) during OROS methylphenidate treatment.
  • Academic-related tasks and observed classroom behavior also improved with OROS methylphenidate compared to placebo.

Conclusions:

  • OROS methylphenidate treatment led to improvements in behavior and performance for children with ADHD.
  • The findings support the use of OROS methylphenidate in managing ADHD symptoms, even in the presence of comorbid learning disabilities.
