Summary
Methylphenidate (MPH) treatment significantly improved executive functions like inhibition, memory, and planning in children with attention deficit hyperactivity disorder (ADHD). Most improvements reached typical levels, except for inhibition.
Area of Science:
- Neuroscience
- Child Psychology
- Pharmacology
Context:
- Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder impacting executive functions.
- Executive functions (EF) are crucial for goal-directed behavior and academic success.
- Methylphenidate (MPH) is a common stimulant medication used to manage ADHD symptoms.
Purpose:
- To investigate the efficacy of methylphenidate (MPH) in enhancing executive functions (EF) in children diagnosed with ADHD.
- To quantify the degree of improvement in specific EF domains following MPH treatment.
Summary:
- An open-label study evaluated 29 children with ADHD before and after treatment with OROS methylphenidate (MPH).
- Performance on tasks assessing inhibition, visual working memory, set-shifting, and planning showed significant improvements post-treatment.
- Compared to typically developing peers, ADHD children on MPH demonstrated improvements, reaching near-normal levels in most EF aspects, with inhibition being a notable exception.
Impact:
- Methylphenidate (MPH) demonstrates a positive impact on multiple executive functions in children with ADHD.
- Treatment with MPH can help ADHD children's executive function performance approach that of their neurotypical peers.
- Findings suggest MPH is effective in remediating specific cognitive deficits associated with ADHD, potentially improving daily functioning and academic outcomes.

01:30Attention-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.

01:30Information Processing Approach
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
01:30Cognitive 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...
01:28Adrenergic 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...

01:24CNS 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...
