Summary
Cognitive tests can predict how well children and adolescents with ADHD respond to methylphenidate (MPH). Specific cognitive patterns identify responders and non-responders, aiding treatment planning.
Area of Science:
- Neuroscience
- Pediatric Psychiatry
- Cognitive Psychology
Background:
- Attention-Deficit/Hyperactivity Disorder (ADHD) is common in children and adolescents.
- Methylphenidate (MPH) is a frequently prescribed medication for ADHD.
- Predicting individual response to MPH is crucial for effective treatment.
Purpose of the Study:
- To evaluate the effectiveness of cognitive measures in predicting methylphenidate (MPH) response in pediatric ADHD.
- To identify specific cognitive profiles associated with MPH treatment outcomes.
Main Methods:
- Utilized data from the International Study to Predict Optimized Treatment-in ADHD (iSPOT-A).
- Administered a cognitive test battery to participants before MPH treatment.
- Employed Receiver Operator Characteristics (ROC) analysis to differentiate responders from non-responders based on ADHD symptom reduction.
Main Results:
- 62% of participants responded to MPH treatment.
- Non-responders exhibited deficits in attention switching, sustained attention, planning, and impulsivity.
- Two responder subgroups were identified: one with impaired attention switching/impulsivity (older age) and another with enhanced attention switching and strong CPT/digit span scores.
Conclusions:
- Cognitive testing offers a practical and cost-effective method for tailoring ADHD treatment.
- Identifying cognitive markers can optimize methylphenidate (MPH) prescribing for children and adolescents.
- This approach supports personalized medicine in pediatric ADHD management.

1.4K
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.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
911
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.

01:30Information Processing Approach
882
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...

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...
