Classroom academic performance: improvement with both methylphenidate and dextroamphetamine in ADHD boys

Area of Science:

• Child Psychology
• Neuroscience
• Pharmacology

Background:

• Hyperactivity in children often impacts academic performance.
• Stimulant medications like dextroamphetamine and methylphenidate are commonly prescribed for attention disorders.
• Understanding the comparative effects of these stimulants on academic tasks is crucial.

Purpose of the Study:

• To compare the efficacy of dextroamphetamine (d-AMPH) and methylphenidate (MPH) on academic performance in hyperactive boys.
• To assess the impact of these stimulants on reading and math task completion and accuracy.
• To investigate potential dose-response relationships and adverse effects.

Main Methods:

• An 11-week double-blind, placebo-controlled, crossover study involving 33 hyperactive boys.
• Academic performance was measured using daily reading and math series tasks.
• Classroom performance metrics included tasks attempted and percent correct.

Main Results:

• Both d-AMPH and MPH increased the number of attempted reading and math tasks.
• Reading task accuracy improved with both d-AMPH and MPH.
• Math task accuracy improved only with d-AMPH.
• No significant dose-response relationship was observed for either stimulant.
• Moderate, transient adverse effects were reported for both medications.

Conclusions:

• Dextroamphetamine and methylphenidate can enhance academic task engagement and reading accuracy in hyperactive boys.
• Dextroamphetamine may offer a specific advantage in improving math accuracy.
• Both medications are generally well-tolerated with transient side effects.
• Further research is needed to explore long-term effects and individual responses.
