Predicting the response of hyperkinetic children to stimulant drugs: a review

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Pharmacology

Background:

• Hyperkinetic disorder, characterized by hyperactivity and impulsivity, affects a significant number of children.
• Stimulant medications are commonly prescribed, but predicting individual response remains a challenge.

Purpose of the Study:

• To review existing research and identify variables that predict favorable stimulant drug response in hyperkinetic children.
• To explore the heterogeneity of hyperkinetic children regarding central nervous system (CNS) arousal levels.

Main Methods:

• A comprehensive review of 36 research reports involving over 1,400 hyperkinetic children.
• Categorization of predictor variables into eight types: psychophysiological, neurological, familial, demographic/sociological, diagnostic, ratings, psychological, and profile types.

Main Results:

• Measures of attention span and concentration, along with their correlates, emerged as the most effective predictors of stimulant drug response.
• Evidence suggests that hyperkinetic children exhibit heterogeneity in CNS arousal levels, indicating its potential as a predictive variable.

Conclusions:

• Attention and concentration metrics are currently the strongest indicators for predicting stimulant efficacy in hyperkinetic children.
• Further investigation into CNS arousal could refine predictive models for stimulant drug response in this population.
