Key Takeaway
Consider cognitive training programs may improve executive functions in preschoolers with ADHD, but evidence remains preliminary.

A randomized controlled trial evaluated two cognitive training interventions in 47 preschool children with ADHD. Participants were assigned to either the Attentive Rehabilitation of Attention and Memory (ARAM) program (N=15), the Program for Executive Function Training (PETRA) (N=15), or a control group (N=17). The study assessed behavioral outcomes using BRIEF and ADHD-SC4 scales and cognitive outcomes including the Day/Night Stroop, Missing Scan Test, and Trail Making Test.

Both interventions demonstrated improvements in multiple domains including inhibitory control, shifting attention, memory, planning, and emotion regulation, along with sustained reductions in ADHD symptoms. The analysis used Cohen's d to evaluate transfer effects across FIELD domains (Function, Implement, Ecology, Level, Duration), with PETRA generally showing larger effect sizes across these domains. However, specific numerical results for clinical outcomes, absolute numbers, p-values, and confidence intervals were not reported in the abstract.

Safety and tolerability data were not reported, and the abstract does not include information about adverse events, serious adverse events, or discontinuations. The study limitations were not detailed in the abstract. While the RCT design suggests causal inference is possible for the interventions studied, the lack of specific clinical outcome measures and safety data limits definitive conclusions. These findings represent preliminary evidence that requires confirmation through full publication with complete methodology and results reporting.

Researchers conducted a small study to see if two different cognitive training programs could help preschoolers with ADHD. The study involved 47 children who were randomly assigned to either the ARAM program, the PETRA program, or a control group that did not receive the training. The goal was to see if these programs could improve thinking skills and behavior.

Both training programs showed improvements in areas like paying attention, controlling impulses, remembering things, and managing emotions. The children also showed sustained reductions in their ADHD symptoms. The PETRA program generally showed slightly larger positive effects across different areas of daily life compared to the ARAM program.

It's important to be cautious about these results. The study was small, and the researchers did not report specific numbers for how much symptoms improved. They also did not report any information about safety or side effects from the training. The abstract does not mention the study's limitations.

For now, this research suggests that structured cognitive training might be a helpful approach for young children with ADHD. However, parents and doctors should view this as promising early evidence, not as proof that these specific programs work. More research with more children and longer follow-up is needed.

What this means for you:
Early, small study finds cognitive training may help preschoolers with ADHD, but more research is needed.

This study evaluates the effectiveness of two cognitive training interventions-Attentive Rehabilitation of Attention and Memory (ARAM) and the Program for Executive Function Training (PETRA)- in improving behavioral symptoms and cognitive functions in preschoolers with ADHD. 47 preschool children with ADHD were randomly assigned to either the ARAM (N = 15), PETRA (N = 15), or control group (N = 17). Behavioral outcomes were assessed using the Behavior Rating Inventory of Executive Function (BRIEF) and ADHD Symptom Checklist (ADHD-SC4) and cognitive outcomes were measured by Day/Night Stroop, Missing Scan Test, and Trail Making Test. Statistical analysis was conducted using mixed-design ANOVA for group × time comparisons, and transfer effects were evaluated using effect sizes (Cohen's d) within different FIELD domains (Function, Implement, Ecology, Level, and Duration). Both ARAM and PETRA demonstrated improvements in inhibitory control, shifting attention, memory, planning, and emotion regulation, with sustained reductions in ADHD symptoms. Analysis of transfer effects indicated that both ARAM and PETRA promoted transferability across the FIELD domains, with PETRA generally showing larger effect sizes across function, implement, ecology, level, and duration.
