Pharmacological and behavioral therapies have limited impact on the distinct neurocognitive impairments associated with ADHD, and existing cognitive training programs have shown limited efficacy. This proof-of-concept study assessed treatment acceptability and explored outcomes for a novel digital treatment targeting cognitive processes implicated in ADHD.
Participants included 40 children with ADHD and 40 children without ADHD. Following psychiatric screening, ADHD ratings, and baseline neuropsychological measures, participants completed 28-days of at-home treatment. Neuropsychological assessment was repeated at end-of-study along with treatment satisfaction measures.
Eighty-four percent of treatment sessions were completed and ratings showed strong intervention appeal. Significant improvements were observed on a computerized attention task for the ADHD group and a highly impaired ADHD High Severity subgroup. There was no change for the non-ADHD group. Spatial working memory also improved for the ADHD group and the ADHD High Severity subgroup.
Findings provide preliminary support that this treatment may improve attention, working memory, and inhibition in children with ADHD. Future research requires larger-scale randomized controlled trials that also evaluate treatment impact on functional impairments.

药物治疗和行为疗法对与注意力缺陷多动障碍(ADHD)相关的明显神经认知障碍影响有限,现有的认知训练项目疗效也有限。这项概念验证研究评估了一种针对ADHD所涉及认知过程的新型数字治疗的可接受性,并探索了其治疗效果。
参与者包括40名患有ADHD的儿童和40名未患ADHD的儿童。经过精神科筛查、ADHD评分和基线神经心理学测量后,参与者完成了为期28天的居家治疗。在研究结束时重复进行神经心理学评估以及治疗满意度测量。
84%的治疗疗程得以完成,评分显示出强烈的干预吸引力。ADHD组以及严重受损的ADHD高严重度亚组在一项计算机化注意力任务上有显著改善。非ADHD组则无变化。ADHD组以及ADHD高严重度亚组的空间工作记忆也有所改善。
研究结果提供了初步支持,表明这种治疗可能改善ADHD儿童的注意力、工作记忆和抑制能力。未来的研究需要进行更大规模的随机对照试验,同时评估治疗对功能障碍的影响。
