This study is aimed to investigate neuropsychological deficits in adult ADHD. Neuropsychological deficits in terms of executive functions, divided, selective, and sustained attention, were investigated in a group of adults with ADHD using a series of neuropsychological tests as well as electroencephalography (EEG). Subjective ratings of everyday life attention and memory problems were also collected. Adults with ADHD showed impairments in executive functions, divided attention and sustained attention, compared with adult controls. Performance on selective attention tasks in adults with ADHD was instead no different from control participants' performance. EEG results confirmed neuropsychological findings by showing a selective impairment on P3 event-related potential (ERP) amplitude indicative of sustained attention deficits. Higher subjective ratings of everyday attentional and memory problems were also found in the ADHD group compared with the control group. This pattern of results suggests differential impairments of attentional skills. Impaired executive functions and higher subjective functional impairments were also found.
本研究旨在探讨成人 ADHD 的神经心理学缺陷。使用一系列神经心理学测试和脑电图 (EEG)，对一组 ADHD 成人进行了执行功能、分散注意、选择性注意和持续注意等方面的神经心理学缺陷研究。还收集了日常生活中注意力和记忆力问题的主观评价。与成年对照组相比，ADHD 成人在执行功能、分散注意和持续注意方面存在缺陷。而 ADHD 成人在选择性注意任务上的表现与对照组参与者的表现没有差异。脑电图结果通过显示与持续注意力缺陷相关的 P3 事件相关电位 (ERP) 振幅的选择性损伤，证实了神经心理学发现。与对照组相比，ADHD 组也发现更高的日常注意力和记忆力问题的主观评分。这些结果表明注意力技能存在不同程度的损伤。还发现执行功能受损和更高的主观功能障碍。
