ABSTRACT

This study examined the neuropsychological profile of patients with Attention-Deficit/Hyperactivity Disorder (ADHD) based on Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) working memory and processing speed indices. We aimed to establish whether distinct ADHD subtypes emerge based on neuropsychological testing and determine whether ADHD subgroups differ based on neurocognitive and demographic factors in 179 adult patients with ADHD. Latent Profile Analysis (LPA) revealed four discrete latent subgroups within the sample, each with distinct patterns of working memory and processing speed. Classes significantly differed in demographically predicted IQ, education, and self-reported depression and anxiety. Results reveal heterogeneity in cognitive performance in adult ADHD.

摘要

本研究根据韦氏成人智力量表第四版(WAIS-IV) 工作记忆和处理速度指数检查了注意力缺陷/多动障碍 (ADHD) 患者的神经心理学特征。我们旨在确定是否基于神经心理学测试出现不同的 ADHD 亚型，并根据 179 名成年 ADHD 患者的神经认知和人口统计学因素确定 ADHD 亚组是否存在差异。潜在概况分析 (LPA) 揭示了样本中的四个离散潜在子组，每个子组具有不同的工作记忆和处理速度模式。班级在人口统计预测的智商、教育和自我报告的抑郁和焦虑方面存在显着差异。结果揭示了成人 ADHD 认知表现的异质性。
