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.

成人ADHD的工作记忆和加工速度的潜在特征。

本研究采用韦氏成人智力量表第四版(WAIS-IV)工作记忆和加工速度指标对注意缺陷/多动障碍(ADHD)患者的神经心理特征进行了检测。我们的目的是在179名成年ADHD患者的神经心理学测试中确定是否存在不同的ADHD亚型，并确定ADHD亚组是否基于神经认知和人口统计学因素而存在差异。潜在特征分析(LPA)揭示了样本中四个离散的潜在亚组，每个亚组都有不同的工作记忆和加工速度模式。各阶层在人口统计学预测的智商、教育程度、自我报告的抑郁和焦虑方面存在显著差异。结果揭示了成人ADHD患者认知表现的异质性。

期刊介绍： Devoted to exploring relationships between brain and behavior across the life span, Developmental Neuropsychology publishes scholarly papers on the appearance and development of behavioral functions, such as language, perception, and social, motivational and cognitive processes as they relate to brain functions and structures. Appropriate subjects include studies of changes in cognitive function—brain structure relationships across a time period, early cognitive behaviors in normal and brain-damaged children, plasticity and recovery of function after early brain damage, the development of complex cognitive and motor skills, and specific and nonspecific disturbances, such as learning disabilities, mental retardation, schizophrenia, stuttering, and developmental aphasia. In the gerontologic areas, relevant subjects include neuropsychological analyses of normal age-related changes in brain and behavioral functions, such as sensory, motor, cognitive, and adaptive abilities; studies of age-related diseases of the nervous system; and recovery of function in later life. Empirical studies, research reviews, case reports, critical commentaries, and book reviews are featured in each issue. By publishing both basic and clinical studies of the developing and aging brain, the journal encourages additional scholarly work that advances understanding of the field of lifespan developmental neuropsychology.
