INTRODUCTION Autism spectrum disorder (ASD) represents a heterogenous cluster of clinical phenotypes that are classically diagnosed by the time of adolescence. The possibility of late-life emergence of ASD has been poorly explored. METHODS To more fully characterize the possibility of late-life emergence of behaviors characteristic of ASD in mild cognitive impairment and AD, we surveyed caregivers of 142 older persons with cognitive impairment from the University of Kentucky Alzheimer's Disease Center Longitudinal Cohort using the Gilliam Autism Rating Scale-2. RESULTS Participants with high autism index ratings (autism "possible/very likely," n=23) reported significantly (statistically and clinically) younger age at the onset of cognitive impairment than those who scored in the autism "unlikely" range (n=119): 71.14±10.9 vs. 76.65±8.25 (P=0.034). In addition, those in the autism "possible/very likely" group demonstrated advanced severity of cognitive impairment, indicated by the Clinical Dementia Rating Scale Sum of Boxes scores. DISCUSSION Data demonstrate that ASD behaviors may seem de novo of degenerative dementia and such behaviors are more prevalent in those with early onset dementia. Further work elucidating a connection between ASD and dementia could shed light on subclinical forms of ASD, identify areas of shared neuroanatomic involvement between ASD and dementias, and provide valuable insights that might hasten the development of therapeutic strategies.

患有轻度认知障碍或早期痴呆的老年人群中自闭症谱系障碍的行为特征。

简介 自闭症谱系障碍 (ASD) 代表一组异质的临床表型,通常在青春期就诊断出来。ASD 晚年出现的可能性一直没有得到很好的探索。方法 为了更全面地描述晚年出现轻度认知障碍和 AD 中 ASD 行为特征的可能性,我们使用 Gilliam 自闭症评定量表调查了来自肯塔基大学阿尔茨海默病中心纵向队列的 142 名认知障碍老年人的照顾者-2。结果 自闭症指数评分高的参与者(自闭症“可能/非常可能”,n=23)报告说,认知障碍发作时的认知障碍发病年龄显着(统计和临床)比那些在自闭症“不太可能”范围内得分的参与者(n=119 ):71.14±10。9 对 76.65±8.25 (P=0.034)。此外,自闭症“可能/非常可能”组的人表现出认知障碍的严重程度,这由临床痴呆评定量表总和分数表示。讨论 数据表明,ASD 行为似乎是退行性痴呆的新发,这种行为在早发性痴呆患者中更为普遍。阐明 ASD 和痴呆之间联系的进一步工作可以阐明 ASD 的亚临床形式,确定 ASD 和痴呆之间共同的神经解剖学参与领域,并提供可能加速治疗策略发展的有价值的见解。由临床痴呆评定量表总和分数表示。讨论 数据表明,ASD 行为似乎是退行性痴呆的新发,这种行为在早发性痴呆患者中更为普遍。阐明 ASD 和痴呆之间联系的进一步工作可以阐明 ASD 的亚临床形式,确定 ASD 和痴呆之间共同的神经解剖学参与领域,并提供可能加速治疗策略发展的有价值的见解。由临床痴呆评定量表总和分数表示。讨论 数据表明,ASD 行为似乎是退行性痴呆的新发,这种行为在早发性痴呆患者中更为普遍。阐明 ASD 和痴呆之间联系的进一步工作可以阐明 ASD 的亚临床形式,确定 ASD 和痴呆之间共同的神经解剖学参与领域,并提供可能加速治疗策略发展的有价值的见解。
