本研究的目的是探讨囤积症（HD）成人患者的主观认知功能障碍。83名HD患者和46名年龄和性别匹配的健康对照（HC）参与者接受了诊断性访谈，并完成了主观认知功能和储蓄行为动机的测量，以及囤积严重程度，抑郁，焦虑，压力和强迫症（OCD）症状的测量。HD组在记忆、注意力分散、失误、名字记忆和注意力不集中等方面的损害比HC组更多。当控制共病症状时，这些差异通常仍然显著。在HD组中，认知功能障碍的程度与储蓄和获取行为的严重程度显著相关，尽管在控制共病症状时结果有所减弱（总体HD严重程度，而不是储蓄行为，仍然与认知功能障碍显著相关）。主观认知障碍进一步与保存财产以避免遗忘的愿望相关，当控制共病症状时，这些结果仍然显着。这些结果符合当前HD的行为模型，强调决策缺陷，以及临床观察提示认知功能受损，并补充了越来越多的神经心理学测试研究。
The aim of the present study was to examine subjective cognitive impairment among adult patients with hoarding disorder (HD). Eighty-three patients with HD and 46 age- and gender-matched healthy control (HC) participants received a diagnostic interview and completed measures of subjective cognitive functioning and motivations for saving behavior, as well as measures of hoarding severity, depression, anxiety, stress, and obsessive-compulsive disorder (OCD) symptoms. The HD group reported more impairment than did the HC group in domains of memory, distractibility, blunders, memory for names, and inattention. These differences generally remained significant when controlling for comorbid symptoms. In the HD group, the degree of cognitive impairment was significantly correlated with severity of saving and acquiring behaviors, although results were attenuated when controlling for comorbid symptoms (overall HD severity, but not saving behavior specifically, remained significantly correlated with cognitive impairment). Subjective cognitive impairment was further associated with a desire to save possessions in order to avoid forgetting, and these results remained significant when controlling for comorbid symptoms. These results comport with current behavioral models of HD that emphasize decision-making deficits, as well as clinician observations suggestive of impaired cognitive function, and complement a growing body of neuropsychological testing studies.
