In individuals with subjective cognitive impairments (SCI) the risk for the development of a neurodegenerative disease is assumed to be increased. However, it is not clear which factors contribute to the expression of SCI: Is it related to the cognitive resources already challenged, or is the psycho-affective state of more relevance? Using a novel online assessment combining self-report questionnaires and neuropsychological psychometric tests, significant predictors for the level of complaints were identified in two samples of elderly individuals: Help-seekers (HS, n = 48) consulting a memory clinic and a matched sample of non-help-seekers (nHS, n = 48). Based on the results of the online assessment, the SCI level was found to be significantly determined by the psycho-affective state (depressive mood) in the nHS group, whereas cognitive performance (cued recall) was the main predictor in the HS group. The predictive value of recall performance, however, is more-strongly expressed in memory tests which reduce the impact of compensatory strategies (face-name-association vs. word lists). Our results indicate that the problem-focused behavior of help-seeking individuals is also associated with a higher sensitivity for cognitive deficits-which can be uncovered with an appropriate psychometric test. Considering these factors, the conversion risk in individuals with SCI can probably be determined more reliably.
在有主观认知障碍(SCI)的个体中,发展为神经退行性疾病的风险被认为会增加。然而,哪些因素导致 SCI 的表现尚不清楚:这与已经受到挑战的认知资源有关,还是与心理-情感状态更相关?本研究使用一种新颖的在线评估方法,结合自我报告问卷和神经心理学心理计量测试,在两个老年个体样本中识别出了与抱怨水平相关的显著预测因素:寻求帮助者(HS,n=48),他们咨询了记忆诊所,以及匹配的无帮助寻求者样本(nHS,n=48)。基于在线评估的结果,在 nHS 组中,SCI 水平明显由心理-情感状态(抑郁情绪)决定,而在 HS 组中,认知表现(线索回忆)是主要预测因素。然而,在减少补偿策略影响的记忆测试中(面孔-名字联想对单词列表),回忆表现的预测价值表达得更为强烈。我们的研究结果表明,寻求帮助的个体的问题导向行为也与更高的认知缺陷敏感性有关,这可以通过适当的心理计量测试揭示出来。考虑到这些因素,SCI 个体的转化风险可能可以更可靠地确定。
