ABSTRACT

Cognitive impairment, particularly slowing of information processing speed (IPS), is prevalent after stroke. However, the link between subjective cognitive complaints (SCC) and cognitive deficit remains unclear. This study evaluated the link between SCC at three months post stroke and deficit as well as objective alterations in IPS in the first year post stroke. Patients (N = 200) and healthy controls (N = 105) took part in the COMPlaints After Stroke study (COMPAS). SCC, IPS and depression were evaluated at 3 months, 1 and 2 years post stroke. The Reliable Change Index was used to assess change in IPS in the first year post. Approximately one out of three patients showed deficit in IPS irrespective of time post stroke, while a change in IPS (N = 117) over time was relatively uncommon. SCC at three months post stroke did not predict change in IPS between three months and one year post stroke, where depressive symptoms did show a link. Cross sectional data showed a deficit in IPS in a substantial number of stroke patients irrespective of the point in time. Longitudinal data revealed a further decline in a small subgroup in the first year post stroke, which was not predicted by SCC at three months post stroke. The findings show that, irrespective of time post stroke and even when stroke is relatively mild, impairment in IPS is prevalent, but cannot be predicted by the complaints patients express. The link with depressive symptoms needs more exploration.

中风后三个月的主观认知投诉能否预测第一年信息处理速度的变化?

摘要

中风后普遍存在认知障碍,尤其是信息处理速度 (IPS) 减慢。然而,主观认知抱怨 (SCC) 与认知缺陷之间的联系仍不清楚。本研究评估了中风后三个月的 SCC 与缺陷之间的联系,以及中风后第一年 IPS 的客观变化。患者 (N = 200) 和健康对照 (N = 105) 参加了中风后投诉研究 (COMPAS)。在卒中后 3 个月、1 年和 2 年评估 SCC、IPS 和抑郁症。可靠变化指数用于评估 IPS 在第一年的变化。无论中风后时间如何,大约三分之一的患者显示 IPS 缺陷,而 IPS 随时间的变化 (N = 117) 相对不常见。卒中后三个月的 SCC 并不能预测 IPS 在卒中后三个月到一年之间的变化,抑郁症状确实显示出一种联系。横断面数据显示大量中风患者的 IPS 缺陷,与时间点无关。纵向数据显示,在中风后第一年,一小部分人进一步下降,而 SCC 在中风后三个月没有预测到这一点。研究结果表明,无论中风后的时间如何,即使中风相对较轻,IPS 损伤也很普遍,但无法通过患者表达的抱怨来预测。与抑郁症状的联系需要更多探索。横断面数据显示大量中风患者的 IPS 缺陷,与时间点无关。纵向数据显示,在中风后第一年,一小部分人进一步下降,而 SCC 在中风后三个月没有预测到这一点。研究结果表明,无论中风后的时间如何,即使中风相对较轻,IPS 损伤也很普遍,但无法通过患者表达的抱怨来预测。与抑郁症状的联系需要更多探索。横断面数据显示大量中风患者的 IPS 缺陷,与时间点无关。纵向数据显示,在中风后第一年,一小部分人进一步下降,而 SCC 在中风后三个月没有预测到这一点。研究结果表明,无论中风后的时间如何,即使中风相对较轻,IPS 损伤也很普遍,但无法通过患者表达的抱怨来预测。与抑郁症状的联系需要更多探索。但不能通过患者表达的抱怨来预测。与抑郁症状的联系需要更多探索。但不能通过患者表达的抱怨来预测。与抑郁症状的联系需要更多探索。
