The cognitive function after stroke is examined in acute and subacute phase, but poorly characterized in long-term stroke survivors. This paper discusses cognitive function among long-term stroke survivors, with matched stroke-free subjects, based on a population survey. General cognition, verbal, executive and visuospatial function, memory, attention, and motor speed were tested as well as motor function in upper extremities. Stroke survivors and controls were most effectively discriminated by means of motor speed, followed by visuospatial episodic memory and verbal fluency. This pattern of cognitive disturbances may be a consequence of cerebral lesions in frontal subcortical areas, and is different from Alzheimer's disease.
中风后的认知功能在急性期和亚急性期会进行检查，但在长期中风幸存者中其特征描述不足。本文基于一项人群调查，讨论了长期中风幸存者与匹配的无中风受试者之间的认知功能。测试了一般认知、语言、执行和视觉空间功能、记忆、注意力、运动速度以及上肢运动功能。通过运动速度，其次是视觉空间情景记忆和语言流畅性，最有效地区分了中风幸存者和对照组。这种认知障碍模式可能是额叶皮质下区域脑损伤的结果，且与阿尔茨海默病不同。
