Visual Agnosia01:12

Visual Agnosia

974
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Prosopagnosia

702
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

此摘要是机器生成的。

患有持续视力缺陷 (PeVD) 的轻度缺血性中风 (MIS) 患者的中风严重程度较高,但90天的功能结果没有恶化. 需要进一步的研究来探索在MIS中对PeVD的替代结果措施.

科学领域:

  • 神经学 神经学
  • 脑卒中医学 脑卒中医学
  • 临床结果研究研究

背景情况:

  • 与严重中风相比,轻度缺血性中风 (MIS) 的结果是不太了解的.
  • 在MIS中预测长期结果的预测器需要进一步研究.
  • 持续视力缺陷 (PeVD) 对MIS功能障碍的影响还没有得到充分的描述.

研究的目的:

  • 为了比较MIS患者与没有PeVD的功能结果.
  • 评估MIS后PeVD和长期功能残疾之间的关联.

主要方法:

  • 成年急性缺血性中风患者的回顾性单中心队列研究 (2019-2023年).
  • 根据国家卫生研究院中风量表 (NIHSS) 定义的MIS,入院时的得分≤5和24小时.
  • 24小时以非零视野NIHSS子评分定义的PeVD;主要结果是90天修改的兰金尺度 (mRS).

主要成果:

  • 在1041名MIS患者中,有10.4%患有PeVD.
  • 患有PeVD的患者具有更高的呈现和24小时NIHSS得分.
  • PeVD与更高的90天死亡率和mRS得分有关,但多变量分析表明24小时NIHSS,而不是PeVD,预测了更糟糕的功能结果.

结论:

  • 少数MIS患者经历了PeVD.
  • PeVD与中风的严重程度有关,但与90天的功能结果无关.
  • 对于患有PeVD的MIS患者,应探索超越mRS的替代功能结果措施.
