分析脑损伤患者视觉症状与客观测试的关系,发现主观抱怨与检测结果关联弱。
Exploring Visual Complaints through a test battery in Acquired Brain Injury Patients: A Detailed Analysis of the DiaNAH Dataset
- 用AutoML处理缺失数据,保留原始分布特征
- 767名患者分出4万多种症状组合,但抱怨与测试无强相关
- 为理解脑损伤后视觉问题提供新视角,适合康复研究者
本研究基于948名获得性脑损伤(ABI)患者的DiaNAH数据集,调查其视觉障碍主诉。患者完成包含八类视觉症状的CVS问卷,如视力模糊和对比度感知异常。因数据不全,181人被排除,最终分析样本为767人。针对缺失数据问题,采用自动化机器学习(AutoML)方法进行数据填补,保持原数据分布特性。根据CVS问卷识别出40,320种可能的症状组合,将患者按单一或复合症状群分类。线性相关分析显示,患者自述视觉症状与标准视觉感知功能测试之间关联微弱或无直接关联。该研究是首次系统探讨ABI患者主观视觉抱怨与客观感知评估间复杂关系的尝试。鉴于样本量有限及个体差异,建议未来开展更大规模研究以深入探索这些症状群及其对脑损伤后视觉感知的影响。
原文摘要 · Abstract (English)
This study investigated visual impairment complaints in a sample of 948 Acquired Brain Injury (ABI) patients using the DiaNAH dataset, emphasizing advanced machine learning techniques for managing missing data. Patients completed a CVS questionnaire capturing eight types of visual symptoms, including blurred vision and altered contrast perception. Due to incomplete data, 181 patients were excluded, resulting in an analytical subset of 767 individuals. To address the challenge of missing data, an automated machine learning (AutoML) approach was employed for data imputation, preserving the distributional characteristics of the original dataset. Patients were grouped according to singular and combined complaint clusters derived from the 40,320 potential combinations identified through the CVS questionnaire. A linear correlation analysis revealed minimal to no direct relationship between patient-reported visual complaints and standard visual perceptual function tests. This study represents an initial systematic attempt to understand the complex relationship between subjective visual complaints and objective visual perceptual assessments in ABI patients. Given the limitations of sample size and variability, further studies with larger populations are recommended to robustly explore these complaint clusters and their implications for visual perception following brain injury.
