This study examines selected demographic, psychometric, and biological measures as predictors of visuospatial performance in a sample of 98 persons with mild to moderate dementia. Visuospatial performance was measured using standardized neuropsychology instruments, namely: Poppelreuter's figures, the clock test, and block design. Although multiple measures were initially correlated with performance on the selected visuospatial tests, the Mini-Mental State Examination was the exclusive predictor of Poppelreuter's figures and the clock test scores. For block design, years of education also contributed to the prediction model, but only among mildly demented persons. These results suggest that disease severity plays a dominant role in the prediction of visuospatial performance in dementia, particularly in more advanced stages of the disease. The differential role of education in predicting block design performance in mild vs. moderate dementia was also highlighted.
本研究考察了98名轻度至中度痴呆患者的部分人口统计学、心理测量学和生物学指标，以预测其视觉空间能力。视觉空间能力通过标准化神经心理学工具进行测量，具体如下：波佩尔罗伊特图形、时钟测试和积木设计。尽管多项指标最初与所选视觉空间测试的表现相关，但简易精神状态检查表是波佩尔罗伊特图形和时钟测试分数的唯一预测指标。对于积木设计，受教育年限也对预测模型有贡献，但仅在轻度痴呆患者中如此。这些结果表明，疾病严重程度在痴呆患者视觉空间能力的预测中起主导作用，尤其是在疾病的更晚期阶段。教育在预测轻度与中度痴呆患者积木设计表现中的不同作用也得到了凸显。
