视觉建构能力是痴呆症评估的一个重要领域。使用图表的措施占主导地位，这一领域，然而，低教育程度的参与者产生的结果，不能很容易地解释。我们的目的是开发和验证一种用于低教育或无教育人群痴呆评估的视觉建构能力的非图形学评估。在一项对尼日利亚伊巴丹约鲁巴居民（65岁及以上）进行的以人群为基础的痴呆症纵向研究中，参与者接受了一系列认知测试和共识诊断的临床评估。两个visuostructural测试，施工实践和坚持设计，性能进行了比较。性别、年龄和教育程度影响了这两项测试的表现。根据总测试失败的参与者数量（3.9% vs. 15.1%）衡量，Stick Design测试比Constructional Praxis更可接受。棍子设计测试对认知障碍和痴呆症的敏感性明显高于结构实践测试。我们的结论是，坚持设计是一个合理的测试，在年龄较大的同龄人的视觉建构能力非常有限的教育曝光和识字。
Visuoconstructional ability is an important domain for assessment in dementia. Use of graphomotor measures dominate this area; however, participants with low education produce results that cannot be easily interpreted. Our objective was to develop and validate a nongraphomotor assessment of visuoconstructional ability for use in dementia evaluations in persons with low or no education. In a longitudinal, population-based study of dementia among Yoruba residents of Ibadan, Nigeria aged 65 years and older, participants underwent clinical assessment with a battery or cognitive tests and consensus diagnosis. Performance on two visuoconstructional tests, Constructional Praxis and Stick Design, were compared. Gender, age, and education affected performance on both tests. The Stick Design test was more acceptable than Constructional Praxis as measured by the number of participants with total test failure (3.9% vs. 15.1%). The Stick Design test was significantly more sensitive to cognitive impairment and dementia than the Constructional Praxis test. We conclude that Stick Design is a reasonable test of visuoconstructional ability in older cohorts with very limited educational exposure and literacy.
