Topographical disorientation is a common and early manifestation of dementia of Alzheimer type, which threatens independence in activities of daily living. Errorless-based techniques appear to be effective in helping patients with amnesia to learn routes, but little is known about their effectiveness in early dementia of Alzheimer type. A 77-year-old woman with dementia of Alzheimer type had difficulty in finding her way around her seniors residence, which reduced her social activities. This study used an ABA design (A is the baseline and B is the intervention) with multiple baselines across routes for going to the rosary (target), laundry, and game rooms (controls). The errorless-based technique intervention was applied to 2 of the 3 routes. Analyses showed significant improvement only for the routes learned with errorless-based techniques. Following the study, the participant increased her topographical knowledge of her surroundings. Route learning interventions based on errorless-based techniques appear to be a promising approach for improving the independence in early dementia of Alzheimer type.
地形定向障碍是阿尔茨海默病型痴呆常见的早期表现，它会威胁到日常生活活动的独立性。基于无错误学习的技术似乎能有效帮助失忆患者学习路线，但对于其在阿尔茨海默病型早期痴呆中的有效性却知之甚少。一名77岁的阿尔茨海默病型痴呆女性在其老年公寓内难以找到方向，这减少了她的社交活动。本研究采用ABA设计（A为基线，B为干预），对前往玫瑰经祈祷室（目标地点）、洗衣房和游戏室（对照地点）的多条路线设置多个基线。基于无错误学习的技术干预应用于三条路线中的两条。分析表明，只有通过基于无错误学习技术学习的路线有显著改善。研究结束后，参与者增加了对周围环境的地形知识。基于无错误学习技术的路线学习干预似乎是提高阿尔茨海默病型早期痴呆患者独立性的一种有前景的方法。
