Abstract

Objective: To determine the efficacy of a 12-week individual cognitive stimulation (iCS) intervention on global cognition, memory, and executive function of older adults with mild to moderate Alzheimer's disease (AD).

Method: Protocolized analysis using data from a multicenter, single-blind, randomized, parallel two-arm RCT of iCS for older adults with probable AD. A sample of 142 people with probable Alzheimer's disease attending 13 Portuguese institutions providing care and support services for older adults were selected. Intervention group (n = 72) received 24 iCS sessions, twice a week for 12 weeks. Control group (n = 70) maintained their activities as usual. Outcomes included global cognitive function (Mini-Mental State Examination, and Alzheimer's Disease Assessment Scale-Cognitive Subscale), memory (Memory Alteration Test, and Free and Cued Selective Reminding Test), and executive functioning (Frontal Assessment Battery). All participants were assessed at baseline (T0), after the intervention (T1), and 12 weeks follow-up (T2).

Results: The results showed significant improvements in memory performance at follow-up for the intervention group and greater stability in global cognition in the intervention relative to the control group.

Conclusion: The current iCS protocol shows effectiveness in cognitive functioning in older adults with probable AD, particularly for memory upon completion of the intervention and at follow-up, adding further support to previous iCS studies showing similar results and to the effectiveness of the current intervention.

个体认知刺激干预对轻度至中度阿尔茨海默氏症老年人的整体认知、记忆和执行功能的影响。

目的确定为期 12 周的个体认知刺激（iCS）干预对轻度至中度阿尔茨海默病（AD）老年人的整体认知、记忆和执行功能的疗效：方法：利用一项针对可能患有阿尔茨海默病的老年人的多中心、单盲、随机、平行双臂 RCT 数据进行协议分析。选取了葡萄牙 13 家为老年人提供护理和支持服务的机构中的 142 名疑似阿尔茨海默病患者作为样本。干预组（n = 72）接受 24 节 iCS 课程，每周两次，为期 12 周。对照组（n = 70）照常活动。研究结果包括总体认知功能（迷你精神状态检查和阿尔茨海默病评估量表-认知分量表）、记忆力（记忆改变测试和自由及提示选择性记忆测试）和执行功能（前额评估电池）。对所有参与者进行了基线（T0）、干预后（T1）和 12 周随访（T2）评估：结果表明，干预组在随访时的记忆表现有明显改善，干预组相对于对照组的整体认知稳定性更高：结论：目前的 iCS 方案显示出对可能患有注意力缺失症的老年人认知功能的有效性，尤其是在完成干预后和随访时的记忆力，这进一步支持了之前显示出类似结果的 iCS 研究以及目前干预的有效性。

期刊介绍： The Clinical Neuropsychologist (TCN) serves as the premier forum for (1) state-of-the-art clinically-relevant scientific research, (2) in-depth professional discussions of matters germane to evidence-based practice, and (3) clinical case studies in neuropsychology. Of particular interest are papers that can make definitive statements about a given topic (thereby having implications for the standards of clinical practice) and those with the potential to expand today’s clinical frontiers. Research on all age groups, and on both clinical and normal populations, is considered.
