项目摘要
PROJECT SUMMARY
Dementia is the most expensive medical condition in the US. There is an urgent need to intervene to curb
the increasing prevalence of dementia in our population. Strong preliminary data from more than 18 ran-
domized clinical trials demonstrate that computerized, cognitive speed of processing training (SPT) im-
proves cognition and transfers to improved instrumental activities of daily living. Recent evidence further
indicates that SPT may reduce dementia risk. Analyses of 10-year data from the ACTIVE trial revealed
that older adults randomized to SPT were 29% less likely to develop dementia. Moreover, those who com-
pleted additional training had a 48% reduced risk of dementia across 10 years. Two limitations of this
study were a lack of clinical diagnosis of dementia and use of a no-contact control condition. Thus, an im-
portant question is, “Can SPT be successfully implemented to reduce incidence of mild cognitive impair-
ment (MCI) or dementia?”. Our primary goal is to test the effectiveness of SPT to reduce incidence
of MCI or dementia. The Preventing Alzheimer's with Cognitive Training-PACT field trial advances prior
research by rigorously implementing SPT in a large population of cognitively normal older adults and ex-
amining the primary endpoint of MCI or dementia clinical diagnoses. Older adults are randomized to SPT
or an active control arm of cognitive stimulation (i.e., computer games) and progression to MCI or demen-
tia will be clinically assessed after 3 years. We further will explore if SPT effects are moderated by the de-
gree of amyloid pathology or apolipoprotein E4 status. To demonstrate feasibility, our investigative team is
implementing the study protocol in an R56 phase and successfully enrolled 744 older adults at the time of
proposal submission. Three years after enrollment, we will re-assess study participants to identify those
exhibiting cognitive decline. Such participants will be provided a thorough medical evaluation to clinically
ascertain MCI or dementia diagnosis. Those classified as MCI or dementia will further complete an amy-
loid PET scan and genetic testing. This non-pharmacological prevention trial is innovative with a highly
efficient experimental design and optimized SPT training protocols including an active control group. The
proposed research will determine if SPT successfully reduces incidence of MCI or dementia. This out-
come will be significant in that if an intervention can delay the onset of dementia by only one year, there
will be ~9.2 million fewer cases of the disease by 2050, substantially reducing cost. Positive results would
support use of a relatively inexpensive and easy to apply intervention that could delay or prevent the on-
set of Alzheimer’s disease and/or related dementias. Such an outcome would justify further research to
identify mechanisms of action. Results will inform clinical practice of effective interventions to attenuate
age-related cognitive and functional decline and thereby improve public health.
项目总结
痴呆症是美国最昂贵的医疗疾病。迫切需要进行干预以遏制
我们人口中痴呆症的患病率越来越高。来自18个RAN的强劲初步数据-
临床试验表明,计算机化的认知加工速度训练(SPT)能有效地提高患者的心理健康水平。
证明认知,并转移到日常生活中改善的工具性活动。最近的证据进一步
表明SPT可以降低患痴呆症的风险。对积极试验的10年数据的分析揭示了
随机参加SPT的老年人患痴呆症的可能性降低29%。此外,前来的人-
经过10年的额外训练,患痴呆症的风险降低了48%。这有两个局限性
研究缺乏痴呆症的临床诊断和非接触性对照条件的使用。因此,一个即时消息-
重要的问题是,能否成功地实施特殊目的测试,以减少轻度认知障碍的发生率-
痴呆症(MCI)还是痴呆症?“我们的主要目标是测试SPT的有效性,以减少发病率
患有MCI或痴呆症。认知训练预防阿尔茨海默病-PACT现场试验进展
通过在大量认知正常的老年人和前老年人中严格实施SPT进行的研究
寻找MCI或痴呆临床诊断的主要终点。老年人被随机分配到特殊目的人群中
或认知刺激的主动控制臂(例如,电脑游戏),并进展到MCI或Demen-
TIA将在3年后进行临床评估。我们将进一步探讨SPT效应是否会因
淀粉样变或载脂蛋白E4状态。为了证明可行性,我们的调查小组
在R56阶段实施研究方案,并成功招募了744名老年人
提交建议书。注册三年后,我们将重新评估研究参与者,以确定哪些
表现出认知能力下降的。这些参与者将被提供一个全面的医学评估,以临床
确定MCI或痴呆的诊断。那些被归类为MCI或痴呆症的人将进一步完成AMY-
Loid PET扫描和基因检测。这项非药物预防试验具有创新性,具有高度的
高效的实验设计和优化的SPT训练方案,包括一个积极的对照组。这个
拟议的研究将确定SPT是否成功地降低了MCI或痴呆症的发病率。这件事就是-
如果一项干预措施仅能将痴呆症的发病推迟一年,这一点将具有重大意义。
到2050年,这种疾病的病例将减少约920万例,大大降低成本。积极的结果将
支持使用相对便宜且易于应用的干预措施,以延迟或阻止
一组阿尔茨海默病和/或相关痴呆症。这样的结果将证明进一步的研究是合理的
确定行动机制。结果将为临床实践提供有效的干预措施,以减轻
与年龄相关的认知和功能下降,从而改善公共健康。
