Introduction There has been a significant increase in average life expectancy. This increase brought more focus on aging with more health, autonomy and independence. Among current public health concerns, the detection of cognitive decline in older individuals stands out, namely in Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI). Accurate, brief, practical and automated measures are needed to assess cognitive function throughout the life-span. Since 2015, there is the NIH Toolbox Cognition Battery (NIHTB-CB) app that meets these requirements and assesses the neurocognitive subdomains of attention, episodic memory, executive function, language, processing speed, and working memory. The European Portuguese app, developed by our team, will be validated for the Portuguese older adults. Objectives The aim is presenting a literature review of the use of NIHTB-CB in healthy aging and cognitive decline in MCI and AD. Methodology Advanced search in the databases of Web of Science and Google Scholar for studies published between 2016-2019, including articles and meeting abstracts with the words: NIH Toolbox Cognition Battery, AD, MCI, Elder or Senior or Older. Results According to the studies reviewed, NIHTB-CB may be useful in memory clinics (e.g.Hackett et al, 2018; Mayeda et al. 2018); clinical trials (e.g.Buckley et al., 2017; Parsey, Bagger & Hanson, 2019); and healthy aging (e.g.Scott, Sorell, & Benitez, 2019). Preliminary results of the ARMADA study (Weintraub et al, 2019) with people with more than 85 years old became available showing that generally, NIHTB-CB is well accepted, also in MCI patients. No difficulties were found in the use of the iPad with older adults. Conclusion NIHTB-CB measures provide a valid assessment of neurocognitive domains that are important in healthy aging, MCI and AD. As the studies are still scarce, more research is needed.
