In this study, we investigated whether unobtrusive in-house power monitoring technologies could be used to predict cognitive impairment. A total of 94 older adults aged \u226565 years were enrolled in this study. Generalized linear mixed models with subject-specific random intercepts were used to evaluate differences in the usage time of home appliances between people with and without cognitive impairment. Three independent power monitoring parameters representing activity behavior were found to be associated with cognitive impairment. Representative values of mean differences between those with cognitive impairment relative to those without were \u221213.5 min for induction heating in the spring, \u22121.80 min for microwave oven in the winter, and \u22120.82 h for air conditioner in the winter. We developed two prediction models for cognitive impairment, one with power monitoring data and the other without, and found that the former had better predictive ability (accuracy, 0.82; sensitivity, 0.48; specificity, 0.96) compared to the latter (accuracy, 0.76; sensitivity, 0.30; specificity, 0.95). In summary, in-house power monitoring technologies can be used to detect cognitive impairment.<\/jats:p>","DOI":"10.3390\/s21186249","type":"journal-article","created":{"date-parts":[[2021,9,21]],"date-time":"2021-09-21T22:35:20Z","timestamp":1632263720000},"page":"6249","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["AI-Assisted In-House Power Monitoring for the Detection of Cognitive Impairment in Older Adults"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3100-574X","authenticated-orcid":false,"given":"Yuriko","family":"Nakaoku","sequence":"first","affiliation":[{"name":"Department of Preventive Medicine and Epidemiology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soshiro","family":"Ogata","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Epidemiology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1670-020X","authenticated-orcid":false,"given":"Shunsuke","family":"Murata","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Epidemiology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Nishimori","sequence":"additional","affiliation":[{"name":"Division of Epidemiology, Kobe University Graduate School of Medicine, Kobe 650-0017, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7102-4048","authenticated-orcid":false,"given":"Masafumi","family":"Ihara","sequence":"additional","affiliation":[{"name":"Department of Neurology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Iihara","sequence":"additional","affiliation":[{"name":"National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Misa","family":"Takegami","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Epidemiology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kunihiro","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Epidemiology, National Cerebral and Cardiovascular Center, Suita 564-8565, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,17]]},"reference":[{"key":"ref_1","unstructured":"(2019).
