Despite the plethora of in-person cognitive tests, those that can be administered over the phone are lacking. We hypothesized that a home-based cognitive test (HCT) using phone calls would be feasible and useful in non-demented elderly. We aimed to assess feasibility and validity of a new HCT as an optional cognitive monitoring tool without visiting hospitals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Our study was conducted in a prospective design during 24 weeks. We developed a new HCT consisting of 20 questions (score range 0\u201330). Participants with MCI (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200938) were consecutively enrolled and underwent regular HCTs during 24 weeks. Associations between HCT scores and in-person cognitive scores and Alzheimer\u2019s disease (AD) biomarkers were evaluated. In addition, HCT scores in MCI participants were cross-sectionally compared with age-matched cognitively normal (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200930) and mild AD dementia (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200917) participants for discriminative ability of the HCT.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      HCT had good intra-class reliability (test-retest Cronbach\u2019s alpha 0.839). HCT scores were correlated with the Mini-Mental State Examination (MMSE), verbal memory delayed recall, and Stroop test scores but not associated with AD biomarkers. HCT scores significantly differed among cognitively normal, MCI, and mild dementia participants, indicating its discriminative ability. Finally, 32 MCI participants completed follow-up evaluations, and 8 progressed to dementia. Baseline HCT scores in dementia progressors were lower than those in non-progressors (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The feasibility and usefulness of the HCT were demonstrated in elderly subjects with MCI.
