India's distinct culture and demographics warrant investigation into population‐specific cutoffs.MethodsData were utilized from the Longitudinal Aging Study in India‐Diagnostic Assessment of Dementia (n = 2528). Dementia ascertainment was conducted by an online panel. A machine learning (ML) model was trained on these classifications, with explainable artificial intelligence to assess feature importance and inform cutoffs that were assessed across demographic groups.ResultsThe Informant Questionnaire of Cognitive Decline in the Elderly (IQCODE) and Hindi Mini‐Mental State Examination (HMSE) were identified as the most impactful assessments with optimal cutoffs of 3.8 and 25, respectively.DiscussionAn ML assessment of clinician dementia ratings identified IQCODE and HMSE to be the most impactful assessments. Optimal cutoffs of 3.8 and 25 were identified and performed excellently in the overall sample, though did decrease in specific, more difficult‐to‐diagnose subgroups.Highlights Pioneers use of explainable artificial intelligence in the diagnosis of dementia. Creates assessment cutoffs specific to the nation of India. Highlights differences in cutoffs across nations. 10.1002/dad2.70049 http://creativecommons.org/licenses/by/4.0/ |
