The final sample comprised 74 Healthy controls, 190 individuals with MCI, and 326 with Dementia (including 269 with Alzheimer's disease). Scores from the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Japanese version (MoCA-J), Rivermead Behavioural Memory Test (RBMT), Japanese Adult Reading Test (JART), and Wechsler Adult Intelligence Scale-III were input into a random forest machine learning model. Model performance was assessed using the area under the ROC curve (AUC). A variable importance analysis determined each test's relative contribution to classification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The multiclass model achieved an AUC of 0.898.
