Results group good (Area Under Curve = 0.879) CDFAQ‐IV total score, excellent EF domain (AUC 0.907), LM 0.822) poor accuracies other domains. For group, 0.908) 0.914) showed accuracies, while CA 0.876), L 0.832) SC 0.814) domains accuracies. others (0.924) accuracy, CDFAQ’s score 0.894) 0.898) accuracy.
