The burden of missing incidents due to wandering with dementia is not only on the patient but also on their family, neighbors, and community. In this study, we conducted a non-randomized prospective one-year followup cohort study based on symptom registration with missing cases due to wandering with dementia as the endpoint. The incidence and recurrence rates of missing events were calculated. Furthermore, analysis of variance and logistic regression analysis were performed to clarify the risk factors associated with the missing event. Among the 236 patients with dementia enrolled, 65 (27.5%) had a previous missing event at baseline. Of the 65 patients with dementia who had a previous missing event at baseline, 28 had a missing event during the oneyear follow-up period (recurrence rate of 43.1%). Of the 171 who did not have a previous missing event at baseline, 23 had a missing event during the one-year follow-up period (incidence rate of 13.5%). Prevention of missing events requires focused attention on changes in the Mini-Mental State Examination, Dementia Behavior Disturbance Scale, Alzheimer's Disease Assessment Scale scores, and the development of a social environment for supporting family caregivers.
