MDD(Mild Cognitive Impairment Delirium Dementia) Cohort

28. juli 2022 opdateret af: Kyoung ja Moon, Keimyung University Dongsan Medical Center

A Prospective, Longitudinal Cohort Study of the Incidence of Dementia After the Onset of Delirium in Patients With Mild Cognitive Impairment: MDD Cohort (Mild Cognitive Impairment Delirium Dementia)

  • Identify the degree of delirium in subjects with mild cognitive impairment and find the risk factors of delirium. Mortality, hospital stay, and medical expenses are analyzed as clinical consequences related to delirium incidence.
  • Dementia conversion rate and conversion period of subjects with mild cognitive impairment with delirium and it identifies the effect of delirium on dementia conversion.
  • Develop an AI(Artificial intelligence) algorithm for predicting dementia transition in subjects with mild cognitive impairment based on the research results of the 1st, 2nd, and 3rd years.
