Prevalence and Factors Associated with Mild Neurocognitive Disorder and Dementia in Pre-retirement Personnel of King Narai Hospital, Lopburi Province

Abstract

Objective: To identify prevalence of Mild Neurocognitive Disorder (MND) and Dementia by using Montreal Cognitive Assessment test (MoCA-T) and Addenbrooke's Cognitive Examination III (ACE-T) test and to identify associated factors. Methods: Cross-sectional descriptive study which covered almost 188 pre-retirement hospital personnel, aged 50-60 years during July 2023.Tools include personal information form, Body Mass Index and two specific brain function tests including MoCA-T and ACE-T.  Descriptive statistics, Chi-square analysis, Ordinal Logistic Regression and Multiple Ordinal Logistic Regression have been used to identify prevalence and associated factors to MND and Dementia. Results: The 23.9% prevalence of dementia and 33.5% of MND and  25.4% of Amnestic MND with MoCA-T test, and 3.7% of dementia, 19.1% of MND with ACE-T were found. The findings showed low concordance between both tools with a Kappa = 0.209. Factors associated with Dementia include Educational level (both MoCA-T and ACE-T), Marital Status, Chronic Disease, Exercise (MoCA-T only) and Occupation (ACE-T only). Conclusion:  MND and Dementia tends to be increasing. Primary care units should establish comprehensive screening and referral systems for confirmed diagnosis and proper management. The appropriate age for screening should be considered based on local context and preventable risk factors should be addressed.
