The relationship between dehydration and etiologic subtypes of major neurocognitive disorder in older patients.

Purpose: Studies investigating associations between etiologic subtypes of major neurocognitive disorder (MND) and dehydration frequency are lacking. The aim of this study was to investigate the prevalence and risk factors of dehydration among older adults with and without MND (dementia), and across different etiologic subtypes of MND.

Methods: This cross-sectional study included adults aged ≥ 65 years old from one geriatric outpatient clinic.
