Association Between Metabolic Syndrome and Decline in Cognitive Function: A Cross-Sectional Study.

Aim: We investigated whether metabolic syndrome (MetS) is associated with a decline in cognitive function in a cohort of middle-aged and elderly individuals without known cognitive dysfunction diseases in Qatar.

Methods: We conducted a cross-sectional study on randomly selected participants aged 40-80 years from the Qatar Biobank, with data on cognitive tests and MetS components. Participants with a history of dementia, stroke, or mental disorders were excluded.
