Specific Nutritional Biomarker Profiles in Mild Cognitive Impairment and Subjective Cognitive Decline Are Associated With Clinical Progression: The NUDAD Project

Nutritional insufficiencies have been associated with cognitive impairment. Understanding whether nutritional biomarker levels are associated with clinical progression could help to design dietary intervention trials. This longitudinal study examined a panel of nutritional biomarkers in relation to clinical progression in patients with subjective cognitive decline (SCD) or mild cognitive impairment (MCI).
