Diet Quality and Dementia Risk in Older Adults With Alzheimer Pathology.
Higher diet quality associates with lower dementia risk among people with early Alzheimer's pathology, suggesting dietary changes may help prevent symptom onset.
In a prospective Swedish cohort with Alzheimer pathology confirmed by amyloid PET or CSF biomarkers, higher diet quality was associated with significantly lower dementia risk, suggesting dietary intervention may slow clinical conversion in individuals with preclinical AD. JAMA Network Open publication from Karolinska/NVS group provides strong epidemiological grounding for dietary modification in the secondary prevention of Alzheimer disease.
