homocysteine (tHcy), dietary folate and vitamin B6. Methods 64 AD patients were matched …

Background: In cross-sectional studies, elevated plasma total homocysteine (tHcy)
concentrations have been associated with cognitive impairment and dementia. Incidence …

Background: There is a growing focus on nutritional therapy for Alzheimer's disease (AD),
and controversy exists regarding the association between AD and homocysteine (Hcy) …

Increased plasma total homocysteine (tHcy) levels are a known risk factor for vascular
disease and have been reported in association with cognitive impairment of old age …

Background: High concentrations of homocysteine and low concentrations of vitamin B-12
and folic acid are frequently observed in subjects with dementia. Objective: We assessed …

Background Evidence supports an independent association between plasma total
homocysteine concentrations and the risk of vascular disease. Recent epidemiologic studies …

Objectives: The aim of this study was to investigate whether an increase in total
homocysteine (tHcy) concentration with increasing age is due to diminishing serum …

Background: Elevated plasma total homocysteine (tHcy) concentrations are common in the
elderly and have been suggested to be a risk factor for dementia. Objective: In an elderly …

Background In cross-sectional studies, elevated plasma homocysteine levels have been
