Behavioural and Psychological Symptoms of Alzheimer Type Dementia Are Not Correlated with Plasma Homocysteine Concentration

Abstract

This study shows for the first time that BPSD are not associated with hyperhomocysteinaemia in Alzheimer dementia. Although previous studies have identified homocysteine as an independent risk factor in AD, the results reported here do not lend weight to an aetiological role for homocysteine specifically in BPSD.
