Abstract
Increased levels of total homocysteine (tHcy) have been associated with lower performance on tests of cognitive function, and may be a potential preclinical marker for Alzheimer's disease. Most reports have focused on older cohorts, but raised tHcy levels, in association with cognitive changes may be occurring in earlier years. Scores for verbal and working memory were compared to plasma homocysteine levels for 200 healthy women aged 56--67 (mean=60). Smoking, hormone therapy and age were significantly associated with increased levels of tHcy, whilst vitamin B or folate supplements were significantly associated with lower tHcy levels. Hyperhomocysteinemia (>13 micromol/l) was significantly a..
