HIGH DOSE SUPPLEMENTS TO REDUCE HOMOCYSTEINE AND SLOW THE RATE OF COGNITIVE

这个子项目是众多研究子项目之一

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. SPECIFIC AIMS: Primary: 1. Determine whether reduction of homocysteine levels with high-dose folic acid/B6/B12 supplementation will slow the rate of cognitive decline in subjects with AD Secondary: 2. Determine whether reduction of homocysteine levels with high-dose folic acid/B6/B12 supplementation will slow the rate of clinical decline, as measured by the time to reach clinically significant end-points, in subjects with AD 3. Determine whether reduction of homocysteine levels with high-dose folic acid/B6/B12 supplementation will favorably influence measures of behavior, activities of daily living, global status, and quality of life in subjects with AD 4. Examine the influence of apolipoprotein E and methylenetetrahydrofolate reductase (MTHFR) genotype on homocysteine reduction in subjects with AD 5. Determine the safety and tolerability of long-term treatment of AD subjects with high-dose supplements
