Study Notes
- The study examines the effects of vitamin B administration on cognitive decline and hippocampal atrophy in patients with vitamin B deficiency.
- The efficacy of vitamin B supplementation in cognitive recovery remains controversial.
- Hyperhomocysteinemia (HHcy) is associated with cognitive impairment, brain atrophy, and Alzheimer's disease.
- Vitamin B deficiency can cause HHcy and oxidative stress, leading to cognitive impairment.
- Folate is also a cofactor involved in the remethylation of Hcy.
- Cognitive impairment is a progressive disease that puts a heavy burden on patients, their families, and society in today’s aging society.
- The study used the MMSE and VSRAD to evaluate cognitive decline and hippocampal atrophy.
- The study found a significant correlation between MMSE changes and baseline MMSE scores.
- The study found no correlation between vitamin B levels and cognitive decline.
- The study suggests that vitamin B supplementation may inhibit the progression of cognitive impairment in patients with vitamin B deficiency.
- Vitamin B12 deficiency among patients with dementia was found to be 4.8%.
- Low vitamin B12 levels were related to high homocysteine (HHcy) levels.
- Vitamin B12 supplementation improved HHcy levels in the short-term.
- Vitamin B12 supplementation improved the MMSE score in the short-term.
- Baseline HHcy levels were positively correlated with cognitive impairment.
- A significant correlation was found between the degree of improvement in MMSE and baseline HHcy.
- Baseline hippocampal atrophy was not associated with baseline Hcy or vitamin B12 levels.
- Inverse correlation was shown between baseline vitamin B12 and Hcy levels.
- The study had some limitations, including a small sample size and lack of a control group.
- A more systematic trial is suggested to further investigate the effects of vitamin B12 supplementation on cognitive function.
