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.
