Vitamin B12, Homocysteine, and Cognitive Function in the Older Adults Attending Tertiary Geriatric Psychiatry Centre: A Retrospective Case Notes Based Study
Retrospective study finds no significant links between vitamin b12, homocysteine levels, and cognitive function in older adults with various disorders.
Key Points
No significant independent associations exist between vitamin b12 or homocysteine levels and cognitive test scores.
About 72% of older adults had elevated homocysteine levels, while 33% had low vitamin b12 levels.
The multi-linear regression highlighted gender's role in cognitive assessment scores, overshadowing other measured variables.
Findings suggest that vitamin b12 and homocysteine may not be primary predictors of cognitive impairment in older adults.
