Deans' stroke musings: Associations of folate/folic acid supplementation alone and in combination with other B vitamins on dementia risk and brain structure: evidence from 466,224 UK Biobank participants

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Associations of folate/folic acid supplementation alone and in combination with other B vitamins on dementia risk and brain structure: evidence from 466,224 UK Biobank participants

FYI.

Folate or folic acid supplementation was tied to a higher risk of Alzheimer's disease and changes in brain structure, but the effects were counteracted when other B vitamins were added. (The Journals of Gerontology: Series A)

Associations of folate/folic acid supplementation alone and in combination with other B vitamins on dementia risk and brain structure: evidence from 466,224 UK Biobank participants

Author Notes

Abstract

Previous researchers have tried to explore the association between folate/folic acid intake and dementia incidence, but the results remain controversial. We evaluated the associations of folate/folic acid supplementation alone and in combination with other B vitamins on dementia risk and brain structure. A total of 466,224 UK Biobank participants were investigated. Cox proportional hazards models were used to assess the associations between folate/folic acid supplementation status and the risk of Alzheimer's disease (AD) and vascular dementia (VD). Multivariable linear regression models were employed to evaluate the association between folate/folic acid supplementation status and brain structure. In the final model, folate/folic acid supplementation alone was significantly associated with a higher risk of AD (hazard ratio [HR] =1.34, 95% confidence interval [CI] =1.06 to 1.69, p=0.015) and VD (HR=1.61, 95% CI=1.21 to 2.13, p=0.001). Folate/folic acid supplementation alone was associated with a reduction in the hippocampus (β= -95.25 mm³, 95% CI= -165.31 to -25.19 mm³, p=0.014) and amygdala (β= -51.85 mm³, 95% CI= -88.02 to -15.68 mm³, p=0.012). The risk of AD and VD, as well as brain structure, in the group with combined folate/folic acid supplementation and other B vitamins did not show a statistically significant difference compared to the reference group (all p>0.05). Folate/folic acid supplementation alone is significantly associated with a higher risk of AD and VD, as well as adverse alterations in brain structure. However, when combined with other B vitamins, these detrimental effects can be counteracted.
