Genomic and Nongenomic Signaling Induced by 1a,25(OH)2-Vitamin D3 Promotes the Recovery of Amyloid-ß Phagocytosis by Alzheimer’s Disease Macrophages
2012 research published Journal of Alzheimer's Disease indicated that vitamin D3 may support brain functioning by activating certain genes and cell signaling networks to strengthen up the immune system to help get rid of amyloid plaque.

Study funding included the Alzheimer's Association and NIH.

Is vitamin D important for preserving cognition? A positive correlation of serum 25-hydroxyvitamin D concentration with cognitive function
This study analyzed the relationship of vitamin D with cognitive functioning and the possible mechanisms. It describes the analysis of older adults at a university medical clinic who received consultating assessments for memory problems.

The researchers determined that a significant, positive relationship existed between patients' concentrations of blood serum 25(OH)D and the mini-mental state examination score (MMSE) - suggesting a possible role for vitamin D in cognitive functioning.

Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men
Researchers examined the connection between levels of 25-hydroxyvitamin D (25(OH)D) and cognitive functioning in33,369 older and middle-aged European men aged 40–79 years. Their cognitive function was measured using the Rey–Osterrieth Complex Figure test, the Camden Topographical Recognition Memory test and the DSST (Digit Symbol Substitution Test). The scientists found relationships between cognitive functioning capacity and 25(OH)D levels by way of locally weighted and linear regression models.

They found lower 25(OH)D levels were connected to poorer performance on the DSST.

Macular Degeneration

Vitamin D and Reduced Risk of Macular Degeneration: 2011 Study
Researchers looked at blood level data of vitamin D among 1,313 women 50 to 79 enrolled in the ongoing Women's Health Initiative study. They found that in those women who were younger than 75, vitamin D from foods and supplements (but not from time spent in direct sunlight) was linked with decreased risk of developing early age-related macular degeneration. Those who consumed the most vitamin D had a 59 percent decreased risk of developing AMD compared with women who consumed the least.

Low Levels of Vitamin D3 tied to macular degeneration: 2007 Study
Researchers in this study found that low levels of vitamin D3 in the body are connected to an increase in the presence of macular degeneration. Consumption of milk, fish, and vitamin D supplements were assessed. Lower consumption of milk had more risk of early macular degeneration. Patients who consumed less fish had more risk of advanced macular degeneration. Patients who did not drink milk but who took vitamin D supplements had less risk of early macular degeneration.

The researchers concluded that vitamin D likely helps prevent against macular degeneration but that more investigation is needed to verify these results in the future.
