Background: Recent preventive strategies for patients with cognitive impairment include the identification of modifiable somatic risk factors like vitamin D deficiency. Methods: A systematic literature research and meta-analysis were conducted to assess the association of cognitive impairment and vitamin D deficiency. Results: Data from cross-sectional and longitudinal studies suggest an association between cognitive impairment and vitamin D deficiency. Meta-analysis of 5 cross-sectional and 2…

Vitamin D deficiency is associated with increased risk of Alzheimer’s disease and dementia: evidence from meta-analysis
It is indicated that lower vitamin D status may be associated with increased risk of developing AD and dementia and more studies are needed to further confirm the associations and to evaluate the beneficial effects of vitamin D supplementation in preventingAD and dementia.
Vitamin D and Dementia.
There is a need for large double-blind randomised-control trials investigating whether vitamin D supplementation can halt or delay the risk of dementia-related outcomes in individuals with low vitamin D concentrations.
Quality assessment of systematic reviews of vitamin D, cognition and dementia
This systematic evaluation of available systematic reviews provided a clearer understanding of the potential link between low serum vitamin D concentrations and dementia and showed that the quality of the available evidence is not optimal because of both the low methodologicalquality of the reviews and low quality ofThe original studies.
Vitamin D Supplement for Prevention of Alzheimer's Disease: A Systematic Review and Meta-Analysis
Overall, the current evidence did not support the beneficial effect of VD supplement to prevent AD and high quality RCTs and further studies are needed to clarify the effects of V D supplementation on preventing AD.

It appears crucial to maintain vitamin D concentrations at sufficiently high levels in order to slow, prevent, or improve neurocognitive decline.
Vitamin D deficiency is associated with neurocognitive impairment in HIV-infected subjects
In HIV-positive persons, severe hypovitaminosis D was independently associated with a higher risk of neurocognitive impairment in general, and of HIV-associated neuroc cognitive disorders in particular.
The Correlation between Vitamin D and Cognition: A Review
Accumulating evidence in the current literature indicate that vitamin D deficiency is highly prevalent among patients with cognitive impairment, and that low vitamin D status may negatively impact cognition and that hypovitaminosis D is usually associated with increased risk of developing AD and dementia.
Effect of vitamin intake on cognitive decline in older adults: Evaluation of the evidence
Evaluation of the totality of the currently available evidence indicates that intake of the above vitamins, either as a monotherapy, or in combination with other vitamins, has no clinically-relevant effect on delaying cognitive decline or delaying the onset of dementia in older adults.

This first follow-up study of elderly people, including the oldest-old, in Asia shows that low vitamin D levels were associated with increased risk of subsequent cognitive decline and impairment.


Vitamin D and cognitive impairment in the elderly U.S. population.
Findings suggest that vitamin D deficiency is associated with increased odds of cognitive impairment in the elderly U.S. population and further exploration of a possible causal relationship between Vitamin D deficiency and cognitive impairment is warranted.
Vitamin D, Cognitive Dysfunction and Dementia in Older Adults
No large randomized controlled trials have yet examined the effect of vitamin D supplements on cognitive decline or incident dementia, and no prospective studies have examined the association between 25(OH)D levels and incident dementia or neuroimaging abnormalities.
Vitamin D deficiency is associated with low mood and worse cognitive performance in older adults.
In a cross-section of older adults, vitamin D deficiency was associated with low mood and with impairment on two of four measures of cognitive performance.
Serum Vitamin D Deficiency as a Predictor of Incident Non-Alzheimer Dementias: A 7-Year Longitudinal Study
Baseline vitamin D deficiency predicted the onset of NAD within 7 years among older women and was associated with Alzheimer’s disease, whereas Vitamin D deficiency was not associated with AD.
Vitamin D and risk of cognitive decline in elderly persons.
Low levels of vitamin D were associated with substantial cognitive decline in the elderly population studied over a 6-year period, which raises important new possibilities for treatment and prevention.
Serum 25-Hydroxyvitamin D Concentration and Cognitive Impairment
The data suggest low serum 25-hydroxyvitamin D is associated with increased odds of cognitive impairment, and this work suggests vitamin D may be of interest in the prevention of Cognitive impairment.
Higher Serum Vitamin D3 Levels Are Associated with Better Cognitive Test Performance in Patients with Alzheimer’s Disease
The data support the idea that a relationship exists between vitamin D status and cognition in patients with probable AD, but given the cross-sectional design of this study, no causality can be concluded.
Does vitamin D reduce the risk of dementia?

The hypothesis that vitamin D can reduce the risk of developing dementia is developed, presenting the evidence from observational and laboratory studies and indicating there do not appear to be observational studies of incidence of dementia with respect to prediagnostic serum 25(OH)D or vitamin D supplementation.
