Indeed, in elderly patients with AD, VitD deficiency is very common with an incidence of 70% to 90%. The incidence of cognitive decline is increasing rapidly due to an increase in the elderly Korean population.
Low blood concentrations of vitamin B6, vitamin B12, and folate have been found in Alzheimer's patients. Although high-dose supplementation with vitamin B6, vitamin B12, and folic acid lowers blood homocysteine concentration, it appears to have no effect on cognitive decline in Alzheimer's patients.
There's a link between vitamin D and Alzheimer's. A number of studies have shown that people with Alzheimer's have low vitamin D levels. One study found people with very low vitamin D were twice as likely to have Alzheimer's.
Several studies have been conducted to establish the link between vitamin B12 and Alzheimer's symptoms. Some associate low B12 levels with both the symptoms of Alzheimer's and actual atrophy (shrinkage) of the brain.
A new study shows that vitamin B12 may protect against Alzheimer's disease, adding more evidence to the scientific debate about whether the vitamin is effective in reducing the risk of memory loss.
Folic acid reduces homocysteine levels—high homocysteine levels put you at risk for both heart disease and memory loss. Vitamin C has been shown to reduce your risk of Alzheimer's disease by 20% when taken with vitamin E.
Vitamins E and C
They're powerful antioxidants that deliver benefits such as reduced inflammation and protection against free radicals. Research shows that people who eat a diet rich in these nutrients may have a significantly lower risk of developing Alzheimer's disease.
How to raise your B12 levels fast. The most common way to treat B12 deficiencies is by adjusting your diet. If this is unsuccessful, vitamin supplements may be recommended. If you're looking to boost the amount of vitamin B12 in your diet, you should eat more animal products, like meat, seafood, dairy and eggs.
Taking certain medications: Certain medications can cause low levels of vitamin B12 in your body, including metformin (a drug used to manage diabetes), proton pump inhibitors (PPIs are used to treat GERD and peptic ulcers), histamine H2 blockers (a medicine used to reduce the amount of acid your stomach makes) and oral ...
Low blood levels of vitamin D may increase cognitive decline in people with dementia [48,49]. The InCHIANTI study, conducted on 858 patients over 65 years of age, showed that low serum 25-hydroxyvitamin levels were associated with an increased risk of cognitive impairment.
The FDA recommends taking no more than a combined total of 3 grams of DHA or EPA a day, with no more than 2 grams from supplements. Research has also linked high intake of omega-3s to a possible reduction in risk of dementia or cognitive decline.
Several observational studies have provided evidence on the association of lower vitamin D with greater risk of AD and dementia,10 and the positive effect of vitamin D supplementation on performance on neuropsychological tests29 and risk of developing AD.
In the largest study of its kind, researchers suggests that in older people, not getting enough vitamin D may double the risk of developing dementia and Alzheimer's disease. The study is published in the August 6, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Nationwide longitudinal cohort studies also suggest long‐term vitamin D supplementation is associated with higher risk of dementia in dementia‐free older adults and higher mortality in dementia individuals. Our results caution against prolonged use of vitamin D by AD patients and older adults.
Vitamin B1, or thiamin, is crucial for the basic function of our cells and the metabolism of nutrients for energy. The brain is one of the most metabolically active organs in your body, which means it needs the support of thiamin to prevent the deficiencies that can lead to neurological problems down the line.
This study suggests that magnesium-based treatments may be useful in helping to alleviate the symptoms of age-associated memory decline.
Vitamin B12 deficiency
In older people, the first symptoms of pernicious anemia are often confusion, slowness, irritability, and apathy. Other symptoms of pernicious anemia include:Dementia could be a symptom of pernicious anemia, a rare condition caused by low levels of vitamin B12.
Bananas are a cheap, healthy, and nutrient-dense fruit that can easily become a part of every individual's diet. It is one of the best fruits rich in vitamin B12.
There are certain foods that also need a cut-down in case of vitamin B12 deficiency. “Some foods and drinks can interfere with vitamin B complex intake like alcohol, caffeine and processed foods, etc should be avoided completely,” Shah added.
Phytochemicals
Phytochemicals found in bananas help preserve nerve tissue against neurotoxins, which deteriorate nervous tissue when exposed to its substance. This may also help in preventing neurological diseases such as Alzheimer's disease.
In the CAIDE study, coffee drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia/AD by about 65% at late-life. In conclusion, coffee drinking may be associated with a decreased risk of dementia/AD.
