This finding can be the basis of a hypothesis that chronic, very low levels of vitamin B12 could be the cause of permanent, or at least refractory, changes in cognition and memory, which can lead to dementia.
Low vitamin D levels were linked with an increased risk of both dementia and stroke over the following 11 years. Based on this observational study, people with low vitamin D levels were found to have a 54% greater chance of developing dementia compared with people whose levels were normal.
Vitamins E and C
For those in the early stages of dementia, supplementing with vitamin E on a daily basis has been shown to slow the progression of the disease, while daily supplementation of 400 to 800 IU per day of vitamin E may help to protect older adults from developing dementia.
Abstract. Vitamin B12 deficiency is a cause of reversible dementia that must be ruled out in the evaluation of neurocognitive decline.
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.

Deficiency of Vitamin B12 can result in hematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss [9].
Neurological changes. A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as: vision problems. memory loss.
Magnesium threonate may help boost circulating magnesium levels. As it effectively raises magnesium levels in brain cells, it could reduce an individual's risk of dementia and other age-related diseases.
Best Foods for Preventing Dementia
Food that are rich in carotenoids include carrots, squash, sweet potatoes, bell peppers, tomatoes, papaya, apricots, and leafy greens such as spinach and kale.
Alzheimer's disease accounts for 60-80% of cases. Vascular dementia, which occurs because of microscopic bleeding and blood vessel blockage in the brain, is the second most common cause of dementia. Those who experience the brain changes of multiple types of dementia simultaneously have mixed dementia.
The World Health Organization (WHO) identifies pregnant and lactating women as among the groups at greatest risk of vitamin B12 deficiency [22].
Long-term vitamin B12 deficiency can cause nerve damage. This may be permanent if you do not start treatment within 6 months of when your symptoms begin. Vitamin B12 deficiency anemia most often responds well to treatment. It will likely get better when the underlying cause of the deficiency is treated.
