The importance of homocysteine for preserving cognitive function
One of the functions of this vitamin is to prevent the accumulation of homocysteine, a toxic substance produced by the metabolism. It could harm the brain when the body doesn’t properly eliminate it.
Homocysteine is a metabolic waste product produced in the body. It doesn’t normally wreak havoc, as there are systems in place to eliminate it.
However, failure to eliminate this substance can lead to blockage of the blood vessel walls. This reduction of the ducts hinders the circulation of blood throughout the body, including the brain. Moreover, the accumulation of homocysteine can damage neurons.
Vitamins B6, B9, and B12 can eliminate this residue. In fact, their action is so important that any deficiencies increase the risk of neurodegenerative diseases such as Alzheimer’s and dementia, according to research published in the journal Advances in Nutrition.

Preventing deficiencies to preserve cognitive function
In recent years, scientific research found that levels of B vitamins are lower in people with neurodegenerative diseases. Noted that this is also related to their age.
Also, a recently published international consensus concludes that elevated homocysteine levels in the blood (between 5-30 % more than normal) are a risk for cognitive impairment and dementia in older people.
This is why you can simply correct a B-vitamin deficiency: add a variety of food that’s rich in vitamin B to your regular diet.
Vitamin B is present in many types of food such as meat, fish, and green leafy vegetables. Thus, it isn’t difficult to obtain them and correct (or avoid, as the case may be) any deficiencies you might have.

Vitamin B9 is present in green leafy vegetables and herbs such as broccoli, spinach, lettuce, chard, parsley, watercress, etc. as well as avocado, papaya, oranges, legumes, and nuts.
Its deficiency can cause headaches, irritability, mood swings, weakness, and lack of concentration.
Vitamin B12 is particularly abundant in meat, fish, seafood, eggs, and dairy products, so vegans are more prone to this kind of deficiency.
