A lot of people, especially those who are young, make the mistake of taking Alzheimer’s disease for granted – that, despite it being the most common cause of dementia and the likelihood of getting the condition increases with age. Fortunately, research has revealed that B complex vitamins can significantly reduce the risk of brain disorders such as Alzheimer’s by preserving brain volume and even reversing mild cognitive decline – a symptom usually seen during the early stages of the disease.
In a study in the International Journal of Geriatric Psychiatry, researchers have established that vitamin B supplementation – in particular, vitamins B6, B9, and B12 – significantly improved the cognition and memory function of older adults that exhibited mild cognitive impairment. The authors of the study attributed it to the ability of B vitamins to reduce levels of homocysteine, an amino acid used to be a biological marker for Alzheimer’s disease.

It has a more sinister role in the body – many scientists believe that homocysteine is a pro-inflammatory substance that causes brain damage and increases the likelihood that a person will be affected by the condition. Multiple studies have shown that patients with mild cognitive impairment, a typical precursor to Alzheimer’s, have elevated levels of homocysteine in their system. It’s also responsible for problems with brain circulation since it increases oxidative stress and damages the blood-brain barriers. However, its worst (and potentially most lethal) side effect is the buildup of beta-amyloid protein in the brain – a landmark symptom for Alzheimer’s disease.(MORE)
