Vitamin B12 is credited for many important functions in the body and chief among them is supporting proper red blood cell formation, neurological function, and DNA synthesis. Lacking the vitamin therefore causes the body to undergo a number of unsettling changes. Some of the most serious signs of B12 deficiency are those related impaired brain function which in turn affects one’s cognitive abilities. If you are experiencing difficulties with thinking and reasoning, it could be due to a lack of B12

In another study which was published in Cureus, having low vitamin B12 levels and cognitive impairment was studied.

“Vitamin B12 deficiency is linked to impaired cognition and memory along with a sensation of tingling and numbness, an outcome of poor myelination.

“We conducted a cross-sectional, multicentre study of patients with minimal cognitive impairment (MCI) to assess for Vitamin B12 and homocysteine levels.

“All patients found to be deficient in vitamin B12 underwent replacement therapy and were assessed again after three months via the Mini-Mental State Examination (MMSE) and a review of symptoms.”

The results of the study indicated that vitamin B12 deficiency is linked to cognition, and replacement therapy may be an option to improve patient cognition outcomes. 


The treatment for vitamin B12 or folate deficiency anaemia depends on what’s causing the condition.

Anaemia is a condition in which the number of red blood cells in the blood, or the amount of haemoglobin in them, is lower than normal, causing a condition in which red blood cells are not able to supply enough oxygen to all the tissues in the body.

There are two types of vitamin B12 injections:
