Vitamin B12 Deficiency: The problem of forgetfulness and slowing down of thinking is often considered to be the effect of age, stress or work pressure, but sometimes the real reason for this is the deficiency of Vitamin B12. This nutrient, which is essential for the health of the brain and nerves, is found in less quantity especially in the elderly, vegetarian people and patients suffering from some medical conditions. If it is identified in time, then major problems like weakening of memory and reduced thinking ability can be avoided.
Scientific studies have consistently revealed that along with age or stress, lack of nutrition also affects the functioning of the brain. Among these, most attention is being given to the deficiency of Vitamin B12. It is a water-soluble vitamin, which we mostly get from meat, fish, eggs and dairy products. It helps in protecting the brain cells, transmitting nerve signals properly and controlling the level of homocysteine in the body. When there is a deficiency of B12 in the body, all these processes get disturbed and as a result problems like weak memory, taking time to think and reduced concentration increase.
How does Vitamin B12 affect the brain?
Vitamin B12 supports the brain and nervous system in many ways. One of its active forms, methylcobalamin, helps convert homocysteine into methionine in the body. This process is important in making DNA and preparing neurotransmitters. When B12 is low, homocysteine starts increasing, causing further damage to brain cells. This affects memory, learning ability and attention. Many studies suggest that increased homocysteine can cause changes in the hippocampus and prefrontal cortex, which are parts of the brain that handle memory and thinking.
Adenosylcobalamin, another form of vitamin B12, is involved in energy production and the myelin sheath, which is the layer that protects nerves. Helps in keeping it strong. Due to its deficiency, the signals in the nerves become slow, due to which forgetfulness, lack of attention and decline in thinking ability are seen. In many cases, if deficiency persists for a long time, the risk of dementia may also increase.
Who are most affected by B12 deficiency?
- The amount of stomach acid often decreases in the elderly, due to which B12 from food is not absorbed properly.
- Vegetarians and vegans are also at risk because B12 is not naturally present in plants.
- Digestive system problems, such as celiac, Crohn’s disease, pernicious anemia or intestinal surgery, also affect absorption.
- B12 levels can also decrease if metformin or acidity medicines are taken for a long time.
- Diabetes, kidney problems and environmental factors like pollution also increase the risk.
That is, B12 deficiency often occurs not due to a single reason, but due to a combination of many reasons.
How to recognize early signs of B12 deficiency?
In the beginning, very mild symptoms are seen, such as forgetting things, not being able to concentrate, slowing down thinking or difficulty in solving problems. Along with this, there may also be changes in mood like irritability, sadness or anxiety.
How to prevent it?
Eat a diet rich in B12. It is found in abundance in meat, fish, eggs and dairy. Vegetarian people should take fortified food or supplements.
If needed, take supplements, it can be taken in any form, pill, drop or injection.
It is necessary to get the risk group tested, the elderly, patients with digestive diseases and people taking medicines for a long time should get tested from time to time.
