B12 for red cells: Many people are B12 deficient. It's an important nutrient in red blood cell and nerve development. Symptoms of deficiency include: weakness, fast heart beat, pale skin, easy bruising, tingling or numbness in fingers and toes, difficulty walking, depression, memory loss and dementia. A significant factor in causes of this deficiency is the use of acid-reducing drugs for gerd.

Yes.: Pernicious anemia is the most common reason for unexpected B12 deficiency. Lack of B12 can cause both anemia and neurological damage. The latter includes numbness, gait problems, and dementia. Anemia causes weakness. The neurological findings can occur before there is any anemia, or vice versa. The anemia will reverse with treatment. Neurologic changes may not correct.

Vit B 12 Deficiency: Lack of Vit B 12 can lead to Hypocobalaminemia. This can cause a slow degration of the spinal cord & brain. Problems may include: swollen tongue, anemia, sense of numbness & tingling in extremities, weakness, fatigue, problems walking, jaundice, depression, irritability, memory decline, cognitive dulling & eventually mania &/or psychosis.

A 46-year-old member asked:

Why does vitamin B12 deficiency cause neurological symptoms?

2 doctor answers4 doctors weighed in
Dr. James Ferguson
Pediatrics 46 years experience
Required by nerves: This co-factor is needed by the nerves to stay healthy. Each nerve cell has a self repair system that relies on a variety of nutrients in our diet to provide the needed material to keep the walls intact and the cell working. Lack of B12 eventually causes that repair system to start breaking down and nerve cells malfunction or degenerate, leading to neurologic symptoms.

Not at all likely: Almost no chance of a direct link, but... We do know that: 1) the b vitamins are important to nervous system functioning. 2) B12 can make a noticeable difference in how good one feels. 3) deficiencies are (by definition) good to correct. So, do try to improve your diet and even supplement nutrients that are hard to get enough of. See a professional for ocd treatment too.

Not Always: The progression of neurologic complications is generally gradual. They are not always reversible with treatment of vitamin B12 deficiency, especially if they have been present for a long time.
