Can having vitamin b12 deficiency cause ocd 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.

Can a vitamin B12 deficiency bring around ocd?

Amazingly, yes: Hermesh et al published in 1988 about 20% of an ocd group having unusually low levels of b12. http://www.ncbi.nlm.nih.gov/pubmed/3176999 there was another report by sharma & biswas, 2012 - a cae of a middle-aged man with ocd, low serum b12, and a + family hx of B12 deficiency who responded to B12 replacement. I would definitely get that level, as well as a methylmalonic acid level, checked.

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.

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.

A 19-year-old male asked:

Are the neurological symptoms from vitamin B12 deficiency reversible?

Dr. Lori Semel

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.
