Depression is a possible manifestation of vitamin B12 deficiency and may be accompanied by anemia or dementia.
Stroke is a medical condition characterized by interruption of blood flow to the brain, causing a physical or mental handicap. Vitamin B12 deficiencey may increase the risk of stroke among young people who are not otherwise at risk of stroke. Whether or not there is a link is highly controversial, and the risk may result from excess homocysteine levels.
Myelopathy means disease of the spinal cord. Vitamin B12 deficiency causes a type of spine disease called subacute combined degeneration of the spinal cord, which is loss of the protective myelin of certain areas of the spinal cord that control moment, balance and sensation.
Symptoms of subacute combined degeneration of the spinal cord include:
Weakness
Numbness, tingling
Spasticity
Balance problems
Tongue swelling also results from vitamin B12 deficiency. Glossitis is the name used to describe a painful, unusually smooth tongue that can result from this nutritional deficiency.
Associated Conditions
Thyroid disease and multiple sclerosis (MS) are both conditions believed to be related to an autoimmune process. An autoimmune disease is a condition caused by the body attacking itself.
Intrinsic factor deficiency is an autoimmune disease that results from a ‘self’ attack on the region of the stomach that is involved in vitamin B12 absorption. Often, individuals who have thyroid disease or MS also have intrinsic factor deficiency and its associated vitamin B12 deficiency.
