Gluten ataxia is an autoimmune disorder, caused by the reaction to protein gluten. In people with gluten ataxia, the antibodies respond to the ingestion of gluten by mistakenly attacking the cerebellum which is the part of brain responsible for motor control, balance and muscle tone.
Our own white blood cells, normally in charge of protecting us from diseases, attack the cerebellum, incited by gluten. If left untreated, the disease progresses slowly, resulting in serious problems in balance and motor control, caused by irreversible brain damage. (1)
