[Neurological complications of inflammatory bowel diseases].

Inflammatory bowel diseases, such as Crohn's disease, ulcerative colitis, autoantibody driven celiac disease and infectious Whipple's disease can all be associated with neurological symptoms. The neurological manifestation may occur even before the gastrointestinal symptoms or the enteropathic symptoms can even be absent as in celiac disease. These diseases can be caused by malresorption and lack of vitamins due to enteral inflammation as well as (auto-)immunological mechanisms and drug-associated side effects. Thus, inflammatory bowel diseases have to be considered in the differential diagnosis. In this review the most common neurological manifestations of these diseases will be described as well as the diagnostic approach.
