[Neurological complications of inflammatory intestinal diseases].
A number of neurological symptoms have been described as complications of inflammatory bowel disorders such as coeliac disease, Whipple's disease, Crohn's disease and ulcerative colitis. The neurology of coeliac disease includes disorders of the central nervous system encompassing cerebellar ataxia, epilepsy, myoclonus, dementia and multifocal leukoencephalopathy. Peripheral neuropathies, of axonal and demyelinating types, and myopathies have also been reported. The pathomechanisms are more related to immunological-inflammatory processes than to a malresorptive vitamin deficiencies. While CNS symptoms of coeliac disease show a poor response to gluten restriction, peripheral symptoms may respond to elimination of gluten from the diet. There are few reports of a successful corticosteroid treatment in patients showing inflammatory findings in the CSF or bioptic material. Whipple's disease is caused by the gram-positive bacillus Tropheryma whipplei. Patients with a central nervous system manifestation of Whipple's disease may develop a variety of symptoms including dementia, supranuclear gaze palsy, movement disorders, hypothalamic dysfunction and myorhythmia. The CNS-infection is diagnosed by PCR of the CSF. Long-term antibiotic treatment is required, and relapses may occur after withdrawal of antimicrobial therapy. Crohn's disease and ulcerative colitis are complicated by various forms of polyneuropathies, and arterial and venous cerebrovascular diseases. In most cases with neurological complications of inflammatory gastrointestinal diseases an immune mediated inflammatory process is suspected to be the underlying pathomechanism.
