INVESTIGATIONS: Neurological examination, neurophysiological studies, brain MRI scan, routine blood tests, duodenal biopsy, cerebrospinal fluid analysis including polymerase chain reaction test for JC virus DNA, serological testing for HIV and for the presence of serum antibodies to endomysium, gliadin and tissue transglutaminase.

DIAGNOSIS: Celiac disease with neurological involvement, mimicking amyotrophic lateral sclerosis.
