Abstract

In the present study we evaluated cases referred as suspected Creutzfeldt-Jakob disease (CJD). Five out of 59 without prion disease showed neuropathological features of pellagra encephalopathy with widespread chromatolytic neurons (age range 40-48 years at death; one woman). These patients presentedwith a progressive neuropsychiatric disorder lasting for 2 to 24 months. Common symptoms included gait disorder, para- or tetraspasticity, extrapyramidal symptoms, incontinence, and myoclonus. Protein 14-3-3 in the cerebrospinal fluid was examined in a single patient and was positive, allowing the clinical classification as probable sporadic CJD. Pellagra encephalopathy may be considered as a differential diagnosis of CJD including detection of protein 14-3-3.
