Creutzfeldt-Jakob disease (CJD) is the most frequent human spongiform encephalopathy. We have analyzed 53 cases of definite non familial CJD over a study period of 28 years. All were autopsied in the same neuropathological unit. Clinical and epidemiological data were in accordance with previous studies: low incidence of CJD under the age of 40, high incidence around the sixty years of age (26%) a sex ratio at 0.65 and high frequency of myoclonus, dementia and cerebellar ataxia during evolution (78%). This study highlights the rapidity at the onset of the disease (within 24 hours) in 16% of the cases. EEG disclosed typical pseudoperiodic activity in only 53% of cases and cerebral MRI showed high T2 signal intensity in basal nuclei in 15%. This regional study is the second of its nature to be carried out in France, the first one covering the area of Paris.
