Abstract

Background: Creutzfeldt-Jacob disease (CJD) is a fatal neuro-degenerative disease, characterized by rapid and intense deterioration, mainly cognitive, leading to death. The typical onset of the disease is around the age of 67. Purpose: To characterize the demographic and clinical features of the population of CJD patients with late-onset disease. Methods: In this retrospective study, the Israeli national database of prion diseases was screened for CJD patients with disease age of onset > 80 years between 1960 and 2016. Patient’s demographic and clinical data were collected including sex, type of disease (sporadic/ genetic), clinical presentation, lab results including tau protein level, imaging, and EEG characteristics. Then, the clinical and demographic data of patients with late onset (> 80 years) (L) and patients with usual age of onset (< 80 years) (U) were compared. Results: The study included 728 patients, 23 patients (3.3%) with late-onset disease (82.2.4±4 years, range 80–88) and 705 with usual disease onset (61.31 ± 9.47 years, range 34–80). Sporadic CJD was more common in the late-onset group (18/23 patients (78.2%) (L) vs. 256/705 patients (36.3%) (U)) (p = 0.0001, chi-square test). Classical EEG finding of periodic sharp wave activity were seen more often in the late-onset patients (55% (L) vs. 32.5% (U)) (p = 0.05, chi-square test). The rest of the demographic and clinical features were similar in both groups. Conclusion: Late- and usual-onset diseases are similar in most of demographic and clinical features suggesting a common disease type with normal distribution of age of onset.
