The insomnia phenotype in genetic Creutzfeldt-Jakob disease based on the E200K mutation.
The aim of the presented study was to reveal the frequency of insomnia spells in E200K genetic Creutzfeldt-Jakob disease (gCJD) patients. Clinical records of 22 subjects diagnosed with E200K gCJD were retrospectively reviewed. The patients w/wo insomnia (n = 4, 18%/n = 18, 82%) did not differ in age, sex and the duration of the symptomatic phase. Analysis of the clinical features in the groups yielded differences in the clinical signs in the early phase of the disorder, proportion of homozygotes (Met/Met) at codon 129, MRI changes in the thalamus and the typical EEG abnormality. The study suggests that apart from traditional clinical features, the insomnia is not a rare early symptom in phenotype of E200K gCJD based on early thalamic involvement.
期刊介绍：
Prion is the first international peer-reviewed open access journal to focus exclusively on protein folding and misfolding, protein assembly disorders, protein-based and structural inheritance. The goal is to foster communication and rapid exchange of information through timely publication of important results using traditional as well as electronic formats. The overriding criteria for publication in Prion are originality, scientific merit and general interest.
