Sažetak
Limited potential of electroencephalogram (EEG), magnetic resonance images (MRI) and cerebrospinal fluid (CSF) test for 14-3-3 protein in the clinical diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) resulted in developments in diagnostic premortem tehniques. Recent studies provided evidence that magnetic resonance spectroscopy (MRS) and measurement of total-tau (T-tau) and phospho-tau (P-tau) may be useful to identify patients with CJD. We combined detected metabolic changes in the brain by MRS and measured T-tau and tau-pT181 by ELISA, and tau-pT231 by Westernblot in a patient with autopsy proven sCJD. Our results show that in contrast to negative CSF 14-3-3 protein, nonspecific EEG and MRI, MRS revealed metabolic alterations in regions of the brain that has appeared normal on MRI, and tau tests has shown measurable levels of phosphorylated and non-phosphorylated isoforms in CSF We conclude that rapidly progressive dementia with negative 14-3-3 test and non-specific initial EEG and MRI must still be considered in the differential diagnosis of the sCJD. Combination of serial functional MRI along with MRS study and measurement of tau ratio could improve the early diagnosis of sCJD. The current case is the first attempt to study results of the use of MRS and tau tests in a case of sCJD with diagnostic dilemma.
