[New investigations in suspected Creutzfeldt-Jakob disease. Analysis of 14-3-3 protein and T-tau in cerebrospinal fluid for safer diagnosis].

Creutzfeldt-Jakob disease (CJD) is a prion disease characterized by rapid neurodegeneration that leads to the death of the patient within months to a few years. Since the disease is transmissible, there is an obligation in Sweden to report possible CJD cases to the Swedish Institute for Infectious Disease Control. To make a diagnosis of CJD is difficult, especially early in the course of the disease when the clinical features may be very vague and heterogeneous.
