Rapidly Progressive Probable Sporadic Creutzfeldt-Jakob Disease.

Creutzfeldt-Jakob disease (CJD) is a rare, fatal brain infection caused by a human prion. Because CJD is associated with rapidly progressive neurological degeneration, it requires high suspicion for diagnosis. We report the case of a 79-year-old patient who presented with a rapidly progressive neurological clinical picture. The patient had positive 14-3-3 proteins in cerebrospinal fluid, electroencephalography was significant for periodic discharges, and magnetic resonance imaging of the brain showed both diffusion restriction and increased fluid-attenuated inversion recovery signal in different cortical regions, consistent with probable sporadic CJD infection. The patient was enrolled under hospice and palliative care. The patient passed away two months after the onset of her symptoms. We discuss the probable sporadic CJD diagnostic criteria and possible risk factors that might have led to a faster progressive course.
