Deafness: an unusual onset of genetic Creutzfeldt-Jakob disease

We describe a case of genetic Creutzfeldt-Jakob disease (CJD) with deafness at the onset. We report clinical features, 14-3-3 protein positivity, electroencephalography and brain stem auditory evoked potential abnormalities, and high signal on magnetic resonance imaging in basal ganglia and temporal cortex. Similarities with CJD Heidenhain variant are discussed.
