To report the clinical, neuropsychological, linguistic, imaging, and neuropathological features of a unique case of sporadic Jakob-Creutzfeldt disease in which the patient presented with a logopenic variant of primary progressive aphasia.

Design Case report.

Large referral center for atypical memory and aging disorders, particularly Jakob-Creutzfeldt disease.

Patient presenting with logopenic variant primary progressive aphasia initially thought to be due to Alzheimer disease.

Despite the long, slow 3.5-year course, the patient was shown to have pathology-proven sporadic Jakob-Creutzfeldt disease.

These findings expand the differential of primary progressive aphasia to include prion disease.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.
