Rapidly progressive form of Creutzfeldt-Jakob disease without dementia: a case report

We describe a case of a patient with Creutzfeldt-Jakob disease (CJD) characterized by a rapid clinical course lasting one and a half months, by: presence of focal dystonic movements at onset, absence of mental deterioration in the period preceding the impairment of consciousness, ataxia, myoclonus and periodic EEG abnormalities. The autopsy confirmed subacute spongiform encephalopathy, but no evident neuronal loss was observed. An acute clinical course of CJD may explain this latter histological finding which, in turn, probably provides an explanation for the absence of intellectual impairment.
