ABSTRACT
A case of Creutzfeldt-Jakob disease in a 58-year-old Brazilian cattle rancher and businessman is presented. The EEG was normal, which is consistent with the fact that it was made during the first half of his illness; in a later stage suppression of normal rhythms by slow moderate voltage waves would be expected. The resemblances of kuru, scrapie and "mad cow disease" to C-J disease are discussed. In each of these 4 illnesses the patient or affected animal (scrapie and "mad cow disease") (a) has a widespread spongiform encephalopathy and consequent dementia, myoclonic epilepsy and cerebellar and corticospinal symptoms. (b) Each illness is caused by a virus (or virus-like organism called a PrP or prion) which is unusually resistant to heat and entirely resistant to ultraviolet light and x-rays. (c) This causative agent can be transmitted to other mammals by intracerebral injection or, in the proved cases of 3 of them, by the oral route. Unresolved questions about C-J disease include the following Are C-J disease, kuru, scrapie and "mad cow disease" essentially similar illnesses caused by the same virus or by subtle variants of it? What is the incubation period of C-J disease, and does its virus exist for long periods of time in some asymptomatic persons, some of whom may never become neurologically ill? How does this virus enter the bodies of most persons with C-J disease, and why does the clinical disease characteristically occur only in middle age?
