We describe 10 neuropathologically verified patients with Creutzfeldt-Jakob disease who died in Argentina between 1980 and 1987. Two of the ten cases were Chilean by birth. Another case visited Chile several times. Two cases (one Argentinian and one Chilean) regularly consumed sheep brain. Ages ranged from 42 to 63 years and the male to female ratio was 7:3. Disease duration ranged from 3.5 to 24 months. Prodromal symptoms presented as behavioral changes in 5 patients, lasting from one year to several weeks, and as neurological impairment in the other 5. Patients developed pyramidal, extrapyramidal and cerebellar disturbances, as well as movement disorders and progressive dementia. Visual alterations were found in 5 cases and periodic EEG activity in 7. Unequivocal cortical spongiform changes, together with varying degrees of neuronal depletion and astroglial hyperplasia were constant findings. No white matter involvement was apparent either from CT brain scans or on histopathological study of biopsied and autopsied material. Increasing awareness of this disease as well as possibilities of transmission is necessary in order to provide better information on its true incidence in Argentina.
