TSE also stands for transmissible spongiform encephalopathy. These are neurodegenerative diseases such as CJD and BSE which have been brought to public prominence in the light of the recent BSE epidemic in Britain which resulted in the ban on the export of British beef. Other human TSEs include kuru in Papua New Guinea, which is believed to be transmitted in the course of funerary rituals involving the brains of corpses; Gerstmann-Sträussler-Schenker (G.S.S.) syndrome (occurring in persons with an apparent hereditary predisposition) and fatal familial insomnia.
