Alzheimer’s and prion diseases belong to a category of conformational neu-rodegenerative disorders [Prusiner SB (2001)N Eng J Med344, 1516–1526; Sadowski M & Wisniewski T (2007) Curr Pharm Des13, 1943–1954; Beekes M (2007)FEBS J274, 575]. Treatments capable of arresting or at least effectively modifying the course of disease do not yet exist for either one of these diseases. | MINIREVIEW Therapeutic approaches for prion and Alzheimer s diseases Thomas Wisniewski1 2 3 and Einar M.

Alzheimer s disease is the major cause of dementia in the elderly and has become an ever greater problem with the aging of Western societies. Unlike Alzheimer s disease prion diseases are relatively rare. Each year only approximately 300 people in the USA and approximately 100 people in the UK succumb to various forms of prion diseases Beekes M 2007 FEBS J 274 575 Sigurdsson EM Wisniewski T 2005 Exp Rev Vaccines 4 607-610 . Nevertheless these disorders have received great scientific and public interest due to the fact that they can be transmissible among humans and in certain conditions from animals to humans. The emergence of variant Creutzfeld-Jakob disease demonstrated the transmissibility of the bovine spongiform encephalopathy to humans Beekes M 2007 FEBS J 274 575 . Therefore the spread of bovine spongiform encephalopathy across Europe and the
