Sporadic Creutzfeldt-Jakob disease in older people
Published online by Cambridge University Press: 11 December 2009
Summary
Prion diseases are rare degenerative disorders of the nervous system caused by abnormal accumulation and/or metabolism of prion proteins. They are invariably fatal. Creutzfeldt-Jakob disease (CJD) is the most common human prion disease and the sporadic form accounts for 85% of cases, whilst about 15% are genetic and 1% is iatrogenic. Variant CJD (vCJD) was mostly seen in the UK and France and mainly affected young people. Sporadic CJD (sCJD) occurs throughout the world with mean age of onset in the seventh decade. It typically presents with rapidly declining cognition that may get confused with other forms of dementia. Thus identification of sCJD in older people depends on a judicious awareness of the clinical features. Here we present a clinical, pathological, therapeutic and diagnostic review of sCJD.
