Studies of TSEs, BSE, CJD and prion protein

Studies of transmissible spongiform encephalopathies (TSEs) (including Bovine Spongiform Encephalopathy, BSE, and Creutzfeldt-Jakob Disease, CJD) and prion protein should always be coded as Neurological - even when a study is investigating transmission or mechanism of disease it should not be coded as Infection.
