In Australia, the occurrence of all human transmissible spongiform encephalopathies (TSEs) is surveyed by the Australian National Creutzfeldt-Jakob Disease Registry (ANCJDR). While prospective surveillance commenced in October 1993, the ANCJDR also retrospectively ascertained cases that occurred between 1970 and 1993. During the surveillance period of 1 April 2008 to 31 March 2009, the ANCJDR received 90 suspect TSE case notifications, which is slightly increased from previous annual surveillance periods. Based on the total number of probable and definite CJD cases, ascertained between 1993 and 2009, the Australian age-adjusted mortality rate is 1.18 deaths per million per year. In this short report, we provide updated Australian human TSE figures and discuss a recently published investigation of geographical TSE clustering in regional New South Wales.

The three-dimensional structure of proteins, achieved through the folding of the nascent polypeptide chain in vivo, is largely facilitated by molecular chaperones, which are crucial for determining protein functionality. In addition to aiding in the folding process, chaperones target misfolded proteins for degradation, acting as a quality control system within the cell. Defective protein folding has been implicated in a wide range of clinical conditions, including neurodegenerative and metabolic disorders.

Creutzfeldt-Jakob Disease (CJD) is an exceedingly rare condition with an incidence of one case per million people worldwide. It is diagnosed with symptoms of rapid neurological decline, positive CSF biomarkers, and diagnostic findings on MRI and EEG. There is no known effective therapy for CJD and prompt diagnosis is required to prepare for the expected disease prognosis and goals of care discussions.

Prions are assemblies of misfolded prion protein that cause several fatal and transmissible neurodegenerative diseases, with the most common phenotype in humans being sporadic Creutzfeldt-Jakob disease (sCJD). Aside from variation of the prion protein itself, molecular risk factors are not well understood. Prion and prion-like mechanisms are thought to underpin common neurodegenerative disorders meaning that the elucidation of mechanisms could have broad relevance.

Alzheimer's disease (AD) is characterised by progressive neurodegeneration with the formation of amyloid beta (Aβ) plaques and neurofibrillary tau tangles in the brain parenchyma. The causes of AD have been attributed to a combination of age-related changes within the brain as well as genetic, environmental and lifestyle factors. However, a recent study by Banerjee et al.

Prion diseases, including Creutzfeldt-Jakob disease (CJD), are deadly neurodegenerative disorders characterized by the buildup of abnormal prion proteins in the brain. This accumulation disrupts neuronal functions, leading to the rapid onset of psychiatric symptoms, ataxia, and cognitive decline. The urgency of timely diagnosis for effective treatment necessitates the identification of strongly correlated biomarkers in bodily fluids, which makes our research crucial.
