Summary
Accurate diagnosis of prion diseases, fatal neurodegenerative disorders, is crucial. New methods like real-time quaking-induced conversion (RT-QuIC) improve early detection, aiding patient management and preventing transmission.
Area of Science:
- Neurology
- Biochemistry
- Pathology
Background:
- Prion diseases are fatal neurodegenerative disorders caused by misfolded prion proteins.
- Early and accurate diagnosis is critical to differentiate prion diseases from treatable dementias and prevent iatrogenic spread.
Purpose of the Study:
- To review advancements in antemortem diagnostic capabilities for prion diseases.
- To highlight the role of new biomarkers and techniques in improving early detection.
Main Methods:
- Review of current diagnostic approaches including clinical evaluation, neuroimaging, electroencephalography, and cerebrospinal fluid biomarkers.
- Emphasis on the development and application of real-time quaking-induced conversion (RT-QuIC) assay for prion protein detection.
Main Results:
- Antemortem diagnostic capabilities have significantly improved beyond traditional postmortem neuropathology.
- Real-time quaking-induced conversion (RT-QuIC) demonstrates high specificity in detecting misfolded prion proteins, complementing existing methods.
Conclusions:
- Despite advancements, challenges in early identification and disease management persist.
- Continued research is vital for enhancing prion disease diagnosis, tracking progression, and understanding pathogenesis.

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
