All prion diseases are inevitably fatal; there are no known cures.
Secondary structure of prion proteins in prion disease like Creutz feldt-Jakob disease (CJD) is
A prion, or misfolded protein caused by genetic mutation.
Amyotrophic lateral sclerosis (ALS) is primarily classified as a neurodegenerative disease rather than a prion disease. While prion diseases are caused by misfolded proteins that induce abnormal folding in other proteins, ALS is associated with the aggregation of proteins like TDP-43 and SOD1, but it does not exhibit the specific transmissible properties characteristic of prion diseases. Some research suggests similarities in protein misfolding mechanisms, but ALS does not meet the criteria to be classified as a prion disease.
Sporadic prion diseases occur spontaneously without a known cause. It is believed to be caused by the misfolding of normal cellular prion proteins into infectious, disease-causing forms. The risk factors for sporadic prion diseases are not well understood, and there is currently no definitive way to prevent or predict their occurrence.
Yes, prions can interact with and convert other normal proteins into misfolded prion proteins, propagating the disease process. This conversion leads to the accumulation of abnormal prions in the brain, causing neurodegenerative diseases such as Creutzfeldt-Jakob disease.

There are multiple prion diseases, including bovine spongiform encephalopathy (BSE), or "mad cow disease."

NO. It is caused by a PRION, not a virus.

Extremely rare. Bovine spongiform encephalopathy (BSE, the scientific name for mad cow disease) is caused by an infectious misfolded protein called a prion. This prion has been all but eradicated from the world and human cases of variant Creutzfeld-Jacobs Disease (vCJD, the name of the disease in humans caused by the BSE prion) have fallen to almost none.
Gerstmann-Sträussler-Scheinker disease (GSS) is a hereditary form of prion disease caused by mutations in the PRNP gene. It is characterized by progressive neurodegeneration, ataxia, and dementia. Symptoms typically manifest in adulthood.
