Prion Disease: What It Is, Types, Causes, Symptoms & Treatment
WebPrion disease is a group of rare, terminal neurodegenerative diseases. They happen when proteins in your brain turn into abnormal proteins known as prions. Prion disease causes brain damage that leads to dementia. Healthcare providers focus on treatments, including medication, to manage symptoms.

WebPrion Diseases. Prion diseases or transmissible spongiform encephalopathies (TSEs) are a family of rare progressive neurodegenerative disorders that affect both humans and animals. They are distinguished by long incubation periods, characteristic spongiform changes associated with neuronal loss, and a failure to induce inflammatory response.
Prion - Wikipedia
WebA prion / ˈpriːɒn / ⓘ is a misfolded protein that can induce misfolding of normal variants of the same protein and trigger cellular death. Prions cause prion diseases known as transmissible spongiform encephalopathies (TSEs) that are transmissible, fatal neurodegenerative diseases in humans and animals.

Prion diseases can affect both humans and animals and are sometimes spread to humans by infected meat products. The most common form of prion disease that affects humans is Creutzfeldt-Jakob disease (CJD). Prion diseases are rare.
