A 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.
Jan 21, 2024 · Prion disease (sometimes called transmissible spongiform encephalopathy) causes brain damage that leads to dementia. These symptoms develop suddenly and worsen quickly. It’s rare, affecting about 1 in 1 million people worldwide. Prion diseases are terminal illnesses.
Apr 22, 2024 · Prion diseases occur when proteins normally in the body misfold and cause illness. The misfolding leads to brain damage and other symptoms. Symptoms may take years to develop. But once they do, the disease rapidly progresses and leads to death.

Prion diseases comprise several conditions. A prion is a type of protein that can trigger normal proteins in the brain to fold abnormally. 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...
Prion diseases occur when normal prion protein, found on the surface of many cells, becomes abnormal and clump in the brain, causing brain damage. This abnormal accumulation of protein in the brain can cause memory impairment, personality changes, and difficulties with movement. Experts still don't know a lot about prion diseases, but unfortunately...

Rapidly developing dementia 2. Difficulty walking and changes in gait 3. Hallucinations 4. Muscle stiffness 5. Confusion 6. Fatigue 7. Difficulty speaking
Oct 21, 1999 · "'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.
Apr 10, 2023 · Prion diseases are rare, fatal neurodegenerative disorders caused by misfolded prion proteins (PrP) in the brain. This can lead to memory loss, behavior changes, and movement problems.
Prion diseases are transmissible, untreatable, and fatal brain diseases of mammals. Their cause is highly unusual: The host’s normal prion protein can, for unknown reasons, malfunction and assemble into structured aggregates called prions that cause infectious brain disease.
