Down syndrome, like Alzheimer's, is a double-prion disorder

The brains of people with Down syndrome develop the same neurodegenerative tangles and plaques associated with Alzheimer's disease and frequently demonstrate signs of the neurodegenerative disorder in their forties or fifties. ...

Neurodegeneration can be studied long before symptoms arise

Many changes take place in the brain long before symptoms appear. This has been shown in mice in two studies of prion diseases in which the brain gradually deteriorates. The results suggest that changes can be studied extremely ...

Discovery illuminates how brain cells die in prion diseases

Prion diseases, such as Creutzfeldt-Jakob Disease (CJD), are fast-moving, fatal dementia syndromes associated with the formation of aggregates of the prion protein, PrP. How these aggregates form within and kill brain cells ...

Viral infections could promote neurodegeneration

Some viral diseases could possibly contribute to neurodegeneration. DZNE researchers report this in the journal Nature Communications. Their assessment is based on laboratory experiments in which they were able to show that ...

Prion diseases: New clues in the structure of prion proteins

Prion diseases are a group of rapidly progressive, fatal and infectious neurodegenerative disorders affecting both humans and animals. Bovine spongiform encephalopathy (BSE) or "mad cow" disease is one of the most famous ...
