(Knowridge) An international team of scientists have confirmed the discovery of a major cause of dementia, with important implications for possible treatment and diagnosis.

Professor Garth Cooper from The University of Manchester, who leads the Manchester team, says the build-up of urea in the brain to toxic levels can cause brain damage – and eventually dementia.

The work follows on from Professor Cooper’s earlier studies, which identified metabolic linkages between Huntington’s, other neurodegenerative diseases and type-2 diabetes.
