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.

The team consists of scientists from The University of Manchester, the University of Auckland, AgResearch New Zealand, the South Australian Research and Development Institute, Massachusetts General Hospital and Harvard University.

The latest paper by the scientists, published today in the Proceedings of the National Academy of Sciences, shows that Huntington’s Disease – one of seven major types of age-related dementia – is directly linked to brain urea levels and metabolic processes.

Their 2016 study revealing that urea is similarly linked to Alzheimer’s, shows, according to Professor Cooper, that the discovery could be relevant to all types of age-related dementias.

The Huntington’s study also showed that the high urea levels occurred before dementia sets in, which could help doctors to one day diagnose and even treat dementia, well in advance of its onset.
