Dementia

Powerful algorithms used by Netflix, Amazon and Facebook can 'predict' the biological language of neurodegenerative diseases, scientists have found.

Big data produced during decades of research was fed into a computer language model to see if artificial intelligence (AI) can make more advanced discoveries than humans. Academics from St John's College, University of Cambridge, found the machine-learning technology could decipher the 'biological language' of cancer and neurodegenerative diseases like Alzheimer’s, Parkinson’s and Huntington’s. Their groundbreaking study could be used in the future to 'correct the grammatical mistakes inside cells that cause disease’.

A significant proportion of dementia deaths in England and Wales may be due to socio-economic deprivation, new research has revealed. 

Such circumstances are also associated with deaths at a younger age due to dementia, as well as poorer access to accurate diagnosis also being uncovered.  The research, led by Queen Mary University of London, examined Office for National Statistics mortality data for England and Wales, and found that in 2017, 14,837 excess dementia deaths were attributable to deprivation, equating to 21.5 per cent of all dementia deaths that year.  The team also found that the effect of this association appears to be increasing over time.

Eating processed meat has been linked with an increased risk of developing dementia - although unprocessed red meat could be protective against the disease.

In a new study of 500,000 people, it was found that consuming a 25g serving of processed meat a day, the equivalent to one rasher of bacon, is associated with a 44 per cent increased risk of dementia. But the findings also showed that eating some unprocessed red meat, such as beef, pork or veal, could be protective, as people who consumed 50g a day were 19 per cent less likely to develop dementia.
