Researchers in Britain, led by a Greek woman from the diaspora, have developed an innovative artificial intelligence system that can recognize the first signs of dementia in the brain before patients even have the first symptoms and before neurologists can make a diagnosis. The system, which does not need more than one imaging of the brain to draw conclusions, thanks to a special algorithm, has already begun to be tested clinically, although it is too early to say when it will be possible to use it in practice.

A widely used antidiabetic drug, metformin, could be used in the future as a preventative measure for dementia. A new study, led by Dr. Katerina Samara, an endocrinologist of Greek descent in Australia, shows that patients with type 2 diabetes who take metformin show a slower impairment of their cognitive functions and a lower chance of dementia later.
