The experiment is led by a team of researchers at Bordeaux University. Led by Professor Hélène Amieva, they visit Village Landais every six months to chat with residents and monitor the progression of the disease. "Early results are quite promising," Professor Amieva tells me. "There is an improvement not only in the brain but also in behaviour." Quite often, people with Alzheimer’s experience behavioural changes; but that isn’t typical here, something that has been documented by Professor Amieva and her team.
