virtual reality test to predict alzheimers


Research carried out by German scientists has suggested that Alzheimer's disease can be detected decades before onset, using a virtual reality test. People aged 18 to 30 were asked to navigate through a virtual maze to test the function of certain brain cells.Those with a high genetic risk of Alzheimer's could be identified by their performance,

The scientists, led by Lukas Kunz of the German Centre for Neurodegenerative Diseases in Bonn, say the high risk group navigated the maze differently and had reduced functioning of a type of brain cell involved in spatial navigation. The findings could help future research, diagnosis and treatment, they report in the journal Science.
