The researchers looked at 181 potential risk factors, and then estimated how likely they are to predict dementia and cognitive impairment for people two, four, and 20 years after they turn 60.

This type of visual attention problem is one of three major components (the others being optic ataxia and optic apraxia) of Bálint's syndrome, an uncommon and incompletely understood variety of severe neuropsychological ...
