Subjects were divided into four groups based on vitamin D blood levels: Compared with people with optimum vitamin D levels, those in the lowest quartile were more than twice as likely to be cognitively impaired.
A second study, led by scientists at the University of Manchester in England and published online this past May, looked at vitamin D levels and cognitive performance in more than 3, men aged 40 to 79 in eight different countries across Europe.
The data show that those people with lower vitamin D levels exhibited slower information-processing speed. This correlation was particularly strong among men older than 60 years. It is also unclear if giving vitamin D to those who lack it will help them regain some of these high-level functions.
