Lack of Sunshine Vitamin Linked to Cognitive Decline
"Researchers have for the first time identified a relationship between vitamin D deficiency and cognitive impairment in a large-scale study of older people.
The study looked at almost 2,000 adults aged 65 and over. As levels of vitamin D went down, levels of cognitive impairment went up. Those with the lowest levels of vitamin D were more than twice as likely to be cognitively impaired."
