Low Blood Sodium Tied to Impaired Thinking in Older Men


​THURSDAY, Feb. 8, 2018 (HealthDay News) -- Lower sodium levels in the blood are associated with mental impairment and decline in older men, a new study finds.
 
The findings may be of concern, especially because certain drugs often used by the elderly can lower blood sodium levels, experts said.
 
Still, "at this point I do not think we can change our management of persons that fall into this category," said Dr. Maria DeVita, a nephrologist (kidney specialist) at Lenox Hill Hospital in New York City. "Clearly more research is needed."
