Decreased kidney function 'linked to lower cognitive functioning'

19 November 2012

Decreased kidney function is linked to lower cognitive functioning, according to new research.

A study from Temple University found that reduced functioning in areas like global cognitive ability, abstract reasoning and verbal memory were associated with decreased kidney function.

Researchers looked at data from 590 people in order to see how much kidney function had changed during this time, and whether it was linked to how much cognitive functioning had altered.

They were predominantly interested in the overall change, as well as in specific abilities like abstract reasoning and verbal memory.

Lead author Adam Davey said: "The brain and kidney are both organs that are affected by the cardiovascular systems.

"They are both affected by things like blood pressure and hypertension, so it is natural to expect that changes in one organ are going to be linked with changes in another."

Mr Davey noted that these results emphasise the importance of diagnosing and managing chronic kidney disease and the extent of decrease in cognitive functioning.
