Nap risk link to de­men­tia

Daily Mirror (Northern Ireland) - - THE DIARY -

PEO­PLE who of­ten take a nap dur­ing the day are more at risk of de­vel­op­ing de­men­tia, sci­en­tists say.

They tended to have more tau pro­teins that form tan­gles in the brain lead­ing to the con­di­tion.

Older peo­ple not get­ting enough deep restora­tive sleep had more tau.

Prof Bren­dan Lucey, of Wash­ing­ton Univer­sity, St Louis, said: “The key wasn’t the to­tal amount of sleep, it was the qual­ity.”

Sleep habits could be mon­i­tored to iden­tify those at risk.
