Daytime naps and poor sleep during the night could be sign of hidden Alzheimer’s, scientists warn

DAYTIME naps could be a sign of ­hidden Alzheimer’s, scientists say.

Tests suggested people who regularly nod off during the day are almost three times more at risk of suffering from dementia.

A study shows they are more likely to have harmful brain deposits that trigger the incurable disease.

Scientists say the new findings back previous evidence that poor sleep at night is linked with the deadly disorder.

US researchers studied 123 men and women who had regular brain scans from 1994.

They found those who were often drowsy in the day were 2.75 times more likely to have the highest levels of “plaques”.

These dangerous beta-amyloid deposits clog up the brain and are a trademark sign of ­Alzheimer’s.

Scientists from Johns Hopkins University in Baltimore, Maryland, said in a report: “There is no cure yet for Alzheimer’s disease, so we have to do our best to prevent it.

“Prioritising sleep may help to prevent or perhaps slow this condition.” Around 850,000 Brits currently suffer from dementia and the figure is expected to hit a million within a decade.

Earlier this year medics found just one night of bad sleep boosted levels of harmful brain toxins linked with the illness.
