Warning Sign? Disrupted Sleep Tied to Alzheimer’s


Warning Sign? Disrupted Sleep Tied to Alzheimer’s

Trouble sleeping inِ middle age couldِ herald Alzheimer’s disease laterِ inِ life, according toِ newِ research linking dementia andِ slumber.
The findings can’tِ yet prove whetherِ disturbed sleep helps contribute toِ theِ brain changesِ that causeِ Alzheimer’s orِ whether someِ otherِ factor links theِ two; butِ preliminary results suggest thatِ treating sleep problems mightِ beِ beneficial forِ the brain inِ the long run.
If sleep isِ foundِ to affect eitherِ the beginning orِ the progression ofِ Alzheimer’s disease, especiallyِ in itsِ early stages, thenِ it’sِ really anِ attractive thingِ to tryِ toِ manipulate, becauseِ getting moreِ sleep orِ betterِ sleep hasِ really noِ risk, saidِ study researcher Yo-el Ju, anِ assistant professor ofِ neurology atِ the Washington University School ofِ Medicine inِ St.

Plaque in the brain

In 2009, Ju’s Washington University colleague David Holtzman published research inِ the journal Science reporting thatِ depriving mice ofِ sleep causesِ a 25 percent increase inِ the levels ofِ a protein fragment called amyloid beta inِ the brain.
So Ju andِ her colleagues, including Holtzman, turned toِ a group ofِ people enrolled inِ the Adult Children Study, soِ named becauseِ half ofِ the volunteers inِ the study areِ children ofِ parents withِ Alzheimer’s.

Sleep and dementia

The results revealed thatِ people whoِ spent moreِ of theirِ time inِ bed tossing andِ turning ratherِ than sleeping wereِ moreِ likelyِ to show abnormal levels ofِ chemicals thatِ indicateِ amyloid beta.
These chemical markers show upِ 10 orِ 15 years beforeِ anyِ sign ofِ memory loss orِ decline, butِ almost everyoneِ who hasِ them willِ eventually develop Alzheimer’s ifِ they don’tِ die ofِ something elseِ first.
Participants didn’tِ necessarily remember theseِ waking periods theِ nextِ morning, Ju said.
