Poor Sleep Tied to Hardened Brain Arteries in Older Adults

The researchers had shown that fragmented sleep - which is sleep interrupted by frequent awakenings or arousals — was linked with an increased risk of dementia and cognitive decline, Lim told Live Science. "However, there were gaps in what we knew about underlying brain changes that may link sleep fragmentation with these neurological outcomes," he said.

In the new study, the researchers looked at the brains of 315 people who underwent autopsies after they died. The people were 90 years old, on average, when they died, and 70 percent were women. At some point before they died, the people in the study had had their daily activity and sleep monitored for at least one full week. Based on the data from the monitoring, the researchers assessed the quality of the people's sleep.

Of all the people whose brains were examined, 29 percent had had a stroke and 61 percent showed damage in their blood vessels in the brain, which ranged from moderate to severe.

The researchers found that the people whose sleep was often interrupted were 27 percent more likely to have hardened arteries in the brain than people who slept without interruption.

The people whose sleep was often interrupted were also 31 percent more likely to have damage to brain tissue due to lack of oxygen, compared with those who slept without interruption.

The study found an association, not a cause-and-effect relationship, between poor sleep and brain problems. It's possible that interrupted sleep could be either a cause or a consequence of the hardening of blood vessels in the brain and damage to brain tissue, or that some other unknown underlying factor contributed to both sleep problems and the damage in the brains, the researchers said.

Ok, lets think about this. They lived to be at least 90 years old!! And we're worried if sleep issues killed them?! They lived to 90! Of course something finally killed them! But they beat the odds. Good grief. Who would do a study like this?

Probably someone who got a lot of money through a Grant from the Government.

My very sound sleep patterns are interrupted by urges to pee. The urges are caused by drinking beer late into the evening. I wonder if I can get a grant to continue my study?

Maybe the study could be which beers make you pee more at night.

What, maybe 1 or 2 million dollars and 20 years to research it? :)

I was worried till I saw 90 years old, then I smiled and relaxed, no way in hell do I anticipate hitting 90.

Some years back, I read an obituary of a 100+ year old person who had passed. The obit listed the date of death and “suddenly” passed away. I am ashamed to say that I sort of chuckled and thought, “suddenly? who the heck wasn’t expecting it?” :)
