Bad Dreams in Middle Age Could Be Sign of Dementia Risk, Study Suggests (theguardian.com) 50
People who experience frequent bad dreams in middle age may experience a faster rate of cognitive decline and be at higher risk of dementia as they get older, data suggests. If confirmed, the research could eventually lead to new ways of screening for dementia and intervention to slow the rate of decline. From a report: Most people experience bad dreams from time to time, but approximately 5% of adults experience nightmares -- dreams distressing enough to wake them up -- at least once a week. Stress, anxiety, and sleep deprivation are all potential triggers, but previous research in people with Parkinson's disease has also linked frequent distressing dreams to faster rates of cognitive decline, and an increased risk of developing dementia in the future.
To investigate whether the same might be true of healthy adults, Dr Abidemi Otaiku at the University of Birmingham turned to data from three previous studies that have examined people's sleep quality and then followed them over many years, assessing their brain health as well as other outcomes. This included more than 600 middle-aged adults (aged 35 to 64), and 2,600 people aged 79 and older. Their data was analysed using statistical software to find out whether those who experienced a higher frequency of distressing dreams were more likely to go on to experience cognitive decline and be diagnosed with dementia. The research, published in eClinicalMedicine, found that middle-aged people who experienced bad dreams at least once a week were four times more likely to experience cognitive decline over the following decade than those who rarely had nightmares. Among elderly participants, those who frequently reported distressing dreams were twice as likely to be diagnosed with dementia in subsequent years.

That guy is probably going have even worse dreams as the 11th Circuit Court of Appeals just issued a "strongly worded" 29 page ruling (PDF) [nyt.com] granting the DOJ access to the 100 documents with classified markings (quoting from NYT article (below):
The Justice Department “argues that the district court likely erred in exercising its jurisdiction to enjoin the United States’ use of the classified records in its criminal investigation and to require the United States to submit the marked classified documents to a special master for review,” a three-judge panel wrote. “We agree.”
The panel consisted of two Trump appointees — Judges Britt Grant and Andrew L. Brasher — and Judge Robin S. Rosenbaum, an Obama appointee.
Mr. Trump “suggests that he may have declassified these documents when he was president,” the appeals court wrote. “But the record contains no evidence that any of these records were declassified.”
The court went on to say, “In any event, at least for these purposes, the declassification argument is a red herring because declassifying an official document would not change its content or render it personal.”

Some of the dreams (the pieces I can remember) of late (within the past year or so) have been truly weird. They make no sense as to location (places I've never been) or the people involved.
I have woken up in the night, but not because the dream is bad (i.e. I'm about to be stabbed). I just wake up. Then fall back asleep a short time later (I think. I'm not checking the clock).
This is where science would come in handy. Wear a skull cap to record your dreams then play them back at a later time to see wha
Re: (Score:2)
I read somewhere that the dreams you tend to remember are the ones that happen just before you wake up. So maybe there's some self-selection going on here. So maybe the people that were the focus of the research were the types that easily woke up after a bad dream. Maybe they had lots of "good" dreams as well but they simply slept through it, because, well, why would anyone want to wake up from a good dream?

Me too. It's as if somebody installed a Dall-E bot in my head. Sometimes a dream is very detailed even, weaving actual memories together in weird-ass ways: shit that doesn't belong together is forced together anyhow: a starving Microsoft cat shows up at my door meowing for milk (yes, I speak cat in the dream). I give it milk, then it shits out fidget spinners. I don't even like fidget spinners. I try to touch one, but the cat pulls out an asterisk light-saber to defend it. "Oh, you're an ASCII cat" I say and then pull out an EBCDIC light-saber to compete. How does one tell the difference? I don't know, it's a fucking dream.
My sleeping head seams to have more patience for details and creativity than my day self. I'm kind of jealous of my night head, minus the weird shit.

I'm not a doctor, but I read that as "then you're okay".
The study here seems to have focussed on dreams that woke you up (and so can be remembered, at least to some degree). You're unlikely to remember a dream unless you wake up shortly after it, otherwise your gradual "rise" from REM sleep will give your brain a chance to forget it.
Again, not a doctor here, but if there's really a link, it's probably that you need plenty of healthy sleep - and if you don't get it, then you're at risk of a variety of issues

Then you fit into the baseline, people who did not report bad dreams. There are always chances to have dementia one day, what the article says is that larger chances were observed in people reporting bad dreams.

People who want to remember dreams can do the following
1. Keep a notepad by the bed
2. When going to sleep, remind yourself to write down anything you can remember if you wake up in the night
3. rinse and repeat
It may take a bit, but you will eventually get into the habit of recording your dreams when they are still fresh in your memory

If we found that people who went broke were more prone to dementia, would it be a low bank balance that caused it, or the stressors in their life, and/or not being able to purchase healthy food?
The bad dreams might actually be healthy to have, and it's actually a matter of the distress that causes our mind to want to have them that causes the dementia.
Another way of looking at it might be that while there's a correlation to people who have scars and people who've had a lot of infections, it's not the scars that cause infection, if anything they are part of the process of the body healing.
But yeah, it might be good for doctors to look into giving extra attention to people who report a lot of bad dreams, they could be a warning of there being problems.

If it was a strong enough association then we might use low bank balance as a screening factor.

Well, if you're 45 and "sleep poorly" when you sleep, in the US it probably means not enough time to do so and too many things on your mind when you do.
Let's take two, one-off theories:
1) bad dreams can be a reflection of a non-stop economic/health/family situation where you are trying hard to just keep all of the balls in the air, maybe the kids go to college and you're trying not to think about living too long and requiring long-term care
2) bad dreams are a symptom of poor health or poorly cared for healt
