Research Suggests Pulling All-Nighters Can Cause Permanent Damage
First time accepted submitter nani popoki writes "Skipping a good night's sleep can cause brain damage according to a new study. From the article: 'Are you a truck driver or shift worker planning to catch up on some sleep this weekend?
Cramming in extra hours of shut-eye may not make up for those lost pulling all-nighters, new research indicates.
The damage may already be done — brain damage, that is, said neuroscientist Sigrid Veasey from the University of Pennsylvania.
The widely held idea that you can pay back a sizeable "sleep debt" with long naps later on seems to be a myth, she said in a study published this week in the Journal of Neuroscience.
Long-term sleep deprivation saps the brain of power even after days of recovery sleep, Veasey said. And that could be a sign of lasting brain injury.'"
...Shit.
... as I read this at 1 AM when I have to be up at 6:30 tomorrow. Heh. "Tomorrow."
Dec2103 Cut and Paste from internet (I didn't record where): Sleep deprivation has long been established as a helpful tool for the treatment of patients suffering from depression. However, how and why it works are still unknown. Functional magnetic resonance imaging (fMRI) studies have indicated that large-scale brain network connectivity, especially in the so-called default mode network, seems to be changed in depression. Bosch et al. investigated whether sleep deprivation could influence this brain connectivity. They discovered that sleep deprivation decreased functional connectivity between a brain area called the posterior cingulate cortex and the bilateral anterior cingulate cortex. In contrast, connectivity between the dorsal nexus, a region that plays a crucial role in the pathophysiology of depression, and two areas within the right dorsolateral prefrontal cortex was increased. These sleep deprivation–induced changes in resting-state connectivity indicate a shift in dominance from a more affective to a more cognitive network. This shift toward improved cognitive control should be particularly beneficial in depressed patients who suffer from rumination, negative anticipation, and excessive feelings of guilt and shame.
work in progress
Sleep deprivation has been a natural and common occurrence throughout human evolution. It seems highly implausible that "an all-nighter" would cause permanent brain damage in any meaningful sense.
I doubt a single all-nighter is going to cause a measurable change to your long term brain function. However, anything that takes a small toll, may become measurable in aggregate after a given number of occurrences.
Regarding human evolution; people generally sleep when it is dark. And with no unnatural sources of light, historically sleep deprivation would not have been anywhere near as common as it has become in modern society.
Being eaten by tigers was also common and natural. Natural is not a synonym for healthy.
This study is a long way from proving anything, but I suspect a lot of people will just dismiss it entirely because they don't want to believe it.
"Natural is not a synonym for healthy."
Unless, of course, you are the tiger.

Not all of us like to pull all-nighters.
For some of us, our brains refuse to stop going overdrive until our mission / project is over.
Since my college days, whenever I am in a mission for something, my brain kicks up to the overdrive, and even if I sleep, it still keep churning and churning, resulting in me having really lousy sleeps, with imageries of what I was doing, what I am going to do, what I ought be doing (some times they are " hints " from the sub-conscious) kept on flashing up in my dreams.
For example: I may be in the middle of a very difficult and confusing debugging job.
After non-stop eyeballing the codes, countless re-and re-re-running of the resulting compilations, I get tired and hit the sack.
But in my dreams, images of the screens popping up, with texts (source code) scrolling up and down and sideways, with my "dream self" doing the "virtual debugging" inside my dreams.
It's a goddamn fucking torture, man.
That is why sometimes I rather pull an all-nighters to get the job done, rather than having those un-ending-loop of imagery invading my sleep.

Research Suggests Pulling All-Nighters Can Cause Permanent Damage in mice. The study was done on mice, not people. While it's an interesting first step, it is not in anyway conclusive that the results also apply to humans.
I browse on +1 so AC's need not respond, I won't see it.
I remember dreaming at a keyboard, and when I snapped awake, I had found that I had typed words from my dream into my code. I decided that it was time to go home at that point.

Anyone who's had children knows that sleep deprivation, and all-nighters, are routine during the first two years.
Although, arguably, bringing up kids involves a certain amount of inherent brain damage anyway.
The older I get (I'm 47), the more staying up late affects me. And by staying up late, I mean anything past about 11:30. Staying up after midnight literally makes me feel ill the next day -- my joints ache and I generally feel unwell.
When I was in my 20s I had to make myself go to bed -- listening to the BBC at midnight was my usual routine, and getting up at 6-630 was no problem.
