Research Suggests Pulling All-Nighters Can Cause Permanent Damage 144

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.'"

    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.

    About all that could be really said is that any damage from sleep deprivation didn't tend to kill our ancestors before they bred.

    did you actually RTFA?

    LONG TERM sleep deprivation. As in your lifestyle - swing shifters, etc. Not the occasional amphetamine binge, or caffeine fueled cram/D&D/gaming session.

    never mind the actual experiment they conducted where they found neurons destroyed in the brains of mice that were kept on a wonky sleep schedule.

    our bodies are TUNED to be active during the day, sleep at night.

    probably contributes to jetlag.. see http://en.wikipedia.org/wiki/C... [wikipedia.org] "Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers, commonly the most important of which is daylight."

    Mostly, I agree with what you say. But I do believe that long term sleep deprivation is not healthy. I once read a believable article claiming that sleep clears the brain of waste chemicals, kind of like going to the bathroom. Without losing that waste it starts to build up and poison you.

    Other than that, it's also rather straightforward self-experience. If you feel like shit after pulling 24hrs it's probably because shit is happening to you. Just like when drinking too much alcohol.

    The article isn't about whether you sleep at night or not, it's about whether you skip sleep regularly.
