  • Brain blackout is kind of a dramatic word. I’m pretty sure the article is trying to refer to cortical spreading depression.

    https://www.nature.com/articles/nrneurol.2013.192

    This is a wave of decreased activity going across the brain. It’s not the whole brain though, just a portion, and it tends to happen more often in the posterior brain than anterior. That’s why visual and other sensory auras (posterior brain) auras are more common than motor/weakness auras (anterior brain). The visual aura itself is the spreading wave of decreased activity going across the brain. It happens in primary visual cortex, primarily dealing with lines and colors. Visual space is represented radially on the brain, so it can often be circular. The “fortifications” or lines on the edges some people see come from the fact that it’s neurons that deal with line detection. Pain usually follows shortly after, but we aren’t exactly sure how that works, and this article was posing a possible mechanism to help link these. The main bulk of the visual aura where it’s grey, blurry, and indistinct is the decreased activity itself in the visual cortex. The area can get larger as the wave spreads.

    Deja vu or jamais vu have been reported with migraines, though that’s a very rare aura in comparison. It’s all depending on what parts of the brain are involved with the cortical spreading depression for that migraine aura for that person in terms of what symptom will happen. Deja vu would be more temporal lobe. Temporal lobe is the most common localization for focal epilepsies. So deja vu as a symptom of a neurologic disease would more commonly be seen with seizures (focal seizures are sometimes called auras too, which gets confusing but are inherently different from what is happening in a migraine). But don’t worry, most deja vu is nothing to worry about.














  • Not some home brew theory. And it is very convoluted, but it’s bascially more “one China” policy word games.

    The Taiwanese president unofficially stated in 1991 they do not claim mainland China, but this was never affirmed by courts and there’s no force of law behind it. They cannot officially do this currently without greatly antagonizing China. China’s view is that Taiwan limiting its borders to include only Taiwan and not all of China, would signal the end of the “one China” policy and be a precursor to Taiwanese independence. If Tawain were to declare different national borders that include only the island itself, then China would view it as a violation of their anti secession law passed in 2005, which threatens military force in retaliation. In China’s view, they are another government still within China and still in civil war, without the authority to re-define national borders.

    Continuing to claim mainland China as part of the same country is continuing the current status quo, any deviations from that would be viewed as an attempted separation of “indivisable” China. So the claim to the mainland at this point in history is primarily to not antagonize China and continue the status quo situation.




  • For the United States, it’s not even just some risk of future harm. The standard is much stricter, it’s if “a provider determines that there is a serious and imminent threat of a patient physically harming self or others.” Has to be something very specific and imminent for confidentiality to be breached.

    There are a few more edge cases though, for instance doctors and other healthcare workers are usually mandatory reporters by law, so if they suspect child abuse they are legally obligated to report it. Another one is for infectious disease tracking and reporting, there may also be confidentiality exceptions.
