So, what's happening in our brain when we sleep to prevent this? Scientists found something called the glymphatic system, a clean-up mechanism that removes this buildup and is much more active when we're asleep. 那我们睡觉的时候,大脑是如何防止这些发生的呢?科学家们发现了一种叫glymphatic syst...
You may also need medicine to decrease pain, reduce brain pressure, or prevent seizures. Surgery may be needed to stop the bleeding or remove blood that has leaked out of the blood vessels. A tube may be placed in your skull to drain fluid. This will help decrease pressure in your brain...
