    Let’s take a look at increased intracranial pressure. There are many ways in which intracranial pressure could be increased and we’ve discussed this a few times. For example, if there’s any type of hydrocephalus that could be an increase in intracranial pressure. There are a few other important topics that we have to have to take a look including herniation, resulting in once again increase in intracranial pressure. So there’s a long list of differentials, but here, let’s organize our thoughts and take a look at what happens. We have something called a Monroe doctrine and “brain in a box.” So in other words, let’s say that you have the box, which is then increasing the pressure due to what ever reason in the brain, increasing its pressure. The skull of course contains the brain, the CSF and the blood. And so therefore, any one of those, in which it’s undergoing, let’s say, encephalitis and brain-type of space-occupying lesion. We talked about hydrocephalus or perhaps even subarachnoid hemorrhage with blood. All of this could result in increase in intracranial pressure. Then increase in pressure then displaces something, doesn’t it? And that something that it displaces is going to result in whatever symptoms that your patient is going to experience. And here, let’s say that our patient – Remember we talked about subarachnoid hemorrhage and we talked about hydrocephalus. And with hydrocephalus, at some point in time, if it’s left untreated, don’t you think it’s once again going to displace something? And that something that it displaces may then result in “herniation.” And that herniation is of different types. And all of this, of course, is going to contribute to that already existing increased intracranial pressure. In terms of increased intracranial pressure, think of this as being kind of like a...
