Well, encephalitis simply means inflammation of the brain, and it's caused by one of two ways, either through infections, uh, invading the, the person's brain.
And these will be infections that many people will be familiar with, such as the measles, the flu, the herpes simplex virus, which is the cold sore virus.
So infections circulating the system, and in some people it breaches the blood-brain barrier, amounts of direct infectious attack on the brain.
And the second way that people can contract an encephalitis is through their own immune system going wrong and attacking the brain in error.
So it's inflammation of the brain caused by infection or by a person's own immune system going rogue.
Do we know why we get this blood-brain barrier crossing sometimes? Uh, is, are there, are there multiple causes why that might happen, and w- do we not understand that yet?
And of course, all of these things have different mechanisms as to how they might breach the person's blood-brain barrier and, and attack the brain.
And then, of course, we've got problems with the i- the immune system going wrong, uh, and detecting what it perceives to be things in the person's body that it wants to fight, but actually probably shouldn't be fighting.
