How Does a Brain Aneurysm Instantly Kill You?

You may have heard stories about people suddenly collapsing dead because of complications in their brains. The most commonly known cause for this are brain aneurysms.

So what makes a brain aneurysm so dangerous? What causes it? Does a brain aneurysm always result in death? To answer all these questions, we have gathered the best rated explanations from the internet below.


A brain aneurysm refers to a structural weakening of a vessel wall, resulting in prominent bulging as blood pressure pushes against it. Typically, these aneurysms arise in major vessels, such as the aorta, basilar arteries, carotids, or any of the vessels composing the brain artery complex known as the ‘Circle of Willis’.

If these aneurysms get severe enough, they can rupture, causing you to bleed out into your brain. Because these ruptures occur in the major vessels, it results in a rapid, dramatic loss of blood flow to your brain. It doesn’t ‘kill instantly’ but depending on the size and location, it can cause rapid loss of consciousness and subsequent death as your brain becomes starved of blood and oxygen.


Well your anus is basically a muscle like most others in your body. As such, it is under a degree of control by your brain. In Brain Anus Rhythm, this control pathway becomes damaged and begins to fire off sporadically. Think of hiccups, except it’s in your butt. At first, you just suddenly lose control for a few seconds…a sudden fart, a bit of leakage. You’re embarrassed but you don’t say anything.

But as the disease progresses, the loss of control begins to move up your bowels like a fire climbing up a rope. Your gut begins to spasm wildly and uncontrollably at random. One second you’re eating your favourite dinner, the next minute your bowels are unloading into your britches with all the force of an exploding tire. Soon you can’t keep anything down, its like throwing sludge down a hallway. As the spasms reach your upper GI, now it’s causing anything you eat to come right back up, which is some small comfort to your now feces-soaked pants and butt.

In the end, you die of dehydration and malnourishment, writhing on the floor as poop and vomit spew forth like foul demons.

Anyway, my mom died of a brain aneurysm a couple years ago, so I’m fairly knowledgeable on this subject.
So first of all, it doesn’t instantly kill you; my mom lived for 17 days after her aneurysm.

But it can be deadly in a few ways. An aneurysm is, of course, a burst blood vessel. So with a brain aneurysm you have a ton of blood bleeding around the brain, and this causes immense pressure inside your skull. This can quickly kill you if they don’t drain your head of some of the blood. Surviving that, it is possible to suffer strokes after the aneurysm, and these can severely damage brain function. My mom had two strokes, and after the second, she had no cognitive function left, so we were forced to take her off life support.


My MIL had 2 aneurysms in her brain, and had no symptoms. Then, one day one of them burst and within minutes she went from “fine and dandy” to a 5 on the Glasgow Coma Scale.
They transported her to the hospital, where we they did CAT scan and told us that she had one giant hemorrhage, and another aneurysm that would have gone eventually if the first one hadn’t.

They explained the treatments available, and told us that none of them really had the power to make much of a difference.. She would most like die in the next few hours, and if she survived she had “no chance of meaningful recovery.” We spent a rough night re-reading our copy of her will and directives. She had indicated that she didn’t want any life or death decisions made for three days, so we did what the doctors recommended. No one expected any good to come of it, but we really wanted to try.

It was truly amazing. It was a hard six weeks of ICU and then rehab, but you wouldn’t be able to tell today that anything ever happened. They did surgery the next day to clamp the area that had burst, and they were able to get the other one as well.

Today she travels all around the south west in an RV, and does all those things we’re all gonna do “someday.”
So, no matter who you are, or how little you think you need it, get a will and directives and powers of attorney and whatever else you need in case someone needs to step in and make decisions for you. It was incredibly helpful as her bills needed paying and we had to go through all the insurance claims to have the ability to just dive in.

More, though, was the comfort of knowing exactly how to proceed when she was deep in a coma. Sure, you may have had conversations with your loved ones about when they want you to pull the plug, but the actual decision is seldom as easy as we’d like it to be. And when you’re the one struggling with letting Mom die but maybe she would have been just fine, or trying to save Mom and dooming her to a vegetative state, it’s good to have Mom’s thoughts right there in black and white.


A Brain Aneurysm wont necessarily kill you, my mother had one while she was sleeping in her bed and recalls waking up to a “Popping” sound followed by the feeling of blood running all the way down the right side of her face under the skin (This is what she can remember after months of regaining her memory) all of her short term memory was gone for a good 6 months at least, It was quite hard to watch her try and do the simplest tasks, and repeatedly do other tasks, because she couldn’t remember if she had done them or not. Example: Finding her car keys (she once even had all her neighbors inside thrashing her house helping her find them) she literally skipped back a few years in memory for a while, so everything current was new to her, over time she got better despite doctors saying it could be permanent and now she has fully regained her short term memory 🙂


When a brain aneurysm bursts (I’m specifically talking about subarachnoid hemorrhages), the main symptoms are a horrendous headache (like you’ve never experienced before), nausea, and sometimes unconciousness. About a third of people will make it to the hospital alive, and about 50% of them will survive the initial trauma.
It can be treated with a few types of neurosurgery. Following the initial trauma, re-bleeding from the aneurysm can be stopped by inserting small metal coils around the area which strengthens the vessel.

It’s ok after that, right?
Nope. Chances are, if you survive the initial event, you’ll be hit in a couple of days with vasospasm, where the blood vessels around the bleed massively constrict. There’s no known cause for this yet, but it’s assumed it’s to do with the toxins created as the blood that “escaped” into the subarrachnoid layer breaks down. This can result in permanent brain damage as not enough oxygen is received in the brain, and although various treatment options exist there is no real evidence that they work (raising the patients blood pressure, for example).
