Can brain aneurysms happen to any healthy person at anytime?!

Yes, although they are actually quite rare.

An aneurysm is simply a bulging in an artery. It can happen anywhere in the body. It can be the result of untreated high blood pressure or other medical conditions - or it may have no identifiable cause at all.

Aneurysms can also be congenital (meaning, you were born with them). Some of us are walking about with aneurysms in our heads - we will never know they are there and we may live to be 103 and never have a problem with them. Sometimes an aneurysm will "leak" slowly, causing symtoms that allow it to be identified and treated. Very rarely, an aneurysm will "burst" suddenly, without warning, and cause massive bleeding. In these cases, it's often impossible to get the person into an operating room fast enough to prevent their death. It's very dramatic and so, these types of stories tend to get a great deal of attention in the media and elsewhere, leading many people to have quite irrational fears that the same thing will happen to them!

It's impossible to tell if an aneurysm is present without doing diagnostic testing. It's not feasible nor appropriate to test everyone - this could result in a person, who would otherwise NEVER have a problem, having dangerous and invasive brain surgery.

So yes, sometimes a healthy or even young person can die suddenly from an aneurysm. It does happen - just not very often. Many many MORE young, healthy people die suddenly from injuries, car accidents, and the like.

Short answer- yes
Longer answer- some people are born with a predisposition to make connective tissue which is slightly weaker than normal. Most of these people go through life without any problems, but sometimes it can show up as a weakness in the connective tissue in the wall of one of the arteries in their brains. This artery swells up under pressure from the blood, and gets weaker, until one day it suddenly ruptures. This can happen to a person of any age. If that person also has high blood pressure, it can rupture sooner. In older people, cholesterol buildup in the walls of the arteries can sometimes call the artery wall to get weaker, and to rupture, but more commonly the cholesterol buildup will cause a blood clot to form and break off, which then blocks the artery farther downstream, causing a stroke.
Aneurysms in the brain are rare enough that it just doesn't makle sense to do brain scans on everyone to look for them, but if you have a family hsitory of them, you may ask your doctor if he/she thinks it would be a good idea in that case.

Aneurysms can be genetic or pathological. The "outcropping or bulging" of the blood vessel is called an aneurysm. Some people go through life never knowing that they have one because they are asymptomatic (don't cause problems). When people get diagnosed with an aneurysm they have had headaches or other symptoms that guided their doctors to do a CT or MRI of the head. This is how most aneurysms get found. Hope this helps.
