How To Prevent A Brain Aneurysm
No: The general consensus is that 1 in 100 people have a brain aneurysm at some point in their life. There can be a higher risk in families, and anyone with a family history should consider getting checked for the presence of this disease. There is no cure or preventative treatment. ...Read moreSee 2 more doctor answers
Not a subtle event: In the mildest form you would experience a severe headache, most patients who live to tell describe "the worst headache of your life". Patients with a history of headaches (e.g. Migraines) mostly report that this headache is also different from their usual. In more severe forms of a rupture (which is common) the patients mental status is depressed or the patient is comatous. Seizures can occur. ...Read moreSee 1 more doctor answer
A Future Stroke: An aneurysm is a ballooning of an artery with thinning of the wall. Such a ballooning is at high risk for leakage and rupture which, in the brain, will result in an intracranial bleed with a jet of blood causing actual damage to the brain (a stroke). ...Read moreSee 1 more doctor answer
Unknown: There is no good answer to this question because we have only limited data on exactly how, when and why brain aneurysms develop. Once an aneurysm is identified, if it is non-ruptured and small (<5mm in size), we often follow these with yearly tests to see if the aneurysm is enlarging. In these cases, they tend to grow at varying rates or not grow in size at all. ...Read more
Could you tell me if there's a blood brain barrier, how do people get metastatic/secondary brain tumors?
Imperfect barrier.: The blood brain barrier separates circulating blood from the brain proper. The barrier consists of tight junctions in cells lining the blood vessels in the brain as well as a thick basement membrane and processes from astrocytes (structural/supporting brain cells). This barrier helps to limit pathogens (bacteria) and cancers from entering the brain; however, no physiologic system is "perfect". ...Read more
Brain angio: Seconds.Get a more detailed answer ›
Medical terms: Stroke is technically a catch-all phrase for bleeding or lack of blood flow to a brain area from a blocked artery. An aneurysm usually causes bleeding. A computed tomography scan (ct or cat scan) is the quickest way to show bleeding into or around the brain. It can show vessel blockage and lack of blood flow if the affected area is large enough, if questions remain a MRI scan can show more. ...Read moreSee 2 more doctor answers
Depends: Not sure what you mean by "brain bleeding". As for untreated aneurysm, if the aneurysm is small, regular, is in anterior circulation, if you don't smoke, and you have no family history of subarachnoid hemorrhage (aneurysm bleeding) - then chances are you can live long. But the aneurysm must be monitored: if it changes it probably needs treatment. Where is your aneurysm and how big is it? ...Read moreSee 1 more doctor answer
Headache: Most common symptom for a ruptured brain aneurysm is a headache. It is usually described as a "worst headache of life". It can be associated with other symptoms, such as being confused, sleepy, having weakness, numbness, speech or visual difficulty. This requires immediate medical evaluation. ...Read moreSee 1 more doctor answer
Not Likely: Primary angiitis of the central nervous system (pacns), is a rare disorder specifically targeting the CNS blood supply. Its' cause is unknown. It is thought to be triggered by infection but no specific agent has been identified. I could find no association with brain injury. ...Read more
AV fistula: I think you mean: "arterial-venous fistula". It requires a particular type of trauma, usually penetrating, such that the wall of an artery and vein (which always are close to each other) are damaged so that their walls are embedded together and/or heal that way. Think of a knife or needle traversing both vessels and compression of tissue that holds the open open channels together. It's infrequent. ...Read more
