Brain Aneurysm Hereditary
Typically NO: Most brain hemorrhages are due to uncontrolled hypertension. Other common causes include cocaine/amphetamines, tumors that bleed, arteriovenous malformations, aneurysm rupture, anti-coagulant medications, trauma, embolic strokes that bleed and some brain infections.. The complete list is long. Some hereditary conditions that affect the integrity of blood vessel walls, increase bleeding risk. ...Read more
Depends: An aortic aneurysm can be the result of inherited conditions like marfan's syndrome. Conversley, aortic aneurysms may appear 'de novo' in those without a family history and only clinical risk factors such as atherosclerosis and hypertension. Since the relationship between genetics and environment is complex, if there is a family history one should always be extra vigilant and monitor. ...Read moreSee 1 more doctor answer

I do not routinely screen family members but a negative mra can be reassuring. ...Read moreSee 1 more doctor answer
Sometimes: There is good amount of study performed on the natural history of brain aneurysms. Aneurysms under 5 mm tend to have a low rate of rupture an hence not very dangerous. Conversely, the larger aneurysms (specially those larger than 1 cm) are very dangerous and every time they bleed kill 50% of the patients. Hence, if your aneurysm has not ruptured, it is important to discuss the risks with a md. ...Read moreSee 2 more doctor answers
Grapes on a vine: Cerebral aneurysms are out pouch rings of the blood vessels along their normal course. Blood vessels should generally resemble drinking straws which gradually taper as they reach their end. In aneurysms, the arteries bulge out, sometimes very prominently (looking much like grapes on a vine) and posing a substantial risk of rupture because of the stress this places on the vessel. ...Read moreSee 1 more doctor answer
Very rare: I am no aware of a brain or heart aneurism cause by a sepsis or bacteremia by mrsa. Can cause endocarditis, meningitis and encephalitis. Takotsubo cardiomyopathy(broken heart syndrome) is a rare cause of heart failure. Usually cause by a very intense emotional event. Severe infection, by some reference, a very rare cause.
