How is normal physiology affected by a ruptured berry aneurysm?

Blood goes out: Your question is complicated, but a few answers are simple. A ruptured aneurysm will result in the leakage of blood to whatever structures surround the aneurysm. Furthermore, this blood will then exert pressure on the structures likely causing them to malfunction. Ruptured aneurysms are a serious problem and require prompt evaluation and treatment by a physician.

Cerebral physiology: The cerebral and body physiology is affected tremendously after an aneurysm rupture. There is a "burst" blood that emanates immediately from the rupture. This pressure wave leads to coma and/or cardiovascular suppression. This leads to increased intracranial pressure (icp). The blood frequently blocks the normal drainage pathways leading to acute hydrocephalus. This also leads to increased icp.
