Berry aneurysm, Cerebral aneurysm, and Intracranial aneurysm are names affiliated with the commonly know brain aneurysm.there is also a difference in symptoms of a growing aneurysm and a ruptured aneurysm. There is also a difference in needed treatment for ruptured and burst aneurysms. If a brain aneurysm presses on nerves in your brain, it can cause signs and symptoms. These can include •A droopy eyelid •Double vision or other changes in vision •Pain above or behind the eye •A dilated pupil •Numbness or weakness on one side of the face or body Treatment depends on the size and location of the aneurysm, whether it is infected, and whether it has burst. If a brain aneurysm bursts, symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, loss of consciousness, and signs of a stroke. Any of these symptoms requires immediate medical attention A burst cerebral aneurysm may be fatal or could lead to hemorrhagic stroke, vasospasm (in which other blood vessels in the brain contract and limit blood flow), hydrocephalus, coma, or short-term and/or permanent brain damage. There are two treatment options that have been primary. Clipping, which is identifying the damaged blood vessel and putting a clip across the aneurysm and coiling, which identify the aneurysm, and fill it with coils of platinum wire or with latex. The clipping method prevents blood from entering the aneurysm and causing further growth or blood leakage. Where as the coiling method prevents further blood from entering the artery of the aneurysm and solves the problem.

An intracranial aneurysm (also called cerebral or brain aneurysm) is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel.

Subarachnoid haemorrhage[edit] Main article: Subarachnoid hemorrhage § Signs and symptoms If an aneurysm ruptures, blood leaks into the space around the brain. This is called a subarachnoid hemorrhage. Onset is usually sudden with no prodrome, classically presenting as a "thunderclap headache" worse than previous headaches.[5][6] Symptoms of a subarachnoid hemorrhage differ depending on the site and size of the aneurysm.[6] Symptoms of a ruptured aneurysm can include: a sudden severe headache that can last from several hours to days nausea and vomiting drowsiness, confusion and/or loss of consciousness visual abnormalities

Risk factors[edit] Intracranial aneurysms may result from diseases acquired during life, or from genetic conditions. Lifestyle diseases including hypertension, smoking, excess alcohol consumption, and obesity are associated with the development of aneurysms.[5][6][7] Cocaine use has also been associated with the development of intracranial aneurysms.[6] Other acquired associations with intracranial aneurysms include head trauma and infections.[5]

Signs and symptoms
A small, unchanging aneurysm will produce few, if any, symptoms. Before a larger aneurysm ruptures, the individual may experience such symptoms as a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness, or the individual may be asymptomatic (i.e., experiencing no symptoms at all). Symptoms of a subarachnoid hemorrhage differ depending on the site and size of the aneurysm. Symptoms of a ruptured aneurysm can include:
 * a sudden severe headache that can last from several hours to days
 * nausea and vomiting
 * drowsiness, confusion and/or loss of consciousness
 * visual abnormalities
 * meningism

The risk of a subarachnoid hemorrhage is greater with a saccular aneurysm than a fusiform aneurysm.

Microaneurysms
A ruptured microaneurysm may cause an intracerebral hemorrhage, presenting as a focal neurological deficit.

Rebleeding, hydrocephalus (the excessive accumulation of cerebrospinal fluid), vasospasm (spasm, or narrowing, of the blood vessels), or multiple aneurysms may also occur. The risk of rupture from an unruptured cerebral aneurysm varies according to the size of an aneurysm, with the risk rising as the aneurysm size increases.

Fluid Buildup in the Brain

Blood from a torn aneurysm can block CSF circulation. This can lead to fluid buildup and increased pressure on the brain. Because blood is sprayed around the base of the brain, the possibility of fluid buildup exists, causing hydrocephalus . The open spaces in the brain, called ventricles, may enlarge. It can make a patient lethargic, confused, or incontinent. To stop fluid buildup, a drain may be placed in the ventricles. The tube is called a ventriculostomy, and often drains into a bag at the patient's bedside. This removes leaked blood and trapped CSF.
