Brief Summary
This registry was created to assess management parameters of patients treated for aneurysmal subarachnoid hemorrhage in Switzerland. All Swiss hospitals with a neurosurgery department, an intensive care unit and an interventional neuroradiology team that treat neurovascular emergencies participate in the registry. Clinical parameters are entered into a common database. This database will provide (1) a nationwide assessment of the current standard of care and (2) the outcomes for patients in Switzerland including neuropsychological assessments.

Outcome Measures
Primary Outcomes (1)
Functional outcome as assessed by the modified Rankin scale
The modified Rankin scale is used to represent the level of disability and is divided into 7 categories (0-6). The scale runs from 0-6, running from perfect health without symptoms to death. 0 - No symptoms. 1. \- No significant disability. Able to carry out all usual activities, despite some symptoms. 2. \- Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities. 3. \- Moderate disability. Requires some help, but able to walk unassisted. 4. \- Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted. 5. \- Severe disability. Requires constant nursing care and attention, bedridden, incontinent. 6. \- Dead.
5 years after hemorrhage
Study Arms (1)
Aneurysmal Subarachnoid hemorrhage
Patients suffering from a ruptured cerebral aneurysm are included in the study.

Eligibility Criteria
All patients admitted in Switzerland with a diagnosis of aneurysmal subarachnoid hemorrhage
You may qualify if:
- \- Patients admitted with a proven diagnosis of aneurysmal subarachnoid hemorrhage.
You may not qualify if:
- \- Patients in whom the source of haemorrhage could not be identified (angiogram-negative SAH) or SAH with other causes than cerebral aneurysms.
