Brief Summary
The primary objective of this multicenter observational study is to determine the effect size of the relationship between DCI and neuropsychological impairment 14-28 days and 3 months after aSAH. Secondary objectives are the feasibility to administer and the validity of the MoCA in an intensive care unit setting, as well as the test/retest reliability of the MoCA in patients with acute brain damage in absence of aSAH.

Outcome Measures
Primary Outcomes (1)
Neuropsychological deterioration on the MoCA
The primary endpoint is the in-subject difference of the MoCA before (48-72h after aSAH) and after the active phase of DCI (3 months after aSAH) between patients with and without DCI. The MoCA scores will be assessed by a neuropsychologist, not involved in the treatment of the patient and unaware of the patient's study group assignment (DCI vs. non-DCI).
3 months after Subarachnoid Hemorrhage
Secondary Outcomes (12)
Neuropsychological deterioration on the MoCA
Up to 28 days after Subarachnoid Hemorrhage (directly after the DCI phase)
Neuropsychological outcome
Up to 3 months after Subarachnoid Hemorrhage
Reliability of the MoCA in patients with acute brain injury
Up to 1 month following acute brain injury
Test-retest reliability of the MoCA in patients with acute brain injury
Up to 1 month following acute brain injury
Correlation between MoCA and CT-imaging
Up to 72 hours after Subarachnoid Hemorrhage
- +7 more secondary outcomes
Other Outcomes (3)
Random number generation
Up to 1 month following acute brain injury
Outcomes in patients with hydrocephalus vs. without hydrocephalus
Up to 3 months after Subarachnoid Hemorrhage
Outcomes in patiens treated surgically vs. endovascularly (aneurysm occlusion)
Up to 3 months after Subarachnoid Hemorrhage
Study Arms (2)
DCI group
Patients that experience DCI, defined as 1. Cerebral infarction identified on imaging or proven at autopsy, after exclusion of procedure-related infarctions; and 2. Clinical deterioration caused by DCI, after exclusion of other potential causes of clinical deterioration will be assigned to the DCI group.
non-DCI group
Patients not experiencing DCI as defined above.
Interventions
There is no intervention for this study. Patients are allocated to the study groups based on whether or not DCI occurs.
Eligibility Criteria
For part 1 of the study, patients with aneurysmal subarachnoid hemorrhage are recruited. For part 2 of the study, patients with acute brain injury are recruited.
You may qualify if:
- For part 1 of the study:
- Consent of the patient or consent of patient's next of kin (plus consent of an independent physician if patient is unable to consent)
- Aneurysmal SAH
- Age: ≥18
- Time of aSAH known (IMPORTANT: at least approximated. Time of aSAH refers to the bleed that lead to hospital admission; warning leaks in the patient history are not considered aSAH in this context)
- Complete aneurysm occlusion therapy within 48h after aSAH
- Glasgow coma scale (GCS) ≥ 13 points at time point 48h - 72h after aSAH
- Fluent language skills in either English, German, French, or Italian
- For part 2 of the study:
- Consent of the patient or consent of patient's next of kin (plus consent of an independent physician if patient is unable to consent)
- Age: ≥18
- Acute brain injury that requires a in-patient treatment, e.g. for (surgical) treatment of a brain tumor, a cerebral hemorrhage, a hydrocephalus, stroke, or traumatic brain injury, with stable neurological and general health status
- Glasgow coma scale (GCS) ≥ 13 points
- Fluent language skills in either English, German, French, or Italian
You may not qualify if:
- For part 1 of the study:
- SAH due to any other cause than aneurysm or structural abnormality of the brain (arterio-venous malformation, dural arterio-venous fistula, cavernous malformation, dissection, tumor, trauma)
- Comatose patients or patients with a reduced vigilance of GCS \< 13 at time point 48h - 72h after aSAH
- No aneurysm occlusion therapy within 48h after aSAH
- Clear signs of arterial vasospasm in the initial (CT-)angiography; indicating that aSAH had occurred already several days prior to admission
- Neurologic or psychiatric diseases other than aSAH that can potentially influence the test-performance of a patient on the MoCA (e.g., dementia, multiple sclerosis, bipolar disorder)
- Foreseeable difficulties in follow-up due to geographic reasons (e.g., patients living abroad)
- Patients who are not fluent in English, German, French, or Italian
- Patients requiring sedative or other medication that would interfere with the neuropsychological evaluation
- For part 2 of the study:
- Instable neurological or general health-status of the patient, that makes a transport of the patient on the ICU or the office for neuropsychological testing impossible
- Suspected fluctuation of the neurological condition and the vigilance of the patient between first and second testing
- Known psychiatric disease that can potentially influence the test-performance on the MoCA (e.g., dementia, bipolar disorder)
- Patients who are not fluent in English, German, French, or Italian
- Patients requiring sedative or other medication that would interfere with the neuropsychological evaluation
