Brief Summary

Neuropsychological and functional long-term consequences of subarachnoid hemorrhages (SAH) represent a great challenge, since sometimes considerable cognitive deficits occur without evidence of substantial brain damage. In this study, we want to examine if the frequently observed memory deficits are associated with hippocampal atrophy.

Eligibility Criteria

Inclusion Criteria: * neurological rehabilitation patients in phase B - D * at minimum eight weeks after disease onset * aneurysmal subarachnoid hemorrhage (Hunt \& Hess grade I or II) * written consent from the patient's legal representative * exclusion of pregnancy Exclusion Criteria: * insufficient cardiorespiratory stability * previous brain damage * mental disorders (dementia, depression) * colonization with multi-resistant pathogens * MRI contraindications * claustrophobia * weight \> 120 kg
