Amnesia, Cerebral Aneurysm, Subarachnoid Hemorrhage

Brief summary

To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.

Detailed description

Cohort register is made by experienced neuropsychologists in our institute. MR imaging and data storage is in the department of diagnostic radiology of our institute. MR images are evaluated by two neuroradiologists using a work station.
