Official Title: The Silent Cortical Infarcts in the Cerebral Amyloid Angiopathy: Is There a Link With Subarachnoid Hemorrhage?
Brief Summary: The Cerebral Amyloid angiopathy (CAA) is the leading cause of cortical hemorrhage after 65 years. The presence of cerebral infarction is also reported anatomically in the AAC. MRI studies of these infarcts are rare. They are described as punctate, cortical silent. Frequency and pathophysiology is poorly understood. The investigators put the question of a link with hemorrhagic lesions of the AAC.
