Cerebral Amyloid Angiopathy-Related Inflammation: A Treatable Cause of Rapidly-Progressive Dementia

To the Editor: The first priority of diagnostic evaluation of dementia syndrome is the identification of potentially treatable causes. Cerebral amyloid angiopathy-related inflammation is a recently described diagnostic entity that is characterized by a treatment-responsive, rapidly-progressive dementia syndrome. It has been suggested that it can be noninvasively diagnosed on the basis of a characteristic combination of clinical and radiological features. We present a representative case and discuss typical findings.
