A single-center registry of patients with acute ischemic stroke, intracerebral hemorrhage, and transient ischemic attack (TIA) who are emergently managed in the stroke care unit in the National Cerebral and Cardiovascular Center (NCVC) to determine change in underlying characteristics, stroke features and severity, process for diagnosis and acute treatment, and long-term outcomes of stroke/TIA patients over the years.
