Decreased Severity of Brain Infarct Can in Part Explain the Decreasing Case Fatality Rate of Stroke

Abstract

The severity of symptoms of brain infarcts has decreased and can in part explain the decreased case fatality rate of stroke in Finland. However, the change in patients with intracerebral hemorrhage may be overestimated due to undiagnosed intracerebral hemorrhages in the first register resulting from the lack of brain CT.
