Central nervous system infarction is defined as brain, spinal cord or retinal cell death attributable to ischemia, based on neuropathological, neuroimaging and/or clinical evidence of permanent injury*

Did you know? A time definition for symptoms (< 24 hours) should not be the only diagnostic criteria for TIA. Modern imaging findings obtained by diffusion weighted MRI highlight tissue changes several minutes after transient or permanent ischemic events. Stroke can be diagnosed with MRI findings regardless of symptoms and in less than 24 hours.
