Stroke-like episode

What it means

No consensus exists on what a stroke-like episode is, but these episodes can be functionally defined as a new neurological deficit, occurring with or without the context of seizures, which last longer than 24 hours.

Stroke-like episodes are phenotypic features predominantly of mitochondrial disorders, most frequently mitochondrial encephalopathy, lactacidosis, SLE (MELAS)-syndrome, and mimic the clinical manifestations of ischemic stroke to some extent.
