Key findings

  • 55.4% had futile recanalization at 90 days
  • Higher central beta power lowered odds of poor outcome
  • Adding beta power raised prediction AUC from 0.557 to 0.719

In 56 stroke patients after clot removal, a short EEG taken about a day later was analysed. Higher central beta power was linked to lower odds of poor outcome despite reopened vessels, and improved prediction over clinical factors.
