Article Synopsis
  • Depth electroencephalography (dEEG) is an advanced technique used to monitor brain activity in patients with acute brain injuries, allowing for the detection of nonconvulsive seizures (NCSzs) that might not be seen on traditional scalp EEG.
  • In a study of 33 adults, a significant number (about 66%) showed highly epileptiform patterns, but only 27% of those with electrographic seizures had clear scalp correlates; subtle clinical signs were observed during seizures.
  • The findings suggest that while many critical patients experience NCSzs, these seizures can often go unnoticed by standard EEG monitoring, highlighting the need for more sensitive detection methods in clinical settings.
