Brief Biography

Dr. Cecil Hahn joined the Division of Neurology at The Hospital for Sick Children (SickKids) as a Clinician-Investigator in 2006, with expertise in paediatric epilepsy and neurocritical care. Dr. Hahn directs the SickKids ICU continuous EEG monitoring program, and has led the implementation of clinical guidelines for EEG monitoring in the neonatal, paediatric and cardiac intensive care units.

Clinical Care Activities

  • Epilepsy
  • Neurocritical Care
  • Care Continuous EEG Monitoring in Intensive Care Units

Research Interests

Dr. Hahn is principal investigator of a multi-centre prospective study of seizures among comatose critically ill children, with goals to measure the prevalence of seizures, characterize patients at risk for seizures, and measure the impact of these seizures on functional and neuropsychological outcomes.

His research group also continues to investigate the utility of quantitative EEG trending displays to assist with seizure identification among critically ill infants and children.  

In addition, Dr. Hahn has a leadership role in an international research consortium on critical care EEG monitoring, through which he and his group are contributing to several collaborative multi-center studies.
