NCT02650687

Brief Summary

This study will recruit surgical patients more than 65 years old. Patients who participate will wear a sticker on their forehead during surgery which monitors their brain waves (electroencephalogram, EEG) and participate in memory testing before and after surgery. Brain wave patterns will be compared between patients who have problems with memory and thinking after surgery and those who do not. The hypothesis is that there will be characteristic brain wave patients for who will go on to have problems with memory and thinking after surgery.

Study Population

Eligible patients will be identified through the computerized scheduling system at the Icahn School of Medicine at Mount Sinai.

You may qualify if:

  • years of age and older
  • having major elective non-cardiac surgery requiring general anesthesia requiring at least a 2 day hospital stay

You may not qualify if:

  • previous diagnosis of dementia, stroke, cardiac or intracranial surgery
  • inability to consent or communicate in English or Spanish
  • major uncorrected hearing or vision deficit, Parkinson's disease, or major psychiatric disease which will be determined by phone interview and computer medical records abstracted by the primary investigator.
