Loss of consciousness a marker of early brain injury in subarachnoid hemorrhage

The JAMA Network Journals

Mayer, M.D., of the Ichan School of Medicine at Mount Sinai in New York, and coauthors suggest loss of consciousness may be an indicator of a severe bleeding event and therefore a predictor of death or poor functional outcome a year later, according to an article published online by JAMA Neurology.
