Challenging Research
Commenting on the research, Aarti Sarwal, MD, professor of neurology and section chief, Neurocritical Care, Virginia Commonwealth University, Richmond, Virginia, noted that this was a “very challenging” study to perform, given that only a few academic centers are equipped to perform both fMRI and quantitative EEG analysis.
“In general, finding patients this far out, who have access to clinical, radiological, and electrophysiological testing and were provided good care enough to receive these, is a mammoth task in itself.”
Dr. Sarwal said the study builds on efforts of the Curing Coma campaign , a clinical, scientific, and public health effort of the Neurocritical Care Society to tackle the concept of coma as a treatable medical entity.
“It continues to highlight the challenges of prognostication in acute brain injured patients by showing a higher presence of cognitive function than previously perceived,” she said.
Dr. Sarwal believes that the study’s largest impact is underscoring the need for more research into understanding the degree and quality of cognitive processing in patients with a disorder of consciousness. But it also underlines the need for a “healthy debate” on the cost/benefit analysis of pursuing such research, given the limited number of patients with access to resources.
“This debate needs to include the caregivers and families outside the traditional realms of stakeholders overseeing the science.”
Although communication with comatose patients is still “a ways away,” this research is “a step in the right direction,” said Dr. Sarwal.
The study was funded by the James S. McDonnell Foundation and others. Dr. Schiff and Dr. Sarwal report no relevant financial disclosures.
