"Despite the fact that benzodiazepines have been widely prescribed for decades, this survey presents significant new evidence that a subset of patients experiences long-term neurological complications," said Alexis Ritvo, M.D, M.P.H., an assistant professor in psychiatry at the University of Colorado School of Medicine and medical director of the nonprofit Alliance for Benzodiazepine Best Practices. She said the medical community must reevaluate how it prescribes benzodiazepines. 

The study was a collaborative effort between CU Anschutz, Vanderbilt University Medical Center, and several drug advocacy that specializes in raising awareness of benzodiazepine harms.
