Complications from "Stem Cell Tourism" in Neurology

"Stem cell tourism," the practice of offering unproven cellular preparations to patients as approved therapy, is rising in neurology. Currently, the experiences of patients and reported complications from these procedures are unknown in the United States. We evaluate academic neurologists' experiences with stem cell tourism and assess perceived competency on discussing this topic with patients. We found a lack of neurologist preparedness to discuss stem cell therapies with patients and an alarming list of unreported complications from these unregulated procedures. We also identified an urgent need for neurologist education and the creation of a national registry for reporting patient complications resulting from experimental stem cell interventions.
