Continuing Trial Responsibilities for Implantable Neural Devices
Published in: JAMA Neurology (October 2023)
Implantable neural devices can offer relief for some treatment-resistant patients with significant disease burden. After the trial ends, patients who keep the experimental implant may need specialized care, hardware replacements, and software updates or else risk worse outcomes (i.e. losing device function, rebound symptoms, exposure to increased risks). The authors offer points to consider for professionals and organizations involved in neural implant trials to address important unmet posttrial needs.
