Good to know:
"The results, published in the journal Neurology, suggested that it is better for patients to sleep through the surgery.
Additionally, traditional forms of deep brain stimulation surgery often cause patients to lose speech fluency. Matthew Brodsky, MD, an associate professor of neurology at the OHSU School of Medicine and medical director of OHSU’s deep brain stimulation program, believes that this side effect could be related to the use of microelectrodes.
Using microelectrodes, surgeons need to perforate the brain twice — once with the microelectrodes and again to position the electrode and [wire to] battery pack that will remain in the brain."
“Patients undergoing asleep-DBS [deep brain stimulation] had improved speech versus patients undergoing awake DBS, whose speech fluency predictably worsened,” said Brodsky, who is the lead author of the study
