Schiff and colleagues’1 reply to criticism that deep brain stimulation (DBS) for the minimally conscious state is a “halfway” solution, whereby “progress in digestion and mobility” may ethically clash with a heightened awareness of disability on the part of the patient, a likely liability.
We encountered the same criticism when we announced in December 2008 that, following bifocal extradural cortical stimulation in the setting of a proof-of-principle study (Project Lazarus), a patient in a permanent vegetative state (19 months) became minimally conscious, with improved digestion and mobility.2
