Abstract:
Reductions in cerebral blood flow and glucose metabolism have been reported in patients in persistent vegetative state. A few studies have suggested residual cortical activity. Objective assessment of residual cognitive function is difficult because motor responses may be small or inconsistent. In this study, positron emission tomography was used to study covert cognitive processing in a patient in a persistent vegetative state.
