Distinguishing unresponsive wakefulness syndrome from minimally conscious state remains a major clinical challenge in diagnosis of disorders of consciousness (DOC), with misdiagnosis rates near 40%. I will present work using auditory steady-state responses (ASSRs) as a passive, bedside-compatible marker of awareness. Across studies in patients with DOC and in patients undergoing general anesthesia, low-gamma responses (~40 Hz) were consistently attenuated during reduced or absent awareness, independently of peripheral auditory integrity. I will discuss the underlying mechanisms\u2014likely involving cortical excitation\/inhibition balance and cholinergic modulation\u2014and the potential of 40-Hz ASSR as a supplementary diagnostic tool for consciousness assessment.<\/p>\n\n\n\n
