Patients with unresponsive wakefulness syndrome produce high-amplitude auditory steady-state response

Abstract

The unresponsive wakefulness syndrome (UWS) is one of the unfavorable states that are characterized by a condition of arousal without signs of awareness. Most UWS patients are unresponsive to external stimuli. However, they often open their eyes and are capable of swallowing. In addition, most cases preserve their sleep-wake cycles. These symptoms make it difficult to understand the symptom. The author studied the electrophysiological response of UWS patients, and found a unique means to describe the syndrome.
