Pan Jiahui, associate professor of the School of Software, SCNU, has published a research paper “Prognosis for Patients with Cognitive Motor Dissociation Identified by Brain-Computer Interface” in Brain. The study extends current knowledge of the prognosis for patients with cognitive motor dissociation.

The study suggests that coma patients with cognitive motor dissociation have a better outcome than other patients with disorders of consciousness. These findings have important implications for brain-computer interface-based clinical diagnosis and prognosis for patients with disorders of consciousness.

Cognitive motor dissociation describes a subset of patients with disorders of consciousness who show neuroimaging evidence of consciousness but no detectable command-following behaviors. The prognosis for this type of patients remains under-investigated.

To solve this important clinical problem, Pan Jiahui’s team proposes a multimodal brain computer interface technology to establish accurate identification and rehabilitation prediction methods for patients with cognitive motion separation.

Their study included 78 patients with disorders of consciousness who showed no detectable command-following behaviors. The results showed that within the unresponsive wakefulness syndrome patient group, 15 of 18 patients with cognitive motor dissociation (83.33%) regained consciousness, while only five of the other 27 unresponsive wakefulness syndrome patients without significant brain-computer interface accuracies (18.52%) regained consciousness.

Furthermore, within the minimally conscious state patient group, 14 of 16 patients with cognitive motor dissociation (87.5%) showed improvements in their Coma Recovery Scale-Revised scores, whereas only four of the other 17 minimally conscious state patients without significant brain-computer interface accuracies (23.53%) had improved Coma Recovery Scale-Revised scores.
