Official title: Study of Micro-expressions in Patients With Prolonged Disorders of Consciousness

Run by First Affiliated Hospital of Zhejiang University · NCT06088628 · Data updated 2026-11-12

This study is trying to see if watching emotional videos can help understand the tiny facial expressions of patients with prolonged disorders of consciousness and improve how doctors assess their awareness.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 to 80 with prolonged disorders of consciousness lasting more than 28 days following severe brain injury.

Probably not a fit

Patients with locked-in syndrome or those with contraindications for EEG or MRI examinations may not benefit from this study.

What this trial studies

This observational study aims to investigate micro-expressions in patients with prolonged disorders of consciousness by exposing them to various emotional stimuli. It seeks to classify their levels of consciousness more accurately and assist in clinical diagnosis by complementing existing scales like the CRS-R scale. The study will involve approximately 200 participants, including both patients and healthy controls, and will utilize assessments of responsiveness, EEG, and MRI data to explore residual brain function. Follow-up evaluations will be conducted over a period of six months to monitor changes.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and diagnosis of consciousness disorders, leading to better patient management.

How similar studies have gone: While the approach of studying micro-expressions in this context is relatively novel, similar studies have shown promise in understanding consciousness and brain function.
