Promoting Recovery After Brain Injury Using Focused Ultrasound

Purpose

The overall aim of this study is to develop an intervention that can help recovery in patients surviving severe brain injury but failing to fully recover. In particular, this project aims to (1) determine neurobehavioral responses to low-intensity focused ultrasound (LIFUP) in patients with disorders of consciousness (DoC) following brain injury, (2) determine neurophysiologic (EEG) responses to LIFUP in patients with DoC and (3) identify and evaluate ethical perspectives of patient representatives (family members and surrogate decision-makers) surrounding investigation of therapeutic neuromodulation technologies such as LIFUP in patients with DoC.

Participants will receive low-intensity focused ultrasound intervention. Participants are also anticipated to undergo advanced MRI and EEG. Surrogate decision makers (family members) and recovered patients will undergo a semi-structured interview.
  • Device: Low-intensity focused ultrasound
    Low-intensity focused ultrasound pulsations (LIFUP) will be delivered to the brain, along with advanced MRI and EEG. Surrogate decision makers (family members) and recovered patients will undergo a semi-structured interview.

Detailed Description

Aim 1: Determine neurobehavioral responses to LIFUP in patients with DoC. Aim 2: Determine neurophysiologic (EEG) responses to LIFUP in patients with DoC. Aim 3: Identify and evaluate ethical perspectives of patient representatives (family members and surrogate decision-makers) surrounding investigation of therapeutic neuromodulation technologies such as LIFUP in patients with DoC. Advanced MRI will be obtained to determine predictive neuroimaging signatures of responsiveness. This project will crucially inform the groundwork for a personalized, connectome-based approach to impactful therapeutic intervention for patients affected by DoC due to diverse pathologies across the brain injury care continuum and will inform an ethical framework for responsible development and deployment of therapeutic neuromodulation technologies.
