What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether LIFUP, a technique using sound waves to stimulate the brain, can help patients with chronic Disorders of Consciousness like Vegetative State or Minimally Conscious State. The goal is to see if this method can improve their awareness and responsiveness by targeting the thalamus. This technique has been studied for its potential to modulate brain activity non-invasively, showing promise in treating neurological conditions such as epilepsy and Parkinson's disease.

Will I have to stop taking my current medications?

If you are on a psychotropic medication regimen, you will need to keep it stable for at least 4 weeks before joining the study and remain on a stable regimen during the trial.

• BX Pulsar 1002 (LIFUP)

How Is the Trial Designed?

Group I: Treatment LIFUP Experimental Treatment 1 Intervention

LIFUP will be performed at the bedside using frameless stereotaxy. Specifically, the LIFUP transducer will be fit to the patient's head employing adjustable straps, and will be positioned over the patient's left temporal bone to minimize bone absorption and refraction. Accurate aiming will be ensured using the Brain Sight neuronavigation device, customized for tracking our LIFUP transducer. Following LIFUP, the patient will undergo a second EEG session, except for the EEG cap being fit to the patient's head prior to the LIFUP session so that, as soon as LIFUP administration is complete, the EEG paradigm can be promptly administered. The patient will then be allowed to rest (\~1h).The patient will then be administered a second dose of tracer in order to undergo a second PET measurement. Finally, at the end-of-day, the clinical coordinator will collect an Adverse Event Questionnaire and will fit the PSG device for night monitoring.
