About this study
Official title: Head and Neck Cooling as an Emergency Department Therapy to Decrease Progression of Concussive Symptoms
Current therapy of Mild traumatic brain injuries (TBI) revolves around symptomatic care, rest, and return to school/sport/work after symptoms have resolved. The standard intervention for sufferers of mild traumatic brain injury is brain rest, which aims to decrease symptom intensity and duration, prevent re-injury and second impact syndrome via cessation of physical and cognitive activity, and to gradually increase activity as tolerated.
Increased brain temperature can be a secondary injury result in TBI. There are limited studies, primarily in the sports medicine literature, that show head-neck cooling can be a useful adjunct as a treatment for mild TBI. Our objective will be to evaluate concussive symptoms via the Post-Concussion Symptom Severity Score Index by conducting patient follow up interviews at different timepoints over 72 hours after an emergency department visit for the head injury where head and neck cooling was applied.
Read the detailed description
There are limited studies that show head-neck cooling used as a treatment for mild TBI. Increased brain temperature can be a secondary injury result in TBI. For every degree raise in temperature, the brain's demand for oxygen and glucose increases by 6 to 10%. This elevated body temperature is associated with a worse outcome in acute brain injuries like strokes or intracerebral hemorrhages. The research hypothesize is that using head-neck cooling in the acute setting of a mild TBI may decrease the overall symptomatic period following an injury.
This research protocol will utilize a randomized controlled trial, with an interventional treatment arm and a control arm, and primary endpoints revolving around patients' post-concussion symptom severity scores. The treatment arm will receive symptomatic care (see Interventions section below) along with 30 minutes of head-neck cooling in the emergency department while being monitored for side effects. The control arm will receive symptomatic care. The main goal of this study is to evaluate if head-neck cooling of 30 minutes within the first 24 hours of a concussion will decrease the symptomatic severity index score of adults who present after a head injury. In addition, patients will receive Tylenol 500mg twice daily as well as ondansetron 4mg up to twice daily. The Catalyst Cryohelmet will be used to provide head and neck cooling. It comes in three sizes based on head circumference. Once informed consent is obtained then the patient's head will be measured to provide the correct Helmet size. The Cold Packs will be stored in the emergency department freezer and applied to the helmet once the helmet is ready to be applied. The Cryohelmet will be washed between uses. The Catalyst Cryohelmet is registered with the FDA as D344812. It is a Class I (minimal risk) device not requiring pre-marketing or regulatory processes.
Anticipated secondary outcomes include but are not limited to adverse effects relating to application of the head-neck cooling, need for further intervention in the emergency department, and return to baseline function within 72 hours.

Catalyst CryohelmetDevice
The Catalyst Cryohelmet will be used to provide head and neck cooling. It comes in three sizes based on head circumference. Once informed consent is obtained then the patient's head will be measured to provide the correct helmet size. The Cold Packs will be stored in the emergency department freezer and applied to the helmet once the helmet is ready to be applied. The Cryohelmet will be washed between uses. The Catalyst Cryohelmet is registered with the FDA as D344812. It is a Class I (minimal risk) device not requiring pre-marketing or regulatory processes.
| Study group | Role | What they receive |
|---|---|---|
| Catalyst Cryohelmet intervention with symptomatic care | Experimental | The treatment arm will receive symptomatic care (acetaminophen 1000mg and ondansetron 4mg) along with 30 minutes of head-neck cooling in the emergency department while being monitored for side effects. Receives: Device: Catalyst Cryohelmet |
| Control: symptomatic care arm | No intervention | The control arm will receive symptomatic care (acetaminophen 1000mg and ondansetron 4mg). They will not wear any helmets. |

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: Not able to recruit enough patients; many patients lost to follow up). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-Concussion Symptom Severity Score Index case report form (time frame: 0 hour). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05473897, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Nov 2024; AzTrials last refreshed its copy on 28 Oct 2026.
