The #Qcollar is based on the idea that jugular compression increases blood in the brain to create a "bubble wrap" effect, which prevents the it from bouncing around inside the skull.

According to the company, this mechanism is found in Nature.

From the company's promotional video, the device is justified based on reducing brain "slosh" by:

1) Replicating the animal adaptations (see 18:00 in video)
3) Replicating effects of "higher altitude" exposure (see 21:57, again at 36:00)

Theres such an important topic that I think we spend far too little time on in #EmergencyMedicine +in the regular press: pediatric #concussions. They're amazingly common-and show up in our EDs nearly 200,000 times/year-but despite thousands of studies, we still know very little.
At the most basic level, we've typically assumed there's no structural damage in concussion. We've called it a functional derangement, with transient loss of neurologic function following brain trauma. Loss of consciousness is not required.
With the advent of more advanced neuroimaging techniques+the development of lab tests like the Banyan Brain Trauma Indicator(a combination of proteins found mildly reliably to be released in head injury), we continue to find structural correlates in what we once called concussion
