Diffuse axonal injury (DAI)

Diffuse axonal injury (DAI) is a severe brain injury where shearing occurs over a wide area rather than in one focal spot. It typically results from high-velocity rotational forces that stretch axons across the brain. This widespread damage can lead to significant cognitive impairment and long recovery times.

Bottom Line: DAI is a major cause of disability in contact sports; in pre-cinical testing, the Q-Collar was shown to minimize the rotational "slosh" that causes the brain tissues to slide and stretch these fibers across multiple regions.

FAQ

DAI involves more widespread and severe damage to nerve fibers.

It is a severe injury that can lead to permanent cognitive impairment.

Yes. In a pre-clinical study, jugular vein compression reduced damage to brain neurons and axons by 83%.
