A study published in JAMA Network Neurology found that “repetitive heading during a professional soccer career is associated with an increased risk of cognitive impairment later in life” and self-reported dementias in retired male professional soccer players

A recent study presented at the Radiological Society of North America found a significant decline in the microscopic structural integrity of brain tissue and a decline in verbal learning performance for young adult amateur soccer players who performed a high number of headers over two years.

Given that collisions from heading are the main cause of concussions in soccer, the University of Washington Sports Institute saw a need for a program to help teach youth soccer players better heading techniques. As a result, they launched the Aerial program in collaboration with a former professional player and another organization.
