When Christine Helm was hit head-on in a car accident with her daughter, she never expected it would change the course of her life. “We had minor, so-called minor injuries,” she recalled. “I had a shoulder injury, a minor neck injury, and a concussion... but mine didn't [get better]. It just hung on and hung on.”

Christine, a former teacher, found herself unable to return to work. Plagued by persistent concussion symptoms and double vision, she visited specialist after specialist—ophthalmologists, neuro-ophthalmologists, neuropsychologists—searching for relief. “I was told that I was left with this partial double vision and a lot of concussion symptoms, and that was just going to be the new me,” she said.
