My Daughter Suffered A Rear-end Collision About 7 Months Ago

My daughter suffered a rear-end collision about 7 months ago and struggled with symptoms of mild to moderate TBI (as diagnosed by a thorough optometric exam); lots of blurry and double vision, difficulty thinking and processing (college professor noted a huge change) and fatigue, in addition to typical aches and pains. She has recovered mostly from the vision issues through vision therapy and the bodily pain through chiropractic and resuming her exercise regimen, but thinking and processing information is still a big struggle. A naturopath has recommended LENS neurofeedback, but she's unsure. What do you know of this therapy, and is it respected and/or documented outside of the naturopathic community?
