andy,

If she is recommending LENS for concussion, she is violating FDA Regulations and likely just after your money.

Her map is like paint by numbers with just three colors of paint. She likely learned her skills at a weekend seminar.

Len Ochs of Ochs Labs has yet to publish any of his research data supporting LENS. He once has some articles on his web site but has since removed them. He routinely refers to a book supporting his product written by a man (Stephen Larsen) who just did a bit of research and authored a book to sell. It is not peer reviewed nor is it scientifically based. Lots of hype and unfounded claims.

LENS is only to be used for non-medical issues, such a relaxation therapies.

Save your money. You will have a better chance with volitional neuro-feedback. With it, you are taught how to modify though and concentration to increase some brain functions and decrease other brain functions. It is commonly used to help reduce the symptoms of ADHD. It usually starts with a full qEEG to identify brain dysfunctions.
