I can give you a good objective answer, but it won't be too brief. I live very near Drake but did a lot of on line and phone research of many opportunities before I decided to go to Drake (There are a lot of opportunities to be found as well as devices that you work at home with under the direction of a medical person as well as a Dr Amen and another clinic in Lake Forest). I am an adult so Drake would only do 15 initial sessions "to see if I could respond" to their treatments. I did and at the same time resolved the goal of this whole thing is to separate mental (thought) and physiological stresses and anxieties through the process of relaxation and focus. Soon after, I further resolved that the pace of improvement they set would be extremely expensive so I cancelled my last month's appointments. Also, after about twenty sessions I was not able to reduce the huge amount of medications, which is the original reason for my starting.
I met with them and stated that I was not getting much 'bang for my buck' and would not continue. The result is I will have to take them to small claims court to get my unused deposit returned.
Are they a scam; not an apparent one. The field of neurofeedback is relatively young and not approved by the FDA(?). In retrospect I think that the field is too new and holding field trials with control groups would be very expensive --and what person would want to invest the time and be getting a placebo. These are at least some of the reasons insurance won't cover it.
My biggest disappointments are slow speed of improvement and inability to reduce the medications I am taking.
PS: I have all their relaxation exercises as well as Tai Chi exercise DVD to use if I could just slow down and focus enough to use them.
