Brainwave Optimization is one of the most advanced therapies on the planet. It is especially helpful for recovery from stroke, trauma, PTSD, concussions, addictions, insomnia and compulsions. After the 3rd session many people are saying, "I haven't slept this well in years."
Brainwave Optimization was invented about 15 years ago by a computer scientist, Lee Gerdes, after he was attacked by 3 teenagers, one with a baseball bat.
If you are trying to heal something, I recommend DOING EVERYTHING YOU CAN DO. Also keep in mind the three healing essentials: Nutrition, Lifestyle, and Energetic Medicines, discussed below.
And btw: my #1 solution for depression is the bach flower remedies. Scroll down to Energy Medicines below for more, or go direct to my pageflower essence healing.
Nutrition 1. See your doctor and get some blood work done. Find out your B12 level, your Iron level, and instead of testing your vitamin D level, just start taking vitamin D (the vitamin D test here in Canada is $60. Vitamin D itself is maybe $12.). If you find that you are B12 or iron deficient, or even on the low end of the scale, consult "Dr. Google", and likely you will want to supplement them. *Note: RDA and OPA are not the same. RDA is the minimum amount to avoid getting a disease of deficiency. OPA, or *optimal* amount, is way, way higher. To create health, you may need closer to the OPA than the RDA.
A while back I read an excellent article that described 4 'brain types' in Alzheimers.
You'll see very clearly in this article that Alzheimers/dementia is mostly driven by diet and lifestyle. If the body isn't healthy, likely the brain won't be either.
One of the biggest and most harmful lies ever pushed on us, probably from Big Sugar, was the lie that fat will make you fat.
See that image of the two brains above? The brain on the right is all dried out. You get that way by avoiding fat. Don't do that to yourself! EAT FAT. The BS we have been told about fat making us fat is simply not true.
