It worked well to get me out of serious suicidal depression that was not responding to medication. It lifted the depression enough that meds were finally able to be put in place that worked pretty well. I had two series of treatments about 4 years apart (9 treatments the first time; 8 the second). Insurance covered the treatments, so expense will depend on what your insurance coverage is. I had some short-term memory issues surrounding the time just prior to and during treatment, but no long-term memory problems.
