Having recently contacted Alexian Brothers Hospital in Elk Grove, Illinois, about their DBS clinical trials, I was informed that the cut-off age was 70. I'm a man of 71 who has suffered deeply from chronic depression since I was 14 or 15. These clinical trials so close to my home gave me hope that I might be selected to participate in them. I realize that such a study has to have some parameters, but one such trial I came across listed the age requirements as 18 and older, mentioning nothing about an upper age limit. My hopes seemed dashed when I was told by the staff that I was one year above the upper age limit. Is that limit set because researchers don't believe healing is as effective at that age as it is at younger ages. I am otherwise quite healthy and try to swim and work out regularly, and I believe that I could be a good candidate for the study.
