Laura - get a second opinion! Certain surgeons who perform DBS have been pushing for younger patients for quite awhile now; it is not a new notion (and you can't discount some of their motivation being its high cost and value to their practice). But it is not accepted as the right way to go by many. I'd give some thought to going to the Cleveland Clinic, as one option, for an evaluation.
I'd also check out Jackie Christensen's book "Life With a Battery Operated Brain: a Patient's Guide to Deep Brain Surgery for Parkinson's disease"; you can get it at amazon

Please don't enter into this without doing MUCHO research! Do not think that you do not have time - you do - a lot of time! So take it!
