I'm going to participate in a research study next month out of Georgetown University that will use transcranial direct current stimulation to attempt to modify the tinnitus signal.
I am aware that other research along these lines has been done, mostly with mixed-to-not-very-inspiring results. However, this study is not a rehash of protocols which have been explored in previous studies, but an entirely new idea (in terms of what parts of the brain are being targeted).
This is exploratory and is not intended as an attempt at treatment; however, I would obviously find it inspiring if it results in any relief whatsoever.
I will undergo three fMRIs as part of this: an initial baseline, and then one more after both a sham DCS session and the experimental DCS session. I will be blind to which session is which; I do not know if the experiment is double-blinded, or not.
I had some mild hesitation about this many MRIs for noise reasons, given that I'll need to wear a headset. However, I have been assured that the headset setup is in-ear, with the earbuds providing roughly the same dB reduction as foam earplugs, and then I will be wearing noise-blocking earmuffs on top of those. I have also been assured that if the volume does not seem tolerable to me once I am in the MRI, I can abort at any time and walk away.
I'm hopeful, though not necessarily optimistic, that this research may lead interesting places... and of course, should it actually diminish my tinnitus even on a temporary basis, then this would provide me with a useful starting point for attempting further tDCS treatment.
If anyone else is in the DC area and wants to see about participating, PM me and I can put you in contact with the MD PHD who is doing the research. Exclusion criteria include: hyperacusis, any current use of anti-convulsant or anti-depressant drugs, history of brain trauma, etc. (I did not ask, but I suspect that the exclusion of hyperacusis patients may have more to do with their ability to tolerate several MRIs, than anything else). Note that the MRIs will not involve contrast, so as long as solid hearing protection is used, there should be very little risk from that. As to risk from the tDCS itself, obviously this is experimental, but from doing a bit of research on tDCS it seems to me that likely adverse effects, are of a limited duration. (And, likewise, if there is any benefit, it is also likely to be on the order of hours-to-days-if-you're-lucky).
My two sessions will both be done by the end of July, and I will provide an update here with whatever transpires.
