TRI Regensburg 2018 Conference Report
Day 1
I forget that my tinnitus can play up a little after long journeys. It's not so bad after a night's rest but still a bit louder than normal (whatever normal means, it's hardly normal having tinnitus), what with the airplane dehydration and travel noise. I can't really complain at 8 hours from my front door to a hotel front door in Bavaria, you have to think of our not too distant ancestors where a journey like this would be in the degree of weeks at best.
The setting of Regensburg is beautiful, such an amazing place to walk around and I got to walk through the park to the conference, the birdsong was most welcome to my tinnitus.
Introductions
Introductions came from the University and from Berthold and Winny of the TRI. Tinnitus Talk were even mentioned in the introduction by Winny! There was also a nice introduction from a representative of COST. Without the COST action we would not be at the conference, they pay the travel expenses that allow us and many of the other EU representatives to attend events like this. The COST action TINNET is a big part of bringing patient opinion and experience to the forefront of tinnitus research.
The first of these meetings was 12 years ago. At that time they say there closer to 30 people, today there are 300 attending. They thanked Matteo De Nora for beginning the whole process with his financial support. Without his substantial contributions tinnitus research would not be where it is today.
Morning Session
I can't go into too much detail on all of the talks right now, so I'll give general impressions of the day. This is purely for time and stomach related reasons, I'm typing before I go for dinner and I have to practise my talk ready for tomorrow.
The first keynote from Tobias Kleinjung had the slightly controversial title "Can Cochlear Implants be a Cure for Tinnitus?". The short answer is not really, unless you have a profound hearing loss, and then temporarily. The primary complaint for a CI is hearing loss, generally over 70dB. Tinnitus is the secondary.
One interesting thing I took from this was that when you stimulate one side only with a CI, in single sided deafness, the "good" hearing ear can also experience a reduction of tinnitus. Suppression is only when using the CI, but it can sometimes last for a time after it is turned off, a kind of residual inhibition.
They aren't certain what the reason is behind this. It certainly wouldn't be a recommended route for those with normal hearing, but if the mechanism is identified it could give data that would really interest me and could inform future treatments not based on CI.
I sat in on the neuromodulation session next. A lot of very interesting presentations on modulating the brain. Richard Tyler presented on findings from MicroTransponder's Serenity System, the implanted Vagus Nerve Stimulation device. I asked later about the sound stimulation they used, interestingly across the audio spectrum, rather than centred only around the tinnitus frequency. Although they have around an octave centred on the tinnitus pitch (as matched by a test) that has no sound played.
There were several sessions on rTMS. I couldn't do them justice without first understanding more about it as I'm not 100% familiar with the intricacies. It was very interesting to see that they have come from a position that it may not be viable, to one that it needs to be designed specifically around the patient. Future projects will look at the comparison between rTMS and direct electrical stimulation.
The final session was on neurofeedback. Based on the findings that people with tinnitus have reduced alpha activity in the brain and an increase of Delta, they tried to influence the Alpha and Delta to separate.
They use visual feedback for their tests; a UFO travelling along a tunnel, alpha brainwaves control the speed and Delta controls direction. The aim is to balance things for a smooth ride. There was no placebo group for the data presented, however they did find that an increase in Alpha activity in those with tinnitus corresponded to a decreased loudness of tinnitus and decrease of tinnitus distress. When they followed up at 3 months the loudness had returned to baseline.
It's a passive process, rather than training a person to focus on Alpha or Delta waves. They found that when the patient tried to focus on a particular brainwave pattern they struggled to control the UFO.
Lunch
At lunch I got talking to a couple of Doctors from Ireland. They don't practice or research tinnitus, but they both have it and have a family history; they attend for the understanding of the current state of research. Really interesting to talk to them, patient to patient, about their impressions.
Straight after lunch we went into the poster sessions. Lots of excellent posters, including the ESIT students. The data from our 2015 survey features in the poster and work of Jorge Simões. Excellent to see his development of it, looking at the treatment successes and relationships between them.
In the centre of the room there was also a really cool iPad demonstration of our treatment data. An excellent student (apologies I forget the name) has created an interactive graphic showing all of the treatments we asked about. You can look at the relationships in several ways, but in essence you place your finger on a treatment name and it displays the connections to other treatments that helped or didn't. I'm not describing too well, I got a brief video but tomorrow I will do a demo and post the video for you to see.
I also got chatting to a couple of people interested in the next survey project we have for trying to profile tinnitus, then test how certain treatments work to see if we can predict success by understanding the case history. I hope we will get to work with them on the project, they want to do the same thing as I do so I think it may happen.
Afternoon
The afternoon keynote came from Hubert Lim. He presented work in animals and non-invasive neuromodulation. The talk was around sound + body stimulation to treat tinnitus. He showed a series of brain scans from stimulation of the body, activating the inferior colliculus. The question was can you control plasticity effects in the auditory system with sound + body stimulation? The evidence certainly appears to support the theory.
It was interesting to note that they gave stimulation to Guinea Pigs via the pinna. They would have used the tongue, but it was too hard because of trying to keep the stimulation device on the animals. Made me think, this seems a positive note for the approach that the Mute Button device has taken.
I really wanted to go to the cortical networks session, but in the brochure they had a summary of each talk and I knew it was going to be too technical for me to grasp. It's an area I want to understand more about but I'm not quite at neuroscientist level yet...
The tinnitus CBT session was good. I know that there are people that aren't a fan of CBT in general, but you just can't deny that it is well researched and has a good success rate. It isn't for everyone of course. The evidence presented adds to that knowledge. CBT from a recent Dutch study is now available as a treatment for tinnitus on the Dutch health care system.
One of the talks in the session revolved around CBTi (CBT for insomnia). Looking at a stat of 50-70% of people with tinnitus reporting sleep disturbance it's definitely something that can help a lot of people. Their initial work has shown good results, they have a Randomised Controlled Trial completing next year.
In the coffee break I chatted to someone who has been data mining from the forum. Unfortunately his talk is in the opposite session to mine tomorrow, so I'm going to try and get a copy of the slides and put the information up on TT.
I went to the session for the COMIT'ID project after. We are currently helping out the discussions by hosting a private forum for participants to debate and agree certain aspects of the outcome domains. We split into groups and debated one of the definitions. It was a very useful session and one that gave me a few new perspectives. It also got quite a few people interested in taking part in the online discussions around the definitions.
Shamefully I didn't realise that there was still a final keynote, so I headed off. I was looking forward to it too. So, if Fatima Husain reads this – I'm sorry. I will try and catch up and get some info from her at some point if I can.
End of Day 1
I haven't been able to type up everything (even though I've typed a lot) but the general impression is very good. I've met a lot of people and have seen the data we've collected here through Tinnitus Talk cropping in in several areas. To know that the work we have done is contributing to research is exciting. The information provided by all of the people that have taken part in our surveys is being put to very good use. There will be more, and we will make sure that the patient voice and patient data are getting out there.
Okay, so this took longer than I thought. I ended up with a fast takeaway and pushed through writing while it was still fresh in my mind.
