Tinnitus Hub / Talk Survey Results

Well you can put it the other side, I know several people with severe hearing loss and absolutely no tinnitus, so there must be something else that is the reason why some people develop it and other not, I think that this survey is great and answers some of the questions I had.

 

Hi Steve, thanks for the hard work on this!

Some seem to think that tinnitus is always because of some sort of hearing loss, and that hidden hearing loss can't be detected in hearing tests, what's your opinion on this? Seems that it's very hard to say where tinnitus comes from.

Yesterday I met a guy who had tinnitus from a heart attack, which was a traumatic event for him, he has some kind of hearing loss, but he never had tinnitus before, it's so extremely complex.

 

It's easy to argue that. After all we begin to lose hearing very early in life.

I'm not 100% convinced. I have a physical connection to my noise that could very easily be a tinnitus alone and not connected to hearing loss at all. Although you could argue that the jaw / neck issue is related to the ear and hearing in a way.

 

I completely agree with you, and the results from your poll are very clear to me that something else is going on as well.

 

Only about a quarter of tinnitus is noise induced!

That is the data:

28.70% - Don't know the cause
13.73% - Noise-induced hearing loss (continued noise exposure, occupational noise)
9.59% - Acoustic trauma (explosion, exposure to gunfire or extremely loud, sudden noise)
8.33% - Other (please specify)
7.65% - Virus (ear infection, flu, cold)
6.42% - Spontaneous onset (no apparent cause)
4.84% - Psychological (stress, anxiety, depression)
4.56% - Ototoxic (from drugs or medication)
2.87% - Age-related hearing loss
2.79% - Head or neck injury
2.39% - Sudden hearing loss
2.31% - Meniere's
1.47% - TMJ (issues with the jaw)
1.00% - Ear wax procedure (syringing, candling or other related procedure)
0.68% - Dental treatment
0.66% - Barotrauma (due to change in barometric or water pressure)
0.62% - Ear wax build up
0.60% - Otosclerosis
0.40% - Allergy
0.38% - Metabolic (diabetes, thyroid, B12, hyperlipidaemia etc.)

 

Where do you see 66% respondents who indicate hearing loss??

 

How many people was this out of?

 

I’m almost sure the top category (none known of) also contains a significant amount of individuals with hearing loss to some degree. Losing 3-4% is not exactly obvious. I was probably there when my ears decided to collapse another 8-10%. Fun times.

 

I'm not sure anymore, but it's weird to hear people like the daughter of a friend who had maxillary surgery and got rid her loud tinnitus, she didn't had hearing loss.

I have moderate hearing loss, but just went through a very difficult and stressful period and guess what? Just got a new tinnitus sound in left ear, but am almost rid of my low buzz in left ear, so if that's possible then other forces are at play here too not just hearing loss

 

This is brilliant. Thank you!

Is there anyway to get more of a breakdown regarding the 20.28% whom saw a BIG improvement from "Other (Please Specify). Is there any similar trends in that qualitative data?

That is a rather large portion of the community who are getting success from something!

 

It would be very interesting to correlate the causes with that data!:

Where do you perceive your tinnitus?
One ear 24.70% (1,239)
Both ears 38.57% (1,935)
More in the brain 6.58% (330)
In the ear/s and the brain 28.60% (1,435)
Not sure 1.55% (78)

btw: in my opinion the percentage of both ears is rather high...

 

Nobody seems to be interested...

Whether one ear or both ears, it's just tinnitus.
With such an attitude towards diagnostics, there is no need to worry about therapy...

 

Actually we talked about it yesterday. Sometimes these things are not fast, we're not data analysts and you must appreciate that we do this in our spare time. @Hazel has been doing some analysis, she may be able to post a chart.

 

Head and neck injury, TMJ and other issues and dental treatment added together total 4.97 percent. That figure may be 20.00 percent if neck issues were added as most professional say. Otosclerosis as a factor is much higher for those over 40.

Even with what I said above there are so many things to consider. It's not that simple. Some say that most with tinnitus have at least a little hearing loss. With that a noise exposure can be the straw that broke the camel's back, but the camel's back may also include TMJ and/or neck concerns and/or physical age, etc. It's often just noise for the young, but for those in middle age there's more to consider within the clinical causes per the pathology of tinnitus.

Spontaneous onset and don't know the cause can relate to the paragraph above or something else, maybe a combination of causes on the list. So because of that I do applaud the survey and all the effort involved.

 

This is amazing. Have you had a chance to do any multivariate regression analysis? And rule out the usual violations such as omitted variable bias, irrelevant variable, heteroskedasticity etc in the data set?

 

There has been some analysis. One of the students in the ESIT program has analysed the data and will be doing more work on it. I'm not 100% on what he has used but in the next post I will attach his posters from the recent TRI conference.

We're unfortunately not geared up internally to do full-on statistical analysis, although Hazel has done a pretty sweet job with Excel so far.

 

Poster from Jorge Simoes, ESIT student and winner of the poster prize at TRI 2018 for most likely to influence the future.

 

Very cool! But why Bayesian?

 

Ahh thanks! That makes sense I suppose.

 

Diagnostic findings can also be gained from the survey.

Even the simple question of whether one or both ears are affected is not uninteresting in connection with the presumed cause.

 

For statistic treatment of this survey that would be interesting to dissociate all those results per group of "cause of tinnitus". For example, it doesn't seem so relevant to me to compare treatment efficiency for 2 persons that don't have the same cause of tinnitus. In others words: focusing the outcomes per cause, not only on one symptom (= tinnitus).

 

So Retigabine without the side effects would be a nice medicine...

 

And luckily Xenon Pharma is working on that (XEN-1101), the thread can be found here. They already passed phase 1a and are planning to release the complete phase 1 results, including the phase 1b data, in the second half of 2018 and to initiate a phase 2 trial by year end. An update on the positive results of phase 1a can be found here. Sorry if you already knew this, I'm just too excited thinking that this medication might be available at some point.

 

Thanks for posting the results of the survey. It was helpful to see the different modes of therapy that people are seeking. However, I didn't see how effective any of the treatments were to the sufferers. That information would be helpful in that perhaps we could try a combination of treatments. Also, it would be great to match up the initial causes of tinnitus with some of the treatments, so like sufferers could isolate said treatments. I suppose that is pretty complicated but would be a useful tool.
