Back in 2009, I was diagnosed with Ménière’s Disease. I’d been experiencing the classic symptoms for a couple of years before that: powerful rotational vertigo; tinnitus; hearing loss; aural fullness. Ménière’s is notoriously difficult to diagnose accurately, but eventually it became clear that my symptoms were very typical and an expert ENT consultant was able to make the diagnosis and then prescribe treatments. I ended up having gentamicin injections, a kind of chemical labyrinthectomy, which were pretty effective at stopping the vertigo. My hearing loss is severe, and the tinnitus remains, and I still have balance problems. Needless to say, any Ménière’s patient also suffers from anxiety, usually brought on by the unpredictability of the condition.The thing about Ménière’s is that it is a measurable set of physical symptoms. Standard audiometric tests can produce diagrammatic representations of the hearing loss. Balance tests and observations of nystagmus (rapid eye movements) can establish beyond doubt the presence of a vestibular disorder. Even tinnitus can be measured to some extent, based on clinical interviews. This is a set of symptoms that clearly exist in the body, originating in the inner ear but then with consequences for the whole vestibular and hearing system.
It has been surprising to me how many autistic people I know also have a Ménière’s diagnosis. There are famous examples too, of whom Chris Packham is the most notable. I have found myself wondering a lot over the past couple of years to what extent these are connected. An ENT consultant I know speculates that migraineurs (people who have migraines) are an advanced form of human being whose extra sensitivities were a decisive advantage during the evolutionary phase of homo sapiens, but are now a disadvantage in the modern world. This sounds a lot like theories of autism as an advanced form of brain evolution. They may or may not be true, but the theoretical parallels are remarkable.
The question in my mind is: where is the boundary between my Ménière’s and my autism? This seems to be a body versus mind question, because Ménière’s is physical with consequences for the mind, whereas autism is neurological with consequences for the body. An autism diagnosis is easy to doubt, as we all know, because the symptomatic outcomes do not obviously point to an underlying physical reality (this is presumably what genetics research is trying to investigate). Yet it is quite clear to me that certain aspects of myself, especially those that have been in evidence since early childhood, cannot be explained by anything other than autism. But there is a grey area of overlap in which it is less clear what might be autism and what might be Ménière’s.
Let’s consider a concrete example. Several years ago, my wife and I went on holiday to the Arctic Circle, flying into Tromsø one dark, cold night to board a ship sailing down the Norwegian coast. This involved going through an airport, one of the most challenging environments for me as an autistic person. This was a few years before my autism diagnosis though. My wife supported me throughout, knowing the difficulties I usually have in airports.
While we were waiting at the boarding gate, I had an attack. I started sweating, the vertigo came on, and I staggered to the toilet expecting to vomit. Nothing happened though, and after a time my wife called me to say that the plane was leaving and we needed to decide whether to board it or not. I still felt terrible, but I decided to press on and staggered down the boarding channel to my seat, where I took out the sick bag and sat throughout the flight with my head in my hands. After an hour, though, I felt much better and we arrived in Tromsø just fine. I had some lingering brain fog but was otherwise able to function well enough.
Looking back on this incident (and I’ve had so many like that over the years) I question what was really going on? Perhaps my lunch had been too salty, but I doubt it. Was this in fact nothing to do with Ménière’s, but rather a shutdown or a panic attack brought on by my autistic response to the airport environment? That is certainly the way I would understand it now. The “vertigo” was qualitatively different to attacks I had had years before. The spinning was not so pronounced and was more a general sense of loss of proprioception. My hearing did not change either, which used to happen during a Ménière’s attack. No, this seems more like the kind of shutdown I used to experience long before the Ménière’s diagnosis. On this occasion, I could only understand it in terms of Ménière’s, but now I think that autism was probably a more likely cause.
Or was it, in fact, a combination of the two? Was autism creating the shutdown, but the body’s response was that of a migraineur or a Ménière’s sufferer? Or was it an overload of anxiety, coming from my response to the airport but connecting with autism somehow by building on anxieties around travel, change and the unknown? My wife was with me, which was great for my support, but I also felt responsible for her too. I wanted to make sure she was happy and having a good time. Perhaps the extra responsibility contributed to the psychological pressure?
So, how best to investigate whether there is any overlap between Ménière’s and autism? What is needed here is some transdisciplinary research. To achieve a more holistic understanding of the possible overlaps and relationships between these conditions requires researchers who are capable of overcoming disciplinary limits. I myself do not have the necessary expertise in either field, but I am sure there are people who could explore this further. The conclusion may be that there is no connection beyond symptomatic similarities. But even the process of investigation could have value in challenging the mind/body distinction that pervades medical and psychological research.
