Non-vestibular dizziness
Posted , 12 users are following.
Hi there. I've been experiencing dizziness symptoms, starting with symptoms similar to labyrinthitis, for 13 months. After several doctors aapointments, ENT tests, CT scan, MRI and a visit to the neurologist, I was told that there was nothing wrong with my ears or my balance. This is something the neurologist says is common and has been seen for decades but there is no official diagnosis or treatment (even though, that kinda seems like a diagnosis).
I was told it's called disequilibrium because I feel 'out of sorts' all the time and lots of things make me feel unbalanced, disorientated, 'dizzy', I can't always see or focus that well and if i experience 'sensory overload' (too many visual, auditory signals) then my brain just gives up and I end up lightheaded, weak and have 'blacked out' on several occasions (though not lost full consciousness yet, thankfully). If I am tired (dizziness makes me tired which makes the dizziness worse - go figure) then it's game over. I struggle to concentrate for long periods of time, I hate supermarkets, bright screens and lots of discordant or high-pitched noises. The only symptoms I don't have are the head spinning, room spinning sensation and the marshmallow floor feeling of labyrinthitis.
Annoyingly, I had a few days after my initial symptoms where I felt fine and there was no problem. Making me think that it was just labyrinthitisi and it would all clear up.
After being told that 'it might just go away or it might never go away' (thanks!) I needed to find out more. Despite this being 'common' I have yet to hear about or meet anyone else who has this problem.
Some further internet research calls my problem 'non-vestibular dizziness'.
Now i'm looking for anyone else with these symptoms to find out how they experience them, how they cope, and how long they've had this problem. If it's so common, there has to be someone else out there!

The information that I note below is from the Vestibular Disorders Association, VEDA, website. Labrynthitis involves loss of hearing and vestibular neuritis is inflamation of only the major vestibular nerve. This inflamation causes many symptoms and can be hard to properly diagnose.
No specific tests exist to diagnose vestibular neuritis or labyrinthitis. Therefore, a process of elimination is often necessary to diagnose the condition. Because the symptoms of an inner ear virus often mimic other medical problems, a thorough examination is usually done to rule out other causes of dizziness, such as stroke, head injury, cardiovascular disease, allergies, side effects of prescription or nonprescription drugs (including alcohol, tobacco, caffeine, and many illegal drugs), neurological disorders, and anxiety. (the later being Non-vestibular Dizziness)
Symptoms of viral neuritis can be mild or severe, ranging from subtle dizziness to a violent spinning sensation (vertigo). They can also include nausea, vomiting, unsteadiness and imbalance, difficulty with vision, and impaired concentration.
The sensory information provided by both ears is normally symmetrical. Signals coming from the left ear correspond with the information provided by the right ear. Thus, if the vestibular organs in one or both ears are not working properly, the brain receives conflicting signals about movement, resulting in dizziness/vertigo.
A disrupted or impaired VOR can result in abnormal nystagmus, an excessive to-and-fro movement of the eyes, and oscillopsia, where objects appear to bounce because they do not remain fixed on the same point on the retina.
Dizziness is a symptom that is real but is not observable by your doctor. In order to diagnose a vestibular system disorder, your doctor must rely on signs that he or she can observe, such as abnormal eye or body movements. In the early stages of many vestibular disorders these signs may be absent or present only weakly or occasionally. As a result, your doctor may not be able to easily determine whether your dizziness is being caused by a vestibular disorder.
A person with a vestibular disorder may also experience photosensitivity (discomfort with bright light) and other vision problems such as: intense discomfort with flickering lights, particularly fluorescent, sodium, or mercury vapor lights; moving objects; rows of similar objects, such as in grocery store aisles or lines of text on a page; or busy, high contrast patterns, such as polka dots or sunlight filtering through mini-blinds. Environments with a combination of fluorescent lighting and busy patterns or moving objects are especially problematic which is why shopping in large stores may be very difficult. Even environments with subdued décor can be fatiguing if frequent head movements are required, such as when a person converses with others at work or at a social gathering.
Just something to consider.
