Your videos and teaching approach are outstanding! The high quality levels of education that can be found on KZitem is astounding. I remember when I first started learning about doing vestibular rehabilitation in the year 2000 the only way to see nystagmus repeatedly (outside of the clinical setting) was to go to Emory University and watch videos on VCR tapes. Now I get to watch your awesome videos while folding laundry! Thanks again.

Thanks Andy! I agree that youtube is an excellent educational tool for teaching vertigo. Otherwise teaching vertigo without videos is like teaching ischemic chest pain without ECGs!

I've had vertigo since 2005 when I woke up with the room spinning and rocking. I was vomiting and retching, unable to stand and completely helpless. I had to phone my doctor. He found me naked and helpless on the floor. I thought I had had a stroke or something. Was hospitalised for a week. It has improved since but any illness makes it worse including what I think was covid (undiagnosed) which really knocked me back. I don't have money for private treatment and have seen a few different consultants and received contradictory diagnoses. It seems that my case is too complicated for them and they don't have the time or are not being paid enough for a medical card patient (Republic of Ireland). My eyes feel like they dart about but I'm told by most I don't have nystagmus. Vestibular exercises help. I was on a course of Ribavirin and Interferon when it started. I'm fairly new to KZitem and will try out the different exercises. My sympathys to all with this condition. People who have never had it don't understand how awful it is. I've actually had people laugh at me, including a medical "professional", after describing it.

What do you mean by “spontaneous nystagmus?” Do you mean nystagmus on eye movements in a cranial nerve test or obvious nystagmus at rest when not looking anywhere particularly. Love your videos- watch the epley one frequently with patients. Many thanks. Essentially vertical nystagmus bad right?
@PeterJohns

Spontaneous nystagmus means nystagmus seen in primary gaze, ie looking straight ahead. It doesn't mean nystagmus that is brought on by positional testing such as the Dix-Hallpike test. With regards to vertical nystagmus, it is commonly seen in a positive Dix-Hallpike test. See this video. kzitem.info/news/bejne/t2p5xXaIh5hieH4

What to do when there Are no Central Features and when there is no Nystagmus? But AvS
@PeterJohns
Жыл бұрын
I personally don't believe that patients without nystagmus have AVS. It's in the original definition. Some people define AVS as acute vertigo or imbalance, and do not require nystagmus for the definition. I think that patients with acute imbalance and no nystagmus have another syndrome as defined by Machner. Machner published a study about the Acute Imbalance Syndrome. "Risk of acute brain lesions in dizzy patients presenting to the emergency room: who needs imaging and who does not?" For patients admitted to the hospital for uncertain diagnosis, if they had persistent dizziness in the ED, had NO nystagmus, but had a new acute change in their gait or ability to stand, 33% of them had lesions on delayed MRI. If they had high risk factors for stroke, 50% had lesions. Since the differential diagnosis of AVS is basically vestibular neuritis vs dizzy stroke, and virtually all patients with VN have nystagmus if you look very carefully for it, removing fixation with a piece of paper and having them look 30 degree off to each side, then if you don't see nystagmus, they don't have VN. And what does that leave you? A lot of strokes. Now, what about those who says they are still dizzy, have no nystagmus and have no objective difficulty walking? Assuming they have no central features, they are probably at very low risk of stroke. This hasn't been studied as far as I know, but I believe it to be true. They could have BPPV. 10% of BPPV complain of a certain amount of constant dizziness. They could have vestibular migraine. It's very common, and in one paper, 10% of AVS was diagnosed as VM. They could have some general medical cause like anemia or hyponatremia or many other causes dizziness not of vestibular cause. I really should make a video about this. Thanks for the question!

@@PeterJohns thank you so much for your answer. This is very much in line with the New Grace Guidelines who advise to use the standing algorithm in Avs( or not:)) without nystagmus. Thank you so much! Another question i have if you have the Time to answer is if New headache with dizziness irrespective of Quality would be an Indication for Imaging to Rule out cerebellar hemorrhage since i encounter a lot of such Patients in the ed.

@@maxlichtenberger7447 Although GRACE-3 discussed STANDING protocol, it didn't have it in their 15 recommendations. I have concerns that if you can walk unaided, but have a clear new problem with gait and no nystagmus that you would be considered a peripheral cause by the STANDING protocol. I think any patient without nystagmus with a new objective change in gait you should be concerned about stroke. In terms of headache, if that was the only thing I could find on screening for central features that was positive and HINTS exam was all peripheral, it would have to be a fairly significant new headache before I ordered a CT head. And I have found if you ask carefully about other dizzy episodes and a history of headaches that are consistent with migraine, vestibular migraine is a much more common cause of vertigo than cerebellar hemorrhage.

Hi Peter, I have been practicing this approach for about 1-2 years. While encountering patient's presenting with acute vestibular syndrome, the head impulse test is probably the most difficult bedside test. Oftentimes the patient's resting nystagmus is quite subtle, which makes observation of the "correction saccade" quite difficult. Thus, many patients with AVS undergoing the big 3 diagnostic algorithm have no central features, no new hearing loss, no skew deviation, no vertical or multidirectional nystagmus. But they have equivocal result of HIT. I usually observe them in the ED for a couple of hours. If their symptom subsides, then I may give them the diagnosis of VN. However I am a bit worried that I could have delay the diagnosis of stroke. How often do you see a patient presenting with posterior circulation stroke and the only neurological deficit is a normal HIT?
@PeterJohns

Jason, in my experience, if a patient has any spontaneous nystagmus due to vestibular neuritis, I can see the abnormal correction saccade fairly easily. I wonder about your HIT technique. I'd be happy to have zoom call to discuss it. In terms of your last question, I have never seen a patient where the HIT was the only clue that it was a posterior circulation stroke. There seems to be quite a variation in how common certain causes of vertigo present to different areas. For instance, Dan Goldman, neuro-ototologist at Johns-Hopkins (colleague of David Newman-Toker) says that they almost never see vestibular neuritis there. I've had people tell me that patients at their hospital with dizziness rarely have BPPV. It's hard to understand sometimes.
