Have you ever wondered why Lewis Carroll's "Alice in Wonderland" seems like such a trippy and surreal journey? Well, there's a fascinating theory that connects this whimsical tale to a peculiar phenomenon known as "Alice in Wonderland Syndrome" or AIWS. This syndrome is closely associated with migraines and can offer a curious glimpse into the world of distorted perceptions. It has been said that Lewis Carroll himself had migraines, so this may be a tale expressing what he was experiencing personally.

What is Alice In Wonderland Syndrome or AIWS?

Alice in Wonderland Syndrome (AIWS) is a rare and intriguing neurological condition, often linked to migraines. But, it can also be triggered by...

As healthcare providers, our primary goal is to enhance the health and well-being of our patients. One intriguing area of research that has gained attention in recent years is the connection between vitamin D and the risk of Benign Paroxysmal Positional Vertigo (BPPV). BPPV is the most common cause of vertigo, and understanding the role of vitamin D in its development can be crucial in both prevention and treatment. In this blog, we will explore the potential link between these two and discuss how healthcare providers can address this connection in their patient care.

The Importance of Vitamin D

Often referred to as the "sunshine vitamin," it plays a vital role in maintaining our overall...

The intricate complexity of the human body's immune system is a remarkable defence mechanism that protects us from harmful invaders. However, in certain cases, this defence mechanism can go awry, leading to a range of autoimmune disorders. One such disorder that remains relatively lesser-known but can have profound effects on an individual's life is Autoimmune Inner Ear Disease (AIED). In this blog we will shed some light on what AIED is, its causes, symptoms, diagnosis, and available treatment options.

What is Autoimmune Inner Ear Disease (AIED)

Autoimmune Inner Ear Disease (AIED) is a rare condition where the immune system mistakenly attacks the structures of the inner ear, particularly...

Wondering what treatment or exercises to prescribe to your patient with ongoing symptoms after a concussion or associated with vestibular migraines?

With seeing patients with these two conditions over the years you have likely found that they both have something in common. They can both have a component of symptoms that originate from the neck, whether it be headaches and/or dizziness. It is therefore vital to be able to address the neck in order to stop the cycle of ongoing symptoms or at least help them manage their symptoms better. At North 49, a tool that has been useful in determining if the neck is a factor in one’s symptoms and can also guide our treatment is the use of...

With going to vestibular therapy courses have you found that learning how to treat BPPV affecting the anterior canal is often overlooked. This is understandable to some extent given that other vestibular conditions are more prevalent. Specifically with BPPV, according to Bhattacharyya, it only affects the anterior canal up to 3% of the time. Not nearly as common as the other two canals, where much of the training focuses on.

With that being said, BPPV affecting the anterior canal is rare, but it does happen. So, if you are treating patients with dizziness it is just a matter of time until you may see this form of BPPV. When you do it will be good to have a treatment technique up your...

Ever heard of Ewald's Laws?

If not, with assessing BPPV do you ever wonder why:

• With BPPV affecting the posterior canal, going into the Dix-Hallpike Test is more provocative than sitting up after?
• With BPPV affecting the lateral canal, going into the Supine Roll Test the side that is more provocative is not always the affected side?
• With cupulolithiasis affecting the lateral canal, the nystagmus beats towards the affected ear with the Lean Test?

Maybe you have not, but understanding the WHY behind these will help us treat the atypical forms of BPPV. It will also help us determine if there is another vestibular condition at play, mimicking BPPV.

What are Ewald’s...

A recent Instagram post caught my eye as it indicated that given a particular study, clinicians should not repeat positional testing after performing a canalith repositioning technique for BPPV. The reason for this, I believe, was due to the risk of causing the loose otoconia to fall right back into one of the canals.

To be honest this post surprised me. I just assumed that it was common practice now-a-days to repeat positional testing to see the effect of treatment. Don’t we want to evaluate the effect of our treatment? Then, when I went back to find that post and hopefully get the study they were referring to, it was buried deep in the social media abyss.

I was a bit disappointed...

BPPV is the most common cause of dizziness across the lifespan. Fortunately it is usually straight forward to treat. At times it can, however, be a bit tricky, especially if it involves the lateral canal. According to 2017 Clinical Practice Guideline for BPPV  5-15% of the time the lateral canal is involved. When the lateral canal is involved there are several treatment options. One of the newer ones being the Zuma maneuver.

Over the years I have become pretty comfortable treating lateral canal BPPV. I like using the BBQ Roll if canalithiasis is involved. If cupulolithiasis is involved I like using the Head Shake Maneuver. I will then follow it up with the BBQ Roll, if needed.

These...

Have you ever wondered about the relationship between drugs and oculomotor testing? From time to time I was curious, but never looked into it until I received an email a few months ago from Ocular Data Systems asking if I could work with them on a project to provide online lessons regarding vestibular physiology and how to analyze nystagmus findings for law enforcement officers, prosecutors, and toxicologists.

It seemed like a unique opportunity, a Canadian physical therapist helping educate law enforcement officers, prosecutors, and toxicologist from the USA. What I did not realize until then is that there is a group of very highly trained non-medical professionals who perform oculomotor...

I am not sure any of you watched the NFL game with the Bills and the Dolphins on Sunday September 25, 2022? If you did you would have seen the Dolphin’s QB Tagovailoa get pushed backwards, causing him to fall and hit his head on the turf. He was able to get up on his own. However, as he jogged across the field his legs looked like the scene of Bambi on the ice. If you missed it, here is a REPLAY.

With that, if you are like me, you were thinking that he was definitely going to be out for the rest of the football game. Then, the shocker came when he was allowed to resume play.

Did he sustain a concussion?
