1/Patient admitted to your service with “syncope” after losing consciousness. You notice this on the right side of his tongue.

What caused him to lose consciousness?

2/You will likely see a lot of people billed to you as “syncope”. I would counsel you to take a step back and frame them as loss of consciousness.

Recall that to have true syncope one needs loss of consciousness + postural tone due to

CNS perfusion.

3/Before landing on true syncope, you need to rule out mimics such as seizure and

gluc that don’t mess with the

plumbing.

I love syncope/LOC because the diagnosis is almost exclusively in history. However every once in a while exam gives it away

4/In a patient who loses consciousness, finding of lateral tongue fighting has been found to be BANANAS specific for:

5/If you said seizure, you are correct! A small study documented the incidence of lat tongue lacs in pts admitted for EEG monitoring and used a retrospec syncope cohort for comparison

Lateral tongue biting ~100% spec, 24% sens for seizure https://pubmed.ncbi.nlm.nih.gov/7487261/

Value of Tongue Biting in the Diagnosis of Seizures - PubMed

Tongue biting, particularly if it is lateral, is highly specific to generalized tonic-clonic seizures.

6/Key takeaways:

Start with LOC before calling it syncope. Check out @StephVSherman and @CPSolvers schema!

Look in pt’s mouths who lose consciousness. It’s free, takes 2 seconds and may massively move the needle diagnostically.

Thanks for tuning in!
