Hi @jessicarivera00602 - welcome to Mayo Clinic Connect. My understanding from what you posted is that your teenage daughter has myoclonic epilepsy.

If you've not read it already, you might check out this Mayo Clinic resource on epilepsy, which also talks about myoclonic epilepsy in particular:

- Epilepsy https://www.mayoclinic.org/diseases-conditions/epilepsy/symptoms-causes/syc-20350093

Two additional sources you might look into are:

- Google Scholar: Just type "juvenile myoclonic epilepsy" or similar into your browser, and it will take you to this database. You can type in keywords and filter as you wish to read published studies on juvenile myoclonic epilepsy.

- ClinicalTrials.gov: a website by the U.S. National Institutes of Health where you might find clinical trials based in the U.S. about juvenile myoclonic epilepsy.

You are saying she has not tested positive on any of the tests she's been given thus far? What tests has your daughter undergone?

@jessicarivera00602
About 50% of people with epilepsy never know the cause so it's not that unusual to have normal test results.
When your daughter was salivating, her myoclonic jerks may have advanced to a Tonic (stiffening) seizure. It might be a good idea whenever she has the jerks to go somewhere safe as the jerks may be a precursor to a more serious seizure.
Many people with JME also have Tonic-Clonic seizures.
What time of day does she usually have the jerks?
take care,
Jake
