What causes essential tremor, and is there anything that triggers it?

Experts don’t know exactly why essential tremor happens or if there are triggers that cause them to happen. However, there’s evidence that it happens because of the changes in certain parts of your brain.

And while experts don’t know exactly why essential tremor happens, they do know that this condition can run in families. About half of all essential tremor cases are inherited. This condition appears to be an autosomal dominant inherited condition. That means if one parent passes a mutated gene that causes essential tremor to you, there’s about a 50% chance that you’ll inherit the condition.
