Risk factors
By Mayo Clinic staff
There are two known risk factors for essential tremor:
- Genetic mutation. The inherited variety of essential tremor is an autosomal dominant disorder, which means that a defective gene from just one parent is needed to pass on the condition. If you have a parent with a genetic mutation for essential tremor, you have a 50 percent chance of developing the disorder yourself.
- Age. Essential tremor is more common in middle age and older.
