What causes essential tremors?

ANSWER

The true cause of essential tremor nerve disorder is still not understood, but it is thought that the abnormal electrical brain activity that causes tremors is processed through the thalamus. The thalamus is a structure deep in the brain that coordinates and controls muscle activity.

Genetics is responsible for causing ET in half of all people with the condition. A child born to a parent with ET will have up to a 50% chance of inheriting the responsible gene, but may never actually experience symptoms. Although ET is more common in the elderly -- and symptoms become more pronounced with age -- it is not a part of the natural aging process.
