Essential tremor is a movement disorder that is characterized by shaking that you can’t control.
Often, it starts in the hand or fingers and may progress to involve other parts of the body over time. While it is mostly considered “benign", it can be life-altering and can make work or other activities difficult.
Symptoms
The main symptom is shaking (tremors) that you cannot control. It usually happens on both sides of your body. It often starts in the hands but can also affect the arms, head or torso. Your voice may be shaky as well. The shaking happens when trying to use that body part.
Screening & Diagnosing Essential Tremor
There is no known cause of essential tremor but the shaking may be a result of changes in certain parts of your brain. You are at a higher risk if one or both of your parents had it.
There is no test to diagnose essential tremor. Rather, your doctor will ask about your family history and how long you have had the shaking. Your doctor will watch your movements and do a full neurologic examination. You may have lab or imaging to rule out other causes.
Treating Essential Tremor
There are some medicines, such as beta-blockers or anticonvulsants that may help to reduce tremors. Treatment may include physical therapy to help improve strength and balance and also occupational therapy to help with daily activities. Surgery may be an option for some people while others will not require any treatment.
