Causes of Essential Tremor | Essential Tremor Treatment
Essential Tremor is an uncontrolled shaking or trembling, usually of one or both hands or arms, that worsens when basic movements are attempted.
Essential Tremor is caused by abnormalities in areas of the brain that control movement and is not tied to an underlying disease (e.g., Parkinson’s disease). About 50 percent of patients have a family history of the condition. This condition usually does not result in serious complications, but it can certainly interfere with daily activities and cause distress.
In some cases, physical therapy or changes in lifestyle may improve symptoms. If the condition affects a patient’s ability to perform daily tasks and has a negative impact on quality of life, medication or surgery are considered. Beta-blockers, antiseizure medications, benzodiazepines, and carbonic anhydrase inhibitors often are prescribed. DBS is another surgical option in severe cases of essential tremor that have not responded to medication. A hair-thin wire is implanted in the thalamus and connected to a neurostimulator implanted under the collarbone. The neurostimulator sends electrical impulses along the wire to the thalamus, interrupting signals that cause tremor.
