Causes of Essential Tremor | Essential
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 Cause
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.
Essential Tremor Treatment
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.
