Essential tremor is a common neurologic problem. It should be differentiated from secondary causes of tremor and Parkinson disease.
Impact of essential tremor
Essential tremor causes motor dysfunction (e.g. a dentist may have to quit his/her job). However, more importantly, the tremor can have a psychological impact on the patient, especially since it usually gets worse in social situations.
Diagnosis
Essential tremor is a clinical diagnosis. A thorough review of the medical history and medication exposures is a good start. Laboratory and imaging tests may be ordered to rule out a secondary cause.
Treatment
The two first-line agents in drug therapy for essential tremor are:
- nonselective beta-blocker propranolol (Inderal)
- antiepileptic primidone (Mysoline)
They can be used alone or in combination.
Severe, resistant, or atypical cases should be referred to a specialist. Botulinum toxin injection and deep brain stimulation are reserved for resistant tremor or for patients who do not tolerate drug therapy.

These are a maintenance treatment or a cure over time for Essential Tremors? Severe cases can be degenerative and become worse over time when untreated so these drug treatments are for early identification of ET, I assume?
ReplyDeleteThere is no cure for essential tremor. More information can be found on the International Essential Tremor Foundation's website: www.esssentialtremor.org
