Essential tremor (ET) is a medical condition characterized by involuntary rhythmic movements of certain muscle groups in one or more body parts of unknown cause. It mostly affects the arms, hands, or fingers symmetrically; but sometimes involves the head, voice, or other body parts. Essential tremor can be an action tremor and it intensifies when one tries to use the affected muscles during voluntary movements such as eating and writing or it can be a postural tremor, present with sustained muscle tone like head tremor. But it is not a resting tremor like seen in parkinson's disease.
Essential tremor is a progressive disorder, and it is the most common movement disorder in the world. Its onset is usually after age 40, but it can occur at any age. The cause is still unknown. Diagnosis can be made by clinical evaluation
The first step of the Treatment for essential tremor is medication, But unfortunately there is a limited medication alternatives. Clostridium botulinum toxin (Botox) injections and ultrasound are also sometimes used for cases refractory to medications. But all of this treatment modalities effects are very restricted. Deep Brain Stimulation Surgery is ver effective method on treatment of Essential Tremor. In experienced hands the results are very satisfactory.
