Essential Tremor

Essential tremor is a very common but complex movement disorder. Another neurological condition or the side effect of medication does not cause it. It is slow in onset, and usually involves the upper limbs. Titubation (tremor of the head on the trunk) is often present. ET has both a postural and kinetic component, being absent at rest and when limb is relaxed, but present on maintaining a fixed posture (postural) and during movement (kinetic).

As many as 0.5% of the general population may have ET. The prevalence increases with age, and the incidence is bimodal, with a peak in the second and third decades, and also in the sixth decade. It is much more common than most neurologic disease, with the exception of stroke, and more common than Parkinson’s disease, which is characterised by rigidity, akinesia and resting tremor.
