Essential tremors (ETs) are the commonest causes of tremors, along with Parkinson’s disease (PD). It is usually thought that tremors affecting one hand are typical of PD, and in ET, tremors affect both hands. However, in clinical practice, it is not unusual to see patients with ET, who have tremors affecting only one hand. The patient shown in the video above has tremors affecting left arm and head.
Patients with essential tremors respond well to medications such as propranolol and topiramate.
