Essential tremor (ET) is a neurological disorder that causes you to shake uncontrollably, mostly in your hands, head and even your voice.
ET is not usually a dangerous or life-threatening condition, but the symptoms can impact your quality of life and make many routine activities difficult. If you’re suffering from essential tremor, you may find it challenging to talk or perform tasks that require fine motor skills, such as getting dressed, eating, holding a cup and drinking or writing.
Essential tremor is the most common movement disorder, affecting up to ten million people in the U.S. It can appear at any age, but it’s most common in adults 40 and older. You are also at risk if you have a family history of essential tremor, as researchers believe it can be passed down from a parent.
