Essential tremor

Essential tremor is a nervous system (neurological) disorder that causes involuntary and rhythmic shaking. It can affect almost any part of your body, but the trembling occurs most often in your hands — especially when you do simple tasks, such as drinking from a glass or tying shoelaces.


It's usually not a dangerous condition, but essential tremor typically worsens over time and can be severe in some people. Other conditions don't cause essential tremor, although it's sometimes confused with Parkinson's disease.
