Understanding Tremors: Causes, Types, and Treatments

Essential tremor is a nervous system condition, also known as a neurological condition, that causes involuntary and rhythmic shaking. It can affect almost any part of the body, but the trembling occurs most often in the hands, especially when doing simple tasks, such as drinking from a glass or tying shoelaces.

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

Tremors Symptoms

Essential tremor symptoms:

• Begin gradually, and usually are more noticeable on one side of the body.
• Worsen with movement.
• Usually occur in the hands first, affecting one hand or both hands
• Can include a "yes-yes" or "no-no" motion of the head.
