Tremor is a common neurological movement disorder characterized by involuntary shaking of the body, often affecting the hands but also potentially impacting other parts of the body such as the head, voice, arms, and legs. This condition can be classified into various types based on its cause and pattern, including essential tremor, which is often hereditary, and tremors caused by conditions like Parkinson's disease or due to medication side effects.

Essential tremor is one of the most prevalent movement disorders, typically appearing in middle age or later. It manifests as rhythmic shaking, usually when performing simple tasks like drinking from a glass or writing. While it can be frustrating and embarrassing, essential tremor is usually not a sign of a life-threatening condition. Treatments range from lifestyle changes to medications that can help reduce the severity of symptoms, and in some cases, surgical interventions like deep brain stimulation may be recommended for severe cases.

Understanding tremor is crucial for both medical professionals and patients alike. Early diagnosis and appropriate management can significantly improve quality of life, enabling individuals to maintain their independence and continue engaging in daily activities with greater ease.
