Tremors meaning: Tremor is a rhythmic movement

Tremor is a rhythmic movement of a body part that’s out of your control. It can affect many parts of your body and have various causes, such as medications, brain damage or neurodegenerative conditions. Learn about the types, diagnosis and treatment of tremor. Occasional tremor is felt by almost everyone, usually as a result of fear or excitement. However, uncontrollable tremor or shaking is a common symptom of disorders that destroy nerve tissue, such as Parkinson's disease or multiple sclerosis. Tremor may also occur after stroke or head injury. Other tremors appear without any underlying illness. Tremor can be a medical problem on its own, or a symptom of another condition. Learn about different types, from essential tremor to Parkinsonian tremor , causes, and treatments, and how to tell the difference between normal tremors and ones that might point to a neurological issue. Tremors occur when your brain sends the wrong signals to your body, resulting in involuntary muscle contractions—usually in the hands, but other body parts too.
