Essential Tremor
Essential tremor is a neurological condition that causes rhythmic shaking, most often in the hands, though it can also affect the head, voice, or other parts of the body. It’s one of the most common movement disorders and is distinct from Parkinson’s disease, though the two are sometimes confused.
Signs & Symptoms
- Shaking that occurs during purposeful movement, such as writing, eating, or holding an object — unlike Parkinson’s tremor, which is more common at rest
- Tremor that may worsen with stress, fatigue, or caffeine
- In some people, a shaking or quivering voice
Causes & Risk Factors
The exact cause isn’t fully understood, but essential tremor often runs in families, suggesting a genetic component.
Diagnosis
Diagnosis is based on a neurological exam and the pattern of the tremor; imaging or other tests are sometimes used to rule out other causes.
Treatment Options
Many people manage essential tremor with medication. For tremor that significantly affects daily life and doesn’t respond well to medication, surgical options such as deep brain stimulation may be considered.
