Essential Tremor

Overview

Your healthcare provider can diagnose essential tremor based on your symptoms and a neurological examination. There aren’t any tests that can confirm whether or not a person has essential tremor.

However, an important part of the diagnostic process is ruling out other conditions that could cause similar symptoms. Ruling out those other conditions may involve blood tests and imaging tests.

What tests may be done to diagnose essential tremor?

When your healthcare provider suspects essential tremor, they may need to rule out other conditions. The most common and likely tests that help rule out other conditions include:

Blood tests (these can help rule out conditions that look like essential tremor, especially thyroid conditions, Wilson’s disease and toxic exposure to metals like lead or manganese).
Computerized tomography (CT) scan.
Genetic testing.
Magnetic resonance imaging (MRI).
Positron emission tomography (PET) scan.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.

The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:

High blood pressure.
Diabetes.
Heart failure.
Some types of heart valve disease.

Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:

Control high blood pressure, high cholesterol and diabetes.
Don't smoke or use tobacco.
Eat a diet that's low in salt and saturated fat.
Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
Get good sleep. Adults should aim for 7 to 9 hours daily.
Maintain a healthy weight.
Reduce and manage stress.
