Thunderclap Headaches

Request an Appointment

Overview

The following tests are commonly used to try to determine the cause of a thunderclap headache.

CT scan of the head. CT scans take X-rays that create slice-like, cross-sectional images of your brain and head. A computer combines these images to create a full picture of your brain. Sometimes an iodine-based dye is used to augment the picture.
Spinal tap (lumbar puncture). The doctor removes a small amount of the fluid that surrounds your brain and spinal cord. The cerebrospinal fluid sample can be tested for signs of bleeding or infection.
MRI. In some cases, this imaging study might be done for further assessment. A magnetic field and radio waves are used to create cross-sectional images of the structures within your brain.
Magnetic resonance angiography. MRI machines can be used to map the blood flow inside your brain in a test called a magnetic resonance angiography (MRA).

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.
