Headaches can strike suddenly. A thunderclap headache occurs when you have an extremely intense headache that lasts for a short period of time, similar to a lightning strike. Learn more about the causes and how to manage them.
What is a thunderclap headache?
A thunderclap headache, as the name implies, is characterized by sudden onset and intense pain, similar to a lightning strike. This headache can occur without an underlying medical cause, but if it occurs on a regular basis, it could be a serious sign of brain bleeding.
Thunderclap headaches are extremely rare. In some cases, this type of headache is not serious and has no underlying medical cause. However, if you are experiencing such headaches, you should see a doctor for an appropriate examination and treatment.
Symptoms of thunderclap headache
Thunderclap headaches are characterized by severe pain. Symptoms include:
- Sudden and extremely painful onset
- Intensifying within 60 seconds
- Nausea or vomiting
- Possible loss of consciousness
Thunderclap headaches can be triggered by specific activities or occur without any apparent cause. This headache usually peaks, like a lightning strike, or reaches its worst within 30 to 60 seconds. The headache usually begins to subside within an hour of the worst pain, but it can last for a week or longer.
If you experience repeated attacks, you should see a doctor immediately.
Causes of thunderclap headache
The exact cause of thunderclap headaches is unknown, but in some cases, they may be caused by life-threatening conditions such as:
- Bleeding between the brain and the membranes covering it
- Ruptured blood vessels in the brain
- Tear in the artery layer that supplies blood to the brain
- Cerebrospinal fluid leaks due to a tear in the layer around the nerve roots in the spinal cord
- Tissue death or bleeding in the pituitary gland
- Blood clots in the brain
- Severe increase in blood pressure
- Infections such as meningitis or encephalitis
- Ischemic stroke
Treatment for thunderclap headache
Before determining treatment, a doctor needs to perform an examination to identify the cause. In addition to a physical exam, the doctor may recommend a CT scan or other tests such as MRI and spinal tap to help determine the cause.
Based on the results of the examination, the doctor may prescribe treatment such as:
- Surgery to repair tears or blockages
- Medications to control blood pressure
- Pain relief medications to manage the headache
Thunderclap headaches require immediate treatment. Delaying medical attention can be life-threatening if the headache is caused by brain bleeding.
If you suffer from migraines on a regular basis, whether you know what causes them or not, seek medical attention right away. If you have unusual headaches, consult with a doctor.
