Doctors often find diagnosing a thunderclap headache challenging. Although such headaches often signal a serious underlying medical condition, sometimes the cause can be relatively benign.
Some accompanying symptoms that may signal a serious underlying medical condition include:
- confusion or change in consciousness
- fever
- weakness
- visual disturbances
- difficulty thinking or speaking
- unusual sensations
if a thunderclap headache is an early symptom of an underlying medical condition, a person may not have any other symptoms. To help with diagnosis, a doctor may use medical imaging such as a head CT scan or MRI.
Certain activities may trigger a thunderclap headache in some people. Examples of such activities include:
- physical activity

Whether it is possible to reduce the risk of a thunderclap headache depends on its cause. Some general tips to reduce the risk of underlying conditions that may cause a thunderclap headache include:

The following types of headache can cause pain of a similar severity to thunderclap headaches. However, unlike thunderclap headaches, their causes are usually less serious.
- Ice pick headaches: Headaches that involve brief stabbing pains in the front or side of the head.
- Migraines: Headaches that involve a severe throbbing or pulsing ache on one side of the head. These can occur alongside other symptoms, such as nausea and vomiting.
- Cluster headaches: Severe headaches that occur quickly, usually around the front of the head or face. They typically cause problems with one eye, such as watering. Like thunderclap headaches, they tend to have a rapid onset.

Anyone who experiences a thunderclap headache should, therefore, seek urgent medical attention.
The outlook for a thunderclap headache depends entirely on its cause.
In some cases, there is no apparent cause, and the headache may never happen again. In other cases, it could be the result of a recurring headache disorder.
In the most severe cases, thunderclap headaches may be due to a serious underlying medical condition, such as subarachnoid hemorrhage or a stroke. The outlook in these cases will depend on various factors, including the extent of the brain damage, and the person’s overall health.
