What Is a Thunderclap Headache?

A thunderclap headache is a type of headache that comes suddenly and usually severe.

Some of the thunderclap headaches can also last for more than a week. Some medical experts consider a thunderclap headache as sign of a serious medical emergency. Immediate medical attention is usually recommended.

Causes of thunderclap

A thunderclap headache can suddenly occur without any obvious reason . In some cases, it can be a result of some potentially life threatening condition. One of them is a bleeding occurring between the brain and the membranes that cover it. A thunderclap headache can also be caused by a bulge in the blood vessel with the risk of rupturing.

A tear in the artery that supplies the blood into the brain may also cause a thunderclap headache. A cyst that may be blocking cerebrospinal fluid flow may also cause such headaches as well as bleeding in the pituitary gland. Certain infections such as those leading to meningitis or encephalitis may also cause thunderclap headaches.
