A thunderclap headache is a headache that is severe and sudden-onset. It is defined as a severe headache that takes seconds to minutes to reach maximum intensity. It can be indicative of a number of medical problems, most importantly subarachnoid hemorrhage, which can be potentially life-threatening. Usually, further investigations are performed to identify the underlying cause.
Sign and symptom
A headache is called "thunderclap headache" if it is severe in character and reaches maximum severity within seconds to minutes of onset. In many cases, there are no other abnormalities, but the various causes of thunderclap headaches may lead to a number of neurological symptoms. The most important causes are subarachnoid hemorrhage, cerebral venous sinus thrombosis and cervical artery dissection.
- Syncope, seizure, visual symptom, vomiting
- Meningism (Kernig’s sign and Brudzinki’s sign)
- Decreased level of consciousness
- Typically persists for several days
Other causes of thunderclap headache
- Subarachnoid hemorrhage (10%-25% of all cases of thunderclap headache)
- Cerebral venous sinus thrombosis
