Extremely Dangerous - Thunderclap headache - Netflix

A thunderclap headache, also referred to as a lone acute severe 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. Although approximately 75% are attributed to “primary” headaches—headache disorder, non-specific headache, idiopathic thunderclap headache, or uncertain headache disorder—the remainder are secondary to other causes, which can include some extremely dangerous acute conditions, as well as infections and various other conditions. Usually, further investigations are performed to identify the underlying cause.
