Orthostatic headache
Orthostatic headache is a medical condition in which a person develops a headache while vertical and the headache is relieved when horizontal.[1][2]
Causes
The most common cause of orthostatic headache is low cerebrospinal fluid pressure, due to a spontaneous cerebrospinal fluid leak, a traumatic cerebrospinal fluid leak, or a post-dural-puncture leak.[3] It is also occasionally the most prominent symptom of postural orthostatic tachycardia syndrome (POTS).[4] Distinguishing POTS from a cerebrospinal fluid leak can be difficult, because the defining symptom of POTS, positional tachycardia, also occurs in some people with cerebrospinal fluid leaks.[4] Furthermore, both POTS and cerebrospinal fluid leaks are sometimes present in the same person, especially in people with Ehlers–Danlos syndrome.[4]
Other causes include colloid cysts and possibly connective tissue disorders.[5] It may occur as a complication of decompressive surgery for Chiari malformation or decompressive craniectomies for cerebral edema.[5]
