Primary cough headache, primary exertional headache, and primary headache associated with sexual activity

Update on primary headache associated with sexual activity and primary thunderclap headache

BACKGROUND

This narrative review aims to provide an update on primary headache associated with sexual activity and primary thunderclap headache.

METHODS

We conducted a literature search on PubMed with the keywords "headache associated with sexual activity", "sexual headache", "orgasmic cephalalgia", and "coital cephalalgia" in addition to "thunderclap headache" to assess the appropriateness of all published articles in this review.

RESULTS

Primary headache associated with sexual activity is a "primary" headache precipitated by sexual activity, which occurs as sexual excitement increases (progressive at onset), or manifests as an abrupt and intense headache upon orgasm (thunderclap at onset) or combines these above two features. Primary headache associated with sexual activity is diagnosed after a thorough investigation, including appropriate neuroimaging studies, to exclude life-threatening secondary causes such as subarachnoid hemorrhage. According to the criteria of the third edition of the International Classification of Headache Disorders, primary thunderclap headache is also a diagnosis by exclusion. The pathophysiology of primary headache associated with sexual activity and primary thunderclap headache remains incompletely understood. Treatment may not be necessary for all patients since some patients with primary headache associated with sexual activity and primary thunderclap headache have a self-limiting course.

CONCLUSION

A comprehensive neuroimaging study is needed for distinguishing primary headache associated with sexual activity or primary thunderclap headache from secondary causes. Primary headache associated with sexual activity and primary thunderclap headache are self-limited diseases and the prognoses are good, but some patients with primary headache associated with sexual activity may have a prolonged course.

Headache Associated with Sexual Activity-A Narrative Review of Literature

Headache associated with sexual activity (HAWSA) has accompanied humanity since ancient times. However, it is only since the 1970s that it has become the subject of more extensive and detailed scientific interest. The purpose of this review is to provide an overview of the development of the concept of HAWSA, its clinical presentation, etiopathogenesis, diagnosis and treatment especially from the research perspective of the last 20 years. Primary HAWSA is a benign condition, whose etiology is unknown; however, at the first occurrence of headache associated with sexual activity, it is necessary to exclude conditions that are usually immediately life-threatening. Migraine, hypnic headache or hemicrania continua have been reported to co-occur with HAWSA, but their common pathophysiologic basis is still unknown. Recent advances in the treatment of HAWSA include the introduction of topiramate, progesterone, and treatments such as greater occipital nerve injection, arterial embolization, and manual therapy. Whether these new therapeutic options will stand the test of time remains to be seen.

Paroxysmal pressing headache: A new short-lasting headache

INTRODUCTION

In this report we describe a series of patients with a previously undescribed headache.

METHODS

Over a 4-year period, we recruited 14 patients with a distinctive type of head pain of unknown cause that did not meet diagnostic criteria for other primary headaches.

RESULTS

Nine women and five men with a mean age of 49.6 years (standard deviation, 17.8) presented with spontaneous headache attacks lasting 2-15 minutes. In each attack, the pain was localized to a region of one side of the head. Pain location varied between episodes in 12 patients. Pain quality was pressing, and pain intensity was mild to severe. There were no accompanying symptoms. Physical examination and all ancillary tests were unremarkable. Among seven patients who tried pharmacological treatments, one responded to antidepressants, another to indomethacin and three to other nonsteroidal anti-inflammatory drugs or simple analgesics.

CONCLUSIONS

Paroxysmal pressing headache may be a new headache syndrome marked by short duration of the pain and shifting location.

Laugh-Induced Headache: Clinical Features and Literature Review

BACKGROUND

Laughing is a rare precipitating factor for headaches, and the pathogenesis underlying laugh-induced headache (LH) remains unclear.

METHODS

Two cases of headache triggered predominantly by laughing were presented in this article. We also reviewed the published English literature regarding LH, summarized the clinical characteristics of LH, and discussed the probable pathophysiological mechanisms.

RESULTS

In the first patient, magnetic resonance imaging of the brain revealed cerebellar tonsillar herniation through the foramen magnum. In the second patient, we did not find any evidence of intracranial disease. The literature review showed that LH is a mild to severe, non-pulsating headache. In most cases, the duration of each attack was limited to a few minutes. The headache usually bursts after laughing and reaches its peak almost immediately. In some cases, the headache can only be induced by mirthful laughing rather than by fake laughing.

CONCLUSION

LH can be categorized as primary LH and secondary LH. Changes in the spatial structure in the posterior cranial fossa and cerebrospinal fluid circulation may contribute to the development of secondary LH. Primary LH, primary cough headache, and primary exercise headache may share some common pathogenesis. And we speculate that the regions of the brain associated with the expression of mirth might be associated with LH.

[Different headache forms of chapter 4 of the International Headache Classification]

Chapter 4 of the International Classification of Headaches contains a group of clinically very heterogeneous primary headache forms. Little is known about the pathogenesis of these headache types and therapy is usually based on isolated case reports and uncontrolled studies. The forms include primary stabbing headache, primary cough headache, primary exertional headache, primary headache associated with sexual activity, hypnic headache, primary thunderclap headache, hemicrania continua and the new daily persistent headache. Some of these headache forms may be of a symptomatic nature and require careful examination, imaging and further tests. Primary and secondary headache forms must be carefully distinguished.
