Thunderclap headache: an update

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.

Towards a pituitary apoplexy classification based on clinical presentation and patient journey

PURPOSE

The condition of pituitary apoplexia contains the clinical spectre from life-threatening emergency to asymptomatic self-limiting course, which partly determines diagnostic delay and management. Outcome evaluation of course and management of pituitary apoplexia is hampered by the diverse presentation of this condition and requires appraisal. This study aimed to describe the patient journey, clinical presentation, and management of various types of pituitary apoplexy in a new classification to facilitate future outcome evaluation and identify unmet needs in the care process.

METHODS

A single-center retrospective patient chart study was conducted between 2005-2021 (N = 98). Outcome measures were clinical symptoms at first presentation in hospital, being headache, consciousness, visual acuity, visual field defects (VFD), ophthalmoplegia, nausea, vomiting, fever, and hypopituitarism and care process characteristics.

RESULTS

Mean age was 47.6 ± 16.6 years (51.0% male). We describe their patient journey and identified three different types, differing in clinical presentation, in-hospital route, and final treatment, e.g., Acute (type A, 52%), Subacute (type B, 22.5%), and Non-acute (type C, 25.5%). Type A generally presents with acute onset headaches, VFD, or ophthalmoplegia emergency setting, with lowest mean visual acuity of both eyes and frequent hypocortisolism.

CONCLUSIONS

Pituitary apoplexy can be approached as a spectrum of disease with 3 main subtypes, with a different initial presentation, different in-hospital route resulting in different management. Acknowledging subtypes with particular needs for (emergency) referrals to Pituitary Tumors Center of Excellence (PTCOE) will serve patient care improvements, outcome evaluations and address areas for improvement.

Reversible cerebral vasoconstriction syndrome in children: an update

Headaches are one of the most common neurologic complaints leading to emergency room visits in pediatric patients. Of the different type of headache presentations, thunderclap headaches require a particularly urgent work-up. In children, recurrent thunderclap headaches are more often associated with reversible cerebral vasoconstriction syndrome (RCVS) than other etiologies such as subarachnoid hemorrhage. RCVS is a vascular disorder of incompletely understood etiology, characterized by diffuse vasoconstriction of the cerebral arterial vasculature, and commonly associated with recurrent severe headaches. Patients may experience focal neurological deficits, due to hemorrhages, infarcts, and even posterior reversible encephalopathy syndrome . Although RCVS has been best characterized in adults, it does occur in children. This review summarizes the presentation of RCVS in children and highlights some of the differences with the adult population.

Diagnosing Secondary and Primary Headache Disorders

PURPOSE OF REVIEW

This article provides a systematic diagnostic approach to the patient with headache.

RECENT FINDINGS

The vast majority of patients presenting with headache in clinical practice have a primary headache disorder. The most common primary headache disorder in clinical practice is overwhelmingly migraine. Unfortunately, a substantial proportion of patients with migraine do not receive an accurate diagnosis. In addition, the clinical features of migraine overlap with secondary causes of headache, making a careful history and deliberative evaluation for warning symptoms or signs of a secondary headache disorder of paramount importance.

SUMMARY

The approach to the patient with headache requires knowledge of the diagnostic criteria for primary headache disorders, recognition of the importance of a systematic evaluation for red flags associated with secondary headache disorders, and awareness of the pearls and pitfalls encountered in the diagnostic evaluation of a patient with headache.

Severe abrupt (thunderclap) non-traumatic headache at the pediatric emergency department - a retrospective study

BACKGROUND

Adult abrupt severe non-traumatic headache (thunderclap) is often related to serious underlying etiologies such as subarachnoid hemorrhage. However, data are sparse regarding thunderclap headache in the pediatric population.

OBJECTIVE

The aim of the study was to evaluate the prevalence, characteristics and causes of thunderclap headache in the pediatric and adolescent population, aged 6-18 years, presenting to a pediatric emergency department.

METHODS

The electronic database of a tertiary care pediatric emergency department was searched for children presenting with acute headache during 2016-2018. Headache severity was defined by pain scales, either a visual analogue scale or by the Faces Pain Scale-Revised.

RESULTS

Thunderclap headache was diagnosed in 19/2290 (0.8%) of the included patients, all of them with a pain score of 10/10. All the patients had a benign course. Primary headache was diagnosed in 15/19 (78.9%), six patients had migraine and eight were diagnosed with primary thunderclap headache. Four of the 19 patients were diagnosed with secondary headache: three with infectious causes and one with malignant hypertension.

CONCLUSIONS

Thunderclap headache is rare among children and adolescents presenting to the emergency department. This headache is generally of a primary origin. Extensive evaluation is still needed to rule out severe diagnosis problems.

[Headache and cerebrovascular diseases]

Headache is a common symptom of acute and chronic cerebrovascular diseases. Headache can be symptomatic in patients with various forms of vascular pathology of the brain but primary headaches are much more common. Secondary headaches in acute cerebrovascular accidents may be the first symptom, and in some cases, a risk factor or complication of stroke. In chronic cerebrovascular diseases, headache may be the predominant symptom in the early stages and resolve in the later stages of the disease. At the same time, the severity, nature and course of headache cannot be considered as reliable signs of cerebrovascular disease. Meanwhile, the verification of the headache form is important from the point of view of determining the priorities of diagnosis and therapy.

Pituitary haemorrhage and infarction: the spectrum of disease

BACKGROUND

Pituitary apoplexy is an acute syndrome of haemorrhage or infarction into the pituitary. The condition is relatively well-described. Less well-described is sub-acute presentation of the same condition.

OBJECTIVE

To compare the clinical presentation and natural history of subacute pituitary haemorrhage/infarction with pituitary apoplexy (acute).

METHOD

Retrospective analysis of a consecutive cohort of 55 patients (33 with pituitary apoplexy, 22 with subacute disease) presenting to University Hospital Plymouth between 1994 and 2019. Comparison of the clinical, endocrinological and radiological features at presentation. Comparison of clinical treatment and subsequent outcomes for the two groups.

RESULTS

There were no significant differences in predisposing factors for the two groups. Acute headache was more frequent in the acute group. Chronic headache was common in both groups prior to presentation. Low sodium was more common at presentation in the acute group (11/26 vs 2/19 P = 0.02) otherwise there were no differences in endocrine deficit at presentation. A significant proportion showed an improvement in endocrine function at follow up (acute 8/31, subacute 5/21 P = 1.0). MRI characteristics were variable at presentation and follow up in both groups. Ring enhancement with contrast was more frequent in acute (14/20 vs 3/11 P = 0.03). This appearance resolved at follow up in the majority.

CONCLUSIONS

Pituitary apoplexy has a characteristic and dramatic presentation. Subacute pituitary haemorrhage/infarction shows similar natural history and outcome. These conditions would appear to represent a spectrum of the same condition.

Vessel-wall MRI in thunderclap headache: A useful tool to answer the riddle?

BACKGROUND

Finding an intracranial aneurysm (IA) during a thunderclap headache (TCH) attack, represents a problem because it is necessary to distinguish whether the aneurysm is responsible for the headache as a warning leak or as an incidental finding. High-Resolution Vessel-Wall (HRVW) MRI sequences have been proposed to assess the stability of the wall, as it permits to detect the presence of aneurysmal wall enhancement (AWE). In fact, AWE has been confirmed due to inflammation, recognizable preceding rupture.Case 1: A 37-year-old woman with a migraine more intense than her usual. A CTA revealed a 10 mm AComA aneurysm without subarachnoid hemorrhage (SAH) and HRVW-MRI excluded AWE. The patient's headache improved, and therefore, the aneurysm was considered an incidental finding, and the headache diagnosed as TCH attack. Subsequently, the aneurysm was surgically clipped, and typical migraine relapsed was reported at follow-up (FU).Case 2: A 67-year-old woman with no history of headaches underwent CTA for an abrupt onset of headache. A 7 mm right carotid-ophthalmic aneurysm with no sign of SAH was discovered. HRVW-MRI demonstrated AWE and thus, a TCH attack for a warning leak of an unstable wall was suspected. Endovascular coiling was immediately performed and at FU any further headache attack was reported.

CONCLUSIONS

HRVW-MRI is useful in case of finding aneurysm as the cause of headaches, particularly the TCH attack. In fact, HRVW-MRI could assess the stability of the aneurysms wall, allowing different patient management and eventually the aneurysmal treatment.
