Abstract
BACKGROUND Nummular headache and epicrania fugax are two primary headaches that fall under the heading of epicranial headaches. METHODS This article reviews the epidemiological and clinical features of nummular headache and epicrania fugax, proposed pathogenic mechanisms and state-of-the-art management, according to the literature. RESULTS AND CONCLUSIONS Nummular headache and epicrania fugax are generally viewed as rare headache disorders, but no population-based epidemiological data are available. Nummular headache is characterized by continuous or intermittent head pain, which remains circumscribed in a round or oval area of the scalp, typically one to six centimeters in diameter. Epicrania fugax manifests with brief paroxysms of pain that move along the surface of the head, following a linear or zigzag trajectory through different nerve territories. Nummular headache and epicrania fugax are mostly primary headaches, but some secondary cases have been reported. The pathogenesis of these headaches is not fully understood. Nummular headache could probably originate in epicranial tissues or adjacent intracranial structures, while the origin of epicrania fugax could be extracranial or intracranial. Diagnostic assessment requires careful examination of the symptomatic areas. Underlying disorders should be excluded by additional investigations, including neuroimaging and appropriate blood tests. No controlled clinical trials have been conducted in nummular headache or epicrania fugax. Analgesics and anti-inflammatory drugs, botulinum toxin and gabapentin are currently the most recommended treatment options for nummular headache. In epicrania fugax, the most used treatments are gabapentin, lamotrigine, and other antiseizure medications.

Abstract
Background Other primary headaches make up group 4.0 of the International Classification of Headache Disorders third edition (ICHD-3). This group includes a clinically varied group of headache entities whose pathophysiology is not well understood and whose treatments are based on open-label reports. Objective To review and update the uncommon primary headaches included under group 4.0 in ICHD-3. Methods We reviewed the headache disorders listed under group 4.0 of ICHD-3 for the clinical features, diagnostic criteria, and management, and described recent updates of these relatively rare disorders. Results The entities included in this group have a characteristic presentation in practice. Some of them are activity-related and can be provoked by Valsalva maneuver (primary cough headache), some by prolonged exercise (primary exercise headache), and some by sexual excitation (primary headache associated with sexual activity); primary thunderclap headache has also been included here because all the above-listed entities can sometimes present in thunderclap fashion too. Two of the entities in this group 4.0 are linked to direct physical stimuli viz. cold stimulus headache and external pressure headache. Also included in this group are primary stabbing headaches and nummular headaches that are presumed to be due to the involvement of the terminal branches of the sensory nerves supplying the scalp and are, therefore, termed "epicranial headaches." Hypnic headache syndrome and new daily persistent headache are included here as "miscellaneous headaches" because we still do not know enough about their causation. Conclusion The headache disorders included under group 4.0 in ICHD-3 are uncommon, heterogeneous entities, which may pose diagnostic and management challenges to the physicians. The diagnosis may be missed owing to a lack of familiarity.

Abstract
PURPOSE OF REVIEW The purpose of this manuscript is to shed light on systematic work-up of a diagnostic challenge such as nummular headache (NH), and to summarize the relevant literature on NH. RECENT FINDINGS The specific nature of the shape of the pain site is usually characteristic of NH. Multiple modalities of investigation including succinct imaging are necessary to successfully rule out other similar conditions. A 26-year-old female patient of Asian-Indian origin presented to the clinic with the chief complaint of chronic persistent left parietal headache for more than 10 years, which has been worsening over the past few days with no specific identifiable trigger. The diagnosis of nummular headache is challenging and confusing due to the rare occurrence and inadequate references in the literature. Appropriate imaging was done, which revealed no pathology that could explain the headache presentation. These findings are consistent with our diagnosis of nummular headache, and helped in the successful management of the case.

Abstract
Nummular headache (NH) is an uncommon primary headache characterized by pain limited to a precise small area of the scalp. There is no global consensus on its pathogenesis, but its extracranial origin is the most accepted theory. Moreover, peripheral mechanism is supported by the overlapping symptomatology of secondary forms of NH and is well described in the literature. However, a standard effective treatment is still lacking. METHODS A literature search according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was conducted to evaluate surgical strategies for NH. Inclusion criteria were English language, diagnosis of primary NH according to International Classification of Headache Disorders, 3rd Edition, or of secondary NH, and follow-up at a minimum of 3 months. The treatment had to consist of peripheral surgery. RESULTS One hundred eighty-seven records were identified after duplicates were removed, 15 full-text articles were assessed for eligibility, and 4 records were selected for inclusion. A total of 53 patients were included in this review, 50 of whom were diagnosed with primary NH. The general positive response after surgery (>50% reduction in occipital migraine headaches) was about 70.0% for primary NH, while secondary NH always showed complete pain relief. However, many variations in patient selection and type of surgery were described. CONCLUSIONS Neurovascular relationship in the extracranial tissues seems to be involved in the onset of NH. However, only limited data from meager literature and from few patients are currently available. Shared multicentric research protocols are badly required.

Abstract
BACKGROUND/OBJECTIVE Nummular headache (NH) is a primary headache disorder characterised by intermittent or continuous scalp pain, affecting a small circumscribed area of the scalp. As there are limited data in the literature on NH, we conducted this review to evaluate demographic characteristics and factors associated with complete resolution of the headache, and effectiveness of treatment options. METHODS We performed a systematic review of cases reported through PubMed database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and 'nummular headache', 'coin-shaped headache' and 'coin-shaped cephalalgia' keywords. Analysis was performed by using χ2 test and Wilcoxon rank-sum test. For individual interventions, the response rate (RR%) of the treatment was calculated. RESULTS We analysed a total of 110 NH cases, with median age 47 years and age of pain onset 42 years. Median duration to make correct diagnosis was 18 months after first attack. The median intensity of each attack was 5/10 on verbal rating scale over 4 cm diameter with duration of attack <30 min. Patients with NH had median three attacks per day with frequency of 9.5 days per month. 40 (57.97%) patients had complete resolution of the headache after treatment. Patients with complete resolution were younger, more likely to be female, and were more likely to have diagnosis within year. Patients with complete resolution more likely to have received treatment with onabotulinum toxin A (botulinum toxin type A (BoNT-A)), and gabapentin compared with patients without complete resolution. Most effective interventions were gabapentin (n=34; RR=67.7%), non-steroidal anti-inflammatory drugs (NSAIDs) (n=32; RR=65.6%), BoNT-A (n=12; RR=100%) and tricyclic antidepressant (n=9; RR=44.4%). CONCLUSION Younger patients, female sex and early diagnosis were associated with complete resolution. NSAIDs, gabapentin and BoNT-A were most commonly used medications, with significant RRs.

Abstract
PURPOSE OF REVIEW Unusual headache disorders are less commonly discussed and may be misdiagnosed. These headache disorders frequently have a benign natural history; however, without reassurance, therapeutic education, and treatment, they can negatively affect the health and function of patients. RECENT FINDINGS This article reviews the clinical features, diagnosis, workup, and proposed treatments for several unusual headache disorders including primary cough headache, primary headache associated with sexual activity, primary exercise headache, cold-stimulus headache, primary stabbing headache, nummular headache, hypnic headache, and headache attributed to travel in space. Exploding head syndrome is also discussed, which is a sleep disorder commonly confused with a headache disorder. SUMMARY Unusual headache disorders are usually benign, yet without the correct diagnosis can be very worrisome for many patients. Through greater awareness of these headache disorders, neurologists can evaluate and effectively manage unusual headache disorders, which offers significant benefits to patients and practice satisfaction to neurologists.

Abstract
Migraine and other chronic headache disorders are common and if inadequately treated, can lead to significant disability. The effectiveness of medications can be limited by side effects, drug interactions, and comorbid diseases necessitating alternative methods. Technological developments in the past 5 years have made it possible to use non-invasive methods of neuromodulation to treat primary headache disorders. This field includes technologies such as supraorbital transcutaneous stimulation (STS), transcranial magnetic stimulation (TMS), and non-invasive vagal nerve stimulation (nVNS). Existing trials show these modalities are safe and well tolerated and can be combined with standard pharmacotherapy. We review the technologies, biological rationales, and trials involving non-invasive neuromodulation for the treatment of primary headache disorders.

Abstract
Background Nummular headache, or coin-shaped cephalagia, is defined as a mild to moderate, pressure-like pain that is felt exclusively in a circumscribed area. More than 200 cases of nummular headache have been reported since it was defined in 2002, but the pathogenesis remains unclear. Methods A patient with nummular headache who had the symptomatic area of his scalp removed but suffered headache reappearance was reported. All published cases of nummular headache in the English literature were reviewed and analyzed for demographic and clinical features, image and laboratory findings, and response to treatment. Results The patient with nummular headache had the symptomatic area of the scalp removed but suffered reappearance of headache in another area that overlapped with the former one. The literature review showed that nummular headache was a chronic, mild to severe, pressure-like pain with a circular or elliptical shape of 1–10 cm in diameter. The parietal region was the most affected region. Exacerbations and sensory disturbances in the affected area were reported in 43% and 56% of cases, respectively. Observational data suggested botulinum toxin type A (BoNTA) and gabapentin may be beneficial. Discussion Our case and evidence from the literature review support the peripheral mechanism of nummular headache. Nummular headache might be a local pain disorder stemming from terminal branches of a sensory nerve and could induce peripheral sensitization in one or several primary sensory neurons.

Abstract
Objectives: Apart from the characteristic chronic head pain in a coin-shaped circumscribed area, superimposed exacerbations have been described from early reports of nummular headache (NH). In a prospective series, we aim to compare the demographic and clinical characteristics between cases of exacerbations (ENH) and non-exacerbations (NENH) in NH. Methods and results: Seventy-two NH patients (44 female, 28 male) attending a headache outpatient office. As eight patients presented with bifocal NH we analysed 80 painful areas; 47 (58.8%) presented in situ exacerbations. Mean intensity of exacerbations was 7.5 ± 1.6 and they lasted 5.7 ± 11.6 minutes. Exacerbation quality was mostly stabbing. We found no differences between ENH and NEHN groups in age at onset, baseline pain intensity, size of painful area, allodynia or other sensory symptoms, or baseline pain quality. There were no differences between populations with respect to relief with symptomatic therapy, requirement of preventative therapy and its response to preventatives. Conclusion: In situ exacerbations superimposed on baseline pain are frequent in NH and might be included in diagnostic criteria. No statistically significant differences were found between ENH and NENH cases in demographic and nosological characteristics, or needing or response to therapy, but these sample sizes are small.

Abstract
Nummular headache (NH) is characterized by focal pain fixed within a small round or elliptical area of the head surface. Sensory dysfunction is apparently restricted to the symptomatic area, but a thorough analysis of cranial pain sensitivity has not been performed. Pressure pain sensitivity maps were constructed for 21 patients with NH and 21 matched healthy controls. In each subject pressure pain thresholds (PPT) were measured on 21 points distributed over the scalp. In each patient PPT were also measured in the symptomatic area and at a non-symptomatic symmetrical point. In both groups an anterior to posterior gradient was found on each side, with no significant differences of PPT measurements between sides or groups. In patients with NH, only the symptomatic area showed a local decrease of PPT (significant in comparison with the non-symptomatic symmetrical point, P < 0.001). These findings further support that NH is a non-generalized disorder with a peripheral source.
