Review
Paroxysmal hemicrania and hemicrania continua are indometacin-sensitive trigeminal autonomic cephalalgias, a terminology which reflects the predominant distribution of the pain, observable cranial autonomic features and shared pathophysiology. Understanding the latter is limited, both by low prevalence and the intricacies of studying brain function, requiring multimodal techniques to glean insights into such disorders. Similarly obscure is the curious response to indometacin. This review will address what is currently known about pathophysiology, the rationale for the current classification and, features which may confound the diagnosis, such as lack of cranial autonomic symptoms and those which are typically associated with migraine such as nausea, photophobia, phonophobia and aura. Despite these characteristics, a dramatic response to indometacin, which is not seen in migraine nor the other trigeminal autonomic cephalalgias , provides the hallmark of the diagnosis. The main clinical differential for paroxysmal hemicrania is based on temporal pattern and lies between cluster headache and short-lasting-neuralgiform headache attacks with tearing or additional cranial autonomic symptoms. For hemicrania continua it is more challenging as the main differential for which the disorder is often treated is migraine. A prior episodic pattern, often days at a time, and the tendency to exacerbation with analgesics will further deflect from the diagnosis. The relevance of this is that there is little overlap in therapeutics between paroxysmal hemicrania and hemicrania continua and other headache disorders and there are limited effective alternatives to indometacin. The most effective are other non-steroidal anti-inflammatory drugs including the newer COX-II inhibitors. Even though early reports suggest that a higher indometacin dose-requirement may herald a secondary precipitating pathology, this does not seem to be the case, with syndrome and response to treatment being similar with the primary disorder. In this context imaging of new onset paroxysmal hemicrania or hemicrania continua and implication of the results will be discussed as will alternative treatment options.

OBJECTIVES
The objective of this study was to investigate auditory hypersensitivity in WS and to evaluate hyperacusis through standardized protocols, checking if it can be associated with the absence of acoustic reflexes in people with WS.
METHOD
The study was performed in 17 individuals with WS, aged between seven and 17 years old (10 males and seven females), and 17 individuals with typical development age- and gender-matched to individuals with WS. Statistical tests were used to analyze the responses collected with the Loudness Discomfort Level (LDL) test as well as ipsilateral and contralateral reflex responses.
RESULTS
Auditory hypersensitivity was commonly found. Individuals with WS had phonophobia and were less tolerant to high sound intensity, presenting a reduced discomfort threshold compared to those with typical development. However, hyperacusis was found in 35.29% of individuals with WS and was mild in 50% of cases. There was an association between hyperacusis and acoustic reflex responses, and individuals with absence of the contralateral acoustic reflex were more likely to have hyperacusis.
CONCLUSIONS
Individuals with WS have a high prevalence of auditory hypersensitivity, with the presence of phonophobia; however, hyperacusis was not as prevalent and may be associated with the absence of contralateral acoustic reflexes.

Many individuals with tinnitus report experiencing hyperacusis (enhanced sensitivity to sounds). However, estimates of the association between hyperacusis and tinnitus is lacking. Here, we investigate this relationship in a Swedish study. A total of 3645 participants (1984 with tinnitus and 1661 without tinnitus) were enrolled via LifeGene, a study from the general Swedish population, aged 18-90 years, and provided information on socio-demographic characteristics, as well as presence of hyperacusis and its severity. Tinnitus presence and severity were self-reported or assessed using the Tinnitus Handicap Inventory (THI). Phenotypes of tinnitus with ( = 1388) or without ( = 1044) hyperacusis were also compared. Of 1661 participants without tinnitus, 1098 (66.1%) were women and 563 were men (33.9%), and the mean (SD) age was 45.1 (12.9). Of 1984 participants with tinnitus, 1034 (52.1%) were women and 950 (47.9%) were men, and the mean (SD) age was 47.7 (14.0) years. Hyperacusis was associated with any tinnitus [Odds ratio (OR) 3.51, 95% confidence interval (CI) 2.99-4.13], self-reported severe tinnitus (OR 7.43, 95% CI 5.06-10.9), and THI ≥ 58 (OR 12.1, 95% CI 7.06-20.6). The association with THI ≥ 58 was greater with increasing severity of hyperacusis, the ORs being 8.15 (95% CI 4.68-14.2) for moderate and 77.4 (95% CI 35.0-171.3) for severe hyperacusis. No difference between sexes was observed in the association between hyperacusis and tinnitus. The occurrence of hyperacusis in severe tinnitus is as high as 80%, showing a very tight relationship. Discriminating the pathophysiological mechanisms between the two conditions in cases of severe tinnitus will be challenging, and optimized study designs are necessary to better understand the mechanisms behind the strong relationship between hyperacusis and tinnitus.

Review
PURPOSE OF REVIEW
Post-COVID headache may be unique in presentation and mechanism, often presenting as a new phenotype in patients with a history of a primary headache disorder or resulting in a new headache syndrome in those without history of headache. This review presents a description of the literature published focused on post-COVID headache. Additionally, we discuss potential mechanisms and considerations for treatment of post-COVID headache.
RECENT FINDINGS
Headache is one of the most common symptoms of COVID. Common characteristics are revealed when reviewing the phenotypes of headaches that have been described in patients with COVID-19, with most headache phenotypes resembling migraine and new persistent daily headache. Post-COVID headaches are often described as moderate to severe, persistent, and treatment refractory. This review highlights the diversity of presentation of headaches that present as a complication of COVID-19. Treatment of post-COVID headache is challenging, especially in the setting of a pandemic where resources are limited.
CLINICAL CASE
A 42-year-old woman with a history of episodic migraine without aura presents over video visit with a new headache type. Her typical headaches are predominantly left sided, throbbing in nature, and associated with photophobia and phonophobia. They are fully relieved by oral sumatriptan 2 h after treatment. She describes this new headache as a constant, pulsating, holocephalic pain with no other migrainous features that have been ongoing for 6 weeks. She notes that the headache has been persistent since that time. She has tried over-the-counter acetaminophen and ibuprofen and her typical migraine abortive therapy without relief. She is debilitated and wonders if there is anything that will take the pain away. She shares that she tested positive for COVID-19 about 2 days prior to headache onset and has associated rhinorrhea, anosmia, and ageusia.

Review
Superior canal dehiscence syndrome (SCDS) is a vestibular disorder in which the presence of a pathological third window in the labyrinth causes several vestibular and cochlear symptoms. Herein, we review the diagnostic criteria and treatment of SCDS. The cause of SCDS is considered to be congenital or acquired; however, its etiology is not well known. Symptoms: Vertigo and/or oscillopsia induced by loud sounds (Tullio phenomenon) or stimuli that change the middle ear or intracranial pressure (fistula symptoms) with vestibular symptoms and hyperacusis and aural fullness with cochlear symptoms are characteristic clinical complaints of this syndrome. Neurological tests: Vertical-torsional eye movements can be observed when the Tullio phenomenon or fistula symptoms are induced. Conductive hearing loss with both a decrease in the bone conduction threshold at lower frequencies and an increase in the air conduction threshold at lower frequencies may be present on audiometry. Cervical and/or ocular vestibular evoked myogenic potentials are effective in strongly suspecting the presence of a pathologic third window in the labyrinth. Computed tomography (CT) imaging: High-resolution CT findings with multiplanar reconstruction in the plane of the superior semicircular canal consistent with dehiscence indicate SCDS. The Pöschl view along the plane of the superior semicircular canal and the Stenvers view perpendicular to it are recommended as CT imaging conditions. Findings from all three major diagnostic categories (symptoms, neurological tests, and/or CT imaging) are needed to diagnose SCDS. The surgical approaches for SCDS are as follows: the 1) middle cranial fossa approach, 2) transmastoid approach, and 3) round window and oval window reinforcement. Each technique has advantages and disadvantages.

AIM
Given the similar presentation of migraine aura and acute ischemic stroke, advancing patient age might change the characteristics of migraine with aura (MA) and be clinically important. Clinical data, however, are limited. Experimental studies indicate a decrease in the magnitude of cortical spreading depression (CSD), the pathophysiological correlate of migraine aura, with advancing age. Our study aimed to assess the influence of age on the clinical features of MA.
METHODS
Three hundred and forty-three patients were interviewed using a structured questionnaire. The questions covered the headache characteristics and symptom types including the characteristics of the C-criterion, as defined by the International Classification of Headache Disorders 3 Edition. The association of age with MA characteristics was assessed.
RESULTS
The median age was 29 (IQR 28-52) and 235 of the 343 patients were women (69%). Individual symptoms of the C-criterion such as gradual aura spreading over longer than 5 min (P < 0.001), two or more aura symptoms occurring in succession (P = 0.005), duration of at least one MA symptom for longer than 60 min (P = 0.004), and associated headache (P = 0.01) were more frequent in younger patients. The number of symptoms including the C-characteristics decreased with increasing age (P < 0.001). Patients with sensory (P < 0.001), motor (P = 0.004) and speech disturbance (P = 0.02) were younger, and older patients with headache had less photophobia (P = 0.04) and phonophobia (P = 0.03). Sensitivity analyses yielded similar results.
CONCLUSION
The frequency of typical characteristics of migraine aura and migraine headache including photophobia and phonophobia decreases with advancing patient age. This might have potentially difficult implications for the diagnosis of MA in the elderly.

Review
Trochlear Migraine has been recently described as the concurrence of strictly unilateral migraine and ipsilateral trochleodynia with relief of migraine after successful treatment of trochleodynia. This disorder has been interpreted as "cluster-tic syndrome" or "seizure-triggered migraine". Trochlear Migraine is unrecognized and rarely described in childhood. The aim of this study is to review the few cases of Trochlear Migraine reported in the literature in addition to the cases observed in our clinical experience. In particular, our cases showed recurrent attacks of severe and pulsating headache associated with nausea, vomiting, phonophobia, photophobia, and strict trochlear localization of pain. They often presented with alternating side attacks. Therefore, we suggest that the term "Trochlear Migraine" should be reserved for clinical migraine attacks strictly localized in the trochlear region, and we assume that the excessive increase in descriptions of new primary headache syndromes, according to the International Classification of Headache Disorders, can be probably be ascribed to the common physiopathological mechanisms characterizing these forms of migraine.

Review
Hyperacusis is a recognized perceptual consequence of acoustic overexposure that can lead to debilitating psychosocial effects. Despite the profound impact of hyperacusis on quality of life, clinicians and researchers lack objective biomarkers and standardized protocols for its assessment. Outcomes of conventional audiologic tests are highly variable in the hyperacusis population and do not adequately capture the multifaceted nature of the condition on an individual level. This presents challenges for the differential diagnosis of hyperacusis, its clinical surveillance, and evaluation of new treatment options. Multiple behavioral and objective assays are emerging as contenders for inclusion in hyperacusis assessment protocols but most still await rigorous validation. There remains a pressing need to develop tools to quantify common nonauditory symptoms, including annoyance, fear, and pain. This review describes the current literature on clinical and investigational tools that have been used to diagnose and monitor hyperacusis, as well as those that hold promise for inclusion in future trials.

Review
Hyperacusis refers to the experience of the sound environment being perceived as overwhelmingly loud or painful, and this can severely affect the patient's quality of life. In China little attention has been paid to hyperacusis, and there has been little research undertaken on the topic. Therefore, this article summarizes the recent research on hyperacusis regarding definition, epidemiology, etiology, mechanism, evaluation and treatment to give directions for future research.
