Dizziness and migraine: a causal relationship?

Both migraine and dizziness are very frequent complaints, but the comorbidity of the two disorders is higher than it might be expected to be on the basis of chance alone. This implies a possible causal relationship, but definite diagnostic criteria for migraine-related vertigo are still lacking. Very recent attempts in this direction have shown that migraine may be the third leading cause of vertigo and that migraine-related vertigo may be effectively treated. A review of the literature on this topic, which includes some preliminary data of our own, demonstrates the difficulty in pinpointing migraine-associated vertigo as a clearly-defined entity. However, there is a measure of agreement on a few points: the spells of vertigo occur in patients who habitually suffer from motion sickness, and who have a history of migraine, either without or with aura; the delay between migraine and vertigo onset may be several years; migraine-related vertigo may be described as rotatory and/or as a feeling of unsteadiness, and single spells can occur without any other accompanying symptoms, however, when spells do occur in association with headache, they usually precede it. The vertigo duration may be shorter or longer than that of the migraine aura since it ranges from a few seconds to a continuous condition of unsteadiness.     

Vestibular migraine: a critical review of treatment trials

Vestibular migraine (VM), also known as migraine-associated vertigo, is a common cause of dizziness in adults. We performed a comprehensive literature search regarding treatment for VM or migraine-associated vertigo during the period of 1990–2008 and used, individually or in combination, the search terms VM, migraine-associated vertigo, migraine-associated dizziness, migrainous vertigo, migraine and vertigo, migraine and disequilibrium, and headache and vertigo. We found nine publications that address treatment strategies for VM. One small randomized clinical trial found some benefit from the use of zolmitriptan for abortive treatment of VM. The other eight observational studies showed marginal improvement with migraine prophylactic medications such as nortriptyline, verapamil, or metoprolol. Until more specific treatment options become available, patients with VM need to be managed with similar prophylactic and abortive strategies as those used for migraine in adults.     

Migraine Associated Vertigo

The interrelations of migraine and vertigo are complex, eluding a simple localization either centrally or peripherally. Spontaneous episodic vertigo, benign paroxysmal positional vertigo, and Meniere''s disease all occur more frequently in patients with migraine than in those without. Family studies support a hereditary predisposition to migraine associated vertigo. In this review, we discuss definitions, epidemiology, associated syndromes, neurootological abnormalities, genetics and treatment for patients with migraine and vertigo.     

Migraine-related vertigo: Diagnosis and treatment

A comprehensive review of the neurotologic manifestations of migraine is presented, focusing on the most recent publications regarding the epidemiology, clinical presentation, pathophysiology, diagnosis, and management of migraine-related vertigo (MV). A strong association exists between vertigo and migraine, with MV being the most common cause of spontaneous (nonpositional) episodic vertigo. Symptoms can be quite variable among patients and within individual patients over time, creating a diagnostic challenge. MV generally presents with attacks of spontaneous or positional vertigo lasting seconds to days with associated migrainous symptoms. Operational diagnostic criteria have been proposed but are not included in the most recent International Headache Society classification of migraine. Better elucidation of the neurologic linkages between the central vestibular pathways and migraine-related pathways and the discovery of ion channel defects underlying some causes of familial migraine, ataxia, and vertigo have furthered the understanding of MV pathophysiology. Treatment of MV currently parallels that of migraine headache, as proper studies of optimal MV management are just beginning.

The interrelations of migraine, vertigo, and migrainous vertigo

OBJECTIVE: To assess the prevalence of migrainous vertigo in patients with migraine and in patients with vertigo according to explicit diagnostic criteria that are presented for discussion. METHODS: The authors prospectively evaluated 200 consecutive patients from a dizziness clinic and 200 patients from a migraine clinic for migrainous vertigo based on the following criteria: 1) recurrent vestibular symptoms (rotatory/positional vertigo, other illusory self or object motion, head motion intolerance); 2) migraine according to the criteria of the International Headache Society (IHS); 3) at least one of the following migrainous symptoms during at least two vertiginous attacks: migrainous headache, photophobia, phonophobia, visual or other auras; and 4) other causes ruled out by appropriate investigations. In addition, the authors compared the prevalence of migraine according to the IHS criteria in the dizziness clinic group with a sex- and age-matched control group of 200 orthopedic patients. RESULTS: The prevalence of migraine according to the IHS criteria was higher in the dizziness clinic group (38%) compared with the age- and sex-matched control group (24%, p < 0.01). The prevalence of migrainous vertigo was 7% in the dizziness clinic group, and 9% in the migraine clinic group. In 15 of 33 patients with migrainous vertigo, vertigo was regularly associated with migrainous headache. In 16 patients, vertigo occurred both with and without headache, and in two patients headache and vertigo never occurred together. The duration of attacks varied from minutes to days. CONCLUSION: These results substantiate the epidemiologic association between migraine and vertigo and indicate that migrainous vertigo affects a significant proportion of patients both in dizziness and headache clinics.     

Epidemiology of vertigo,migraine and vestibular migraine

Both migraine and vertigo are common in the general population with lifetime prevalences of about 16 % for migraine and 7 % for vertigo. Therefore, a concurrence of the two conditions can be expected in about 1.1 % of the general population by chance alone. However, recent epidemiological evidence suggests that the actual comorbidity is higher, namely 3.2 %. This can be explained by the fact that several dizziness and vertigo syndromes occur more frequently in migraineurs than in controls including benign paroxysmal positional vertigo, Meniere’s disease, motion sickness, cerebellar disorders and anxiety syndromes which may present with dizziness. In addition, there is increasing recognition of a syndrome called vestibular migraine (VM), which is vertigo directly caused by migraine. VM affects more than 1 % of the general population, about 10 % of patients in dizziness clinics and at least 9 % of patients in migraine clinics. Clinically, VM presents with attacks of spontaneous or positional vertigo lasting seconds to days. Migrainous accompaniments such as headache, phonophobia, photophobia or auras are common but not mandatory. Cochlear symptoms may be associated but are mostly mild and non-progressive. During acute attacks one may find central spontaneous or positional nystagmus and, less commonly, unilateral vestibular hypofunction. In the symptom-free interval, vestibular testing adds little to the diagnosis as findings are mostly minor and non-specific. In the absence of controlled studies, treatment of VM is adopted from the migraine sphere comprising avoidance of triggers, stress management as well as pharmacotherapy for acute attacks and prophylaxis.     

Vestibular migraine: objective diagnostic criteria

Classification of migraine or vertigo based only on clinical symptoms is rather difficult, especially in the postacute stage. The use of diagnostic instrumentation greatly aids clinicians in offereing objective measures of patient physiology. In migraine and vertigo, the “gold standard” objective measure has not been fully defined thereby hindering a criteria for vestibular migraine. This study proposes the use of two seperate modalities; infrared videonystagraphy for vertigo and electric pain thresholds for migraine to quantify patient complaints. While these instruments offer to document patient pathophsyiology, simple clinical procedures are presented to provoke the dizzyness of vertigo and the allodynia of migraine in patients being evaluted allowing clinicians larger diagnostic and therapeutic options Received: 28 November 2002 / Accepted: 30 January 2003 Correspondence to: J.

Migrainous vertigo: development of a pathogenetic model and structured diagnostic interview

PURPOSE OF REVIEW: Vestibular symptoms occur frequently in patients with migraine. This review refines recently proposed diagnostic criteria for migraine-related vestibular symptoms, and develops a pathophysiological model for the interface between migraine and the vestibular system. RECENT FINDINGS: The epidemiological link between migraine and vestibular symptoms and signs suggests shared pathogenetic mechanisms. Links between the vestibular nuclei, the trigeminal system, and thalamocortical processing centers provide the basis for the development of a pathophysiological model of migraine-related vertigo. During the last year, several studies have increased understanding of the relationship between migraine and vestibular symptoms. A study of motion sickness and allodynia in migraine patients supports the importance of central mechanisms of sensitization for migraine-related vestibular symptoms. A study has demonstrated effective treatment of vertigo with migraine therapy. The identification of migrainous vertigo, however, is hampered by a lack of standardized assessment criteria for both clinical and research practices. The application of published criteria for the diagnosis of migrainous vertigo allows the development of a standardized, structured assessment interview. SUMMARY: An understanding of the relationship between migraine and the vestibular system increases knowledge of the pathogenesis of both migraine and vertigo. In addition, studies have identified successful treatment, with standard migraine therapies, of vestibular symptoms in patients with both migraine and vertigo. The use of a standardized assessment tool to identify this unique population of patients will help future studies to test both the pathological model and effective treatment options.     

Recent advances in the genetics of recurrent vertigo and vestibulopathy

PURPOSE OF REVIEW: To focus on recent advances in the genetics of recurrent vertigo, with an overview on episodic ataxia, benign recurrent vertigo (mainly migraine-associated vertigo), bilateral vestibulopathy, and Ménière's disease. RECENT FINDINGS: Since the identification more than a decade ago of the genetic causes of episodic ataxia type 1 with myokymia caused by KCNA1 mutations and episodic ataxia type 2 with nystagmus caused by CACNA1A mutations, the list of episodic ataxia syndromes with distinct clinical features and genetic loci is slowly expanding, now up to episodic ataxia type 7. There is growing recognition for a correlation between benign recurrent vertigo and migraine, and acceptance for vertigo as a manifestation of migraine; efforts to identify susceptibility loci for migraine and migraine-associated vertigo are underway. A handful of families with vestibulopathy spanning several generations have been identified. Although no gene has yet been found, vestibulopathy with normal hearing variably associated with migraine is likely monogenic and heterogeneous, similar to nonsydromic deafness. There is also continuing effort to identify genetic causes of familial Ménière's disease. SUMMARY: Overlapping clinical features among different familial syndromes of recurrent vertigo and strong association with migraine suggest shared mechanisms. Collaborative efforts in patient identification and recruitment will facilitate progress in understanding disease mechanisms to improve diagnosis and treatment of recurrent vertigo.     

Neuro-otological features of benign paroxysmal vertigo and benign paroxysmal positioning vertigo in children: a follow-up study

BACKGROUND: Causes of benign episodic vertigo in paediatric age include benign paroxysmal vertigo of childhood (BPV) and benign paroxysmal positional vertigo (BPPV). OBJECTIVE: The aim is to review the clinical, audiological and vestibular findings in a cohort of children with BPV and in a group of children with BPPV and to highlight the differences useful to formulating a differential diagnosis. METHODS: Eighteen children, aged 4-9 years, consecutively examined for paroxysmal attacks of dizziness and/or vertigo attacks between January 2002 and December 2002 entered our study. The clinical characteristics of vertigo, presence of triggering factors, family history of migraine, presence of motion sickness, migraine and other accompanying symptoms were considered. Neurological, ophthalmologic, vestibular and auditory functions were assessed. RESULTS: Eight children suffered from BPPV and ten children from BPV. In the BPPV group, the vestibular examination was normal except for the Dix-Hallpike maneuver. Liberatory maneuvers were immediately effective in all patients and all remained symptom-free during the follow-up. In the BPV group, the vestibular examination was positive in 3 patients but none had positive Dix-Hallpike maneuver. All patients with BPV have a positive family history of migraine and seven had a history of motion sickness. In all, migraine was present one year before the vertigo symptoms, with a frequency of at least two migraine episodes a month. CONCLUSION: BPV differs from BPPV in terms of family history, clinical symptoms, otoneurological signs, therapy and clinical evolution. BPPV is characterized by specific otoneurological signs, and must be treated with liberatory maneuvers: neither medical therapy nor strict follow-up is needed.     

Migraine and isolated recurrent vertigo of unknown cause

Chronic recurrent attacks of vertigo, not associated with any auditory or neurological symptoms, are a common reason for referral to our neurotology clinic. Even after an extensive neurotological evaluation, some cases remain undiagnosed. We prospectively evaluated 72 consecutive patients who presented to the clinic with isolated recurrent vertigo of unknown cause. All patients underwent diagnostic evaluation to exclude identifiable causes of isolated recurrent vertigo. We compared the prevalence of migraine, according to the International Headache Society (IHS) criteria, in the isolated recurrent vertigo group, with a sex- and age-matched control group of orthopedic patients. The prevalence of migraine according to IHS criteria was higher in the isolated recurrent vertigo group (61.1%) than in the control group (10%; p < 0.01). Only 16.7% of patients had an abnormal vestibular function test. The most common abnormal finding was a unilateral vestibular weakness to caloric stimulation. Our results suggest that migraine should be considered in the differential diagnosis of isolated recurrent vertigo of unknown cause.

Episodic vertigo related to migraine (90 cases): vestibular migraine?

A retrospective study was conducted on 90 patients with episodic vertigo that could be related to migraine as the most probable pathomechanism. Since the majority of the patients did not fulfill the criteria of the International Headache Society (IHS) for basilar migraine, the diagnosis was substantiated by disease course, medical efficacy in treating (ergotamines) and preventing (metoprolol, flunarizine) attacks, ocular motor abnormalities in the symptom-free interval, and careful exclusion of the most relevant differential diagnoses, such as transient ischemic attacks, Menière’s disease, and vestibular paroxysmia. The following clinical features were elaborated. The initial manifestation could occur at any time throughout life, with a peak in the fourth decade in men and a “plateau” between the third and fifth decades in women. The duration of rotational (78%) and/or to-and-fro vertigo (38%) could last from a few seconds to several hours or, less frequently, even days; duration of a few minutes or of several hours was most frequent. Monosymptomatic audiovestibular attacks (78%) occurred as vertigo associated with auditory symptoms in only 16%. Vertigo was not associated with headache in 32% of the patients. In the symptom-free interval 66% of the patients showed mild central ocular motor signs such as vertical (48%) and/or horizontal (22%) saccadic pursuit, gaze-evoked nystagmus (27%), moderate positional nystagmus (11%), and spontaneous nystagmus (11%). Combinations with other forms of migraine were found in 52%. Thus, migraine is a relevant differential diagnosis for episodic vertigo. According to the criteria of the IHS, only 7.8% of these patients would be diagnosed as having basilar migraine. However, to ensure that at least those presenting with monosymptomatic episodic vertigo (78% in our study) receive effective treatment, we propose the use of the more appropriate term “vestibular migraine.” Received: 22 September 1998 Received in revised form: 3 March 1999 Accepted: 16 March 1999     

Migraine and isolated recurrent vertigo of unknown cause

Abstract

Chronic recurrent attacks of vertigo, not associated with any auditory or neurological symptoms, are a common reason for referral to our neurotology clinic. Even after an extensive neurotological evaluation, some cases remain undiagnosed. We prospectively evaluated 72 consecutive patients who presented to the clinic with isolated recurrent vertigo of unknown cause. All patients underwent diagnostic evaluation to exclude identifiable causes of isolated recurrent vertigo. We compared the prevalence of migraine, according to the International Headache Society (IHS) criteria, in the isolated recurrent vertigo group, with a sex- and age-matched control group of orthopedic patients. The prevalence of migraine according to IHS criteria was higher in the isolated recurrent vertigo group (61.1%) than in the control group (10%; p< 0.01). Only 16.7% of patients had an abnormal vestibular function test. The most common abnormal finding was a unilateral vestibular weakness to caloric stimulation. Our results suggest that migraine should be considered in the differential diagnosis of isolated recurrent vertigo of unknown cause.     

Migraine-related vertigo: towards a distinctive entity

Both migraine and vertigo are common complaints. Although they may coincide by chance, there is growing evidence for a clinical entity of recurrent vestibular symptoms related to migraine. This syndrome implies a possible causal relationship although the pathophysiology of migraine-related vertigo has not been fully elucidated. A migrainous aseptic inflammation is thought to create a central sensitivity that spreads from the trigeminal to the vestibular system. Diagnostic criteria for migraine-related vertigo are proposed. Treatment is based on anti-vertiginous drugs for acute interventions and prophylactic measures as are taken for migraine headaches. Multicenter, prospective controlled studies are highly warranted.

Problems in childhood migraine

There are differences between childhood and adult migraine which justify clinical research. First, inessential differences, such as prominence of systemic upset, indicate need for clinical drug trials. Second, some paroxysmal phenomena of childhood such as paroxysmal torticollis, vertigo, and hemiplegia may be migraine precursors, and need therapeutic trials. Third, some proposed equivalents of migraine in childhood need study and definition, followed by clinical trials.     

Episodic vertigo: central nervous system causes.

Episodic ataxia type 2 is a prototypical episodic vertigo and ataxia syndrome that is caused by mutations in the calcium channel gene CACNA1A. Recent discoveries regarding the molecular mechanisms that underlie this syndrome provide a model for understanding the more common familial episodic vertigo syndromes, particularly those associated with migraine. Vertigo due to cerebrovascular disease can be of peripheral or central origin, and can mimic more benign peripheral vestibular disorders. Small infarcts in the cerebellum and lateral medulla can present with vertigo without other localizing symptoms.
