Health-Related Quality of Life of Children/Adolescents with Vertigo: Retrospective Study from the German Center of Vertigo and Balance Disorders.

Purpose To assess the impact of vertigo on health-related quality of life (HrQoL) of children/adolescents and to assess if the impact on HrQoL varies by age group, gender, and type of vertigo diagnoses. Methods A retrospective analysis was performed on the clinical and HrQoL data of children and adolescents referred to the German Center of Vertigo and Balance Disorders (n = 32; male = 17; female = 15; age range: 8-18 years), using the KIDSCREEN-52 questionnaire. For each scale, means of the Z-scores with 95% confidence intervals of the study and norm sample were compared. By nonparametric Kruskal-Wallis statistics differences between diagnostic groups were assessed. To assess the gender- and age-specific impact of vertigo on quality of life, Wilcoxon signed-rank test was used. Results The means of the physical well-being, psychological well-being, autonomy scale, and the general HrQoL index of patients were considerably lower than the means of the norm sample. The physical well-being seemed to be most affected by vertigo. The reduction of HrQoL was not related to gender and vertigo types but seemed to be higher in children suffering from vertigo aged 12 to 18 years than children aged 8 to 11 years. Conclusion These are the first data to demonstrate impaired HrQoL in children with chronic vertigo.

Self-reported neck and shoulder pain in adolescents is associated with episodic and chronic migraine.

AIM: The aim of this study was to verify the association between self-reported neck/shoulder pain and migraine and to compare findings of chronic and episodic migraine in adolescents. METHODS: In this cross-sectional study, 601 secondary-school students filled in questionnaires about headache appearance, type and frequency, neck and shoulder pain and lifestyle factors. RESULTS: The adjusted strength of the association between reported neck and shoulder pain and migraine (assessed in multinomial regression models) increased with the frequency of migraine: less than once a week (OR = 1.40; 95% CI = (0.85-2.30)), weekly (OR = 2.14; 95% CI = (1.42-3.24)), and at least 15 days/month (OR = 7.27; 95% CI = (3.42-15.44)). CONCLUSION: In adolescents the association between self-reported neck and shoulder pain and migraine is most pronounced in migraine with a high attack frequency.

Vestibular Migraine in Children and Adolescents.

PURPOSE OF REVIEW: The goal of this review is to provide an actualized overview on vestibular migraine in childhood and adolescence, with focus on the epidemiology and clinical presentation as well as its treatment. RECENT FINDINGS: Vertigo spells in childhood can evolve into other periodic syndromes and/or migraine types and persist even into adulthood. Vestibular migraine (VM) and benign paroxysmal vertigo are the most common causes of vertigo in children and adolescents. The diagnostic criteria for VM are dizziness and vertigo, headache, phonophobia and photophobia, and visual aura. The prevention of attacks is the treatment for children and adolescents with VM, as is recommended for migraine with or without aura. Thus, non-pharmacological measures are the first-line option; when these measures fail or daily activities are notably affected, drugs are administrated. Psychological assessment and cognitive behavioral therapy are also important therapeutic measures in this patient group. There is still insufficient research on VM in children and adolescents; future studies on clinical presentation, evolvement, and specific treatment are necessary.

Vertigo and dizziness in children.

PURPOSE OF REVIEW: Vertigo and dizziness occur with considerable frequency in childhood and adolescence. Most causes are benign and treatable. This review aims to make physicians more alert to the frequent causes of dizziness in the young. RECENT FINDINGS: Epidemiological data confirm that migraine-related syndromes are the most common cause of vertigo in children. Vestibular migraine and benign paroxysmal vertigo have now been defined by the International Classification of Headache Disorders. About half of the adolescents with vertigo and dizziness show psychiatric comorbidity and somatization. Vestibular paroxysmia has been described as a new entity in children that can be treated with low doses of carbamazepine. To assess vestibular deficits, video head impulses (for the semicircular canals) and vestibular-evoked myogenic potentials (for the otoliths) are increasingly being used. SUMMARY: Pediatricians and neuro-otologists should be aware of the full spectrum of causes of vertigo and dizziness in children and adolescents. Vestibular function can reliably be tested nowadays. Although treatment for the common migraine-related syndromes can be done in analogy to the treatment of migraine in general, specific approaches are required for somatoform vertigo, the most frequent diagnosis in adolescent girls.

Vestibular paroxysmia in children: a treatable cause of short vertigo attacks.

Vestibular paroxysmia due to neurovascular compression is a syndrome consisting of frequent short episodes of vertigo in adults that can be easily treated. Here we describe the initial presentation and follow-up of three children (one female, 12y; two males, 8y and 9y) who experienced typical, brief, vertiginous attacks several times a day. Nystagmus was observed during the episodes. Cranial magnetic resonance imaging revealed arterial compression of the eighth cranial nerve. The attacks ceased after administration of low-dose carbamazepine (2-4mg/kg daily). Vestibular paroxysmia must be considered in the differential diagnosis of children with brief vertiginous episodes.

Migraine-related vertigo and somatoform vertigo frequently occur in children and are often associated.

Migraine-related syndromes are a common cause of episodic vertigo and dizziness in children. Somatoform vertigo (SV) is an important cause of chronic dizziness, especially in adolescents. Our aim was to elucidate the comorbidity of migraine and SV. Three diagnostic groups were defined: migraine-related vertigo (MRV), SV, and combined migraine-related and SV (MSV). A retrospective analysis was performed on patient data (demographics, diagnosis, neuro-orthoptic and neurologic status, and results of vestibular and balance testing) from 168 patients who were presented to the German Center for Vertigo and Balance Disorders (IFB) over a 2.5-year period. Mean age of patients was 12 ± 4 years (range: 1.4 to 18 years). The most frequent diagnosis was MRV (28%), followed by MSV (19%) and SV (14%). MSV occurred most frequently in adolescent girls (25%). MRV was the most common cause of dizziness in our cohort. MSV ranked second overall but ranked first in adolescent girls, followed by isolated SV. SV was most prevalent in adolescent girls. MRV, MSV, and SV account for about 60% of diagnoses established in our tertiary referral center. Competent care of childhood migraine should include skill in detecting both the clinical symptoms of vertigo and overlapping somatoform symptoms.

Self-reported muscle pain in adolescents with migraine and tension-type headache.

AIM: To identify possible associations between muscular pain and headache in adolescents in a large population-based sample. METHODS: Grammar school students were invited to fill in a questionnaire on headache and associated lifestyle factors. Headache was classified according to the German version of the International Classification of Headache Disorders (2nd edition). Muscular pain was assessed via denoting affected areas in schematic drawings of a body and via provoked muscular pain on controlled movements of head, neck and shoulder regions. RESULTS: Prevalence of any headache within the previous 6 months exceeded 80%. In all subjects muscular pain or pain on movement was most prominent in the neck and shoulder region, ranging from 9% to 27% in the non-headache population to up to 63% for individuals with migraine or mixed migraine and tension-type headache (TTH). Frequency of muscular pain increased significantly with growing chronicity of TTH. INTERPRETATION: A strong association between muscle pain in the neck/shoulder region and headache was observed, pointing to the importance of muscular pain for headache in adolescents. Also, in this age group muscular pain appears to be of particular importance in chronic TTH and - unexpectedly - in migraine, which is the most important new finding in our study.

Vertigo and dizziness in adolescents: Risk factors and their population attributable risk.

OBJECTIVES: To assess potential risk factors for vertigo and dizziness in adolescents and to evaluate their variability by different vertigo types. The role of possible risk factors for vertigo and dizziness in adolescents and their population relevance needs to be addressed in order to design preventive strategies. STUDY DESIGN: The study population consisted of 1482 school-children between the age of 12 and 19 years, who were instructed to fill out a questionnaire on different vertigo types and related potential risk factors. The questionnaire specifically asked for any vertigo, spinning vertigo, swaying vertigo, orthostatic dizziness, and unspecified dizziness. Further a wide range of potential risk factors were addressed including gender, stress, muscular pain in the neck and shoulder region, sleep duration, migraine, coffee and alcohol consumption, physical activity and smoking. RESULTS: Gender, stress, muscular pain in the neck and shoulder region, sleep duration and migraine were identified as independent risk factors following mutual adjustment: The relative risk was 1.17 [1.10-1.25] for female sex, 1.07 [1.02-1.13] for stress, 1.24 [1.17-1.32] for muscular pain, and 1.09 [1.03-1.14] for migraine. The population attributable risk explained by these risk factors was 26%, with muscular pain, stress, and migraine accounting for 11%, 4%, and 3% respectively. CONCLUSION: Several established risk factors in adults were also identified in adolescents. Risk factors amenable to prevention accounted for 17% of the total population risk. Therefore, interventions targeting these risk factors may be warranted.

Period Prevalence of Dizziness and Vertigo in Adolescents.

OBJECTIVES: To assess the period prevalence and severity of dizziness and vertigo in adolescents. METHODS: In 1661 students in 8th-10th grade in twelve grammar schools in Munich, Germany information on vertigo/dizziness was assessed by a questionnaire in the class room setting. Three month prevalence of dizziness/vertigo was estimated; symptoms were categorized as orthostatic dizziness, spinning vertigo, swaying vertigo or unspecified dizziness. Duration of symptoms and impact on daily life activities were assessed. RESULTS: 72.0% (95%-CI = [69.8-74.2]; N = 1196) of the students (mean age 14.5±1.1) reported to suffer from at least one episode of dizziness or vertigo in the last three months. Most adolescents ticked to have symptoms of orthostatic dizziness (52.0%, 95%-CI = [49.5-54.4], N = 863). The period prevalence for the other types of vertigo were spinning vertigo: 11.6%, 95%-CI = [10.1-13.3], N = 193; swaying vertigo: 12.2%, 95%-CI = [10.6-13.8], N = 202; and unspecified dizziness: 15.2%, 95%-CI = [13.5-17.1], N = 253. About 50% of students with spinning vertigo and swaying vertigo also report to have orthostatic dizziness. Most vertigo/dizziness types were confined to less than one minute on average. The proportion of students with any dizziness/vertigo accounting for failure attending school, leisure activities or obliging them to stay in bed were more pronounced for spinning or swaying vertigo. CONCLUSION: Dizziness and vertigo in grammar school students appear to be as common as in adults. In face of the high period prevalence and clinical relevance of dizziness/vertigo in adolescents there is a need for prevention strategies. Risk factors for dizziness/vertigo need to be assessed to allow for conception of an intervention programme.

Vestibular migraine in children and adolescents: clinical findings and laboratory tests.

INTRODUCTION: Vestibular migraine (VM) is the most common cause of episodic vertigo in children. We summarize the clinical findings and laboratory test results in a cohort of children and adolescents with VM. We discuss the limitations of current classification criteria for dizzy children. METHODS: A retrospective chart analysis was performed on 118 children with migraine related vertigo at a tertiary care center. Patients were grouped in the following categories: (1) definite vestibular migraine (dVM); (2) probable vestibular migraine (pVM); (3) suspected vestibular migraine (sVM); (4) benign paroxysmal vertigo (BPV); and (5) migraine with/without aura (oM) plus vertigo/dizziness according to the International Classification of Headache Disorders, 3rd edition (beta version). RESULTS: The mean age of all patients was 12 ± 3 years (range 3-18 years, 70 females). 36 patients (30%) fulfilled criteria for dVM, 33 (28%) for pVM, 34 (29%) for sVM, 7 (6%) for BPV, and 8 (7%) for oM. Somatoform vertigo (SV) co-occurred in 27% of patients. Episodic syndromes were reported in 8%; the family history of migraine was positive in 65%. Mild central ocular motor signs were found in 24% (most frequently horizontal saccadic pursuit). Laboratory tests showed that about 20% had pathological function of the horizontal vestibulo-ocular reflex, and almost 50% had abnormal postural sway patterns. CONCLUSION: Patients with definite, probable, and suspected VM do not differ in the frequency of ocular motor, vestibular, or postural abnormalities. VM is the best explanation for their symptoms. It is essential to establish diagnostic criteria in clinical studies. In clinical practice, however, the most reasonable diagnosis should be made in order to begin treatment. Such a procedure also minimizes the fear of the parents and children, reduces the need to interrupt leisure time and school activities, and prevents the development of SV.
