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 balance disorders are not uncommon in children. The prevalence of vestibular vertigo in 10-year-Dolds is estimated to be 5.7%. The most common cause is vestibular migraine which accounts for almost 40% of the diagnoses. In adolescents, the incidence of somatoform vertigo syndromes increases. Vestibular function can be reliably evaluated at the bedside by the head-impulse test for vestibulo-ocular reflex function, ocular motor testing of the central vestibular system, and balance tests for vestibulo-spinal function. Vestibular migraine is treated by behavioural and drug therapies. Somatoform vertigo improves if information about the disorder and behavioual advice are provided. Sometimes psychotherapy is useful; drug therapy is recommended in severe cases. Other common vestibular disorders in children include benign positioning nystagmus and labyrinthitis. In summary, the underlying causes of vertigo and dizziness in children can be diagnosed on the basis of patient history and clinical bedside testing. Reponses to caloric irrigation of the ears, rotational chair testing, posturography, and video-oculography can be used to ascertain the diagnosis. Brain imaging is indicated in patients presenting with subacute central vestibular signs. The majority of syndromes have a favourable prognosis and can be successfully treated.

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.

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.

ObjectivesTo assess the period prevalence and severity of dizziness and vertigo in adolescents.MethodsIn 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.Results72.0% (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.ConclusionDizziness 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.

BPPV Benign paroxysmal positional vertigoVestibular 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.Vestibular paroxysmia is a disabling but, in most cases, medically treatable disorder. Individuals present with brief and frequent vertiginous attacks. 1 It is assumed that they are caused by neurovascular cross-compression at the root entry zone of the eighth cranial nerve.2 Positive diagnostic criteria for vestibular paroxysmia include the occurrence of frequent episodes that last seconds to minutes, which occur at rest and with certain head positions or position changes, and which respond to treatment with low-dose sodium channel-blocking antiepileptics such as carbamazepine (Table I). 1,3 The occurrence of vestibular paroxysmia in children has not yet been reported. Consequently, most paediatric neurologists are unfamiliar with this relevant and treatable condition. We report in detail on three children who presented to our tertiary referral outpatient child dizziness clinic and were subsequently diagnosed as having vestibular paroxysmia. Further, we summarize our experience in children with this condition seen at the German Center for Vertigo and Balance Disorders. CASE REPORTOut of the 400 children and adolescents (under 20y old) seen at our centre over a 10-year period, 16 (nine males, seven females) fulfilled the adult diagnostic criteria 1,3 for definitive or probable vestibular paroxysmia. The first symptoms occurred at mean age 13 years 11 months (SD 4y 0mo, range 5-19y). On average, the diagnosis was established 16 to 17 months after the initial onset of the symptoms. Three children from this cohort are described in this case report. They were chosen for their characteristic presentation and course. The patients and their parents consented to publication. Patient 1A 12-year-old female presented with a 6-month history of to-and-fro attacks of vertigo with blurred vision lasting 30 seconds and occurring 5 to 10 times daily. The bouts were provoked by headshaking, but they also occurred spontaneously while at rest. She did not experience headaches or any other neurological or audiological symptoms during the episodes. The child and her parents were worried that the symptoms might have a serious cause, even a brain tumour. Before presentation at our centre, they had consulted various medical specialists, including several paediatricians, a neurologist, an ear, nose, and throat specialist, an ophth...

In adolescents the association between self-reported neck and shoulder pain and migraine is most pronounced in migraine with a high attack frequency.
