Vertigo and dizziness in children: When to consider a neurological cause

Clinical Profile, Trends, and Management in Pediatric Patients with Audiovestibular Disorders: Can We Predict Emotional Disability in Pediatric Patients with Episodes of Vertigo and Dizziness?

BACKGROUND

Audiovestibular disorders in childhood occur with considerable frequency. However, the difficulty of obtaining medical history, the nonspecificity of symptoms, and the lack of cooperation during complementary tests often contribute significantly to diagnostic biases, attributing clinical presentations to psychosomatic disorders. The objectives of this work are, firstly, to characterize, from an auditory and vestibular perspective, the most frequent causes of vertigo in childhood and a possible relationship with emotional symptoms. On the other hand, to propose the usefulness of the MSSQ-Short questionnaire as a predictive variable in the evolution of children diagnosed with recurrent vertigo of childhood (RVC).

METHODS

An observational cross-sectional study was designed with retrospective data collection at three tertiary hospitals.

RESULTS

Among the 117 patients recruited between 2016 and 2024, 32 patients (27.35%) were diagnosed with an anxious-depressive syndrome prior to audiovestibular testing. The mean age was 11.19 ± 5.61 years and the most frequent final diagnoses were vestibular migraine (VM) with 41.03% and RVC with 23.93%. Patients with VM, compared with RVC, are approximately 1.12 times more likely to have psychosomatic pathology (CI 0.39 to 3.25). The most sensitive and frequently altered test was VEMPS (39.32%), with statistical significance in VM and otic capsule dehiscence, while regarding the MSSQ-Short questionnaire, the linear regression of 0.28 indicates an increase in clinical duration with high questionnaire scores.

CONCLUSIONS

Vestibular disorders causing dizziness and vertigo are challenging to diagnose, often due to lack of cooperation and/or symptom nonspecificity. A thorough medical history and complementary tests, including audiovestibular and imaging studies, are advisable, thus avoiding systematically attributing children's complaints to other psychosomatic disorders.

Instrumental Assessment and Pharmacological Treatment of Migraine-Related Vertigo in Pediatric Age

BACKGROUND

The most frequent form of vertigo in pediatric age is represented by vertigo linked to migraine, with a prevalence of 32.7%. This group of pathologies has received a redefinition of the diagnostic criteria to adapt them to the pediatric age with a new classification of the clinical pictures. We have several kinds of problems with these conditions that often have a significant impact on patients' and parents' quality of life: the diagnostic approach involves different tools for the different age groups contained in the pediatric range; the treatment of this type of vertigo is not consolidated due to the limited availability of trials carried out on pediatric patients. Focusing on this topic, the aim of this review was to provide an update on the more recent clinical advances in the diagnosis and treatment of Vestibular Migraine (VM) in children.

METHODS

We searched the PubMed, Embase, and Cochrane library databases for articles published in English from January 2015 to April 2023. The secondary search included articles from reference lists, identified by the primary search. Records were first screened by title/abstract, and then full-text articles were retrieved for eligibility evaluation. The searches combined a range of key terms ("Pediatric" AND "Childhood" AND "dizziness" OR "vertigo" AND "vestibular").

RESULTS

Migraine-related vertigo, in its most recent definitions and classifications, is the most frequent group of balance pathologies in pediatric age. The results from the various experiences present in the literature suggest a clinical approach to be integrated with the use of instrumental tests selected according to the age of the patient and the reliability of the results.

CONCLUSION

Knowing the timeline of the applicability of vestibular tests and the information that can be obtained from them is fundamental for diagnostic accuracy. Therapy is strongly conditioned by the limited availability of pediatric trials and by the wide range it includes, from very young children to adolescents.
