“…These alterations indicate a central compromise, or may be present in vestibular dysfunctions (5,17) . Therefore, the findings in this test, during vestibular examination, may assist in the early diagnosis of possible central alterations.…”

Purpose: To evaluate saccadic and pursuit ocular movements and optokinetic nystagmus in adults, analyzing the effect of age and visual alterations. Methods: We evaluated 40 subjects of both genders, aged 20-49 years, with no auditory or vestibular complaints and who presented a normal basic audiology evaluation, absence of spontaneous nystagmus with open eyes, semi-spontaneous nystagmus, and spontaneous nystagmus with eyes closed greater than 6º/s. All participants underwent the tests of spontaneous nystagmus, optokinetic nystagmus, fixed and random saccadic movements, and pendular tracking using computerized vectoelectronystagmography. The findings were analyzed according to age and visual changes (ametropias). The results underwent a descriptive and inferential analysis. Results: There was no difference in the tests of optokinetic nystagmus, fixed and random saccadic movement, and pendular tracking when analyzed with regard to age. As for the variable presence of visual alteration, directional preponderance of nystagmus, observed in the optokinetic nystagmus test, was higher in individuals with visual alterations. In the random saccadic movement, there was also a difference in relation to the maximum velocity, which was higher in individuals with no visual alterations. Conclusion: The oculomotor tests were not affected by the age factor in the studied age group, but the presence of visual alterations exerted influence on some of the parameters of the oculomotor tests.Keywords: Nystagmus, physiologic; Nystagmus, optokinetic; Saccades; Postural balance; Reflex, vestibulo-ocular RESUMO Objetivo: Avaliar os movimentos oculares de sácadas, perseguição e o nistagmo optocinético em adultos, analisando o efeito da idade e das alterações visuais. Métodos: Foram avaliados 40 sujeitos de ambos os gêneros, com faixa etária de 20 a 49 anos de idade, sem queixas auditivas ou vestibulares e que apresentaram avaliação audiológica básica dentro dos padrões da normalidade e ausência de nistagmo espontâneo de olhos abertos, nistagmo semi-espontâneo e nistagmo espontâneo de olhos fechados maior que 6º/s. Todos os participantes foram submetidos às provas de nistagmo espontâneo, nistagmo optocinético, movimentos sacádicos fixos, aleatórios e rastreio pendular, por meio da vectoeletronistagmografia computadorizada. Os achados foram analisados segundo as variáveis idade e presença de alteração visual, do tipo ametropias. Os resultados passaram por análise estatística descritiva e inferencial. Resultados: Não houve diferença nas provas de nistagmo optocinético, sacádico fixo, aleatório e rastreio pendular, quando analisadas com relação à idade. Quanto à variável alteração visual, a preponderância direcional do nistagmo, observada na prova do nistagmo optocinético, foi maior em indivíduos com alterações visuais. Nos movimentos sacádicos aleatórios, também se observou diferença em relação à velocidade máxima, sendo maior em indivíduos sem alterações visuais. Conclusão: As provas oculomotoras não sofreram influência do fator idad...

“…The three included articles in this study 16,18,19 presented similar methodologies, probably because they had the same authors and similar samples, composed of schoolchildren between 7 and 12 years of age, enrolled in public schools in the city of Piracicaba/ SP, in the years 2004/2005 18 and 2004/2006 16,19 . The sample was divided into two groups: schoolchildren with learning difficulties and schoolchildren without learning difficulties.…”

“…Since otoneurological factors can affect the data cited above, creating tools that aid in the early identification or construction of an ideal model of care becomes of extreme importance for the reduction of these rates. However, among the researched literature, there are few studies that effectively analyze the relationship of otoneurological symptoms with school learning [16][17][18][19] .…”

Purpose: this study aims to verify the level of scientific evidence on the relationship between dizziness and academic achievement in childhood. Methods: the study was performed using the following search terms: dizziness, vertigo, child, learning, spelling, learning skills, academic skills, reading, and their correspondents in Portuguese in the following databases: PubMed, Scielo, LILACS and PsycINFO. Observational studies that examined the relationship between dizziness and academic achievement in childhood, published between 2007 and 2017, were included. Articles that did not allow access to the full text, and studies based on samples with motor, hearing, and cognitive disorders were excluded. Results: we initially found 315 articles and three met the established inclusion and exclusion criteria. These were scored according to the Newcastle-Ottawa Modified Scale with scores between 2 and 3 and as IIb according to the American Speech-Language Hearing Association levels of evidence and quality indicators. Conclusion: the results of this integrative review showed a low level of scientific evidence on the relationship between dizziness and academic achievement in childhood. It is important to emphasize the importance of improving study design to better understand their relationship, to allow provision of the best preventive, assessment, and intervention methods.

“…Bilateral loss of vestibular function at or close to birth results in motor developmental delays (Rine et al, 2000; Whitney et al, 2009; Wiener-Vacher et al, 2012b). Although vestibular loss can be compensated with a return to normal postural and oculomotor functions, observations of such children throughout childhood reveal that many of those with complete vestibular loss exhibit learning disabilities and poorly adapted strategies for overcoming their sensory deficit (Franco and Panhoca, 2008). For example, the gaze and fixation problems associated with vestibular dysfunction can lead to reading problems requiring specific therapy (Braswell and Rine, 2006).…”

Vestibular signals play an essential role in oculomotor and static and dynamic posturomotor functions. Increasing attention is now focusing on their impact on spatial and non-spatial cognitive functions. Movements of the head in space evoke vestibular signals that make important contributions during the development of brain representations of body parts relative to one another as well as representations of body orientation and position within the environment. A central nervous system pathway relays signals from the vestibular nuclei to the hippocampal system where this input is indispensable for neuronal responses selective for the position and orientation of the head in space. One aspect of the hippocampal systems’ processing to create episodic and contextual memories is its role in spatial orientation and navigation behaviors that require processing of relations between background cues. These are also impaired in adult patients with vestibular deficits. However little is known about the impact of vestibular loss on cognitive development in children. This is investigated here with a particular emphasis upon the hypothetical mechanisms and potential impact of vestibular loss at critical ages on the development of respective spatial and non-spatial cognitive processes and their brain substrates.
