“…10,11 Some epidemiological data was previously published in a Brazilian Journal. 6 Among the younger population, vestibular symptoms predominated, probably related to lifestyle and diet choices in this age group. It is well known that increased ingestion of soft drinks, sugar, high fat diet, and fast food as well as drug use and poor sleep patterns predispose to vestibular symptoms, and may trigger migraine.…”

“…Among the 18-25 year old respondents with dizziness, only 27% sought medical attention. As young adults had less frequent and recurrent symptoms than the elderly, 6 they may experience vertigo as a self-limited condition that does not demand medical investigation. Elderly people usually have more comorbidities and use more medication.…”

“…5 Until recently, there were no data on the prevalence of dizziness among the adult population of urban areas in Brazil. 6 According to the last census (2010) by the Brazilian Institute of Geography and Statistics (IBGE), the population of the city of São Paulo was estimated at 11,253,503 residents 7 within an area of 1,523Km 2 . São Paulo has the largest municipal GDP in Brazil, and is among the 10 wealthiest cities worldwide.…”

OBJECTIVE: This is a cross-sectional epidemiological survey designed to estimate the prevalence of dizziness among the adult population of the city of Sã o Paulo, Brazil, and to describe the clinical features and level of discomfort. METHOD: This population based study was conducted in the city of Sã o Paulo, Brazil, between April and October 2012. A total of 1,960 household interviews were completed. The following variables were assessed: gender, age, clinical characteristics of dizziness, and dizziness disability index. Chi-square test, Student's t-test, Tukey test and logistic regression were used for statistical analysis. RESULTS: The dizziness prevalence in Sã o Paulo was 42%. Peaks of dizziness were observed in two age groups: 49% among the 46 to 55 year-old, and 44% among the elderly subjects (. 65 years-old). Vestibular vertigo was detected in 8.3% of patients, with a strong female preponderance (p , 0.001). Symptoms caused disability in 27% of the affected respondents and were more frequent among women (p , 0.001). These sought medical care more frequently (p , 0.001). The dizziness disability index was significantly higher (p ¼ 0.0165) among subjects with a lower educational level. There was no correlation between dizziness discomfort and the type of job. CONCLUSION: The prevalence of dizziness in Sã o Paulo, Brazil, was established at 42%. Among the symptomatic subjects, 67% reported interruption of daily activities, but only 46% of them sought medical attention.

“…As with other sensory systems, vestibular function declines with age, and older individuals are disproportionately affected by vestibular loss. Some degree of physiologic vestibular impairment occurs in 50% of older adults age ≥ 60 years,1 and symptoms of vestibular loss such as imbalance with ambulation or unsteady vision (oscillopsia) are commonly reported by community‐dwelling older adults 6, 7, 8, 9, 10. The increased prevalence of vestibular loss in the older population has potentially substantial economic and societal consequences.…”

ObjectivesVestibular loss is a debilitating condition, and despite its high prevalence in older adults, the quality of life (QoL) burden of vestibular loss in older individuals has not been well‐studied. This report quantifies the impact on overall QoL and identifies domains of health most affected. We hypothesize vestibular loss will be associated with impairment in diverse domains of health‐related QoL.Study DesignProspective, case‐control study.MethodsA convenience sample of 27 patients age ≥60 years with vestibular physiologic loss was recruited from an academic neurotology clinic. The patients did not have any identifiable cause of their vestibular loss other than aging. The convenience sample was compared to an age‐matched cross‐sectional sample of the general US population (n = 1266). The main outcome was QoL measured by the Ontario Health Utilities Index Mark III (HUI3).ResultsCompared to the general population, patients with vestibular loss had significantly lower overall unadjusted HUI3 scores (−0.32, p < 0.001). Multivariate regression analysis showed vestibular loss was significantly associated with poorer performance in vision (−0.11 p < 0.0001), speech (−0.15, p < 0.0001), dexterity (−0.13, p < 0.0001), and emotion (−0.07, p = 0.0065). Adjusted aggregate HUI3 was also significantly lower for vestibular loss (−0.15, p = 0.0105). These QoL decrements resulted in an average loss of 1.30 Quality‐Adjusted Life Years (QALYs). When using a $50,000/QALY willingness‐to‐pay threshold, vestibular loss was associated with a $64,929 lifetime economic burden per affected older adult, resulting in a total lifetime societal burden of $227 billion for the US population ≥60 years of age.ConclusionsLoss of vestibular function with aging significantly decreases quality of life across multiple domains of well‐being. These QoL reductions are responsible for heavy societal economic burdens of vestibular loss, which reveal potential benefits of prompt diagnosis and treatment of this condition.Level of Evidence3

“…Balance can be defined as the ability to maintain a stable position of the body based on the location of mass center and gravity during static and dynamic positions, such as gait patterns 6,7 . It is a complex process, involving the reception and integration of sensory stimuli (vestibular, visual and proprioceptive), in harmony with the central nervous system (CNS) and the approaches according to the current symptom of each individual 18,20 . In such case, the inclusion of quantitative measure, especially regarding postural balance, considered one of the main factors of falls among the elderly, becomes necessary to better clinical decision making.…”

Resumo: OBJETIVO: avaliar a influência do tratamento com fármacos antivertiginosos sobre a qualidade de vida e o equilíbrio postural de adultos e idosos com queixas de tontura. MÉTODOS: estudo transversal, com amostra de 51 indivíduos portadores de queixas de tontura, divididos em dois grupos, de acordo com o uso (grupo medicado, n=25) ou não (grupo não medicado, n=26) de fármacos antivertiginosos. Foram coletadas informações sobre: caracterização dos sintomas (ficha elaborada pelos pesquisadores), autopercepção de qualidade de vida (Dizziness Handicap Inventory),intensidade de tontura (escala visual analógica de tontura) e equilíbrio postural (plataforma de força). RESULTADOS: verificou-se intensidade moderada de tontura (Média: 4,6 ± 2,8) e impacto negativo das vestibulopatias sobre a qualidade de vida (Média: 47,3 ± 22,4) na amostra total. Quando comparados os dois grupos, não houve diferença estatisticamente significante na intensidade da tontura (p=0,74) ou qualidade de vida (p=0,79), e também, nos parâmetros da estabilometria, em quatro tarefas (teste t independente, p>0,05). Contudo, após a inclusão do tempo de utilização de fármacos antivertiginosos como uma covariável do estudo, foi verificado pior desempenho nas diferentes tarefas da estabilometria no grupo medicado (ANCOVA, p<0,05). CONCLUSÃO: o uso de fármacos antivertiginosos não melhora a qualidade de vida de indivíduos com queixas de tontura e o equilíbrio postural esteve alterado no grupo medicado.
