Effectiveness of Telerehabilitation in Dizziness: A Systematic Review with Meta-Analysis

Dizziness can be a debilitating condition with various causes, with at least one episode reported in 17% to 30% of the international adult population. Given the effectiveness of rehabilitation in treating dizziness and the recent advancements in telerehabilitation, this systematic review aims to investigate the effectiveness of telerehabilitation in the treatment of this disorder. The search, conducted across Medline, Cochrane Central Register of Controlled Trials, and PEDro databases, included randomized controlled trials assessing the efficacy of telerehabilitation interventions, delivered synchronously, asynchronously, or via tele-support/monitoring. Primary outcomes focused on dizziness frequency/severity and disability, with secondary outcomes assessing anxiety and depression measures. Seven articles met the eligibility criteria, whereas five articles contributed to the meta-analysis. Significant findings were observed regarding the frequency and severity of dizziness (mean difference of 3.01, p < 0.001), disability (mean difference of -4.25, p < 0.001), and anxiety (standardized mean difference of -0.16, p = 0.02), favoring telerehabilitation. Telerehabilitation shows promise as a treatment for dizziness, aligning with the positive outcomes seen in traditional rehabilitation studies. However, the effectiveness of different telerehabilitation approaches requires further investigation, given the moderate methodological quality and the varied nature of existing methods and programs.

[Demographic and epidemiological risk factors in patients with acute vestibular neuritis]

OBJECTIVE

Vestibular neuritis (VN) is one of the most common peripheral vestibular balance disorder. Demographic and other risk factors associated with VN are insufficiently published. Therefore, the aim of this study is to identify associated risk factors in patients with acute VN.

METHODS

This study evaluated all hospitalized VN cases between 2017-2019. Inclusion criteria was an otoneurologically confirmed diagnosis of acute VN. Patient data was compared with data of the German normal population (Robert Koch Institute, "Gesundheit in Deutschland aktuell").

RESULTS

168 patients (Ø 59.8 years) were included. Compared with the normal German population, the study population was significantly more likely to have preexisting cardiovascular diseases, and the male patients were significantly more likely to have arterial hypertension. No significant differences were measurable between the study population and the normal population for other secondary diseases. Leukocytosis was present in 23% on admission, and 9% of patients reported a history of VZV or HSV-1 disease.

DISCUSSION

Etiology and pathogenesis of VN are poorly understood. Inflammatory and vascular causes are discussed. In this study, patients had increased prevalence of cardiovascular disease compared with the normal population, but the study population had a higher average age. Currently, it is unclear what significance nonspecific elevated leukocyte values could have as a possible sign of VN triggered by an infection. Since the number of inpatient cases with VN is rising, prospective studies should be performed to get a better understanding of the pathogenesis of the disease.

Potential Factors Associated with Healthcare Utilization for Balance Problems in Community-Dwelling Adults within the United States: A Narrative Review

Falls are the leading cause of mortality and chronic disability in elderly adults. There are effective fall prevention interventions available. But only a fraction of the individuals with balance/dizziness problems are seeking timely help from the healthcare system. Current literature confirms the underutilization of healthcare services for the management of balance problems in adults, especially older adults. This review article explores factors associated with healthcare utilization as guided by the Andersen Healthcare Utilization Model, a framework frequently used to explore the factors leading to the use of health services. Age, sex, race/ethnicity, BMI, and comorbidities have been identified as some of the potential predisposing factors; socioeconomic status, health insurance, and access to primary care are the enabling and disabling factors; and severity of balance problem, perceived illness, and its impact on daily activities are the factors affecting need for care associated with healthcare utilization for balance or dizziness problems. Knowledge about these barriers can help direct efforts towards improved screening of vulnerable individuals, better access to care, and education regarding effective fall prevention interventions for those who are at risk for underutilization. This can aid in timely identification and management of balance problems, thereby reducing the incidence of falls.

Hospital Admission Profile Related to Inner Ear Diseases in England and Wales

BACKGROUND

Due to an expansion in the usage of medications (such as anticancer therapies), increased exposure to noise, and an increase in life expectancy, the prevalence of inner ear disease-related hearing loss is rising. Diseases of the inner ear are frequently accompanied by other conditions, such as chronic heart failure, systemic inflammation, arterial hypertension, and cerebrovascular disease. The aim of this study was to investigate the profile of hospital admissions linked to inner ear diseases in England and Wales.

METHOD

This was an ecological descriptive study using public medical databases in England and Wales. Diagnostic codes for diseases of the inner ear (H80-H83) were used to identify all hospital admissions. Between 1999 and 2020, the chi-squared test was used to assess the difference between the admission rates.

RESULTS

From 5704 in 1999 to 19,097 in 2020, the total annual number of hospital admissions increased by 234.8%, which corresponds to a 192.3% increase in the admission rate [from 10.94 (95% CI 10.66-11.22) in 1999 to 31.98 (95% CI 31.52-32.43) in 2020 per 100,000 people, p < 0.01]. "Disorders of vestibular function" and "other inner ear diseases" were the most frequent causes of hospital admissions due to inner ear diseases, accounting for 47.6% and 43.6%, respectively. The age range of 15 to 59 years accounted for 42.3% of all diseases of the inner ear hospital admissions. Around 59.6% of all admissions were made by females. The female admission rate increased by 210.1% (from 12.43 (95% CI 12.01-12.85) in 1999 to 38.54 (95% CI 37.84-39.24) in 2020 per 100,000 people). The male admission rate for diseases of the inner ear increased by 169.6% [from 9.37 (95% CI 9.00-9.75) in 1999 to 25.26 (95% CI 24.69-25.84) per 100,000 people] in 2020.

CONCLUSION

Inner ear disease admissions increased markedly in England and Wales during the past two decades. Females and the middle-aged population were at higher risk of being admitted for inner ear diseases. Further cohort studies are warranted to identify other risk factors and develop effective prevention strategies.

[Effect of body mass index on efficacy of the repositioning procedure for horizontal canal benign paroxysmal positional vertigo]

Objective:To evaluate the effect of body mass index （BMI） on efficacy of the repositioning procedure for horizontal canal benign paroxysmal positional vertigo （HC-BPPV）. Methods:A total of 172 patients diagnosed with HC-BPPV in the First Affiliated Hospital of Xi'an Jiaotong University School of Medicine from Jan 2021 to Oct 2021 were enrolled. The patients were divided into low BMI group（BMI<24 kg/m² ） and high BMI group（BMI≥24 kg/m²）. The two groups underwent manual repositioning procedure and vertigo treatment system procedure by Barbecue method according to their orders of visits. After two circles of repositioning, the influencing factors of repositioning were analyzed according to efficiency. Results:The effective rate of manual repositioning in HC-BPPV patients was 33.64%, and the effective rate of vertigo treatment system was 63.08%,the effective rate of vertigo treatment system repositioning was higher than that of manual repositioning （P<0.05）. The effective rate of manual repositioning in the low BMI group （58.70%） was higher than that in the high BMI group （14.75%）, P<0.05. The effective rate of vertigo treatment system repositioning was higher in the low BMI group （75.00%） than that in the high BMI group （54.05%）, but there was no statistically significant difference between the two BMI groups （P>0.05）. Logistic regression analysis suggested that BMI was the influencing factor of HC-BPPV repositioning efficacy （P<0.05）. Conclusion:BMI can affect the efficacy of HC-BPPV manual repositioning. Vertigo treatment system for HC-BPPV reduction is better than manual reduction, and the efficacy is not affected by BMI.

Age-Associated Characteristics of Patients With Chronic Dizziness and Vertigo

OBJECTIVE

The incidence of dizziness and vertigo is increasing with age, and symptoms lead to significant limitations in daily living and to disability in older patients.

METHOD

Data of 1,752 patients with chronic dizziness/vertigo subjected to a tertiary care, specialized interdisciplinary vertigo center were analyzed. Age, gender, symptoms, medical diagnosis, and Dizziness Handicap Inventory (DHI) were collected based on a questionnaire and analysis of associated patient records. The patients were assigned to 3 age groups (< 41, 41-65, and > 65 years).

RESULTS

33.7% of the patients were older than 65 years. Frequency of symptoms and DHI score increased with age. Older patients reported less frequently about coexisting symptoms such as nausea, headache, tinnitus, ear pressure, and visual impairment. Multisensory deficit, central vertigo, bilateral vestibulopathy, and benign paroxysmal positional vertigo were diagnosed increasingly with age, while persistent postural-perceptual dizziness and vestibular migraine were diagnosed in the younger age groups.

CONCLUSION

In the diagnostic work-up of older patients age-specific characteristics of dizziness/vertigo have to be considered. The older patient generally is more impaired by the symptoms but possibly will not report typical diagnosis-defining symptoms.

How Healthcare Utilization Due to Dizziness and Vertigo Differs Between Older and Younger Adults

Background

Vertigo and dizziness are common in older adults. We describe self-reported healthcare utilization because of dizziness and vertigo in older adults attending a tertiary care specialized vertigo center.

Methods

Data from 765 patients (45% were ≥60 years old) with chronic dizziness and vertigo who attended a daycare multimodal treatment program were recorded. Data included sociodemographic parameters, dizziness-related characteristics, the Body Sensations Questionnaire (BSQ), the Agoraphobic Cognitions Questionnaire (ACQ), and the Hospital Anxiety and Depression Scale (HADS). Also, healthcare utilization, including (1) physician and clinical services, (2) hospitalizations in the year before consulting the vertigo center, (3) prescription of drugs and other professional services were included. Descriptive statistics, exploratory data analysis, and regression models were used.

Results

Intensity of dizziness was similar in both age groups, however, distress due to dizziness was more severe in younger persons. Dizziness symptoms lasted longer in older adults than in younger persons. Older adults had a somatic diagnosis (74.6 vs. 35.0%) more frequently and reported more falls (37.2 vs. 28.5%) than younger individuals. Anxiety about bodily sensations was higher in younger patients (mean BSQ1 = 9.33 ± 5.6) than in older patients (mean BSQ1 = 6.72 ± 5.4). Older persons had fewer depressive symptoms (mean HADS depression = 5.8 ± 3.6 vs. 6.5 ± 4.1) and less anxiety (mean HADS anxiety = 5.7 ± 3.7 vs. 7.8 ± 4.1) than younger individuals. Younger people were more frequently hospitalized (24.4%) than older adults (16.3%) in the year before consulting the vertigo center. Also, younger patients and patients with non-somatic etiologies had considerably more consultations with healthcare providers than older patients. Older adults received less medication (50.3%), less physiotherapy (41%), and less psychological therapy (11.6%) for vertigo than younger people (59.7, 52.2, 20.4%, respectively).

Conclusion

Age-associated differences in healthcare utilization were defined in selected patients attending a specialized vertigo center. Since dizziness is frequently a heterogeneous disorder requiring interdisciplinary care, its diagnostic and therapeutic work-up must be improved for older patients with dizziness.

Subjective versus objective tests of dizziness and vestibular function in epidemiologic screening research

BACKGROUND

Many epidemiologic studies of vestibular disorders are based on responses to questionnaires which have not been tested against objective tests of the vestibular system.

OBJECTIVE

The goal was to determine if the dizziness and balance questions used in the National Health Interview Survey (NHIS) are valid and predict performance on objective tests of the vestibular system (VNG).

METHODS

Data from 367 participants recruited from the community, aged 21.4 to 87.6 years, were collected in the Otolaryngology department at a tertiary care center. They were asked the eight NHIS questions twice, at least 30 minutes apart and were tested on VNG.

RESULTS

Question responses changed from Test 1 to Test 2 and differed between males and females. "Yes" responses did not predict abnormal VNG responses, for the total group and when the group was categorized into younger (<60 years) and older (>60 years) subjects. The sensitivity and specificity of all questions was low.

CONCLUSION

The NHIS questions provide some information about what people recall of their experiences, but they may not provide insight into the diagnostic prevalence of vestibular and balance disorders because the sensitivity and specificity are too low. Questionnaire-based epidemiologic studies should be interpreted with caution.

Efficacy and Pharmacological Appropriateness of Cinnarizine and Dimenhydrinate in the Treatment of Vertigo and Related Symptoms

Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Among these drugs, cinnarizine, usually given together with dimenhydrinate, appears to be the first-line pharmacotherapy for the management of vertigo and inner ear disorders. Based on these considerations, the present non-interventional study aimed to investigate the clinical efficacy and tolerability of a fixed combination of cinnarizine (20 mg) and dimenhydrinate (40 mg) in patients suffering from vertigo-related symptoms. To this end, we enrolled 120 adults-70 males, and 50 females-with an average age of 64 years. Before beginning pharmacological treatment, all patients were screened for the intensity of vertigo, dizziness, and concomitant symptoms through the Visual Scale of Dizziness Disorders and Dizziness Handicap Inventory scales. At the end of the anamnestic evaluation, patients received the fixed-dose combination of cinnarizine (20 mg) plus dimenhydrinate (40 mg) 3 times daily, for 60 days. The results of this study provide further insight regarding the efficacy of the fixed combination when used to reduce symptoms of vestibular vertigo of central and/or peripheral origin, after both the 15- and 60-day therapies. Independent of the type of vertigo, the fixed combination was able to reduce dizziness- and vertigo-associated symptoms in more than 75% of all patients treated, starting from 15 days of therapy, and improving 60 days after starting the therapy. Interestingly, we also found differences between male and female patients in the framework of the pharmacological effects of therapy. This study provides further details concerning the therapeutic efficacy of the fixed combination of cinnarizine and dimenhydrinate, and also focuses attention on the possibility that these drugs could act in a gender-specific manner, paving the way for further research.

Vestibular Impairments on Objective Diagnostic Tests in HIV+ Women and Control Men and Women

OBJECTIVE

To describe the value of two vestibular test batteries across ages in healthy men and women for detecting vestibular disorders and to compare the occurrence of vestibular disorders in the healthy adult population and women with human immunodeficiency virus (HIV) disease.

STUDY DESIGN

Two groups were tested on the battery of objective diagnostic tests of the vestibular system.

SETTING

Two tertiary care centers.

SUBJECTS

Healthy controls (284 women and 105 men) and women (63) with HIV/AIDS (HIV+) who are being followed up in a longitudinal study of HIV. They were tested on objective diagnostic tests of the vestibular system.

RESULTS

In all age decades, healthy controls had evidence of vestibular impairment, significantly more in older adults. HIV+ subjects, all females, did not differ from healthy control females.

CONCLUSION

These data suggest that at all ages, people do have decreased vestibular function, even young, asymptomatic, and apparently healthy adults. HIV disease, itself, does not cause an increased prevalence of peripheral vestibular disorders when HIV is controlled on antiretroviral medication.

MCQ-Balance: a method to monitor patients with balance disorders and improve clinical interpretation of posturography

Background

An estimated 20% to 30% of the global population has suffered a vertiginous episode. Among them, 20% do not receive a clear diagnosis. Improved methods, indicators and metrics are necessary to assess the sensory systems related to balance, especially when patients are undergoing treatment for vertiginous episodes. Patients with balance disorders should be monitored for changes at the individual level to gather objective information. In this study, we evaluate the use of the MCQ-Balance (Measure, Classify and Qualify) assessment for examining a patient’s balance progression using tests to measure static balance control and dynamic postural balance with a stabilometric platform.

Materials and Methods

The MCQ-Balance assessment comprises three stages: (i) measuring the progression of each variable between two separate and consecutive days (called sessions) using the Magnitude-Based Decision analysis; (ii) classifying the progression of the patient’s balance with a score; and (iii) qualifying the progression of the patient’s balance from the resulting scores using a set of rules. This method was applied to 42 patients with balance disorders of peripheral or central origin characterised by vertigo as the cardinal symptom. Balance progression was measured using the MCQ-Balance assessment over the course of three months, and these results were compared with the assessment of a clinical expert.

Results

The MCQ-Balance assessment showed an accuracy of 83.4% and a Cohen’s Kappa coefficient of 0.752 compared to the assessment of a clinical expert.

Conclusion

The MCQ-Balance assessment facilitates the monitoring of patient balance and provides objective information that has the potential to improve medical decision making and the adjustment of individual treatment.

Cognitive behavior therapy for dizziness: A protocol for systematic review and meta-analysis

OBJECTIVES

To investigate the association between cognitive behavior therapy (CBT) and dizziness.

METHODS

The databases including PubMed, Embase, Cochrane Library and Web of science will be searched for randomized controlled trials. Weighted mean difference and 95% confidence interval will be utilized to calculate the effect of CBT on dizziness between the 2 groups.

CONCLUSIONS

This meta-analysis will provide a high-quality synthesis from existing evidence for the relationship between CBT and dizziness.

Applying the Minimal Detectable Change of a Static and Dynamic Balance Test Using a Portable Stabilometric Platform to Individually Assess Patients with Balance Disorders

Balance disorders have a high prevalence among elderly people in developed countries, and falls resulting from balance disorders involve high healthcare costs. Therefore, tools and indicators are necessary to assess the response to treatments. Therefore, the aim of this study is to detect relevant changes through minimal detectable change (MDC) values in patients with balance disorders, specifically with vertigo. A test-retest of a static and dynamic balance test was conducted on 34 healthy young volunteer subjects using a portable stabilometric platform. Afterwards, in order to show the MDC applicability, eight patients diagnosed with balance disorders characterized by vertigo of vestibular origin performed the balance test before and after a treatment, contrasting the results with the assessment by a specialist physician. The balance test consisted of four tasks from the Romberg test for static balance control, assessing dynamic postural balance through the limits of stability (LOS). The results obtained in the test-retest show the reproducibility of the system as being similar to or better than those found in the literature. Regarding the static balance variables with the lowest MDC value, we highlight the average velocity of the center of pressure (COP) in all tasks and the root mean square (RMS), the area, and the mediolateral displacement in soft surface, with eyes closed. In LOS, all COP limits and the average speed of the COP and RMS were highlighted. Of the eight patients assessed, an agreement between the specialist physician and the balance test results exists in six of them, and for two of the patients, the specialist physician reported no progression, whereas the balance test showed worsening. Patients showed changes that exceeded the MDC values, and these changes were correlated with the results reported by the specialist physician. We conclude that (at least for these eight patients) certain variables were sufficiently sensitive to detect changes linked to balance progression. This is intended to improve decision making and individualized patient monitoring.

Peripheral Vestibular Disorders: Nationwide Evidence From Taiwan

OBJECTIVES/HYPOTHESIS

This study aimed to evaluate the prevalence of peripheral vestibular disorders in an Asian population of predominantly Han Chinese ethnicity.

STUDY DESIGN

Cross-sectional study.

METHODS

Patients with a peripheral vertigo disorder were identified from the Taiwan Health Insurance Research Database, a database of all medical claims of a randomly selected, population-representative sample of 2 million enrollees of Taiwan's National Health Insurance system covering over 99% of Taiwan's citizens. In 2016, 59,986 patients received a diagnosis of peripheral vestibular disorders in Taiwan. We calculated the population-wide prevalence rates of peripheral vestibular disorders in 2016 by sex and age group (20 to 24, 25 to 29, 30 to 34, 35 to 39, 40 to 44, 45 to 49, 50 to 54, 55 to 59, 60 to 64, 65 to 69, and ≥ 70 years) stratified into five urbanization levels.

RESULTS

The prevalence rate of peripheral vestibular disorders was 2,833.4 per 100,000 population during the year. Prevalence of Meniere's disease was 70.4 per 100,000, benign paroxysmal positional vertigo, 446.4, vestibular neuritis 307.2, and other or unspecified peripheral vestibular dizziness, 2,009.5 per 100,000. Prevalence rates steadily increased with age for every type of peripheral vestibular disorder, and were higher among females compared to males. The female-to-male gender ratios were 1.84, 1.89, and 1.93 for Meniere's disease, vestibular neuritis, and other peripheral vestibular dizziness, respectively. Counties with the lowest urbanization level had the highest prevalence rates of all types of peripheral vestibular disorders except vestibular neuritis.

CONCLUSIONS

Results showed that peripheral vestibular disorders are common in Taiwan, increase with age, are predominantly female, and show higher prevalence in rural areas.

Association of Cervical Spondylosis With Peripheral Vertigo: A Case-Control Study

OBJECTIVES/HYPOTHESIS

This study aimed to assess the association of prior cervical spondylosis (CS) with peripheral vertigo.

STUDY DESIGN

Case-control study.

METHODS

Data were retrieved from the Taiwan Longitudinal Health Insurance Database. A total of 2,570 patients who were newly diagnosed with peripheral vertigo were identified. We compared them with a 3:1 ratio of propensity score-matched patients, 7,710 comparison patients from the same dataset. We performed multivariate logistic regressions to estimate the odds ratio for prior CS occurrence among peripheral vertigo patients versus controls.

RESULTS

Of 10,280 sample patients, 1,739 (16.92%) patients had CS prior to the index date. A significant difference in prior CS between peripheral vertigo patients and controls (19.49% vs. 16.06%, P < .001) was observed. Logistic regression analysis shows that the odds of prior CS was 1.285 for peripheral vertigo patients versus controls (95% confidence interval [CI]: 1.143-1.446) after adjusting for age, sex, urbanization level, monthly income, geographic region, hyperlipidemia, diabetes, coronary heart disease, hypertension, and asthma. Prior CS with myelopathy was not associated with peripheral vertigo. Stratified analysis by age showed that the odds of CS were highest among patients with peripheral vertigo in the 45- to 64-year-old age group (1.442, 95% CI: 1.215-1.712).

CONCLUSIONS

CS is associated with subsequent peripheral vertigo in the Taiwan population, with higher risk among those aged 45 to 64 years.

Prevalence of Persistent Tinnitus and Dizziness in an Elderly Population in Southern Taiwan

OBJECTIVES

Tinnitus and dizziness are common among the elderly. The conditions may increase depression, and patients may become susceptible to falls, thereby affecting the quality of life of the geriatric population. Investigating the prevalence of persistent tinnitus and chronic/recurrent dizziness in an elderly population and analyzing the association of certain comorbidities with tinnitus and dizziness in southern Taiwan were the main purposes of this study.

MATERIALS AND METHODS

This was a cross-sectional study performed in a metropolitan hospital. Hearing tests were conducted in a total of 597 volunteers aged ≥65 years involving 322 (53.9%) men and 275 (46.1%) women recruited in the study. The pure tone average (PTA) and hearing handicap (HH) score were calculated. Patients completed questionnaires regarding the history of hypertension and diabetes and symptoms of tinnitus and dizziness. The association of gender, age, PTA/HH, body mass index (BMI), hypertension, diabetes, and metabolic syndrome (MetS) with tinnitus and dizziness were analyzed.

RESULTS

The prevalence of persistent tinnitus and chronic/recurrent dizziness was 32.0% and 24.1%, respectively. Tinnitus or dizziness were not associated with age, BMI, hypertension, diabetes, and MetS but was associated with hearing impairment. Women and those with fasting glucose levels <100 mg/dL were more likely to experience dizziness.

CONCLUSION

Persistent tinnitus and dizziness were common in an elderly population in southern Taiwan. These findings may help develop strategies to promote the quality of life in the elderly population.

Vestibular and oculomotor abnormalities among HIV-infected and HIV-uninfected men and women: A pilot study

OBJECTIVE

To determine if middle-aged and aging men and women with HIV disease (HIV+) should be screened for vestibular and oculomotor dysfunction.

METHODS

Age- and sociodemographically matched HIV+ and HIV- men and women were tested on vestibular evoked myogenic potential (VEMP), bi-thermic caloric testing, Dix-Hallpike maneuvers and saccades.

RESULTS

HIV+ men had more caloric weakness than HIV- men. HIV+ subjects had more saccade abnormalities than HIV- subjects. A saccade abnormality was positively associated with being HIV+. Among the HIV+ sample, abnormalities were associated with increasing age, being male, ever taking monotherapy, and having an undetectable viral load. Only being male and having an undetectable viral load were statistically significant. Unilateral caloric weakness had a decreased prevalence with age per 10 years, and being HIV+ showed an increased prevalence. In HIV+ subjects only, these abnormalities decreased with age and being male but increased with undetectable viral load and ever taking antiretroviral monotherapy. No statistically significant differences were found.

CONCLUSION

Women are at greater risk of vestibular and oculomotor abnormalities than men. HIV+ adults are at greater risk than HIV- adults. Physicians who care for HIV+ men and women should monitor the symptoms of vestibular and oculomotor impairment.

The Prevalence and Persistence of Dizziness in Older European Home Care Recipients: A Prospective Cohort Study

OBJECTIVES

The prevalence of different geriatric syndromes in older home care (HC) recipients is yet to be determined. Dizziness is often regarded as a geriatric syndrome. The natural course of dizziness in older people is still unknown, because of a lack of longitudinal studies. The objective of this study was to investigate the prevalence and persistence of dizziness in HC recipients.

DESIGN

Prospective cohort study.

SETTING

Home care organizations in 6 European countries participating in the EU-funded Identifying best practices for care-dependent elderly by Benchmarking Costs and outcomes of community care (IBenC) project.

PARTICIPANTS

2616 community-dwelling long-term HC recipients aged 65 years or older.

METHODS

Data were collected at baseline and 6 and 12 months by using the interRAI Home Care instrument (interRAI-HC). Dizziness status was assessed by the number of days people experienced dizziness in the last 3 days (0-3) and later dichotomized for analyses (present or not in the last 3 days). Dizziness persistence was defined as the odds for dizzy people at baseline to also report dizziness at subsequent follow-up moments, compared with people who were not dizzy at baseline. The pattern of dizziness was descriptively analyzed in recipients who completed all measurements. Generalized estimating equations analysis was used to determine the persistence of dizziness symptoms.

RESULTS

The prevalence of dizziness of 2616 eligible HC recipients at baseline was 25.1%, ranging from 16.2% (Belgium) to 39.7% (Italy). The majority of dizzy recipients at baseline also experienced dizziness after 6 and 12 months (79.1%). Dizziness persistence was high at 6 months [odds ratio (OR) 57.8, 95% confidence interval (CI) 43.1-77.5] and at 12 months (OR 30.2, 95% CI 22.3-41.1).

CONCLUSIONS AND IMPLICATIONS

Dizziness in older HC recipients in Europe is common, and dizziness persistence is high. This warrants a more active approach in treating dizziness in older HC recipients.

Identifying Key Risk Factors for Dizziness Handicap in Middle-Aged and Older People

OBJECTIVES

More than 10% of people aged 50 years and older report dizziness. Despite available treatments, dizziness remains unresolved for many people due in part to suboptimal assessment. We aimed to identify factors associated with dizziness handicap in middle-aged and older people to identify targets for intervention to address this debilitating problem. A secondary aim was to determine whether factors associated with dizziness differed between middle-aged (<70 years) and older people (≥ 70 years).

DESIGN

Secondary analysis of baseline and prospective data from a randomized controlled trial.

SETTING AND PARTICIPANTS

In total, 305 individuals aged 50 to 92 years reporting significant dizziness in the past year were recruited from the community.

METHODS

Participants were classified as having either mild or no dizziness handicap (score <31) or moderate/severe dizziness handicap (score: 31‒100) based on the Dizziness Handicap Inventory. Participants completed health questionnaires and underwent assessments of psychological well-being, lying and standing blood pressure, vestibular function, strength, vision, proprioception, processing speed, balance, stepping, and gait. Participants reported dizziness episodes in monthly diaries for 6 months following baseline assessment.

RESULTS

Dizziness Handicap Inventory scores ranged from 0 to 86 with 95 participants (31%) reporting moderate/severe dizziness handicap. Many vestibular, cardiovascular, psychological, balance-related, and medical/medications measures were significantly associated with dizziness handicap severity and dizziness episode frequency. Binary logistic regression identified a positive Dix Hallpike/head-roll test for benign paroxysmal positional vertigo [odds ratio (OR) 2.09, 95% confidence interval (CI) (1.11‒3.97)], cardiovascular medication use [OR 1.90, 95% CI (1.09‒3.32)], high postural sway when standing on the floor with eyes closed (sway path ≥160 mm) [OR 2.97, 95% CI (1.73‒5.10)], and anxiety (Generalized Anxiety Disorder Scale 7-item Scale score ≥8) [OR 3.08, 95% CI (1.36‒6.94)], as significant and independent predictors of moderate/severe dizziness handicap. Participants aged 70 years and over were significantly more likely to report cardiovascular conditions than those aged less than 70 years old.

CONCLUSIONS AND IMPLICATIONS

Assessments of cardiovascular conditions and cardiovascular medication use, benign paroxysmal positional vertigo, anxiety, and postural sway identify middle-aged and older people with significant dizziness handicap. A multifactorial assessment including these factors may assist in tailoring evidence-based therapies to alleviate dizziness handicap in this group.

In Older Patients Treated for Dizziness and Vertigo in Multimodal Rehabilitation Somatic Deficits Prevail While Anxiety Plays a Minor Role Compared to Young and Middle Aged Patients

Objective: Many patients with dizziness and vertigo are of older age. It is still unclear which age-associated factors play a role in the treatment of dizziness and vertigo. Therefore, age-associated characteristics of patients subjected to an interdisciplinary day care approach for chronic vertigo and dizziness were analyzed.

Subjects and Methods: 650 patients with chronic dizziness/vertigo subjected to a multimodal vestibular rehabilitation day care program were analyzed. Information concerning age, gender, medical diagnosis, medical consultations, technical diagnostics performed and therapy achieved before attending the clinic were collected. Furthermore, data were gathered using the Vertigo Severity Scale (VSS), Hospital Anxiety and Depression Scale (HADS), Mobility Inventory (MI), as well as the intensity of and the distress due to vertigo/dizziness using visual analog scales. As a follow-up, the VSS, HADS, MI, and the visual analog scales were collected again 6 months after attending the therapy program. Three age groups were compared to each other (<41, 41–65, and >65 years of age).

Results: One-third of the patients were older than 65 years. This group had typical diagnoses with mainly organic deficits. In contrast to the dominance of mainly multifactorial, organic deficits the older patients reported less medical consultations, fewer technical diagnostics and even fewer treatments than the younger patients. The elderly scored significantly lower in total VSS, in VSS-V (vestibular-balance subscale), in VSS-A (autonomic-anxiety subscale) and in HADS-anxiety. Psychological diagnoses were clearly associated to the younger patients. 424 patients (65.2%) completed the follow-up questionnaire 6 months after attending the therapy week. The older patients revealed improvements of VSS-V and the Avoidance Alone scale of MI as well as decreased distress due to vertigo/dizziness.

Conclusion: In the older patients, who took part in our vestibular rehabilitation program, mainly somatic deficits prevail while anxiety plays a minor role compared to young and middle aged patients. Older patients profited from vestibular rehabilitation especially in mobility and vestibular-balance. Therefore, vestibular rehabilitation programs for the elderly with a focus on physio- and occupational therapeutic interventions and less cognitive behavioral therapy may be reasonable.

Household debt and depressive symptoms among older adults in three continental European countries

In this comparative study focusing on the population aged 50 and over in three European countries, we investigate the association between household debt and depressive symptoms, and possible country differences in this association, using data from Waves 1, 2, 4, 5 and 6 of the Surveys of Health, Ageing and Retirement in Europe (SHARE) for Belgium, France and Germany. Multi-level regression models with random intercepts for individuals were used to analyse the association between household debt status and number of depressive symptoms (EURO-D score). Country differences in the household debt–depression nexus were tested using country interaction models. After controlling for other measures of socio-economic position and physical health, low or substantial financial debt was associated with a higher number of depressive symptoms in all countries. Housing debt was strongly linked to depressive symptoms for women while the association was weaker for men. The only country difference was that for both sexes substantial financial debt (more than €5,000) was strongly associated with depressive symptoms in Belgium and Germany, but the association was weak or non-significant in France. Associations between financial debt and depression were also evident in analyses of within-individual changes in depressive symptoms for a longitudinal sub-group, and in analyses using a dichotomised, rather than a continuous, measure of depression. The findings indicate that measures of household indebtedness should be taken into consideration in investigations of social inequalities in depression and suggest a need for mental health services targeted at indebted older people.

Reducing the burden of dizziness in middle-aged and older people: A multifactorial, tailored, single-blind randomized controlled trial

BACKGROUND

Dizziness is common among older people and is associated with a cascade of debilitating symptoms, such as reduced quality of life, depression, and falls. The multifactorial aetiology of dizziness is a major barrier to establishing a clear diagnosis and offering effective therapeutic interventions. Only a few multidisciplinary interventions of dizziness have been conducted to date, all of a pilot nature and none tailoring the intervention to the specific causes of dizziness. Here, we aimed to test the hypothesis that a multidisciplinary dizziness assessment followed by a tailored multifaceted intervention would reduce dizziness handicap and self-reported dizziness as well as enhance balance and gait in people aged 50 years and over with dizziness symptoms.

METHODS AND FINDINGS

We conducted a 6-month, single-blind, parallel-group randomized controlled trial in community-living people aged 50 years and over who reported dizziness in the past year. We excluded individuals currently receiving treatment for their dizziness, those with degenerative neurological conditions including cognitive impairment, those unable to walk 20 meters, and those identified at baseline assessment with conditions that required urgent treatment. Our team of geriatrician, vestibular neuroscientist, psychologist, exercise physiologist, study coordinator, and baseline assessor held case conferences fortnightly to discuss and recommend appropriate therapy (or therapies) for each participant, based on their multidisciplinary baseline assessments. A total of 305 men and women aged 50 to 92 years (mean [SD] age: 67.8 [8.3] years; 62% women) were randomly assigned to either usual care (control; n = 151) or to a tailored, multifaceted intervention (n = 154) comprising one or more of the following: a physiotherapist-led vestibular rehabilitation programme (35% [n = 54]), an 8-week internet-based cognitive-behavioural therapy (CBT) (19% [n = 29]), a 6-month Otago home-based exercise programme (24% [n = 37]), and/or medical management (40% [n = 62]). We were unable to identify a cause of dizziness in 71 participants (23% of total sample). Primary outcome measures comprised dizziness burden measured with the Dizziness Handicap Inventory (DHI) score, frequency of dizziness episodes recorded with monthly calendars over the 6-month follow-up, choice-stepping reaction time (CSRT), and gait variability. Data from 274 participants (90%; 137 per group) were included in the intention-to-treat analysis. At trial completion, the DHI scores in the intervention group (pre and post mean [SD]: 25.9 [19.2] and 20.4 [17.7], respectively) were significantly reduced compared with the control group (pre and post mean [SD]: 23.0 [15.8] and 21.8 [16.4]), when controlling for baseline scores (mean [95% CI] difference between groups [baseline adjusted]: -3.7 [-6.2 to -1.2]; p = 0.003). There were no significant between-group differences in dizziness episodes (relative risk [RR] [95% CI]: 0.87 [0.65 to 1.17]; p = 0.360), CSRT performance (mean [95% CI] difference between groups [baseline adjusted]: -15 [-40 to 10]; p = 0.246), and step-time variability during gait (mean [95% CI] difference between groups [baseline adjusted]: -0.001 [-0.002 to 0.001]; p = 0.497). No serious intervention-related adverse events occurred. Study limitations included the low initial dizziness severity of the participants and the only fair uptake of the falls clinic (medical management) and the CBT interventions.

CONCLUSIONS

A multifactorial tailored approach for treating dizziness was effective in reducing dizziness handicap in community-living people aged 50 years and older. No difference was seen on the other primary outcomes. Our findings therefore support the implementation of individualized, multifaceted evidence-based therapies to reduce self-perceived disability associated with dizziness in middle-aged and older people.

Multicenter data banking in management of dizzy patients: first results from the DizzyNet registry project

PURPOSE

Comprehensive phenotypical data across countries is needed to understand the determinants, prognosis and consequences of vestibular disease. The registry is a data repository for the members of the European DizzyNet. We report results from a pilot study using data from Turkey and Germany.

METHODS

The pilot study included a convenience sample of patients aged 18 or above referred to Ege University Medical School Hospital, Dokuz Eylül University Hospital, Izmir, Turkey, and the German Center for German Center for Vertigo and Balance Disorders, University on Munich, Germany, with symptoms of vertigo or dizziness. Health-related quality of life was assessed with the EQ5-D and the Dizziness Handicap Inventory (DHI). To obtain comparable groups we matched data from the two countries for age, sex and diagnosis by propensity score.

RESULTS

We included 80 adult patients, 40 from each country (60% female, mean age 54.1, SD 12.4). Matching was successful. Vestibular migraine (34%) was the most frequent diagnosis, followed by benign paroxysmal positional vertigo (29%) and Menière's disease (12%). Clinical signs and symptoms were comparable in both countries. Patients from Turkey were more likely to report headaches (65 vs. 32%) and to show gait unsteadiness (51 vs. 5%). Patients from Germany reported significantly higher quality of life and lower values of the DHI score.

CONCLUSIONS

Sharing data facilitates research, enhances translation from basic science into clinical applications, and increases transparency. The DizzyNet registry is a first step to data sharing in vestibular research across Europe.

Geriatric screening tools are of limited value to predict decline in functional status and quality of life: results of a cohort study

BACKGROUND

Geriatric screening tools are increasingly implemented in daily practice, especially in the oncology setting, but also in primary care in some countries such as the Netherlands. Nonetheless, validation of these tools regarding their ability to predict relevant outcomes is lacking. In this study we evaluate if geriatric screening tools predict decline in functional status and quality of life after one year, in a population of older cancer patients and an older primary care population without cancer with a life expectancy of at least six months.

METHODS

Older cancer patients and a general older primary care population without a history of cancer (≥ 70 years) were included in an on-going prospective cohort study. Data were collected at baseline and after one-year follow-up. Functional decline was based on the Katz Index and Lawton IADL-scale and was defined as deterioration on one or more domains. Decline in quality of life was measured using the global health related subscale of the EORTC QLQ-C30, and was defined as a decline ≥ 10 points. The selected geriatric screening tools were the abbreviated Comprehensive Geriatric Assessment, Groningen Frailty Indicator, Vulnerable Elders Survey-13, and G8. We calculated sensitivity, specificity, predictive values, and odds ratios to assess if normal versus abnormal scores predict functional decline and decline in quality of life.

RESULTS

One-year follow-up data were available for 134 older cancer patients and 220 persons without cancer. Abnormal scores of all screening tools were significantly associated with functional decline. However, this was only true for older persons without cancer, and only in univariate analyses. For functional decline, sensitivity ranged from 54% to 71% and specificity from 33% to 66%. For decline in quality of life, sensitivity ranged from 40% to 67% and specificity from 37% to 54%.

CONCLUSION

In older persons with a relatively good prognosis, geriatric screening tools are of limited use in identifying persons at risk for decline in functional status or quality of life after one year. Hence, a geriatric screening tool cannot be relied on in isolation, but they do provide very valuable information and may prompt physicians to also consider different aspects of functioning.
