Dizziness and its association with walking speed and falls efficacy among older men and women in an urban population

Living with dizziness impacts health-related quality of life among older adults

Objective

This study aimed to compare older adults reporting dizziness to those not reporting dizziness regarding health-related quality of life (HRQL), distress due to dizziness, and balance confidence. A secondary aim was to investigate potential association between HRQL, number of falls, balance confidence, and distress due to dizziness.

Methods

Patients coming for bone density measurements answered questions regarding occurrence of dizziness. Patients reporting dizziness on a daily or weekly basis were considered eligible and invited for investigation at the Ear, Nose and Throat clinic at Södra Älvsborg Hospital, Sweden. Patients not reporting dizziness were considered eligible as controls. All patients answered the Dizziness Handicap Inventory (DHI), Activity Balance Confidence Scale (ABC-scale), and Euro-QoL-5D-3L questionnaires.

Results

A total of 55 dizzy patients came for physical investigation and answered the questionnaires and 47 non-dizzy participants only answered the questionnaires. The dizzy participants reported lower levels of balance confidence, lower HRQL, more prior falls, and higher levels of distress due to dizziness than the non-dizzy controls. Lower levels of balance confidence and higher level of distress due to dizziness were each associated with lower HRQL.

Conclusion

Dizziness, unsteadiness, and low balance confidence are associated with HRQL in a negative way. This is important to consider when measuring HRQL in a senior population, since a sensation of unsteadiness may indirectly contribute to low HRQL together with other symptoms.

Exploring Goals and Functional Changes in Reablement for People with Fractures and People with Dizziness and Balance Problems

Background

Although older people often have challenges with fractures and dizziness/balance problems, knowledge concerning the impact of reablement of people with these conditions is limited.

Aim

To explore functional changes in reablement for older home-dwelling people with fractures and dizziness/balance problems regarding 1) occupational performance and satisfaction with performance, 2) physical function and 3) health-related quality of life, and 4) which occupations they prioritize as rehabilitation goals.

Material and Methods

The sample is derived from a nationwide clinically controlled trial in Norway consisting of 149 participants with fractures and 113 with dizziness/balance problems who participated in a four to 10-week reablement program. Data were collected at baseline and at 10-week, 6-month, and 12-month follow-up and were analyzed with paired t-tests and analysis of covariance. Occupational priorities were categorized into sub-areas of occupation.

Results

Both groups had significant short-, mid-, and long-term improvements in occupational performance and satisfaction with performance. Except for balance from baseline to 12-month follow-up, the fracture group showed significant improvements in physical function and health-related quality of life at all follow-ups. The results varied more in the group with dizziness/balance problems in physical function and health-related quality of life. Functional mobility was the highest prioritized occupational sub-area in both groups.

Conclusion

The findings of this study provide extended knowledge about goals and functional changes in people with fractures and dizziness/balance problems following a reablement program.

Significance

Tailoring and individual adjustments according to diagnosis may be important in person-centered care in reablement.

AXS-05: an investigational treatment for Alzheimer's disease-associated agitation

INTRODUCTION

Agitation is common in patients with Alzheimer's disease (AD). Although nonpharmacologic de-escalation strategies are recommend as first-line treatment, medication is often needed to treat agitation. Currently, there are no FDA-approved medications for this indication. Psychotropics used to treat agitation include antipsychotics, which are notable for their efficacy but also their potential to cause serious side effects. AXS-05, a combination of dextromethorphan and bupropion, is currently being investigated for this indication.

AREAS COVERED

This review will discuss the pharmacology of AXS-05 and available clinical trial results from completed Phase I and Phase II/III studies assessing the potential for this compound to treat agitation in patients with AD. Ongoing research investigating AXS-05 for this indication will also be highlighted. Resources used for this review include PubMed, Embase, clinicaltrials.gov, and literature available on the manufacturer's website.

EXPERT OPINION

Early released clinical trial data indicate that AXS-05 may be a useful option to treat agitation in patients with AD, and that it appears to be generally well tolerated. AXS-05 may be especially helpful for patients with comorbid depression, when considering available data from separate phase III studies assessing the efficacy and safety of this compound in the treatment of depression.

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.

Dizziness and health-related quality of life among older adults in an urban population: a cross-sectional study

Background

Dizziness is a common complaint among older adults and may affect quality of life in a negative way. The aim of this study was to assess health-related quality of life (HRQL), sense of coherence (SOC), self-rated health (SRH) and comorbidity in relation to dizziness, among older persons from an urban population.

Methods

The study is part of the Gothenburg H70 Birth Cohort Studies (H70). A cross-sectional population-based sample including 662 79-years-olds (404 women, 258 men, 62% response rate) were surveyed with questions regarding dizziness, imbalance, comorbidities and general health. HRQL was assessed using the 36-item Short Form-36 Health Survey (SF-36) and SOC with the 13-items questionnaire Sense of Coherence (SOC-13).

Results

Half of the participants reported problems with dizziness (54%). Dizziness was negatively associated with HRQL, including after adjusting for comorbidities, especially in the physical domains of SF-36. Having dizziness was also associated with poorer SRH, tiredness and comorbidity among both men and women. SOC (mean total score), however, did not differ between dizzy and non-dizzy participants.

Conclusions

Dizziness was negatively associated with HRQL, also after adjusting for comorbidities. Identification and treatment of dizziness, when possible, are important because reduction of dizziness symptoms may potentially help to enhance overall well-being in this age group.

Effects of customized vestibular rehabilitation plus canalith repositioning maneuver on gait and balance in adults with Benign Paroxysmal Positional Vertigo: A Randomized Controlled Trial

BACKGROUND

Adults with unilateral posterior canal benign paroxysmal positional vertigo (BPPV) may continue to present with residual dizziness and balance impairments after the canalith repositioning maneuver (CRM). Customized Vestibular rehabilitation (VR) in addition to the standard CRM may improve postural control in adults with BPPV. However, the effectiveness of this intervention for improving dyanmic gait measures in adults with BPPV is unknown.

OBJECTIVE

We aimed to determine the effectiveness of customized VR in addition to the standard CRM on dynamic gait measures among adults with unilateral posterior canal BPPV.

METHODS

In this double blind, randomized controlled trial, 28 adults with BPPV were randomized to either control (n = 14, age: 54.36±8.55) or experimental (n = 14, age: 50.71±9.88) groups. The experimental and control groups received customized VR plus standard CRM for six weeks and standard CRM for two weeks respectively. Dynamic gait measures (duration of a complete gait cycle, stride velocity, turning duration and number of steps while turning) were recorded using a portable mobility sensor (iTUG) at baseline, week 4 and 6. A mixed model ANOVA was used to estimate the main effects of the interventions.

RESULTS

During walking, a group effect was demonstrated on gait duration, stride velocity, turning duration and number of steps while turning (p <  0.05).

CONCLUSIONS

Six weeks of customized VR performed in addition to the standard CRM was more effective than the standard CRM alone in improving balance and gait in adults with posterior canal BPPV. (252 words).

Benign paroxysmal positional vertigo and vestibular impairment among older adults with dizziness

OBJECTIVE

This article aimed to investigate older adults visiting a geriatric institution for a bone density measurement who reported dizziness on a daily or weekly basis (but who are not seeking care for dizziness), according to BPPV, vestibular function, walking abilities, and frequency of falls.

METHODS

Patients coming for a bone density measurement answered questions regarding occurrence of dizziness. Patients having dizziness on a daily or weekly basis were considered eligible for the study and invited for investigation at the Ear, Nose, and Throat clinic at Södra Älvsborg Hospital, Sweden. The patients answered questions about history of dizziness, medications, and comorbidities. They were also investigated for BPPV, vestibular deficits using the video head impulse test (vHIT), walking speed, Timed Up and Go test (TUG), and for perception of verticality and horizontality and Romberg test.

RESULTS

A total of 55 patients with dizziness were included. Fifteen (27%) were diagnosed with BPPV. Forty (73%) patients reported falling during the previous year, including 11 with BPPV. Dizziness when turning in bed was more common among patients with BPPV and increased the risk of BPPV 8-fold.

CONCLUSION

BPPV is common among older adults with dizziness, including among those not seeking medical care. It is important to identify older adults with BPPV and treat the condition since BPPV may contribute to falls. Asking about dizziness when turning in bed can help to distinguish patients with increased risk for BPPV and older adults with dizziness should be investigated for BPPV even when typical history is lacking. Level of evidence: 4.

"I can manage the challenge" - a qualitative study describing experiences of living with balance limitations after first-ever stroke

Purpose: To describe experiences of living with balance limitations after first-ever stroke.

Materials and methods: This study has a qualitative design, comprising interviews with 19 persons with first-ever stroke, ten women and nine men. Their mean age was 77 years and the mean time since stroke was 15 months. Stroke survivors who were able to walk outdoors with or without a walking aid and who were independent in toileting and dressing were invited to participate. Semi-structured individual interviews were performed. An inductive qualitative content analysis of the manifest and latent content was conducted.

Results: The results are presented in two themes illustrating the latent content of the data, “Feeling dizzy and unstable is a continuous challenge” and “Feeling confidence despite dizziness and unsteadiness”, and seven categories illustrating the manifest content: Limitations in daily life; Being emotionally affected; The need for physical support; Everything takes time; I can still manage; Feelings of acceptance; and Finding individual solutions.

Conclusions: All participants experienced the balance limitations as a continuous challenge in their everyday life, yet they also felt confidence. They had to some degree adapted their activities and were able to manage their daily life.

Innovations in Geroscience to enhance mobility in older adults

Aging is the primary risk factor for functional decline; thus, understanding and preventing disability among older adults has emerged as an important public health challenge of the 21st century. The science of gerontology - or geroscience - has the practical purpose of "adding life to the years." The overall goal of geroscience is to increase healthspan, which refers to extending the portion of the lifespan in which the individual experiences enjoyment, satisfaction, and wellness. An important facet of this goal is preserving mobility, defined as the ability to move independently. Despite this clear purpose, this has proven to be a challenging endeavor as mobility and function in later life are influenced by a complex interaction of factors across multiple domains. Moreover, findings over the past decade have highlighted the complexity of walking and how targeting multiple systems, including the brain and sensory organs, as well as the environment in which a person lives, can have a dramatic effect on an older person's mobility and function. For these reasons, behavioral interventions that incorporate complex walking tasks and other activities of daily living appear to be especially helpful for improving mobility function. Other pharmaceutical interventions, such as oxytocin, and complementary and alternative interventions, such as massage therapy, may enhance physical function both through direct effects on biological mechanisms related to mobility, as well as indirectly through modulation of cognitive and socioemotional processes. Thus, the purpose of the present review is to describe evolving interventional approaches to enhance mobility and maintain healthspan in the growing population of older adults in the United States and countries throughout the world. Such interventions are likely to be greatly assisted by technological advances and the widespread adoption of virtual communications during and after the COVID-19 era.

Benign paroxysmal positional vertigo, dizziness, and health-related quality of life among older adults in a population-based setting

Purpose

Dizziness may affect quality of life in a negative way and contribute to falls. The aim of this study was to investigate and compare 75 years old with dizziness caused by benign paroxysmal positional vertigo (BPPV) to those with general dizziness/impaired balance (non-BPPV related) and to those reporting no dizziness, regarding health-related quality of life (HRQL), falls, tiredness, and walking speed in a population-based setting.

Method

A cross-sectional population-based sample, including 671 75 years old (398 women, 273 men), was investigated for BPPV, dizziness symptoms, falls, and walking speed. HRQL was assessed using the 36-item Short Form-36 Health Survey (SF-36).

Result

A total of 67 persons (10%) had symptoms of BPPV with 11 (1.6%) having nystagmus when tested for BPPV. Having BPPV as well as general dizziness/impaired balance was associated with reduced HRQL, more tiredness, enhanced number of falls, and lower walking speed. Furthermore, the risk of having BPPV increased fourfold if symptoms of dizziness when turning in bed was reported.

Conclusion

Having problems with dizziness is common among senior citizens where BPPV can be an unrecognized cause of dizziness that may impact HRQL and overall well-being. As BPPV is common among older adults, and is potentially curable through reposition maneuvers, it is important to liberally test for, and treat the condition. Information about dizziness when turning in bed can help to pinpoint persons with enhanced risk for BPPV also on a population-based level.

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.

Ageing of the Diaphragm Muscle

The diaphragm muscle is the most important contractile district used for breathing. Like other muscles in the human body, it is subject to ageing and sarcopenia. Sarcopenia can be classified as primary (or age-related) when there are no local or systemic pathologies that cause a functional and morphological detriment of skeletal musculature. Secondary sarcopenia occurs when there is a cause or more pathological causes (illness, malnutrition, immobility) related or unrelated to ageing. In the elderly population, transdiaphragmatic pressure (Pdi) decreases by 20-41%, with a decline in the overall strength of 30% (the strength of the expiratory muscles also decreases). The article discusses the adaptation of the diaphragm muscle to ageing and some other ailments and co-morbidities, such as back pain, emotional alterations, motor incoordination, and cognitive disorders, which are related to breathing.
