Clinical study of elderly patients with Meniere's and related diseases

Endolymphatic Hydrops on Magnetic Resonance Imaging May Be an Independent Finding on Aging in Neurotologic Patients

OBJECTIVE

To clarify whether age impacts the development of endolymphatic hydrops (ELH) in neurotologic patients. Documentation of ELH in living patients on magnetic resonance imaging (MRI) allows analysis of patient age and formation of ELH, which is impossible by means of postmortem temporal bone pathology.

STUDY DESIGN

Retrospective case review.

SETTING

Tertiary referral center.

PATIENTS

Fifty patients (100 ears) with top 3 diagnoses of definite Menière's disease, delayed ELH, or probable Menière's disease.

INTERVENTIONS

Endolymph MRI after intravenous gadolinium injection and pure-tone audiometry.

MAIN OUTCOME MEASURES

Cochlear and vestibular ELH confirmed by MRI.

RESULTS

The prevalences of ears showing both cochlear and vestibular ELH were similar among age groups <30 years (30%), 30-59 years (25.9%), and ≥60 years (34.4%; p > 0.05; χ2 test). Using logistic regression modeling, mean hearing level at the six frequencies was positively associated with a higher risk of cochlear ELH (odds ratio, 1.3; 95% confidence interval, 1.1-1.5 per 10-dB increment). In the same regression model, age did not impact the outcome of cochlear ELH (odds ratio, 1.0; 95%confidence interval, 0.7-1.4 per 10-year increment). Age did not differ among ears with no ELH (mean ± standard deviation age, 48.6 ± 14.4 yr), ears with only cochlear ELH (59.3 ± 10.7 yr), ears with only vestibular ELH (50.4 ± 16.9 yr), or ears with both cochlear and vestibular ELH (51.5 ± 18.4 yr; p > 0.05, analysis of variance).

CONCLUSION

Chronological age was not associated with the formation of ELH. Aging per se may not be associated with the development of ELH in neurotologic patients.

Evolution of geriatric Meniere's disease during the past two decades

BACKGROUND

This study compared the incidence of Meniere's disease (MD) in the elderly aged >65 years between the first (2001-2010) and second (2011-2020) decades to investigate the evolution of geriatric MD.

METHODS

Totally, 1605 and 2550 patients with definite MD were experienced at the neurotological clinic during the first and the second decades, respectively. All patients were divided into three groups by 30-year age band, namely elderly (aged 65-94 years), adult (aged 35-64 years) and young (aged 5-34 years) groups, and underwent an inner ear test battery. Factors relating to the incidence of MD during the past two decades were analyzed.

RESULTS

The elderly MD group comprised 198 (12.4%) of 1605 MD cases during the first decade, and 463 (18.2%) of 2550 MD cases during the second decade, showing a significantly increased incidence of elderly MD. Correlation between annual life expectancy (x) in Taiwan and annual prevalence (y) of the elderly MD in relation to total MD cases revealed y = 0.023x - 1.660 via linear regression analysis. In contrast, the adult MD group significantly differed in terms of age and gender ratio, but not incidence, between the two decades. Conversely, the young MD group exhibited significantly decreased incidence from the first decade (22.3%) to the second decade (13.8%).

CONCLUSION

Evolution of geriatric MD during the past two decades reveals an increased incidence of the elderly MD patients, likely due to increased life expectancy coupled with altered life style.

Does Ménière's Disease in the Elderly Present Some Peculiar Features?

Object. Aim of our study was to establish some peculiar features of Ménière's Disease (MD) in a group of elderly MD patients, in which the first vertigo spell happened when over 65 years old. Material and Methods. We analyzed a group of 73 younger than 65-years-old and a group of 30 elderly MD patients. All patients underwent a neurotological evaluation, an anamnestic evaluation including a lifetime history of migraine, and blood withdrawal for autoantibody screening. Results. Some differences were found between elderly and younger MD patients. Elderly MD patients presented a higher prevalence of Tumarkin attacks and a lower prevalence of lifetime history of migraine; moreover, they presented a faster develop of hearing loss and vertigo spells than a subgroup of 32 younger patients matched for the duration of illness. Conclusions. Some clinical features of MD in elderly have been pointed out. Particularly, the lower rate of migrainous history and positivity for autoantibodies often associated with MD, in our opinion, support the hypothesis of a vascular disorder acting as a predisposing factor for MD in elderly.

Changes in the characteristics of definite Meniere's disease over time in Japan: a long-term survey by the Peripheral Vestibular Disorder Research Committee of Japan, formerly the Meniere's Disease Research Committee of Japan

CONCLUSION

The incidence of new cases of Meniere's disease (MD) in elderly patients aged 60 years or more was found to have increased over time after correction for age distribution in the overall population. Job- and care-related fatigue may be involved in the recent increase in elderly-onset cases because physical and mental fatigue can induce onset of the disease.

OBJECTIVES

Changes over time in the epidemiologic characteristics of MD in Japan were analyzed.

MATERIALS AND METHODS

Between 1975 and 2006, four nationwide, multi-center surveys of MD were conducted by the Meniere's Disease Research Committee of Japan (1975-1976) and the Peripheral Vestibular Disorders Research Committee of Japan (1982-1984, 1990, and 2001-2006). Information was collected by the committee members on a total of 1368 de novo cases of definite MD, 520 reported in the first survey, 290 in the second survey, 148 in the third survey, and 410 in the fourth survey.

RESULTS

Clear changes were seen over time in the population-adjusted sex distribution of the disease and population-adjusted age at onset. The number of definite MD cases in females increased over time relative to the number of cases in males. The proportion of cases in which onset occurred at 60 years of age or more increased over time when the number of cases in each age group was adjusted for changes in age distribution of the population over time. From the time of the third survey, there was a slight increase in the proportion of cases with bilateral involvement.
