Summary
Individuals with Ménière's disease (MD) experience cognitive-motor interference, particularly in demanding visuospatial and executive tasks. This study shows selective cognitive slowing under dual-task conditions, not affecting postural stability.
Area of Science:
- Neuroscience
- Cognitive Science
- Audiology
Background:
- Ménière's disease (MD) is known to affect cognitive functions.
- The precise nature of cognitive-motor interference in MD remains unclear.
- Understanding dual-task performance is crucial for evaluating MD's impact.
Purpose of the Study:
- To investigate dual-task performance in patients with MD compared to healthy controls.
- To examine cognitive-motor interference under combined cognitive and postural loads.
- To identify specific cognitive domains affected by dual-tasking in MD.
Main Methods:
- Employed a dual-task paradigm combining computerized dynamic posturography (CDP) with a cognitive test battery.
- Assessed visuospatial, executive, and working memory functions across varying postural difficulties (Sensory Organization Test - SOT).
- Analyzed performance data using mixed-effects models in 29 MD patients and 29 controls.
Main Results:
- Significant dual-task interference observed in MD patients for reaction times in Mental Rotation and Shifting Attention tasks.
- Performance slowing in these tasks increased disproportionately with postural difficulty in the MD group.
- No significant dual-task effects on postural stability were found in either group; MD patients showed baseline visuospatial working memory deficits.
Conclusions:
- Individuals with MD exhibit selective cognitive-motor interference, particularly in challenging visuospatial and executive tasks.
- A 'posture first' strategy may be employed, prioritizing postural control over cognitive processing.
- Dual-task paradigms offer a sensitive method for assessing cognitive burden in MD, informing clinical evaluation and management.

01:17Pathophysiology of Heart Failure
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
01:26Imbalances in Cardiac Output
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

01:21Fatigue
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...
01:20Mitral Regurgitation I: Introduction
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
01:29Heart Failure II: Pathophysiology
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
01:30Heart Failure VII: Nursing Interventions
The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
