Summary
Hearing loss is common in dementia, affecting over 80% of individuals. Early detection and management, including hearing aid use, may improve neuropsychiatric symptoms and quality of life.
Area of Science:
- Gerontology
- Neuroscience
- Audiology
Background:
- Hearing loss is a frequent comorbidity in dementia, impacting over 80% of individuals.
- Prevalence increases with age and cognitive impairment severity.
- Underdiagnosis is common, as proxy reports underestimate hearing loss.
Purpose of the Study:
- To review the epidemiology of hearing loss in dementia.
- To discuss clinical presentation, assessment, and management strategies.
- To highlight the impact of hearing loss on neuropsychiatric symptoms and potential benefits of hearing aid use.
Main Methods:
- Review of epidemiological data from US-based cohorts.
- Discussion of clinical assessment tools and management options.
- Exploration of technology-assisted screening and hearing aid technologies.
Main Results:
- High prevalence of hearing loss in dementia populations, especially in older adults.
- Association between hearing loss and increased neuropsychiatric symptoms.
- Low rates of hearing aid use (around 20%) among persons with dementia.
Conclusions:
- Hearing loss is a significant, often overlooked, condition in dementia care.
- Interventions like hearing aids may mitigate negative impacts.
- Practical assessment and management tools can be integrated into routine clinical practice.

01:24Chronic Kidney Disease II: Clinical Manifestations
516
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

295
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

433
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
