Dementia in the elderly: the silent epidemic
Annals of Internal Medicine
|August 1, 1982
Summary
The aging population faces a growing dementia epidemic. Many cases of intellectual impairment in the elderly stem from treatable conditions, not just irreversible Alzheimer's disease.
Area of Science:
- Gerontology
- Neurology
- Public Health
Background:
- The aging of the American population is projected to increase the prevalence of dementia.
- Intellectual impairment in the elderly significantly impacts the healthcare system, especially long-term care.
- Distinguishing between dementia types, like Alzheimer's disease, and other treatable causes of cognitive decline is crucial.
Purpose of the Study:
- To provide comprehensive information on the causes, mechanisms, and clinical presentation of intellectual impairment in the elderly.
- To outline appropriate diagnostic laboratory studies and expected outcomes for various forms of elderly cognitive impairment.
- To highlight the need for recognizing and addressing treatable conditions associated with cognitive decline in older adults.
Main Methods:
- Review of existing literature on dementia and intellectual impairment in the elderly.
- Analysis of causes, physiopathologic mechanisms, and clinical manifestations.
- Discussion of diagnostic approaches and prognostic factors.
Main Results:
- Many conditions causing intellectual impairment in the elderly are ameliorable or curable.
- Cognitive decline can mimic irreversible brain diseases such as Alzheimer's disease.
- Early and accurate diagnosis is key to effective management.
Conclusions:
- Recognizing treatable causes of intellectual impairment is vital for the healthcare system.
- Advancements in understanding dementia's cause, pathogenesis, and treatment are anticipated.
- Future developments will improve laboratory diagnostics and therapeutic interventions for dementia.

01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:30Dementia
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
