Summary
Dementia, a condition affecting memory and intellectual abilities, has Alzheimer disease as its most common form. Research explores risk and protective factors for dementia, including Alzheimer disease.
Area of Science:
- Neurology
- Gerontology
- Public Health
Background:
- Dementia is characterized by memory impairment and cognitive decline, impacting daily life.
- Alzheimer disease represents 50-70% of all dementia cases.
- The exact causes of dementia remain unknown, but risk and protective factors are recognized.
Purpose of the Study:
- To review potential risk factors for dementia and Alzheimer disease.
- To identify protective factors that may prevent dementia development.
- To discuss challenges in creating a dementia risk index.
Main Methods:
- Literature review of existing studies on dementia risk and protective factors.
- Analysis of factors associated with Alzheimer disease development.
- Exploration of methodologies for risk index construction.
Main Results:
- Identified various lifestyle, genetic, and environmental risk factors for dementia.
- Highlighted protective factors such as cognitive engagement and healthy habits.
- Discussed the complexity and limitations in quantifying dementia risk.
Conclusions:
- Understanding risk and protective factors is crucial for dementia prevention strategies.
- Further research is needed to refine dementia risk assessment tools.
- Developing a comprehensive dementia risk index faces significant challenges.

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...
01:22Dementia 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...
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...

01:22Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
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...
