Dementia l: Introduction01:22

Dementia 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...
Dementia01:30

Dementia

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.
Alzheimer's Disease: Treatment01:22

Alzheimer'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...

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:
Alzheimer's Disease: Overview01:26

Alzheimer'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...
Alzheimer Disease l: Introduction01:29

Alzheimer 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...

Summary

As populations age, dementia prevalence rises. Recent studies explore cognitive training and physical activity as promising preventive strategies against cognitive decline and dementia onset, particularly Alzheimer's disease.

Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Dementia prevalence and incidence are increasing globally due to demographic aging.
  • Current anti-dementia medications offer limited benefits in cognitive and functional improvement.
  • There is a growing need for effective preventive strategies to combat cognitive decline and dementia.

Observation:

  • This paper reviews recent research on interventions aimed at dementia prevention.
  • Focus is placed on strategies targeting cognitive decline and the potential onset of dementia.
  • Alzheimer's disease is a primary area of interest within dementia prevention research.

Findings:

  • Cognitive training has shown potential in maintaining cognitive function.
  • Physical activity interventions are being investigated for their neuroprotective effects.

  • Combined strategies may offer synergistic benefits for dementia prevention.

    • Implications:

    • Preventive strategies like cognitive training and physical activity could mitigate the growing burden of dementia.
    • These interventions may offer a viable approach to delaying or preventing dementia onset, including Alzheimer's disease.
    • Further research is warranted to optimize and implement these strategies in at-risk populations.
