Dementia01:30

Dementia

142
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: Overview01:26

Alzheimer's Disease: Overview

530
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...

Alzheimer's Disease: Treatment

222
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...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

160
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Intellectual Disability01:29

Intellectual Disability

120
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

12.7K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Area of Science:

  • Neuroscience and Public Health
  • Gerontology and Social Epidemiology

Background:

  • Brain health depends on rich physical and social environments.
  • Disabling environments elevate dementia risk, yet research focuses on individual health behaviors.
  • The current emphasis on 'lifestyle' is ethically questionable and insufficient for dementia prevention.

Purpose of the Study:

  • To highlight deprivation as an overlooked dementia risk factor.
  • To advocate for a shift in dementia prevention strategies from individual behaviors to societal factors.
  • To emphasize the need for upstream interventions addressing inequalities.

Main Methods:

  • Literature review on environmental deprivation and dementia risk.
  • Analysis of current dementia risk reduction research and policy.
  • Ethical and therapeutic critique of lifestyle-centric approaches.

Main Results:

  • Deprivation, encompassing social and physical environmental factors, is an independent dementia risk.
  • Existing research and policy disproportionately focus on individual health behaviors.
  • A focus on lifestyle modification without addressing underlying deprivations is inadequate.

Conclusions:

  • Dementia prevention guidelines must incorporate deprivation as a key risk factor.
  • Fairer societal structures are essential for reducing dementia risk.
  • Interventions must support individuals, acknowledging that 'no ought without support'.
