Summary
Experiencing age discrimination is linked to worse cognitive function and increased dementia risk in older Koreans. Addressing ageism is crucial for public health and cognitive preservation.
Area of Science:
- Gerontology
- Public Health
- Cognitive Science
Background:
- Previous research links perceived age discrimination to psychological risks.
- Its role in cognitive health, particularly cognitive decline in older adults, remains under-explored.
Purpose of the Study:
- To examine the association between perceived age discrimination and cognitive function in older Koreans.
- To address cognitive decline as a significant public health concern.
Main Methods:
- Utilized data from 9885 adults aged ≥65 years from the 2020 National Survey of Living Conditions and Welfare Needs of Older Koreans.
- Assessed perceived age discrimination using seven yes/no questions and cognitive function via the Mini-Mental State Examination for Dementia Screening.
- Employed chi-squared tests, t-tests, hierarchical multiple regression, and logistic regression analyses.
Main Results:
- 40.5% of participants reported experiencing age discrimination in the past year.
- Perceived age discrimination was significantly associated with poorer cognitive function (p < 0.001).
- Significant association found with greater odds of cognitive impairment suggestive of dementia (OR = 1.174, p < 0.001).
Conclusions:
- Addressing societal ageism is vital for maintaining cognitive function in later life.
- Highlights the need for public health interventions and policies targeting ageism.
- Ageism is identified as a potentially modifiable psychosocial factor in preventing cognitive impairment.

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
308
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

02:55Stereotypes, Prejudice, and Discrimination
95.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

01:30Cognitive Development During Adulthood
1.1K
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,...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
788
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

305
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

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...
