Dementia01:30

Dementia

619
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....

Pharmacodynamics in Geriatric Patients: Effects of Age

288
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...

Drug Dosing: Geriatric Patients

328
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...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

1.0K
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,...

Aging

917
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Area of Science:

  • Gerontology
  • Cognitive Neuroscience
  • Psychology

Background:

  • A younger subjective age is linked to successful aging, better health, and cognition.
  • Dementia may alter subjective age perception, but anosognosia and positive self-reporting could mask effects.

Purpose of the Study:

  • To compare subjective age ratings between individuals with and without dementia.
  • To investigate the impact of dementia on the subjective experience of aging.

Main Methods:

  • Cross-sectional study design.
  • Data collected from two samples in France and the United States.
  • Comparison of subjective age ratings between individuals with and without dementia, controlling for covariates.

Main Results:

  • Individuals with dementia reported feeling younger than their chronological age.
  • No significant differences in subjective age were found between individuals with and without dementia.
  • These findings persisted after controlling for sex, chronological age, education, and self-rated health.

Conclusions:

  • There are no substantial differences in the subjective experience of age between healthy individuals and those with dementia.
  • Subjective age perception may be resilient to the effects of dementia, or masked by other factors.
