Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

224
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

161
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 Tissues

2.3K
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...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

644
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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

196
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Dementia01:30

Dementia

159
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....

Area of Science:

  • Gerontology
  • Cognitive Neuroscience
  • Behavioral Science

Background:

  • Aging is associated with decreased physical activity, potentially due to reduced energy availability and cognitive function.
  • The interplay between subjective energy availability, cognitive function, and physical activity in older adults remains unclear.

Purpose of the Study:

  • To investigate the moderating role of cognitive functions on the relationship between subjective energy availability and physical activity in aging adults.
  • To explore how cognitive functions influence physical activity engagement across different age groups.

Main Methods:

  • Utilized data from 104,590 adults across 21 European countries (Survey of Health, Ageing and Retirement in Europe).
  • Assessed cognitive functions via verbal fluency and delayed recall tests.
  • Analyzed self-reported physical activity and subjective energy availability using linear mixed-effects models.

Main Results:

  • Cognitive functions significantly moderated the association between subjective energy availability and physical activity.
  • Cognitive functions became critical for maintaining physical activity in older adults, irrespective of perceived energy levels.
  • Findings were robust across sensitivity and robustness analyses.

Conclusions:

  • Cognitive functions may enable older adults to sustain physical activity even with perceived insufficient energy.
  • The importance of cognitive functions for physical activity engagement intensifies with advanced age, offering a protective effect regardless of energy status.
