Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

21
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,...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

84
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

63
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....

Learning Disabilities01:25

Learning Disabilities

64
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Working Memory01:24

Working Memory

82
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

228
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Area of Science:

  • Gerontology
  • Neuroscience
  • Rehabilitation Science

Background:

  • Mild cognitive impairment (MCI) affects cognition, but its impact on daily functionality is not well understood.
  • Digital cognitive training is a potential intervention for MCI, yet its functional benefits require further definition.

Purpose of the Study:

  • To evaluate the impact of digital cognitive training on the functional performance of individuals with MCI.
  • To compare the effectiveness of digital cognitive training against an active control using the Canadian Occupational Performance Measure (COPM).

Main Methods:

  • A double-blinded, randomized, stepped wedge clinical trial involving participants aged 60+ with MCI.
  • Intervention involved 10 hours of digital cognitive training versus a control group playing commercial computer games.
  • Functionality and cognition were assessed pre- and post-intervention using the COPM.

Main Results:

  • Ten hours of digital cognitive training led to significant improvements in functionality, as measured by COPM performance, compared to the active control.
  • Participants in the digital cognitive training group showed significant improvements in learning over trials.
  • The COPM proved to be a sensitive tool for detecting functional changes in this population.

Conclusions:

  • Digital cognitive training demonstrates efficacy in improving functional performance in individuals with MCI.
  • The Canadian Occupational Performance Measure (COPM) is a valuable tool for assessing functional outcomes in MCI interventions.
  • Further research should utilize sensitive instruments like the COPM to evaluate therapeutic interventions for functional deficits in MCI.
