Summary
Computerized cognitive training (CCT) may modestly improve cognition and mood in individuals with mild cognitive impairment (MCI). However, current evidence does not show that brain games prevent dementia.
Area of Science:
- Neurology
- Gerontology
- Cognitive Science
Background:
- Commercialization of brain games prompts questions about their efficacy in preventing dementia.
- Mild Cognitive Impairment (MCI) is a critical stage where interventions may be beneficial.
Purpose of the Study:
- To review the effectiveness of computerized cognitive training (CCT) in older adults with MCI.
- To determine if CCT, including commercial brain games, can prevent dementia.
Main Methods:
- Systematic review of 15 unique studies identified from 11 review articles via PubMed and PsycINFO.
- Analysis focused on CCT interventions, particularly commercial brain games, in individuals with MCI.
Main Results:
- Nine of twelve studies showed significant improvements in episodic memory following CCT.
- Four of six studies indicated improvements in mood and/or anxiety after CCT.
- No significant outcome differences were observed between commercial brain games and investigator-designed CCT.
Conclusions:
- Computerized cognitive training, including commercial brain games, may offer modest benefits for cognition and mood in individuals with MCI.
- There is no direct evidence from this review that brain games or CCT can prevent dementia.
- Recommendations are provided for clinicians discussing brain games with patients experiencing MCI.

01:30Cognitive Development During Adulthood
954
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,...

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.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
696
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.

01:22Alzheimer's Disease: Treatment
1.0K
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...

01:26Alzheimer's Disease: Overview
1.8K
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...
