Summary
Cognitive stimulation shows mixed results for non-memory led dementias like Parkinson's disease dementia. More research is needed to adapt these interventions for diverse dementia profiles.
Area of Science:
- Neuroscience
- Gerontology
- Cognitive Psychology
Background:
- Cognitive stimulation is a non-pharmacological strategy to enhance cognitive and social functions in individuals with dementia.
- Non-memory led dementias present unique challenges for cognitive and social support.
- Adapting interventions is crucial for individuals with primary symptoms beyond memory impairment.
Purpose of the Study:
- To review the feasibility of cognitive stimulation for non-memory led dementias.
- To assess adaptations of cognitive stimulation for specific non-memory led dementia symptoms.
- To identify research gaps in this area.
Main Methods:
- A scoping review was conducted.
- Searched five major academic databases (PsycINFO, MedLINE, EMBASE, Web of Science, Cinhal Plus).
- Included studies focused on cognitive stimulation in non-memory led dementias.
Main Results:
- Eight studies met the inclusion criteria, primarily focusing on Parkinson's related dementia (7 studies) and posterior cortical atrophy (1 study).
- Six studies reported on cognitive stimulation effects on cognition and mood, yielding mixed findings.
- Interventions and findings were limited by small sample sizes.
Conclusions:
- Evidence for cognitive stimulation in non-memory led dementias is limited, with adaptations mainly for Parkinson's related dementia.
- Future research should explore adaptations for other non-memory led dementias (e.g., posterior cortical atrophy, frontotemporal dementia, primary progressive aphasia).
- Involving patients, caregivers, and professionals is key to tailoring interventions for diverse cognitive needs.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
85
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.

01:26Alzheimer's Disease: Overview
323
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...

01:22Alzheimer's Disease: Treatment
128
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...

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.

01:30Dementia

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 Development During Adulthood
28
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,...
