Cognitive Development During Adulthood

Cognitive Development During Adulthood

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

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

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. They...

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Dementia

Dementia

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.

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

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 and tau...

Alzheimer's Disease: Treatment

Alzheimer's Disease: Treatment

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...

Area of Science:

Gerontology and Cognitive Neuroscience
Dementia Care Research

Background:

Limited research exists on non-pharmacological interventions for dementia cognitive enhancement with a guiding framework.
The Progressive Lowered Stress Threshold (PLST) model is recognized for predicting dementia-related behavioral issues.
An expanded model is proposed, integrating the PLST model with findings on anxiety, depression, and cognitive function.

Purpose of the Study:

To propose a conceptual framework for interventions designed to improve cognitive function in people with dementia.
To guide the development of non-pharmacological strategies for dementia cognitive enhancement.

Main Methods:

A discursive paper approach was utilized.
Literature on stress and anxiety in dementia was reviewed and critically analyzed.
An expanded model was developed by integrating reviewed literature into the PLST model.

Main Results:

An expanded conceptual model is proposed for guiding non-pharmacological interventions in dementia care.
The model considers the relationships between stress, anxiety, depression, and cognitive function in dementia patients.
The proposed model offers a framework for developing interventions to promote cognitive functions.

Conclusions:

The biomedical, behavioral, and PLST models are common in dementia care, each with limitations.
The proposed expanded model offers advantages in guiding intervention development for dementia.
Further empirical testing of the proposed model is recommended to validate its efficacy in enhancing cognitive function and improving well-being for dementia patients and their caregivers.
