Dementia

482
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: Treatment

744
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...

Alzheimer's Disease: Overview

1.6K
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...

Parkinson's Disease: Overview

1.7K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Area of Science:

  • Public Health
  • Gerontology
  • Health Informatics

Background:

  • Dementia poses a significant global health challenge, necessitating effective prevention strategies.
  • Modifiable risk factors and lifestyle changes can reduce dementia risk, yet public awareness is low.
  • Web-based platforms offer scalable solutions to disseminate crucial health information.

Purpose of the Study:

  • To evaluate the impact of the DementiaRisk.ca platform on dementia risk knowledge.
  • To assess changes in participants' intention to engage in risk-reduction behaviors.
  • To measure actual health behavior changes following platform exposure.

Main Methods:

  • A sequential explanatory mixed-methods design with 510 randomized participants (intervention vs. control).
  • Intervention group received DementiaRisk.ca (multimedia lesson, micro-learning emails); control received mild cognitive impairment information.
  • Outcomes (knowledge, intentions, behavior) measured at baseline, 4 weeks, and 12 weeks; qualitative feedback collected.

Main Results:

  • The intervention group showed significantly greater knowledge gains in dementia risk factors compared to the control group, persisting at 12 weeks.
  • Participants with lower education levels exhibited the most substantial knowledge improvements.
  • The DementiaRisk.ca platform led to significant and sustained improvements in health behaviors and intentions, with qualitative data indicating lifestyle changes.

Conclusions:

  • DementiaRisk.ca significantly enhances dementia risk knowledge and promotes behavior change, particularly in lower education demographics.
  • The platform demonstrates potential for reducing health inequities and improving public health outcomes in dementia prevention.
  • Future research should focus on optimizing engagement and expanding reach to diverse populations for long-term impact.
