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.

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...

Medical Education
Public Health

Background:

Virtual reality (VR) shows promise for training healthcare professionals in Alzheimer disease and related dementias (ADRD) care.
Limited research exists on VR's use for public awareness of ADRD.

Purpose of the Study:

To assess the impact of the VR video "A Walk-Through Dementia" on YouTube users.
To analyze viewer engagement and understanding of ADRD through comments on a VR experience.

Main Methods:

Collected 12,754 YouTube comments from the "A Walk-Through Dementia" VR video series.
Employed topic modeling and BERT embeddings to analyze comment themes and viewer reactions.
Utilized part-of-speech tagging to categorize frequent words and refine topic analysis.

Main Results:

Five key themes emerged from comment analysis, with personal experiences of ADRD's impact being predominant.
Other themes included positive reactions to VR, challenges of ADRD, caregiver roles, and learning outcomes.
Topic modeling identified user engagement with the immersive VR experience of ADRD.

Conclusions:

VR applications are effective experiential learning tools for enhancing public understanding of life with ADRD.
VR on social media platforms can significantly broaden outreach and knowledge dissemination about ADRD.
Further exploration of VR in public health campaigns for ADRD is recommended.
