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...

Summary
This summary is machine-generated.

Digital surveys show subtle differences in mild cognitive impairment (MCI) detection among Hispanic/Latinx adults. Lower survey completion and longer completion times in MCI may indicate early functional changes.

Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Alzheimer's disease and related dementias (AD/ADRD) disproportionately affect underserved populations, including Hispanic/Latinx adults.
  • Cognitive and functional changes in this demographic remain understudied.
  • The COMPADRE-CART study utilizes home-based technology to monitor health and activity in Hispanic/Latinx adults.

Purpose of the Study:

  • To examine differences in home-based activity patterns between cognitively unimpaired (CU) and mild cognitive impairment (MCI) Hispanic/Latinx adults.
  • To compare weekly digital survey completion metrics and responses between CU and MCI groups at baseline.

Main Methods:

  • Recruited Hispanic/Latinx participants aged 62+ from South Texas.
  • Utilized home-based technology including room sensors and wrist-worn actigraphs for activity monitoring.
  • Collected self-reported data via weekly digital surveys (Qualtrics) and clinical assessments (UDS 3).

Main Results:

  • No significant differences in daily activity patterns (steps, sleep, time outside home) were observed between CU and MCI groups.
  • Participants with MCI exhibited lower weekly survey completion rates and longer survey completion times.
  • MCI group reported higher pain levels, but other self-reported health events were similar across groups.

Conclusions:

  • Weekly digital questionnaire metrics show potential for detecting subtle functional differences in Hispanic/Latinx adults with MCI.
  • Longitudinal monitoring of these digital metrics may predict future cognitive decline.
