Community Based Intervention01:30

Community Based Intervention

258
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Alzheimer's Disease: Treatment

752
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...

Dementia01:30

Dementia

486
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....

Intellectual Disability01:29

Intellectual Disability

595
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Alzheimer's Disease: Overview01:26

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: Treatment01:24

Parkinson's Disease: Treatment

940
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Area of Science:

  • Gerontology
  • Public Health
  • Health Disparities

Background:

  • Dementia care interventions often overlook disparities faced by underserved populations.
  • Sexual and gender minority (SGM) adults with dementia experience unique challenges.
  • The Innovations in Dementia Empowerment and Action (IDEA) intervention was developed to address these gaps.

Purpose of the Study:

  • To compare the efficacy of the culturally tailored IDEA intervention against a standard intervention (s-RDAD) for SGM adults with dementia and their care partners.
  • To evaluate the impact of both interventions on physical activity, quality of life, physical functioning, and resource literacy.

Main Methods:

  • A 2-arm, single-blind, randomized controlled trial (RCT) involving 161 dyads (person with dementia/care partner).
  • Staggered multiple baseline design comparing IDEA and s-RDAD.
  • Outcomes assessed at post-treatment, and 30 and 56-week follow-ups.

Main Results:

  • IDEA care partners showed significantly higher community resource literacy at 30 weeks.
  • Both interventions improved physical activity and quality of life for individuals with dementia post-treatment.
  • IDEA demonstrated sustained improvements in physical activity and quality of life at 30 weeks, unlike s-RDAD.

Conclusions:

  • The culturally tailored IDEA intervention is efficacious and demonstrates sustained benefits.
  • Cultural tailoring of dementia interventions holds promise for reducing health disparities.
  • Further research is needed to translate IDEA into broader community settings.
