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.

Environmental factors like noise and temperature significantly impact agitation in older adults with cognitive impairment. Optimizing indoor environments may help reduce agitation and improve quality of life for individuals with dementia.

Area of Science:

  • Gerontology
  • Environmental Health
  • Behavioral Science

Background:

  • Agitation is a common and distressing behavior in older adults with cognitive impairment.
  • Environmental modifications are recommended as first-line, non-pharmacological treatments for agitation.
  • The MODERATE study investigated environmental and behavioral precipitants of agitation.

Purpose of the Study:

  • To identify environmental factors that precipitate agitation in older adults with cognitive impairment.
  • To assess the relationship between indoor environmental quality and agitation levels.
  • To inform non-pharmacological interventions for managing agitation.

Main Methods:

  • Recruited older adults with cognitive impairment and their family caregivers in the Portland, Oregon area.
  • Collected weekly agitation data using the Cohen-Mansfield Agitation Inventory-Short Form.
  • Measured indoor environmental parameters (noise, temperature, air quality) using the Awair Omni device.

Main Results:

  • Noise, overall environmental quality score (Awair Score), and temperature were significantly associated with agitation levels.
  • Decreasing effect sizes were observed for noise, Awair Score, and temperature.
  • Data from 10 dyads were analyzed over a mean period of 52.6 weeks.

Conclusions:

  • Multiple indoor environmental quality parameters are linked to agitation in people living with cognitive impairment.
  • Holistic improvements in air quality and other environmental features warrant investigation.
  • Environmental modifications may be a key strategy to mitigate agitation.
