Dementia

412
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: Overview

1.4K
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...

Alzheimer's Disease: Treatment

635
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...

Drug Dosing: Geriatric Patients

131
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Parkinson's Disease: Overview

1.5K
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...

Psychosis: Goals of Pharmacotherapy

356
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Area of Science:

  • Medical ethics
  • Geriatric medicine
  • Infectious disease epidemiology

Background:

  • Hospitals face surges in coronavirus disease 19 (COVID-19) patients, straining intensive care units.
  • Mechanical ventilators and other life-saving resources may become scarce.
  • Older adults are at higher risk for severe COVID-19, and dementia is a common comorbidity.

Purpose of the Study:

  • To provide ethical guidance for triaging patients with dementia to scarce medical resources during the COVID-19 pandemic.
  • To address the vulnerability of individuals with dementia in critical care allocation decisions.
  • To support healthcare providers in making difficult resource allocation choices.

Main Methods:

  • Development of ethical recommendations by a task force commissioned by the Alzheimer Society of Canada.
  • Review of existing ethical frameworks for resource allocation in public health emergencies.
  • Consideration of the specific needs and vulnerabilities of persons with dementia.

Main Results:

  • The commentary offers a framework for prioritizing care for individuals with dementia when resources are limited.
  • It emphasizes the importance of considering the unique needs of persons with dementia in triage protocols.
  • Guidance is provided to ensure equitable and ethical distribution of critical care resources.

Conclusions:

  • Ethical triage protocols are essential for managing scarce resources during the COVID-19 pandemic.
  • Special consideration must be given to vulnerable populations, such as those with dementia.
  • This guidance aims to support fair and compassionate decision-making in critical care allocation.
