Abstract

Insights

Individuals with mild cognitive impairment and early Alzheimer's disease want to participate in healthcare decisions but have impaired capacity. Relatives and physicians often misjudge these preferences and capacity levels, posing ethical challenges.

Area of Science:

  • Neuroscience
  • Geriatrics
  • Medical Ethics

Background:

  • Individuals with amnestic mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD) often face challenges in healthcare decision-making.
  • Understanding patient preferences and decisional capacity is crucial for ethical and effective care.

Purpose of the Study:

  • To analyze healthcare decision-making preferences in aMCI and mild AD patients.
  • To correlate these preferences with measures of decisional capacity.
  • To explore the perspectives of relatives and referring physicians on patient involvement.

Main Methods:

  • A cross-sectional survey was conducted at a university-based memory clinic.
  • One hundred patients with aMCI or mild AD, 99 relatives, and 93 physicians participated.
  • Data collected included participation preferences, decisional capacity, and assessments by relatives and physicians.

Main Results:

  • Patients expressed a strong preference for participating in healthcare decisions, particularly social aspects, desiring a secondary role for relatives.
  • Relatives and physicians inaccurately predicted patient preferences and tended to underestimate patients' desired decision-making power.
  • Lower Mini-Mental State Examination scores and uncertainty about decisional capacity correlated with reduced patient participation; deficits were noted in understanding information.

Conclusions:

  • The study highlights a significant ethical and practical challenge due to the discrepancy between strong participation preferences and impaired decisional capacity in aMCI and early AD.
  • Implementing structured assessments of decisional capacity and decision-making support interventions is recommended to address these challenges.

Alzheimer's Disease: Treatment

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: Overview01:26

Alzheimer's Disease: Overview

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 and tau...
Alzheimer Disease l: Introduction01:29

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Drug Dosing: Geriatric Patients

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...

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
Dementia l: Introduction01:22

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...
