Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...

Dementia

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.
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...

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 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...
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...

Summary

Aggression in dementia patients is common and can be prevented. Primary care physicians can screen for and treat factors like depression and pain to manage behavioral symptoms without medication.

Area of Science:

  • Geriatrics
  • Neurology
  • Psychiatry

Background:

  • Non-cognitive symptoms, including aggression, are prevalent in individuals with dementia.
  • Aggression poses risks to both patients and caregivers.
  • Factors such as depression, pain, caregiver burden, and relationship quality influence aggression.

Purpose of the Study:

  • To provide primary care physicians with practical strategies for preventing aggression in dementia patients.
  • To highlight the importance of nonpharmacological interventions.
  • To guide physicians in screening for and treating predictive factors of aggression.

Main Methods:

  • Review of clinical factors contributing to aggression in dementia.
  • Discussion of assessment instruments for identifying risk factors.

  • Outline of nonpharmacological treatment options and referral pathways.

    • Main Results:

    • Identifying and managing depression, pain, and caregiver burden can reduce aggression.
    • A positive caregiver-patient relationship is protective.
    • Nonpharmacological approaches are recommended before considering medication.

    Conclusions:

    • Primary care physicians can play a crucial role in preventing dementia-related aggression.
    • Screening for and addressing contributing factors is key to effective management.
    • Nonpharmacological interventions offer a safer alternative for managing behavioral symptoms.
