Dementia

636
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....

Drug Dosing: Geriatric Patients

339
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's Disease: Overview01:26

Alzheimer's Disease: Overview

1.9K
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

1.1K
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...

Focus Charting, also known as the focus charting system or "focus documentation," is a systematic documentation approach used in healthcare to organize patient information in medical records.
It typically involves three columns for recording information:

Summary

Delirium is a sudden change in mental status with fluctuating consciousness, mainly affecting attention. It presents with varied symptoms and can be categorized into hyperactive, hypoactive, or mixed types based on psychomotor activity.

Area of Science:

  • Neuroscience and Psychiatry
  • Critical Care Medicine
  • Geriatrics

Background:

  • Delirium is characterized by acute-onset, fluctuating changes in mental status and consciousness.
  • Key features include inattention, altered perception, and disorganized thinking.
  • Predisposing factors and stressors (e.g., brain insults, systemic illness, environmental changes) contribute to its development.

Purpose of the Study:

  • To define delirium, its core characteristics, and contributing factors.
  • To outline the varied presentations of delirium.
  • To categorize delirium based on psychomotor profiles.

Main Methods:

  • Review of existing literature and clinical definitions of delirium.
  • Analysis of symptomology, including attention deficits, altered consciousness, and cognitive impairments.
  • Classification of delirium subtypes based on observed psychomotor behavior.

Main Results:

  • Delirium presents as an acute confusional state with fluctuating severity.
  • Commonly associated with inattention, disorientation, and perceptual disturbances.
  • Identified three main psychomotor subtypes: hyperactive, hypoactive, and mixed.

Conclusions:

  • Understanding delirium's varied presentation is crucial for accurate diagnosis and management.
  • The hyperactive, hypoactive, and mixed classifications aid in clinical recognition.
  • Further research into underlying mechanisms and targeted interventions is warranted.
