Dementia

633
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....

Esophageal Varices-II: Clinical Features and Management

702
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Drug Dosing: Geriatric Patients

335
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...

Area of Science:

  • Neurology
  • Geriatrics
  • Critical Care Medicine

Background:

  • Delirium is an acute confusional state with fluctuating mental status.
  • It is characterized by inattention, altered consciousness, and cognitive deficits.
  • Predisposing factors and stressors contribute to its development.

Purpose of the Study:

  • To define delirium and its core features.
  • To outline the contributing factors and triggers of delirium.
  • To categorize delirium based on psychomotor presentation.

Main Methods:

  • Literature review of delirium.
  • Clinical observation and case studies.
  • Analysis of diagnostic criteria and classifications.

Main Results:

  • Delirium presents with sudden onset and fluctuating course.
  • Key features include inattention, impaired arousal, and cognitive dysfunction.
  • Categorization into hyperactive, hypoactive, and mixed types based on psychomotor activity.

Conclusions:

  • Delirium is a distinct clinical syndrome requiring prompt recognition.
  • Understanding predisposing factors and stressors is crucial for management.
  • Psychomotor subtypes aid in clinical assessment and potential treatment strategies.
