Dementia l: Introduction01:22

Dementia l: Introduction

31
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...

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

46
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Dementia

686
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....

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

1.3K
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Alzheimer Disease l: Introduction01:29

Alzheimer Disease l: Introduction

20
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...

Dissociative Disorders01:27

Dissociative Disorders

1.1K
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...

Area of Science:

  • Geriatrics
  • Neurology
  • Critical Care Medicine

Background:

  • Delirium in older patients is linked to persistent functional and cognitive deficits.
  • Hypoactive delirium is frequently underdiagnosed or misidentified by healthcare providers.
  • Screening tools aid in the detection of patients experiencing delirium.

Purpose of the Study:

  • To highlight the significance of recognizing and managing delirium in the elderly.
  • To emphasize the multifactorial etiology and preventive strategies for delirium.
  • To outline appropriate diagnostic and therapeutic approaches for suspected delirium.

Main Methods:

  • Literature review on delirium in older adults.
  • Analysis of diagnostic challenges, particularly for hypoactive delirium.
  • Evaluation of non-pharmacological and pharmacological treatment strategies.

Main Results:

  • Delirium is associated with long-term cognitive and functional impairments.
  • A multifactorial model, considering predisposing and precipitating factors, best explains delirium etiology.
  • Non-pharmacological interventions are crucial for managing behavioral symptoms.

Conclusions:

  • Prompt diagnosis and treatment of precipitating conditions are vital upon suspicion of delirium.
  • Non-pharmacological interventions, such as environmental modifications, are important for managing delirium symptoms.
  • Pharmacological interventions should be reserved for severe cases unresponsive to non-pharmacological approaches.
