The Availability Heuristic01:08

The Availability Heuristic

6.1K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

20
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...

Alzheimer Disease l: Introduction

10
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...

Dementia l: Introduction

12
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 Disease ll: Pathophysiology

10
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...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

1.7K
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...

Summary
This summary is machine-generated.

Chronic traumatic encephalopathy (CTE) in sports is a neurodegenerative disease with a long history. Current public perception of CTE may be influenced by cognitive biases, diverging from scientific evidence.

Area of Science:

  • Neuroscience
  • Sports Medicine
  • Neuropathology

Background:

  • Chronic traumatic encephalopathy (CTE) has been recognized in athletes for over 85 years.
  • Recent years have seen a significant increase in media and scientific attention towards CTE in sports.
  • A notable gap exists between public understanding of CTE and current scientific data.

Observation:

  • The "availability cascade" cognitive bias may explain the discrepancy between public perception and scientific evidence regarding CTE.
  • This review examines the historical context of CTE in sports.
  • Recent epidemiological and autopsy studies on CTE are discussed.

Findings:

  • The review synthesizes the existing evidence base for CTE in sports.
  • It highlights the need to reconcile public perception with scientific findings.

Implications:

  • Understanding the history and evidence is crucial for accurate public discourse on CTE.
  • Recommendations are provided for future research directions in sports-related CTE.
  • Addressing cognitive biases is important for informed public and scientific engagement with CTE.
