Cognitive Dissonance

36.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

An Introduction to Cognition09:08

An Introduction to Cognition

23.8K
Cognition encompasses mental processes such as memory, perception, decision-making reasoning and language. Cognitive scientists are using a combination of behavioral and neuropsychological techniques to investigate the underlying neural substrates of cognition. They are interested in understanding how information is perceived, processed and how does it affect the final execution of behaviors. With this knowledge, researchers hope to develop new treatments for individuals with cognitive...

Area of Science:

  • Neuroscience
  • Oncology
  • Anesthesiology

Background:

  • Cognitive dysfunction is a frequent complication of primary and metastatic brain tumors.
  • Deficits manifest as problems with memory, attention, and information processing, significantly impacting quality of life.
  • Both the tumor itself and treatment modalities contribute to neurocognitive impairment.

Purpose of the Study:

  • To review the pathophysiology, risk factors, and assessment methods for cognitive dysfunction in brain tumor patients.
  • To provide an overview of the impact of anesthetics on postoperative cognitive dysfunction.
  • To discuss management strategies for cognitive deficits.

Main Methods:

  • Literature review of studies on brain tumors and cognitive function.
  • Analysis of pathophysiology and risk factors.
  • Examination of assessment tools and treatment outcomes.

Main Results:

  • Primary brain tumors are strongly linked to neurocognitive deficits.
  • Various treatment modalities can exacerbate cognitive impairment.
  • Anesthetics may play a role in postoperative cognitive dysfunction.

Conclusions:

  • Cognitive dysfunction is a significant challenge in brain tumor management.
  • Comprehensive assessment and tailored management strategies are crucial.
  • Further research is needed to optimize anesthetic protocols and mitigate cognitive decline.
