Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
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...

Alterations in Respiration II

1.8K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Altered States of Awareness

1.1K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Alterations in Blood Pressure

2.2K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Microbial Morphologies

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

Area of Science:

  • Neuroscience
  • Neurology

Background:

  • Multiple system atrophy (MSA) is a progressive neurodegenerative disease affecting adults.
  • Clinical diagnosis relies on motor and non-motor symptoms like autonomic dysfunction.
  • Cognitive dysfunction is prevalent in MSA but not part of current diagnostic criteria.

Purpose of the Study:

  • To review brain morphological changes in MSA patients.
  • To identify brain regions associated with cognitive impairment in MSA.
  • To provide a basis for including cognitive dysfunction in MSA diagnosis.

Main Methods:

  • Review of neuroimaging studies.
  • Analysis of neuropathological findings.
  • Examination of neuropsychological assessments.

Main Results:

  • Summarized morphological brain changes in MSA patients.
  • Discussed brain regions implicated in MSA-related cognitive impairment.
  • Highlighted the discrepancy between MSA's cognitive impact and diagnostic criteria.

Conclusions:

  • Cognitive dysfunction is a significant feature of MSA.
  • Brain morphological changes correlate with cognitive deficits.
  • Incorporating cognitive dysfunction into MSA diagnostic criteria is warranted.
