Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

4.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes Mellitus: Overview and Type I Subtype

5.0K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

994
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Piaget's Stage 2 of Cognitive Development

883
The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...

Cognitive Dissonance01:38

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...

Self-Concept01:19

Self-Concept

1.6K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Summary

Cognitive dysfunction in type 2 diabetes mellitus (T2DM) involves subtle cognitive decline and brain changes. This impacts diabetes self-management and increases hypoglycemia risk.

Area of Science:

  • Neurology
  • Endocrinology
  • Psychology

Background:

  • Cognitive dysfunction is linked to type 2 diabetes mellitus (T2DM) but lacks a clear definition.
  • Understanding this relationship is crucial for patient care and management strategies.

Purpose of the Study:

  • To define the concept of cognitive dysfunction in individuals with T2DM.
  • To examine its defining attributes, antecedents, and consequences.

Main Methods:

  • Systematic literature search of PubMed, CINAHL, and PsycINFO databases from 2008 to 2018.
  • Concept analysis of 37 included studies.

Main Results:

  • Defining attributes include: unrecognized symptom, subtle decline in cognitive domains, and structural brain changes.
  • A major antecedent is diabetes-related pathological changes.
  • Consequences involve impaired diabetes self-management, nonadherence, and increased hypoglycemia risk.

Conclusions:

  • This concept analysis offers a theoretical framework for evaluating and intervening in T2DM-related cognitive dysfunction.
  • It highlights the need for recognizing and addressing cognitive changes in T2DM patients.
