Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

105
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Binge Eating Disorders01:23

Binge Eating Disorders

65
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Revisionist Views of Adolescent and Adult Cognition

32
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Appendicitis-II: Diagnostic Studies and Management

80
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

84
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Summary
This summary is machine-generated.

Ten years after adolescent bariatric surgery, cognitive deficits in attention and executive function are common. Mild cognitive impairment (MCI) affects over half of young adults, particularly those with preoperative hypertension.

Area of Science:

  • Neuroscience
  • Adolescent Medicine
  • Bariatric Surgery Outcomes

Background:

  • Adolescent bariatric surgery leads to significant weight loss and improved comorbidities.
  • Adult studies suggest cognitive improvements post-surgery, but adolescent data, especially long-term, is limited.

Purpose of the Study:

  • To evaluate cognitive function in young adults 10 years after undergoing bariatric surgery during adolescence.

Main Methods:

  • Ninety-nine young adults, participants in the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study, completed a 10-year postoperative assessment.
  • A computerized cognitive test battery was administered to assess various cognitive domains.
  • Preoperative hypertension and surgical procedure type (Roux-en-Y gastric bypass) were analyzed as potential factors.

Main Results:

  • Cognitive dysfunction was prevalent, particularly in attention and executive function.
  • 30% showed deficits in Continuous Performance Test reaction time and Maze Errors.
  • 53.5% met criteria for mild cognitive impairment (MCI); preoperative hypertension and Roux-en-Y gastric bypass were associated with higher MCI likelihood.

Conclusions:

  • Cognitive deficits are common a decade after adolescent bariatric surgery.
  • Further research is required to understand persistence, underlying mechanisms, and potential mitigation strategies for these deficits.
