Physiological and Psychological Mechanisms of Attention-Deficit/Hyperactivity Disorder | Chapter 2 | Scientific Research, New Technologies and Applications Vol. 5

 

Background: Physiological mechanisms are the material basis of ADHD and the basis for ADHD drug treatment, and the psychological mechanism is the process of psychological changes that lead to ADHD. Physiological mechanisms interact with physiological mechanisms to jointly determine the development and outcome of ADHD. At present, the physiological and psychological mechanisms of ADHD have attracted increasing attention from the academic community, but there is still no consensus on many issues.

Objective: This article aims to provide a basis for the scientific development and implementation of comprehensive intervention measures for ADHD by reviewing the research progress on the physiological and psychological mechanisms of ADHD.

Methods: A literature search method was used to organize 46 influential articles, analyze the main physiological and psychological mechanisms of ADHD, explain their principles, functions, and research evidence, and point out the shortcomings of previous research based on this.

Results: The onset of ADHD involves various levels and aspects of physiological mechanisms such as changes in genes, blood components, brain structure, and damage to neural function development, as well as the core components of psychological mechanisms - the response inhibition deficiency.

Conclusion: Research on the physiological and psychological mechanisms of ADHD is becoming increasingly in-depth, but the application of research methods and techniques needs improvement.

A Theoretical Assumption of Atrial Fibrillation | Chapter 19 | New Horizons in Medicine and Medical Research Vol. 9

 The most common cardiac arrhythmia in clinical practise is atrial fibrillation (AF). Many research have been conducted to determine what causes AF to develop, but the issue has yet to be resolved. Based on the cessation of atrial mechanical systole, atrial fibrillation has lately been hypothesised as a protective physiological mechanism. In pathological conditions, this lowers the pressure in the pulmonary veins and alveolar capillaries, lowering the risk of pulmonary congestion and edoema. This hypothesis explains the link between left ventricle (LV) dysfunction and atrial fibrillation (AF), aids in the development of algorithms for the relationship between AF and LV dysfunction, as well as other diseases and conditions, suggests a new approach to locating the source of AF, and demonstrates the atriums' protective role in AF. the progression of LV dysfunction The idea is well-supported by known facts and phenomena relevant to AF. The proposed idea may provide insight into the progression of AF. In the pulmonary veins, each person has a defensive physiological system that is most likely genetically designed.

In clinical practise, atrial fibrillation (AF) is the most common arrhythmia, and it is commonly associated to LV dysfunction and heart failure (HF). It's been termed "the pandemic of the century." AF is a form of arrhythmia that is more frequent in the elderly and is becoming more common as the population ages. Aside from age, AF has been linked to a variety of cardiac and medical conditions. Hypertension, coronary artery disease, heart failure, valvular heart disease, and hyperthyroidism are all conditions that can lead to death.
