Introduction to Psychological Disorders

96
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Freudian Psychology

592
Sigmund Freud, an Austrian neurologist born in 1856, significantly influenced psychology through his exploration of the unconscious mind. His interest in patients suffering from hysteria and neurosis — conditions without apparent physical causes — led him to theorize the existence of an unconscious mind, a repository for feelings and urges beyond our awareness. Freud's innovative approach included techniques such as dream analysis, free association, and attention to slips of the...

Diagnostic and Statistical Manual of Mental Disorders (DSM)

35
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

43
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

概括

mitra环状断裂 (MAD) 是一种结构异常,有时在 mitra 门缩 (MVP) 中可见. 虽然MAD通常是良性的,但MVP患者的MAD可能会增加心律失常和突然心脏死亡 (SCD) 的风险.

科学领域:

  • 心脏病学 心脏病学
  • 心脏成像 - - 心脏成像
  • 电子生理学 电子生理学

背景情况:

  • 密特拉脱落 (MVP) 影响约3%的人,通常是良性的.
  • 一小部分MVP患者有严重吐,心律失常或突然心脏死亡 (SCD) 的风险.
  • 伴心环状断裂 (MAD) 是伴心环与心肌的分离,正在作为恶性MVP的潜在标志物进行研究.

研究的目的:

  • 探索中环断节 (MAD) 与中膜缩 (MVP) 的不良结果之间的关联.
  • 澄清MAD的诊断挑战和临床意义,特别是与心律失常和SCD相关.

主要方法:

  • 对心声回声学,3D心声回声学,心脏MRI和CT用于MAD诊断的审查.
  • 对在正常心脏和MVP患者中研究MAD的研究分析.
  • 检查有关MAD在心律失常和SCD中的作用的假设.

主要成果:

  • 在正常的心脏中观察到MAD,通常是良性后侧环变体.
  • 在MVP患者中,MAD,特别是在小册子冗余的情况下,与心律失常和SCD风险增加有关.
  • 在SCD中MAD的确切因果作用仍然不确定,可能是一个相关的发现,而不是直接的原因.

结论:

  • 伴心环状断裂 (MAD) 不仅仅是病理MVP,而且可以是良性发现.
  • 然而,MAD在MVP的背景下需要进一步调查,因为它与心律失常和突然心脏死亡有关.
  • 先进的成像技术有助于理解MAD,但其在致命性心律失常中确定的作用需要更多的研究.
