Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

27
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

19
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Dissociative Disorders

25
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Personality Disorders: Paranoid and Schizoid

26
Personality disorders represent enduring cognition, affect, and behavior patterns that significantly deviate from societal norms. These maladaptive traits often lead to difficulties in various domains, including interpersonal relationships, occupational settings, and overall psychological well-being. Paranoid personality disorder and schizoid personality disorder are two distinct conditions marked by odd or eccentric behavior.

Traumatic Memory01:20

Traumatic Memory

72
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

349
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

科学领域:

  • 神经科学是一个神经科学.
  • 精神病学是一个精神病学.
  • 认知心理学 认知心理学

背景情况:

  • 以前的研究表明,在创伤后应激障碍 (PTSD) 中,注意力,记忆和执行功能存在认知缺陷.
  • 关于复杂PTSD (cPTSD) 损伤的认知特征和预测因素的理解有限,这是ICD-11新型诊断.
  • 这项研究通过比较cPTSD中的认知功能与非复杂PTSD (ncPTSD) 的认知功能来解决知识差距.

研究的目的:

  • 研究和比较被诊断患有cPTSD的个体的认知功能与ncPTSD.
  • 在cPTSD和ncPTSD人群中确定认知障碍的预测因素.
  • 增强对与cPTSD相关的特定认知缺陷的理解.

主要方法:

  • 64名参与者 (34名cPTSD,30名ncPTSD) 完成了心理测量问卷和认知基本评估 (COGBAT) 神经心理测试电池.
  • 评估的认知领域包括一般认知指数,注意力,视觉记忆和执行功能.
  • 统计分析包括将组结果与规范数据进行比较,独立样本对组差异进行t测试,以及用于预测因子识别的回归分析.

主要成果:

  • 无论是cPTSD还是ncPTSD组,相对于COGBAT标准样本,都显示出认知障碍.
  • 在视觉记忆 (p = .003) 和选择性注意力 (p = .004) 中观察到显著的群体差异,cPTSD 呈现出更大的缺陷.
  • 多变量回归显示,PTSD类型和年龄显著预测视觉记忆,而PTSD类型,年龄和精神药物药物影响了选择性注意力.

结论:

  • 这些发现强调了cPTSD中显著的认知障碍,特别是视觉记忆和选择性注意力.
  • 创伤后应激障碍的类型,年龄和精神药物药物成为这些认知缺陷的关键预测因素.
  • 对cPTSD的综合治疗计划应该考虑更密集和多样化的干预措施,如认知训练,以解决确定的症状严重程度和认知缺陷.
