Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

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, are a...
Beck's Cognitive Therapy01:25

Beck's Cognitive Therapy

Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Traumatic Memory01:20

Traumatic Memory

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 remembers mundane...
Dissociative Identity Disorder01:30

Dissociative Identity Disorder

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 Disorders01:27

Dissociative Disorders

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.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...
Psychological Responses to Stress01:20

Psychological Responses to Stress

Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Area of Science:

  • Psychology
  • Neuroscience
  • Psychiatry

Background:

  • Posttraumatic stress disorder (PTSD) is associated with various cognitive deficits.
  • Understanding these cognitive alterations is crucial for effective treatment.

Purpose of the Study:

  • To review and evaluate research on cognitive difficulties in PTSD.
  • Focus on studies published from January 2007 to June 2008.

Main Methods:

  • Systematic literature review.
  • Analysis of research on memory, attention, and appraisal in PTSD.

Main Results:

  • Individuals with PTSD exhibit memory impairments (verbal, autobiographical) and attentional biases toward trauma-related stimuli.
  • These deficits may be risk factors for PTSD, not solely consequences.
  • Traumatic memories in PTSD exist on a continuum with other memories.

Conclusions:

  • Cognitive alterations in PTSD range from general memory issues to specific cue difficulties.
  • These cognitive problems are linked to PTSD development and maintenance.
  • Further research is needed to clarify underlying mechanisms and the role of comorbid depression.
