Summary
This summary is machine-generated.Delusional memories in intensive care unit (ICU) patients are linked to post-traumatic stress disorder (PTSD) symptoms. Female sex, deep sedation, delirium, and longer ICU stays influence memory formation and PTSD development.
Area Of Science
- Critical Care Medicine
- Neuroscience
- Psychiatry
Background
- Intensive care unit (ICU) stays can lead to memory disturbances.
- Post-traumatic stress disorder (PTSD) is a significant concern for ICU survivors.
Purpose Of The Study
- Identify factors influencing memory formation in ICU patients.
- Examine the link between ICU memories and PTSD symptom development and progression.
Main Methods
- 426 adult ICU patients were interviewed using the ICU-Memory Tool (ICU-MT) at 3 months post-ICU.
- PTSD symptoms were assessed using the Impact of Event Scale (IES-6) at 3 and 12 months.
Main Results
- 47.7% had factual memories, 13.8% complete amnesia, and 38.5% delusional memories.
- Female sex and deep sedation correlated with amnesia; delirium and longer ICU stay correlated with delusional memories.
- Delusional memories were independently associated with increased PTSD symptoms at 3 and 12 months.
Conclusions
- Female sex and prolonged deep sedation are linked to ICU amnesia.
- Longer ICU stays and delirium are associated with delusional memories.
- Delusional memories strongly predict the development and persistence of PTSD symptoms, suggesting interventions are needed.

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...
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 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...
A flashbulb memory is a highly vivid and detailed memory, often linked to events of significant emotional impact. These memories stand out in contrast to everyday memories due to their clarity and the precision with which they are recalled. The strong emotions associated with the event act as a catalyst, ensuring that specific details, such as one's location, actions, and even peripheral elements, are etched into memory with remarkable accuracy. For example, many people can vividly recall...
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
