Can PTSD Occur with Amnesia for the Precipitating Event?
Cognitive Neuropsychiatry
|August 1, 1996
Summary
This case study shows that post-traumatic stress disorder (PTSD) can develop even after a severe head injury, challenging the idea that traumatic brain injury and PTSD are mutually exclusive.
Area of Science:
- Neuroscience
- Psychiatry
- Trauma Studies
Background:
- Theoretical models of PTSD emphasize memory of the precipitating event.
- Some research suggests traumatic brain injury (TBI) and PTSD are mutually exclusive.
Purpose of the Study:
- To examine a case challenging the notion that TBI and PTSD are mutually exclusive.
- To discuss the implications of this case for PTSD development theories.
Main Methods:
- Case study of an individual with severe head injury.
- Assessment of amnesia (retrograde and post-traumatic).
- Evaluation of anxiety symptoms six months post-accident.
Main Results:
- The individual experienced a two-day retrograde amnesia and a four-week post-traumatic amnesia.
- Six months after the injury, the individual exhibited symptoms consistent with PTSD, including nightmares and intrusive thoughts.
Conclusions:
- Severe head injury does not preclude the development of PTSD.
- This case challenges existing theories that view TBI and PTSD as mutually exclusive conditions.
- Further research is needed to understand the complex relationship between TBI and PTSD.

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.

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...
Amnesia
Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...

Dissociative Amnesia
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...
Repressed Memory
Repressed memories are a psychological phenomenon where memories of traumatic events are unconsciously blocked from a person's awareness. This process occurs as a defense mechanism, protecting the mind from the emotional impact of distressing or painful experiences. For example, a person who has experienced childhood trauma may grow up with no conscious recollection of the event. In such cases, the memories are thought to be buried deep within the subconscious, inaccessible to the conscious...
Flashbulb Memory
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 where...
