One such marker is a beta-amyloid deposit which is a protein that deposits on the brain ...

The neurological cause of psychogenic amnesia is controversial. [5] [7] Even in cases of organic amnesia, where there is lesion or structural damage to the brain, caution must still be taken in defining causation, as only damage to areas of the brain crucial to memory processing is possible to result in memory impairment. [7]
This evidence for delayed and impaired recall of trauma due to the trauma itself is contrary to the concept of 'repressed' memories, wherein traumatic memories are stored, intact, in the memory in order to 'protect' the subject and are able to be 'recovered' with full accompanying narrative. [46]
One such therapy is trauma-focused therapy. This therapy involves bringing the most disturbing elements of a traumatic memory to mind and using therapist-guided cognitive restructuring to change the way the memories are thought about. The change in evaluation usually involves highlighting that the feelings of certain death, extreme danger ...
