Retrograde amnesia (RA) refers to loss of memory for information acquired before the onset of amnesia. The condition is commonly observed after medial temporal lobe or diencephalic pathology, and it has fascinated psychologists, biologists, and clinicians for over 100 years (Ribot, 1881).
In this article, the focus is on using PTA (both retrograde and anterograde) as salient indicators of traumatic brain injury severity and the most reliable index of outcome prediction, even in mild cases.
4 Σεπ 2024 · This paper reports a reassessment of published literature on the question of whether retrograde amnesia data from patients with severe trauma supports the idea that there is ongoing consolidation of long-lasting memories.
Amnesia can be retrograde (that is, loss of memories acquired prior to onset) and anterograde (impairment in forming new memories), and patients typically exhibit both forms to varying extents.
1 Ιαν 2018 · Retrograde amnesia is the inability to retrieve experiences, facts, or concepts that were acquired prior to the causative disease or trauma. The loss of memories may be partial or complete. Retrograde amnesia is almost always present to some extent in individuals who suffer from anterograde amnesia.
The nature of retrograde amnesia (RA) in brain disease is a particularly intriguing problem. Recent research has emphasized differing patterns (dissociations) of memory loss in RA. Less emphasis has been placed upon impor-tant associations (correlates) of retrograde memory loss, which may contribute to or explain these differing patterns.
Retrograde amnesia has a basis which is (at least partially) independent of anterograde amnesia - in some patients, it appears to involve a failure to reconstruct past experience from contextual cues, and this may reflect a superimposed frontal dysfunction.
