Introduction:
Dissociative amnesia (DA) is a retrograde amnesia characterized by an alteration in episodic memory.
Aim:
Establish the neural bases which underlie the development of dissociative amnesia.
Methods:
Systematic and evaluative bibliographic review of qualitative type.
Results:
The bibliography found suggested functional inhibition in the hippocampus, amygdala, temporal lobes, prefrontal cortex and thalamus. Also, hypoglycemia was observed in right cerebral cortex, at the fronto-temporal junction. An inhibition in the potential action P300 was also stated.
Conclusions:
There is enough evidence to say that dissociative amnesia is an objectifiable biologically based pathology. There is a need to review the current conceptualization of this syndrome and to establish new criteria that would allow us to distinguish DA from organic amnesias.

Amnesia
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...
