What is one way that people get retrograde or anterograde amnesia? Retrograde amnesia commonly results from damage to the brain regions most closely associated with episodic/declarative memory the temporal lobes and especially the hippocampusRetrograde amnesia is caused by trauma that results in brain injury. Critical details of the physical changes in the brain that cause retrograde amnesia are still unknown. Retrograde amnesia is often temporally graded, meaning that remote memories are more easily accessible than events occurring just prior to the trauma. Events nearest in time to the event that caused memory loss may never be recovered. Anterograde amnesia it follows a traumatic brain injury in which there is usually damage to the hippocampus or surrounding cortices. Amnesia is seen in patients who, have parts of their brain removed that are known to be involved in memory circuits, the most notable of which is known as the medial temporal lobe memory system. Anterograde amnesia is also a common occurrence among alcoholics and people who have consumed a large dose of alcohol. It generally occurs when the blood alcohol level reaches above .25 percent, and is usually accompanied by a hangover.
