The first kind of amnesia is retrograde amnesia, and this is the most common type which are presented in TV shows, hospital, and stories. This is where a person damaged their temporal lobes and especially the hippocampus.

Patients with retrograde amnesia are unable to recall memories from the past occured before it is presented, but the ability to form new memories and recall after the start of amnesia is not affected. The second type of amnesia is anterograde amnesia which is the reverse-side of retrograde amnesia. “This is caused by the damage to hippocampus or surrounding cortices, disabling memory formation, and often it is permanent if the brain is damaged.” Patients with anterograde amnesia are unable to form new memories from the point when it is presented and to recall memories recently formed because information is not moved to the long term memory. The last type is global amnesia, and this is a temporary total loss of memory and the patient affected is unable to recall any information restored in memory. Out of the nine causes there is the sudden trauma in the head that can lead to amnesia.
