Amnesia is partial or complete loss of memory . It occurs following concussions,in dementia,hysteria and head injury.
In amnesia,recent memory and the ability to form new memory are profoundly impaired by injuries to the limbic memory route.

* The limbic system is a part of the brain involved in the regulation and control of psycho affective behaviour*

Types of Amnesia:-
----------------------
# Aterograde Amnesia --> It is loss of memory for those experiences and events following the physical or psychological trauma.

# Catathymic Amnesia--> It is memory loss limited and confined to a certain recollection or experience

# Circumscribed Amnesia--> It is memory loss in which the beginning or the termination of the memory loss is fairly easily defined

# Infantile Amnesia--> It is loss of memory for the years from birth to about 5 years of age

# Retrograde Amnesia--> It is loss of memory for those events and experiences preceding the cause of the amnesia.
