What is retrograde amnesia?
Retrograde amnesia refers to the loss of information acquired before amnesia while anterograde amnesia (AA) is an impaired capacity for new learning. RA is usually the result of damage in different parts of the brain accountable for controlling emotions and memories. The condition or the severity of retrograde amnesia entirely depends on the cause.
What are the 2 types of amnesia?
– Generalized amnesia – When the amnesia involves the person’s whole life. – Localized amnesia – no memory of a specific traumatic event that took place – Selective amnesia – remembers only selective parts of events that occurred in a defined period of time. – Systematized amnesia – memory loss regarding a specific category of information.
