What is retrograde amnesia ? Amnesia is the name given to a disturbance in the ability to recall stored memories . It is usually caused by disease or head injury , but in rare cases can occur apparently spontaneously . The memory loss associated with amnesia can include everything from a person 's past or just portions of it . In most cases , it is a temporary condition , lasting from a few seconds to a few hours . But in severe cases , it can last months or even years . There are several different types of amnesia . Retrograde amnesia is an inability to remember any events that occurred before the accident or illness . The leading hypotheses are some form of epileptic event , a problem with blood circulation around , to or from the brain , or some kind of migraine-like phenomenon . Usually , the affected person can not remember events shortly before their accident or illness at all , but their memories of the distant past are intact , and there is a gradient of memory loss between the two extremes . Retrograde amnesia often lasts for a year , before the patient starts to remember things .
