Amnesia
Symptoms of Amnesia
Depending on the severity of the damage, amnesias can last for minutes, hours, or longer. Sometimes memory is lost suddenly but temporarily (called Transient Global Amnesia ). Some people recover their memory without treatment. However, if brain damage is severe, the ability to form new memories may be lost. Affected people are more likely to remember things from the distant past. For example, people may remember their spouse from their first marriage but not the current marriage.
