Amnesia is loss of memory, through injury or illness. Suffer amnesia, temporary amnesia, complete amnesia.
Real cases rarely look like the film version: people usually lose the ability to form new memories rather than their whole identity. Retrograde amnesia loses the past and anterograde amnesia loses the future. Note the Greek, meaning forgetfulness.
