[英文釋義] A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals,and episodes may last from minutes to hours. During the period of amnesia,immediate and recent memory abilities are impaired,but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs,and recurrences are unusual.
