Memory loss

Memory is the function of reinstating the information stored in the brain in consciousness, and it is the process of preserving and recalling past experience. There are three basic processes of memory: ① cognition, the process of making experience leave traces in the central nervous system. It depends on the level of awareness and concentration. Fatigue, lack of interest, inattention, and blurred consciousness can affect the process of remembering. Serious memory defects are usually caused by organic causes. ② Save, that is, information storage. There are three stages. The first stage is the formation of memory traces through sensation, which are very unstable; the second stage is short-term preservation; the third stage is long-term preservation. Preservation is a characteristic of nervous tissue. When preserving is impaired, new memories cannot be established, and the range of forgetting is increasing day by day. Severe preservation defects are found in organic diseases of the brain. ③ Reproduction, the process of awakening and re-presenting past experience. Partial or complete loss of the ability to reproduce past experience is called forgetting. Forgetting occurs when one or all of the three basic processes of memory are damaged. Memory loss is seen in the neurological symptoms of Whipple's disease.
