Memory is usually defined as to have or keep what experienced in the past in the mind and recall them when necessary. On the other hand, we know the content of memory can change more or less into something different from the objective facts. In that sense, memory is not a process like recording a video tape or taking a picture, always reproducing precisely what was recorded. Memory is a dynamic process influenced by a lot of biological, psychological and sociological factors. So we can simply define memory as remaining something of the past influence in the mind.
Amnestic syndrome is one of the most important clinical signs. In a narrow sense, amnesia or amnestic syndrome defined as loss of memory or disability to keep it in the mind and remember what was experienced. In organic mental disorders including dementia and Korsakoff syndrome, amnesia is a cardinal sign. On the other hand, loss of memory plays and significant role in normal aging process, some psychogenic disorders (psychogenic amnesia, psychogenic fugue, depersonalization, and neurosis) and endogenous psychosis (depression and schizophrenia). We can also find some other psychopathological symptoms accompanied with amnesia.
This study consists of three parts. The symptomatogy of amnestic syndrome is described in the first part, where we discuss a lot of mental disorders to show what their memory problem is like and how they are related to other symptoms. In the second part, 11selected clinical cases are shown. In the last part, literatures on amnesia of recent years (from 1990 to 1999) are classified into several chapters from the viewpoint of clinical psychopathology.
