Psychogenic amnesia is called dissociative amnesia in psychiatric terminology . The main characteristic is memory loss, usually of important recent events, and amnesia is usually partial and selective and usually revolves around a traumatic event, such as an accident or the unexpected death of a loved one. The degree and extent of amnesia varies from day to day, but there is always a fixed core of content that is never recalled during the waking state. This type of amnesia is not associated with organic damage to the brain. To put the above definition in plain language, it is psychogenic amnesia, not because of brain injury, but because of a major psychological trauma, resulting in selective forgetting of certain people and events, with no problem with memory itself. It is worth clarifying that this selective amnesia is not a conscious fraud, but a real psychopathological phenomenon that occurs at the subconscious level and is not governed by the person’s subjective will. Some of them may improve on their own and rarely last more than 1 or 2 days. The key to treating psychogenic amnesia is to gradually come to terms with the traumatic experience. Patients should shift their daily attention and focus of life from trying to remember the past to the present and future life, gradually accepting the incomplete memory, cherishing and feeling the joy and hope of the present life, which is more helpful for the recovery of the disease.
